This is a technical advisory regarding the installation of solar central heating systems and consideration for correct operation within a particular building design.

This advisory is to provide advanced technical information regarding the installation, operation and design of Surface Power solar central heating systems, (note: solar central heating systems also do hot water). This advisory only considers retrofitting houses. (new builds have different design requirements and more options)

MENU:

• House legacy design issues
• Do everything in one go
• What you will save financially?
• How it all works?

 HOUSE LEGACY DESIGN ISSUES.

Existing houses have a number of design issues, your building may have some of these issues and they will all cost you money in wasted annual heating energy bills.

• Poor attic and cavity wall insulation.
• Poor heating pipework insulation.
• Boiler located outside in the yard.
• Boiler located in an outside shed. (is your car warmer than you ?)
• Old inefficient boiler

BUT what you may not realise is that your boiler can become even more inefficient after you upgrade your insulation AS it now will be switching ON and OFF more often. It is therefore very important that you complete a few tasks at once when considering a Solar Central Heating upgrade.

With English, Scottish, Welsh & Irish climates, we have very benign weather relatively speaking impacting the design. If you want more detail as to why we design systems this way, have a look at our blogs in relation to these subjects, they are discussed in detail. Just as you cannot install a solar heating system design from Arizona in the UK & Ireland, you also cannot install a solar central heating design from the UK & Ireland in Arizona (or anywhere else). These systems are all interlinked with the local climatic conditions, and cloud is the predominant condition in the UK & Ireland.

DO EVERYTHING IN ONE GO.

By doing all the small jobs with the big job in one go, you get the best return on your investment. So if you do the following and you complete it according to our guidance, you will save over 50% of your annual heating & hot water energy bills.  (note, this only apply’s to our high temperature solar systems).

Do the following in one go:

• Attic insulation up to 300mm
• Cavity wall insulation, upgrade with bonded bead even if you have areaboard inside it
• Your boiler loses heat energy in 3 ways:
1. By being outside and cooling down when it shuts off & heating up when it turns on
2. With losses through ground pipes which will be poor insulators
3. With poor conversion efficiencies of 50% for 10 year old boilers.
• When you install Solar Hot Water &/OR Solar Central Heating, you should include a new smaller internal boiler in the house where possible which will remove loses 1 and 2, improves 3 and it also makes your solar system contribute a higher percentage of FREE heat energy.
•  These items will help you achieve a 50% or greater reduction in your heating energy requirement AND make your home more comfortable.
• Also, note if the winter is very cold & frosty like the last couple of winters, your solar input will sky rocket with a Surface Power solar system as it does not matter what the outside temperature is.

Doing everything in one go is the cheapest way to do all this work. To change the boiler, you have to DRAIN down your heating system. To install your solar cylinder, you have to DRAIN down your heating system. Doing it at the same time saves you ALOT OF money.

 WHAT WILL IT SAVE YOU FINANCIALLY?

Using current customers data which is now 5 years plus, you will save 50% or more, some of our customers as profiled are saving much more than this annually but we will stick to the 50% or more as a safe measure. This means that you can pay for these installations in approx 5 years with the savings and then the next 25 years gives you excellent annual addition cash to spend instead of wasting it on fuel bills.

This is what you waste your energy on, do you recognise anything ?  

1. If your boiler is in the shed/garage, you waste up to 15%, after you insulate the house better, you waste up to 20% of your oil/gas.
2. If your boiler pipework coming across the yard does not have the new type of super insulated pipework, it wastes up to 10% of your oil/gas.
3. If your cylinder is not a factory insulated unit, (ignore lagging jackets on standard copper cylinders), it loses heat overnight and will require your boiler on in the morning to top up the cylinder (see points 1 & 2).
4. If your attic is not insulated, your room heat rises into the attic, typical symptoms in cold weather are WARM HEAD and COLD FEET. Up to 30% of your energy lost.
5. Uninsulated cavity walls lose up to 25% of your heat.

Every winter and summer when you use your oil or gas you are wasting energy. Remember, even with a Surface Power solar hot water system in summer, your boiler should be off all the time even when the weather is not great. You do not need any sunshine for it to work.

