Unvented Hot Water Systems

Unvented water heaters or hot water tanks (also known as cylinders) should only ever be worked on by someone who is properly qualified, familiar and experienced in the type of system they are working on.

If not repaired, maintained or installed properly they can become a ticking time bomb, very unsafe and at risk of exploding.

If you have no hot water,  a discharge from a safety valve or a leak give us a call. We can usually attend the same day and aim to arrive within the hour, if you’re in Leeds or not too far.

You can also have us upgrade your old cylinders to unvented hot water cylinders and install hot water heaters from 8 litres to 300 litres.

We never charge a call out fee, even for emergencies, you shall only pay for the time we are there and any parts required. We also offer OAP discounts.

We service and repair unvented hot water heaters such as Albion, Ariston, Heatrae Sadia, Main, RM cylinders, Tempest, Megaflo, OSO, Gledhill,Tribune, Kingspan and many other brands. We also repair thermal stores such as IMI Range Flowmax and replace timers such as the Hortsmann economy 7

Unvented Cylinder and Water Heater Repairs
