Next steps on Renewable Heat
On 20th September 2012, the Department of Energy & Climate Change (DECC) launched a series of consultations on the domestic RHI which is scheduled to start in the Summer of 2013. This page will be updated with more accurate information soon but in the meantime, please click here to learn more.
Solar Thermal (Hot Water)
What is Solar Thermal?
Solar Thermal systems transform the sun’s energy into hot water.
An increasing number of households across the UK use the technology to save on the cost of water for bathing and washing.
These systems offer an environmentally-friendly alternative to heating water using fossil fuels and are carbon emission-free.
Solar Thermal (Hot Water)
- Uses energy from the sun to heat water.
- Can provide 1/3 of hot water needs.
- Water used for washing etc. not heating.
- Can be used to heat swimming pools.
- Cuts CO2 emissions by around 325kg.
How does a Solar Thermal system work?
Solar Thermal technology collects heat from the sun and uses it to heat water.
Solar Hot Water panels can either consist of flat plates or evacuated tubes. The panels heat a fluid (typically Glycol) that is then pumped to a special 'twin coil' cylinder.
The heated fluid heats the household water within this cylinder to up to 60 degrees where it is stored until needed.
Will a Solar Thermal System heat my home?
Residential Solar Thermal systems are designed to heat water for washing, bathing, etc.
Theoretically, the technology could be used to heat water for central heating. However, it would require a much bigger investment and more space to install a system with enough capacity to heat your home.
A Solar Thermal heating system would also be most effective in the Summer months, when you least need your central heating.
How much will a Solar Thermal system save me?
A typical residential Solar Thermal system, on a property with 3 to 5 occupants, will cut the water heating bill by around £55 to £85 per year.
From Summer 2013, residential systems will also receive payments for every unit of heat they generate under the UK government’s Renewable Heat Incentive (RHI).
The RHI means that households will receive around £250 per year, which when added to the fuel savings represents a Return on Investment of between 7 and 8%.
Are there any Grants available?
A Grant of £300 is available for domestic customers now. This is known as the Renewable Heat Premium Payment which is intended to bridge the gap until the full Renewable Heat Incentive scheme is launched in Summer 2013.
What is the Renewable Heat Incentive?
The Renewable Heat Incentive (RHI) is designed to encourage more use of Renewable Heat in the UK. Residential properties with Solar Thermal Panels will earn payments for every unit of heat generated from Summer 2013.
RHI Payments come directly from the UK Government and are likely to be 18p per kW of heat generated for domestic properties.
How do I know if my property is suitable for Solar Thermal?
Solar Thermal panels can be installed on most properties, providing there is sufficient un-shaded roof space facing West, South West, South or South East.
You should own the property and if it is a listed building or in a conservation area, for example, you must seek planning permission before proceeding any further.
Please use the checklist below to make sure you understand what is involved and see whether your property is likely to be suitable.
|To be used for hot water, not central heating.|
|Understand typical costs (£3,000 to £5,000 for domestic).|
|Understand the potential savings and benefits.|
|Property / land is owned by the applicant, not rented.|
|No restrictions e.g. listed building, conservation area.|
|3m2 to 4m2 of space available to locate panels.|
|Panels can face West, SW, South or SE.|
|Panels will not be shaded by buildings, trees, etc.|
|Have space for a larger or additional cylinder.|
|To be fitted by approved installers, not DIY.|
