Unvented cylinder

We are G3 certified and therefore all work we carry out is in compliance with industry standard requirements. Our services include repairs , servicing and installations on most makes and models. Knowing your type of system – Unvented cylinders can be either indirect or direct. You can determine this on whether or not you have an additional heat source indirectly heating the cylinder store of hot water. Or directly heated via immersion. Direct types can also be setup up on an ‘economy 7’ tariff for ‘Off Peak’ and ‘On Peak’ rates with your energy supplier. This can be heated via ‘air source heat’, gas / oil and electrical boilers in combination with renewable energy appliances and systems. In most existing residential homes natural gas is the most commonly used.
