Solar Install and Service


DDV recommends that your solar system is serviced annually. Over time the glycol antfreeze starts to break down in the system causing pressure and efficiency losses. If the system stagnates at any time which is common and fluid is lost from the system, the system will not work and the excess heat through conduction on the pipework can burn out the circulation pump and damage seals and gaskets. Expansion vessels also need to be checked and set to correct pressure along with controller settings readjusted.


Therefore it is important to gain optimum performance from your solar system that it is serviced regularly. This will ensure that in the cold winter months when it costs most to heat hot water that the maximum solar gain is achieved. We services all makes and models including Joule and Kingspan.