HOW IT ALL WORKS.

This applies to ALL legacy houses that are of standard build and construction in the UK & Ireland. If the house was built before 2006, it will achieve much higher savings than stated typically.

By installing a Surface Power Solar Central Heating system you will be trying to adjust your buildings profile from the following typical profile:

1. Annual Hot Water Energy Usage – 40% of TOTAL; after upgrade down to 10% of TOTAL (includes reductions in direct and indirect boiler use for heating hot water), 30% FREE.
2. Annual Heating Usage to heat up your equipment – 30% of TOTAL; after upgrade down to 10% of TOTAL (i.e. boiler, pipes, walls, floor, etc), 20% FREE. 
3. Annual Heating Usage to maintain the heat after the system has heated up (2) – 30% of TOTAL; after upgrade down to 20% of TOTAL, 10% FREE.

This would give a saving of approx 60% off you ANNUAL HEATING BILL BUT if you moved your boiler inside, blocked unused chimneys, etc, this could be greater.

NOTE: We advise our installer network to give our customers a good understanding of this information so they can do a complete upgrade which meets “best practice”. 

 BACK TO THE SOLAR CENTRAL HEATING & HOT WATER SYSTEM UPGRADE.

Note: A Surface Power Solar Central Heating system contributes to hot water and central heating energy.

MYTH 1: Does this mean I don’t need a boiler, solar will provide all my heating? ANSWER: In the UK & Ireland, NO, (although that can happen if the day was really sunny and the night is cool enough to warrant some heating) but the solar system integrates with the oil/gas fired system. Its about your TOTAL energy at the end of the year. (for example. Your Total Energy = 100%, and that is broken down into 65% FREE Solar + 35% oil/gas = 100%.)

 MYTH 2: If I install an 800L buffer tank, I was told that it will run my heating system because it can store a large volume of solar water. ANSWER. NOT likely in the UK or Ireland, unless you are happy to heat your house with a large cylinder of cold water in winter. The solution for the UK & Ireland is high power solar systems into concentrated stores, don’t forget a 300L cylinder heated to 80C will provide the exact same amount of heating roughly as an 800L at 40C BUT the 800L cylinder will ALSO not heat up your hot water high enough in spring, summer and autumn without a commercial size solar installation and/or oil and gas running. (This is a solution for another country most likely with a different weather pattern, big cylinders need blue sky sunny summers guaranteed )

INSTALLATION STARTS HERE:

STAGE 1: Remove the existing cylinder and replace with a SPSCHBuffer/Hot Water cylinder, size will vary on house but typically 300L up to 3000 sqft. There is a size that will fit into ALL houses even small ones with small hot presses. 

STAGE 2: Connect the boiler directly to the SPCHXXX Cylinder as the boiler will no longer feed the heating circuit directly. If your boiler is in the shed, this is an ideal time to get a low cost smaller internal boiler which will also be of higher efficiency. (If you have upgraded your insulation, your boiler can be a smaller kw model)

STAGE 3: This cylinder will have 2 stats controlled by your familiar HOT WATER ON and HEATING ON switches. This means that you have a low temperature hot water stat set at 40C at the top of the cylinder which calls the boiler ON whenever the top of the cylinder is below 40C. Your solar will produce this first of course but you may use alot of water at night and need a quick boost, boiler runtime is extremely short but in reality, you will have a full cylinder of hot water typically unless the weather is really bad (winter like). Also, as you do not have to meet Legionaires requirements (min of 60C hot water)  in this design, you save even more energy which would have been wasted. (your existing oil/gas boiler can’t be set below 60C, have a look). With this design, your boiler has a 60C MIN TEMP stat but the cylinder switches off the boiler when the hot water stat reaches 40C (providing the hot water switch is turned on).

STAGE 4: The 2nd cylinder stat is the Heating ON stat placed at the middle of the cylinder and this will call the boiler ON when the water is at 50C or lower in the middle of the cylinder (providing the heating switch is turned on). Note: As you increase the insulation of your home, you can actually run your radiators (or underfloor) at lower temperatures to get the same result with even lower energy. 

TECHNICAL SPECIFICATION.

