Solar Thermal

Reduce Your Water Heating Costs – Reduce Your Carbon Footprint
Solar thermal systems work alongside existing heating systems and are particularly well suited to integration with heat pumps.
Although solar thermal panels work all year round, heating around 80-90% of your hot water in summer, a conventional boiler or immersion heater can be required to make the water hotter during the winter months.
In commercial premises a typical Solar water system may save up to 350kg of CO2 per year compared to water heated by gas or electricity.
Earn As You Save
You may be able to receive payments for the heat you generate from a solar water heating system through the government’s Renewable Heat Incentive.

Is Your Property Suited To Solar Thermal Heating?
The first important thing to remember is that solar thermal systems are site specific. They are only suitable where there is a heat or hot water demand.
Unlike solar PV, if there is no on-site demand then there is nowhere for the energy to go and you will not get any benefit from the system. The bigger the demand, the bigger the potential benefits from a solar thermal system.
Phase one of the RHI (for non-domestic properties) requires the use of heat metering to determine the amount of energy units generated and where the energy is used. Ensuring systems are designed and working efficiently will be key to ensuring a good return on investment and a long lifespan.
By  getting the site and the design of a system correct the potential returns can be very attractive.
Most properties are suitable for the installation of a solar thermal system. As our systems cover a wide range of roof types and property types, we are very likely to find a solution that is right for you.
If you answer yes to the following questions your property could be suitable for a solar thermal installation.
Does Your Roof Face the Sun?
It is best if your roof is South facing, but East and West facing properties can also benefit from our split systems which makes the most of the sun from either direction. You will need around five square meters of roof space.
Is the Chosen Area Shaded?
If other buildings, trees or chimney stacks cast shadows on your roof, it may not be appropriate to install solar panels on your roof. However, solar PV panels can be installed directly on property walls, so your property may still be suitable for a solar thermal installation.
Is The Roof Structurally Sound?
During our site survey, we will inspect your roof to ensure it is structurally capable of holding the load of the solar panels safely and securely. Most roofs have more than ample capability.
Are There Any Obstructions?
If you have roof windows, vents, or chimneys in the area that your solar panels need fitting, these may need relocating if possible, otherwise they may prevent the install from going ahead.
Is Your Current Boiler Compatible With Solar Water Heating?
Most conventional boiler and hot water cylinder systems are compatible with solar water heating. However, if you have a combination boiler (combi) and you currently don’t have a hot water tank a solar hot water system may not be compatible.
You will need to replace your existing cylinder or add a dedicated cylinder with a solar heating coil.
How Does Solar Thermal Work?
Solar water heating systems, also called solar thermal systems, use the power of the sun to heat your property’s water.
Solar water heating systems use solar panels fitted to your roof to collect heat from the sun to heat up water stored in a hot water cylinder. This is done by passing a fluid through the panels and pipework, which heats up and is then pumped through a coil within your water cylinder, which heats water in the cylinder to the desired temperature
Solar heating systems tend to work much better in summer months, heating around 80 – 90% of your hot water, but can still provide significant benefits during winter months too. The solar fluid never touches the water itself, but merely heats the cylinder to the desired temperature through heat transfer.
Is There Enough Sun In The UK For Solar Panels To Work?
Believe it or not there is. The UK actually receives the same amount of sunlight as parts of France and Spain. Solar panels are powered by light – not heat or direct sunlight. So even when it is raining solar PV panels are still absorbing more than enough energy.
Are There Different Types Of Solar Thermal Panels?
There are two types of panels that can be used:
Flat-plate collectors represent very good value for money, and last for many years with minimal maintenance. These systems are usually large glazed panels, which sit flat to the roof. Their format better lends themselves to new builds and buildings requiring a complete re-roof.
Evacuated-tube collectors are a great solution if you only have a small amount of roof space available, as they are known to be more efficient than flat-plate collectors. These systems are also very flexible and versatile, as they can be fitted in any orientation to a pitched or flat roof, as well as being fixed directly onto walls should space be at a premium.
Do You Need Planning Permission For Solar Panels?
Planning permission regulations were altered in 2008 to make the installation of renewable technologies a more straightforward process. This has meant that most commercial solar panel installations in the UK do not require planning permission. We will of course advise on your particular circumstances as part of our initial site survey.
How Long Does Installation Take?
The average solar thermal installation only takes around 1- 2  days.
How Do I Claim the Renewable Heat Incentive?
Once you have installed your Solar Thermal system Energy Gain UK will provide you with a certificate to confirm your installation meets with the Micro generation Certification Scheme (MCS) standards. We will then assist you through the process to complete your claim.
