Solar PV systems use the suns heat to produce electricity, which is then used to provide heating in the home
Solar thermal systems use the suns heat to heat liquid within the system, converting this into usable heating in the home.
SOLAR HEATING v THE REST
How does Solar heating compare to other renewables
Why a solar thermal system from Regulus?
Solar Thermal systems are often referred to as 'wet solar' as they heat liquid within the system which then transfers the heat to a hot water tank.
Regulus are an established European manufacturer of Solar Thermal systems, proven in extreme conditions. Systems may achieve a large saving on energy costs and provide in excess of 25 years reliable service.
A solar thermal system is often combined with a heat pump or other energy source, together with a hot water 'heat store' or 'buffer tank' to provide reliable heating whatever the time of day or season of the year.
A solar thermal system contains several basic components: solar collectors (placed on a roof, on a wall or ground mounted), circulation pump and a hot water storage tank (or thermal store).
Solar collectors are manufactured in two designs:
1. Flat plate solar collectors (vertical or horizontal)
are the most popular collectors with an excellent value for money ratio.
2. Evacuated tube collectors
they are highly efficiency under a low angle of incidence of solar rays.
Frequently a solar thermal system is a component in a complex heating system based on a combination thermal store for both space heating and hot water heating. This thermal store can then be heated by other heat generators such as a heat pump or biomass boiler.

* PV systems convert energy from the Sun into electric energy.
* They can supply electricity for the house itself or to the national grid.
* Energy can be stored in a hot water (buffer) tank or, increasingly in home battery systems similar to those in an electric car.
* PV collector panels are now very efficient and as a result smaller for any given heat output.
* Maintenance is very low.

Air source heat pumps and ground source heat pumps extract heat from the air or ground. The air contains heat that can be used to heat a property even in temperatures below 0°C while underground temperatures sit at a constant 10-15°C.
Biomass boilers operate much like conventional boilers. They burn plant-based organics such as wood pellets, chips and logs. The heat produced when burning the material warms up the water is then used to provide central heating and domestic hot water. Some biomass boilers need to be fed the fuel manually while others do this automatically.