FAQ LIST…

Q: Is my cylinder full of hot water for my showers?; A: YES & NO, technically it is full of central heating water but there is a coil where your domestic hot water runs through, this takes heat from the cylinder water as it passes and delivers hot water as normal. It is simply the reverse of how you would normally heat a cylinder. It means that you no longer have to waste energy heating hot water to 60C for legionaires legislation when all you need is 40C for showers, etc.

Q: I have a regular terraced house, can this be installed?: A: Yes, it can be installed in any house, of any size, with any pre-existing system.

Q: Does this cylinder replace my existing hot water cylinder? A: Yes.

Q: Will there a significant additional works required versus installing a standard solar hot water system? A: NO, 95% of the work would need to be completed in a standard solar hot water system install.

Q: Will my house still work the same way? A: Yes, but with lower bills and ample amounts of FREE hot water.

Note: This is not a design for any other solar system, Surface Power solar systems are high temperature and high performance, this design specification has been perfected by us since 2005 and typically produces in excess of 50% savings in annual heating bills. (highest recorded in Ireland, 85% reduction, see case study in blog).

This is a technical advisory regarding the installation of solar systems where there is a solid fuel hookup required in the building.

We sometimes issue advisory’s where there is evidence of a practise in the solar installation industry which we feel may lead to an incorrect installation design in solar hot water systems primarally (as we must approve all solar central heating designs, that type of installation is a lower risk).

This advisory relates to the CORRECT DESIGN of solar hot water cylinders for use with OUR solar systems where a solid fuel input is also required. Surface Power Solar systems run at high temperature and a HIGH Delta T and are unlike low temperature solar systems from other manufacturers.

THIS ADVISORY OUTLINES THE CORRECT METHODOLOGY FOR CYLINDERS WITH A SOLID FUEL INPUT.

Diagram 1 below outlines the design of a solar cylinder which correctly shows the boiler input coil on top and the solar input coil at the bottom. Sizing rules should be followed as normal.

However, when adding a solid fuel coil to the cylinder, you should NOT push it in between the solar coil and the boiler coil. IT SHOULD BE ADDED TO THE BOTTOM OF THE STORE AS IN DIAGRAM 2 above.

The following DIAGRAM 3 is the INCORRECT way to integrate solid fuel into one of our solar systems. 

 When you are designing a solar system for a house with solid fuel input, you need to design the cylinder in 2 stages:

Stage 1: FORGET the solid fuel input for a moment, just consider the building as if it ONLY has a solar input and a boiler (gas/oil) input. Design your cylinder size based on these criteria only. See the next Diagram 1 again.

Stage 2: NEXT, you consider the solid fuel input. This will go onto the end of the cylinder BELOW the solar coil.

If you worked out that your solar hot water installation was a 200L/250L, you may add an extra 50L-100L for the solid fuel coil at the bottom of the cylinder.

The correct format is the following one for the inclusion of solid fuel:

The following profiles were taking from a customers system with their permission on July 24th.

The following information from a customers system highlights HOW a Surface Power solar system produces its energy from daylight ONLY. In the following post. you can see that, this customers system is capable of producing a FULL cylinder of usable hot water (40C) EVEN though its been drizzling/raining with heavy low cloud since 7am.

This video shows the weather on the ground 

This screenshot shows the system in production at 10:59am

Here is a view of the telemetry for this system. By 11:03am, the system has achieved a Delta T of +7C EVEN though it is still misting heavily and has been for hours with deep low cloud.

It is this technology breakthrough from Surface Power which allows exceptional performance for Solar Central Heating & Hot Water EVEN in cloudy climates. Legacy solar collectors have been designed IN sunny climates FOR use in sunny climates. Old solar collector science is NOT designed for maximum production in cloudy climates (using light only) as Surface Power’s technology is.

How many other solar manufacturers will show you the REAL data from their systems on the ground. Surface Power is the only solar manufacturer that can prove it’s technology delivers day after day 24/7 publically. See our live customer systems online at www.surfacepower.com round the clock.

