Why Choose Solar Thermal

Use The Energy From The Sun To Heat Your Water.

Free Hot Water Throughout The Year

Solar water heating systems can help you achieve savings on your energy bills.  Based on the results of a recent field trial*, typical savings from a well-installed and properly used system are £60 per year when replacing gas heating and £70 per year when replacing an electric immersion heating.

Although the system works 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.

energy consumption and cut costs.”

Reduced Carbon Footprint

A typical Solar water system will save 275kg of CO2 per year compared to water heated by gas and 490kg compared to water heated by electricity.

Earn As You Save

You may also be able to receive payments for the heat you generate from a solar water heating system through the government’s Renewable Heat Incentive:

2 person household = £190 RHI Income per year

3 person household = £260 RHI Income per year

4 person household = £330 RHI Income per year

5 person household = £425 RHI Income per year

6 person household = £460 RHI Income per year

You may also be able to get help with installation costs through the Renewable Heat Premium Payment scheme.

Is My Property Suitable


Is Your Home Suited To Solar Thermal Heating?

Most homes 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 home could be suitable for a solar thermal installation.

“Most roofs are more than capable
of supporting a solar thermal system”

Does your roof face the sun

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.

Does your roof have the right pitch

Is The Chosen Area Shaded?

Most homes in the UK tend to have a roof pitch of around 30 – 50 degrees. If other buildings, trees or chimneystacks 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 home 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 home’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

“Panels collect heat from the sun,
which heats water in a cylinder.”

  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.


Frequently Asked Questions


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.

“Solar thermal installation is fast, with
minimum disruption to your home.”

 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.
