Common questions
What is an unvented cylinder?
It stores hot water at mains pressure, so you get strong flow at every tap and shower without a loft tank or pump.
Can I fit one in my garage or utility room?
Often yes. We have installed cylinders in garages, cupboards and plant rooms, with insulated pipework and the right controls.
How long will it take?
A cylinder replacement is commonly completed in a day or two. We will agree timings when we quote.
Will it work with my boiler?
Most system boilers and many combi installations can be paired with an unvented cylinder. We will check your setup.
