This is a mains-fed hot water system that needs servicing annually. There are safety components that need to be checked, and if you don't service them, you may end up with a very dangerous installation. So, please get in touch straight away if your unvented cylinder is in need of a service.
Customers just need to give us a call. If it is a repair or call out, we will provide the customer with any charges over the phone. If it is an installation or replacement, we will go out and visit the customer and provide a free estimate for the service.