Simple, when it uses daylight and not sunlight as its primary energy source. That’s what you get when you use Surface Power solar systems which use our patented thermodynamic laminar solar technology. A northerly facing solar hot water system has no sunlight option NOR has it strong light levels to use for energy which come from the South (when in the northern hemisphere). The reason it works EVEN better facing NORTH than competing systems facing South is DAYLIGHT power.

See below the outstanding power of a Surface Power Solar System facing a Northerly direction in the UK in the morning when sunlight OR strong daylight when cloudy IS on the COMPLETELY OPPOSITE side of the building.

AT 10:04 AM in the morning, this standard system, an SP501PRO-N is producing more power than a South facing solar system at 12 noon at the height of a sunny day.

AT 10:07 AM in the morning, this standard system, an SP501PRO-N is producing more power than a South facing solar system at 12 noon at the height of a sunny day with a Delta T (temperature difference of 9C).

AT 10:10 AM in the morning, this standard system, an SP501PRO-N facing a northerly direction has produced a rise of 3.1C in the bottom 150L of the cylinder, equating to an energy input of 557.8 w/hours OR in simple english the same as having your immersion on for a half an hour.

TO REPEAT IN CASE YOU MISSED IT: This Standard Solar System FACING A NORTHERLY DIRECTION delivered an equivilant of a half hours worth of electric immersion element heating into the cylinder in LESS THAN 6 MINUTES for FREE using light only (as of course the system is facing AWAY from the direction of the SUN.)  

This is another example of how our solar system’s can outrun electrical immersion heating EVEN when they are facing a Northerly direction in the UK and Ireland (in a week with not great weather).

 When we say we use DAYLIGHT to make energy, we only say it BECAUSE we can prove it !

The MYTH is over, South Facing roofs are NO longer required for solar thermal. See the North facing Case Study below.

Surface Power’s next generation solar technology gives superb power performance over legacy solar panels and does not require south facing roofs. This high power solar technology allows new uses for solar thermal such as FREE input to your central heating and FREE input to your hot water systems to collapse those energy bills.

Surface Power’s leading solar thermal technology is reshaping the way solar systems are installed, designed and utilised. After 3 years of installing systems facing into the North Pole, (i.e. the northern facing direction), Surface Power has been challenging the old methods associated with legacy solar hot water systems which need to face the sun (south facing).

The reason why Surface Power can install solar hot water systems successfully in a Northerly direction is down to the high performance output using daylight (our patented thermodynamic laminar flow solar technology) coupled with our patented MPPTt (maximum power point tracking technology – thermal). Daylight is found every direction, sunlight is only found in high amounts facing south.

July 15th: weather cloudy.

PICTURE 1: Here is a Case Study of a UK system facing North West. This screenshot was taken at 8:06am in the morning and the Delta T is already at +10C between the collector and the hot water cylinder. This is more power transfer (kWhrs) than a typical standard solar system at the height of a summers day.

PICTURE 2: The next screenshot is from the same system at 9:02 am. In less than an hour, this North West facing system has increased the cylinder temperature by +6C, and this is before a typical legacy solar system would start any daily production EVEN if it was facing south. 

PICTURE 3: The next screenshot is the same North West facing system at 11:14am where the hot water has now increased in temperature to 45C. This North West facing system is showing the extraordinary heating power that Surface Power derives from daylight versus what you would expect from any other solar hot water system which must face south.

PICTURE 4: The next screenshot is the same North West facing system at 4:15pm where the hot water has now increased in temperature to 76C. This North West facing system is still maintaining a Delta T of +10C showing the power that Surface Power derives from daylight. This Surface Power Solar system has produced more energy (kWhrs) facing a northerly direction than a typical legacy solar system of similar size would produce facing south.

July 16th: weather very cloudy, showers and rain.

PICTURE 1: Here is a screenshot of the next day of the same Surface Power system facing North West. This screenshot was taken at 1:11pm in the morning, weather is not great and the hot water cylinder has been heated to 32C.

PICTURE 2: This next screenshot shows that by 4:40pm, the water in the cylinder exceeded 60C even though the system faces North West and the weather was poor.

July 17th: weather very cloudy, windy, showers and rain.

