Cylinders

Andrew repairs and replaces hot water cylinders around Halesworth. If your boiler heats a tank in the airing cupboard and the hot water has gone lukewarm, runs out quickly or the cylinder is leaking, the fault may be in the cylinder itself or in the controls that feed it.

Common cylinder faults

Typical problems include a cylinder thermostat that no longer switches the boiler on, a zone valve that has stuck shut, a failed immersion heater element, a leaking joint on the cylinder pipework, and an old copper cylinder that has started to corrode or weep at the seams.

Repair or replace

Thermostats, valves and immersion elements can usually be changed on their own. A cylinder that is leaking from the body needs replacing, and that is a good time to look at whether a larger or better insulated cylinder, or a move to a combi through boiler replacement, would suit the household better.
