Solar Thermal FAQs

Q:  What are Solar Thermal panels?

A: Solar Thermal panels heat water using the sun's energy.  This water is pumped into a hot water cylinder for you to use in your property. 

Q: Will Solar Thermal provide all my hot water?

A: Solar Thermal will typically provide 50% of your annual hot water requirements.  In the summer it may be able to produce all the hot water you need.  Solar Thermal systems are typically paired with your existing boiler, which will provide the rest of your hot water. 

Q: Will my Solar Thermal system require any maintenance? 

A: When you get your boiler serviced, you could get the engineer to look at your Solar Thermal system.  It may require a check-up every few years to ensure that it is working efficiently. If you notice any issues with the system, you should get a qualified plumber to check it out. 

Q: Can you install a Solar Thermal system on any roof?

A: We would suggest an installation on a South-facing roof to get the most hot water.  The panels can be installed onto any flat or pitched roof with tiles, slates, metal sheeting or felt.  We will have to check that the roof is strong enough to take the additional load of the solar thermal panels. 

Q: What are the components of a Solar Thermal system?

A: A Solar Thermal system consists of one or more roof-mounted panels, a solar hot water storage tank, a pump, and a system controller. The solar storage tank is larger than a conventional hot water tank, to enable you to store your solar hot water for cloudy days. 

Q: I have a combi boiler, can I still get a Solar Thermal system?

A: Solar Thermal does not work as well with a combi boiler.  You will have to install a hot water tank, and this may not be compatible with all combi boiler models.  Get in touch with us to see whether your combi boiler system can be adapted for Solar Thermal. 

Q: What is the expected lifetime of a Solar Thermal system?

A: You can expect the panels to last for between 20-40 years.  The other components of the system may need replacing within this time-frame.