PICTURE 1: Here is a screenshot of today (17th July) of the same Surface Power system facing North West. This screenshot was taken at 4:41pm in the evening, weather is poor across Ireland & the UK, probably one of the worst days of the summer so far and the complete hot water cylinder has been heated to 55C. The cylinder finished the day at just under 60C even with the day’s bad weather and the system facing a Northerly direction.

This system outlines how powerful a Surface Power solar system is and how it’s new technologies overwhelm old style solar technology. EVEN North facing Surface Power Solar systems in mediocre weather can deliver OUTSTANDING performance results.

 That makes our systems ideal for use in central heating AND hot water applications. These are applications where we have vast experience.

In an ongoing 3 year comparison study being electronicly recorded every second; the performance of a  comparable Surface Power solar hot water system and a leading European solar vacuum system has just passed the 3 year mark and the 3rd years data is confirming the same ongoing results. The Surface Power system is a customer’s system and the leading European solar vacuum system is also a customer’s system where data is being collected from both systems remotely for comparison reasons. This is the first time we have released any data from this study.

A review of the all the data shows exactly how significant developments in the design and operation of Surface Power’s solar hot water DFNMT and MPPTt technology completely changes the performance characteristics of solar hot water; & more importantly its contribution to combined solar hot water & central heating systems.

THE RESULTS: (see data and system details at bottom)

In direct comparisons, day for day over 2010/2011, the Surface Power solar hot water system produced 392% kWhrs of energy when compared to a similar sized leading European installed solar system, that is nearly 4 times more energy per sqm installed.

The seasonal data was:

• In Winter (Dec/Jan/Feb); This was 243% of kWhrs of energy when compared.
• In Spring (Mar/Apr?May); This was 372% of kWhrs of energy when compared.
• In Summer (Jun/Jul/Aug); This was 430% of kWhrs of energy when compared.
• In Autumn (Sep/Oct/Nov); This was 350% of kWHrs of energy when compared.

It should be noted that the Surface Power system didn’t record a single overheating event (even though holiday controls exist) but the other system did record such events. This highlights the much higher amount of power coming from lower light levels, cloud and poorer weather conditions from the Surface Power system.

Q: What are the main differences between legacy style solar hot water systems and Surface Powers, DFNMT and MPPTt technology ?

A:  There are 3 main components to the design of a solar hot water system, get any one of them wrong and you could have wasted your investment…

1.  the solar collector,
2. the transfer system
3. the heat exchange process.

1)..SOLAR COLLECTOR…The Surface Power solar collector has been certified in system testing using TRNSYS modelling by different independent certification bodies as part of different government accreditations as being somewhere between 85% and 2200% of energy output when compared to existing or legacy solar collector designs BUT this is not where all of the energy comes from. “Too much emphasis” is placed on solar collectors ONLY with little thought for the FULL SYSTEM and controls science.

Existing solar systems can suffer from issues with stagnation, stalling and overheating. All you need to do is read about different solar panels, and you can probably figure out which ones suffer from overheating the most; by the amount of time they devote to talking about the issue as well as trying to “solve the issue” in their own products. Surface Power solar systems DO NOT have to deal with overheat  as the technology is optimised for low light level “grunt”, cloud, dullness, winter, etc and MPPTt reduces the power band when the water gets above 80C.

2).. SOLAR SYSTEM DESIGN…Surface Power solar systems use several patented technologies, one being, DFNMT, or solar laminar thermodynamic science, which means you get up to twice the power from the system flow. This patented laminar technology is only present in a Surface Power solar hot water system as it doesn’t work with any other solar system design.

3)… MPPTt (maximum power point tracking – thermal)…The patented heat transfer science, MPPTt, is another key aspects to Surface Power’s performance and this delivers up to 7 times the typical performance of legacy type DTC (differential temperature control). Whereas legacy solar hot water needs to operate at low power to stop overheating and stagnation, Surface Power’s solar technology thrives on it and can operate with very high power bands in ranges which rival an oil boiler or gas boiler at times. MPPTt also only works with Surface Powers solar as it uses the ability to create high power bands, these high power bands cause stagnation and stalling if used in legacy solar systems.

