Immersion heater repair across Epsom
We serve Epsom from our base in Banstead.
What happens on the day
No heater on the cylinder means the booking stops at that finding. When a heater is present, work stays with whichever has failed among the heating element, the temperature control, the isolator and the feed. Water comes out of the cylinder only if the heating element must leave it. Afterwards the cylinder is warmed and we stay until the control stops the heat. Leaks and a gas combi stay outside. An original fuse board behind pebbledash is not swapped for this trouble.
- A heater has to be there alreadyThe heater has to be mounted on that cylinder. A house with none is told so, and a new cylinder is not put in its place.
- Identify the part, then fit itElement, thermostat, isolator or feed: the one that failed is identified first. Draining happens only for the element or its seal.
- Watch it heatThe cylinder is warmed and we stay until the control stops the heat. A fuse board swap is not opened to chase the same trouble.

What if the cylinder has no immersion?
Then the booking ends with that finding. A new cylinder is not fitted instead, and that is said at the cupboard.
Which parts can be changed?
Whichever has failed among the heating element, the temperature control, the isolator and the feed, on the heater already mounted. That part is identified out loud before the new part goes on.
When do you drain the cylinder?
Only when the heating element must leave the water. Changing the temperature control or the isolator, with the water staying in, leaves the cylinder full.
How do you know it worked?
The cylinder is warmed and we stay until the control stops the heat. A heater that stays cold is not treated as finished.
Are leaks in the figure?
No. Leaks, valves and a gas combi sit outside the booking. Work stays on the immersion already mounted.
