Combi Boiler Solar System

An unvented pressurized cylinder will be required and can be located anywhere to suit your requirements, this is linked into your existing hot water supply via a 3-way motorized valve to enable you to draw off hot water from the unvented cylinder when the required temperature is reached, yet switch over to your existing means of heating when the store is not at the required temperature.

Here’s how it works and how it can save energy and reduce your heating bill.

1. The stored volume of hot water is only heated by energy from the solar panel – so there is never any gas used to heat the water stored in the cylinder.
2. If the Combi boiler does fire, then the water being fed into it will be pre heated, so the boiler will not have to fire on full load therefore using less gas.
3. This system is revolutionary because it is used in conjunction with a Combi boiler and therefore hot water is not stored unnecessarily but always available on demand.

Please note:-

Unvented pressurized water cylinders MUST be installed by a qualified engineer who holds what is informally known as a “G3″ card. Part G3 of the building regs covers the installation of unvented hot water vessels. Our installers hold this qualification.

Key safety features:

• Safety by professional design and installation; the design and sizing of your system are vital to insure safe operation.
• The evacuated tubes are inherently safe as the solar energy stops getting collected when the tube temperature reaches 85°. This is achieved by using state-of-the-art self-limiting intelligent metal technology.
• Modern self-modulating electronic controller using Plug and Play technology.
• 3 bar Pressure Relief Valve.
• 18-24 litre Expansion Vessel — This vessel is used to accommodate the increased water volume when the system is working.
• All safety components have been tried and tested by the solar industry for over 25 years and have a proven tack record for their performance and reliability.