If you observe any online Surface Power system, you will commonly see the Delta T (temperature difference) between the collectors and the bottom of the cylinder heat exchanger) between +10C (dark cloud) and +25C (blistering sunshine). This means for the same collector array, MPPTt (maximum power point tracking – thermal) is delivering many times more energy a day than standard solar hot water systems. This Delta T will drop back below +10C after the cylinder typically hits 70C or higher so as to reduce the power band.

WHEN YOU ADD ALL THESE PERFORMANCE INCREASES TOGETHER, 1) Solar Collector, 2) Thermodynamic Laminar Flow Science and 3) MPPTt, you get many times more performance. This current comparison study shows that in a non sunny climate like Ireland and the UK, we are averaging a performance advantage of nearly 4 times.

Have a look at the following screen shots BELOW from today in CLOUDY WEATHER, have you ever seen Delta T’s of between +10C and +20C as standard and todays’ weather is very cloudy. Ask around, LEGACY solar hot water systems start pumping at +7C and then drop in temperature to +3C and turn off, and stay off until they heat up again, (VERY LOW POWER), but they need to do this or they will suffer from stagnation and overheating. Even in sunshine they typically have a maximum DT of +5C. Surface Power will have a DT of up to +25C in direct sunshine, this high power band would cause chaos in a legacy type solar system.

However, Surface Power solar systems take advantage of this and deliver high power with several patented advances in its systems.

SYSTEM BELOW HAS Delta ‘T’s of +14C to +18C on a system today over a 45 mins period.

This is one of the reasons why it is very important to upgrade your insulation when you have a hot water system from us.

We can make ALL your hot water most days that you need your central heating on, so it’s best if you can maximise the amount of days your boiler is OFF. It will slash your energy bills and make your house more comfortable and you’ll have loads of FREE solar hot water.

 SOLAR CENTRAL HEATING SYSTEMS

 There is no standard format to solar central heating systems. It all requires a complete look at how you live, what your home already has installed and what you want to achieve. Whilst we won’t hide that we have a very successful history in Solar Central Heating system through our installer network, we regularly say NO, in fact we say NO to over 50% of requests for Solar Central Heating system designs from our network.

UNDERSTAND THE REASONS WHY WE SAY NO BEFORE YOU CONTACT US

 # We don’t care if you seen it working that way in Hamburg, we have different weather. Get someone in Hamburg to design it and stand over it. The reverse also applies in that we would NOT recommend something designed for the UK & Ireland for Hamburg.

# If you’re house is poorly insulated, this works against Solar Heating. Solar efficiency is greatest when your boiler is OFF the longest. If your upgrading your insulation at the same time as installing a solar central heating upgrade, well, that’s different.

# It is NOT possible to put in a 20 gazillion litre hot water buffer tank, heat it with solar hot water and get it to run your radiators/underfloor all night instead of your boiler AND have loads of solar water in Ireland OR the UK. This is a typical central european design, we have a different design requirement here. We do not get clear frosty sunny skies in winter as our typical weather.

This winter is being predicted to be one of the hardest and coldest on record, Gas in the UK AND Ireland announced to go up 30% for this winter in the last week, all other fuels will follow suit, are you ready to pour more of your money down the drain.

To talk to one of our network or discuss a solar heating & hot water requirement, contact us, its Free, Surveys are Free and don’t worry, we’re likely to say NO before you do, but if we say YES, then it’s because you’ll join the many people who we are helping cut their home heating fuel use by 50%  or greater a year. Email sales@surfacepower.com

Did you know that in 5 years time, 50% of your home heating bill will probably buy you a new family car.

 Technical details:

Surface Power SP501 Pro, full year round hot water system. All performance measurements on both systems were made using the First Law of Thermodynamics, (mechanical mathamatical calculations based on the heat rise of the hot water cylinder at 1 second intervals for over 3 years, NO consideration was given to the solar systems and no data was taken from either solar system as regards performance). Performance has been determined by the heat rise in each cylinder AFTER ALL losses ONLY. Both systems are under the control of customers and Surface Power has no direct access nor involvment in the third party data other than access via its public access. The study has remote access to read the data ONLY in both locations.
