A typical system costs from £3500* for a 2-3 person household if a suitable cylinder is already in place. Larger systems, including a new cylinder, are likely to cost from £5000*
This can vary substantially, depending how you currently heat your water and how much you use and how much sunshine there is in a given year.
We would be happy to look at you case in detail. A solar water heating system is one of few home improvements that may not only add value to a property, but also save you money over the years.
You may be entitled to a Government RHI payment if you have a solar water heating system installed. Typical Domestic total income from £1500 to £3000.
Many estate agents consider solar water heating will make a house more “saleable” and may have a small positive effect. Even a 1% increase is often likely to be greater than the cost of the system. We would always recommend you seek specialist advice on this matter.
The solar water heating system requires an economical low power pump to run in order to supply a larger amount of energy from the sun. This is all achieved within your home, so less energy needs to be produced elsewhere and then transported to your home. Consequently there can be a substantial net saving of energy produced by power stations that emit large amounts of Carbon Dioxide and other pollutants.
If your roof faces South/East or South/West a system will still work, but a few percent less efficiently. We can simply install a slightly larger panel to counteract these losses. If your roof faces East/West a twin pump / twin panel system can be installed, or we can simply oversize the solar panels to compensate.
Planning permission is not normally required (other than in conservation areas). You should always check with your local planning department (we are happy to assist you in doing this).
Evacuated solar tube panels are made of tough Borosilicate glass evacuated tubes (similar to Pyrex). They are designed to last in excess of 25 years, so the energy consumed during its manufactured is a tiny fraction of the energy that they will produce over their service life.
Though very high temperatures can be achieved in the panel, it’s heat is then transferred into a water cylinder where the temperature is regulated. Over-pressurisation is neutralised by an expansion vessel and the system is protected by a pressure relief valve.
The solar panel is most productive during the summer months and on sunny days, at times providing all of the hot water required. However, on overcast days and during the winter it makes a valuable contribution so that the boiler will have less work to do than if it had to heat mains temperature from cold water.
There are some special skills and equipment required to install your own system. It is advisable to attend a training course to complete a whole installation. However, substantial savings can be made if the panel and control system are installed professionally and the competent DIY enthusiast installs the tank and pipe work themselves.
Yes. Many people consider flat “in roof” panels to be more aesthetically pleasing and these can be used in the place of evacuated tubes. However, as they are less efficient, more of the roof would need to be covered to make the same contribution in the summer and they are substantially less productive during the winter.
We are a local company who specialise in solar water heating. We charge a fair price for quality installations. We have low overheads due to small marketing budgets and do not employ high commission sales staff.
The whole system is guaranteed for 2 years from commissioning with a free service / check after one 4-6 weeks, one and two years included.
Certain components are guaranteed by the manufacturer for longer e.g: the tubes for 10 to 20 years.
The only running cost is the electricity to run the circulation pump, approximately £8-10 / year.
An annual service is recommended at a cost from £75 /year (free for the first 2 years if system is installed by us).
Solar can be made to be compatible with most combi boilers. Please contact us, and we can show you exactly how.
The boiler rarely needs changing but the cylinder often does.
Solar water heating is particularly effective for swimming pools and the pay back period is often even faster than on domestic water heating systems.
The panels are not very heavy (typically 40 Kg) and can usually be installed safely on a flat roof.
There is normally only one moving part (the pump, which tends to be very reliable, when pumping clean inhibited antifreeze/water mixture) so there is little to wear out or go wrong with a well installed system.
We carry £2m public liability insurance.
We carry out solar servicing and repairs to all makes of panel and make sure they are running efficiently. We clean / check / flush / re-pressurise sstem swith new inhibited solar anti-freeze.
The antifreeze solution in the system is a mixture of water and propylene glycol and non toxic.
Yes, but only at 5% for installations. (20% for repairs).
