Solar Water Heating

Just think how hot the inside of your car gets when it’s left outside on a bright summer’s day.  Our Solar Water panels react in just the same way.   They capture heat from the sun and transfer it to your domestic hot water tank, giving a FREE supply of hot water.

Hot water on, central heating off

Most home owners would like to keep their oil or gas boiler off for about eight months of the year.  So it’s frustrating and expensive to have to turn it on, just to heat some water for domestic use.  Solar Water Heating from Solmatix generates a steady supply of piping hot water, just when you need it, without having to run your central heating and incurring huge oil or gas bills.

In fact, Solar Water Heating will typically save you about one third of your oil or gas bill, which for most households means an extra £500 in your pocket, year after year.

Not only that, domestic customers can benefit from the NI Renewable Heat Incentive (NI RHI) which provides a £320 one-off grant followed by annual payments for 7 years!

How Solar Water Heating works

Solar water panels on your roof contain an antifreeze liquid which heats up rapidly when exposed to the sun’s rays.  When heat has been captured, this liquid circulates to your domestic hot water tank, keeping the water at a steady 55°C to 60°C.  This makes it ideal for baths, showers and domestic cleaning, and reduces or eliminates the need for oil or gas heating in the summer time. And remember – typically we shower or bath in water at 36°C.

Ideally, Solar panels are sited due south to capture the most energy from the sun, but Solmatix can configure your panels to suit most locations.

Some description

Solar Water Heating doesn’t just mean lower oil or gas bills and a steady supply of piping hot water.  It also means you get immediate and long-term grant income.  

Under the NI Renewable Heat Incentive (NI RHI), the government is encouraging home owners to install renewable energy systems by offering substantial grants.  So when you install Solar Water Heating from Solmatix, you will receive a one-off payment of £320 towards your costs.  

The grant that keeps on giving

And there’s more.  Under the NI RHI scheme, your Solar Water Heating system gives you an additional income of £100 - £200 annually for seven years.  This means an average customer will benefit from £1720 in total grant aid! And we do all the paperwork, so you have none of the hassle.

Solmatix can install two types of solar water panels for your home:

Flat Plate

Most of our customers opt for flat plate panels.  As well as being robust and durable, they can also be integrated into your roof.


Tubes are marginally more efficient than flat plates but they are more visually intrusive and fragile.


Whichever system you choose to install, the antifreeze liquid in your Solar Water Heating system will need replaced every two years or so.  Solmatix engineers can complete this task quickly and cleanly on your behalf. This will ensure a steady flow of hot water for baths, showers and domestic cleaning, with much less need for oil or gas heating.


The length of warranty depends on panel type.  Flat plate comes with 10 years cover whereas evacuated tubes are 20 years.
