A new cylinder is a separate job. TMB Electrics, based in Banstead, repairs immersion heaters in Ewell at the cylinder that is there. KT19 semis are tested at the element and the stat. A new cylinder is not assumed. ## Ewell immersion price Immersion work in Ewell is priced for testing and, where needed, replacing the element or the stat on the cylinder already there. A KT19 cupboard with a failed tank is a different figure. - Immersion heater repair: from £80 an hour; from £80 an hour - A new cylinder is not included in an element or stat repair. - Plumbing alterations around the tank are outside this figure. - Parts are named after the tests, not guessed before the cover comes off. ## Immersion heater repair across Ewell We serve Ewell from our base in Banstead. - High Street - Church Street - Kingston Road - London Road - West Street - Chessington Road - Ewell Court - Stoneleigh ## What happens on the day The cylinder stays. Supply to the immersion is isolated, then the element and the thermostat are tested. In a KT17 or KT19 semi the cupboard and the board that feeds the heater are both identified, because those houses may have more than one board. If the cylinder itself is finished, that replacement is a different job. The heater is left to heat only after the tests pass. ### Find the feed The board and the switch that feed the immersion are identified. A second board in a KT19 semi is not ignored if that is the one feeding the cupboard. ### Test element and stat The element and the thermostat are tested with the supply isolated. A failed element is replaced when that part is the fault and the quote covers the part. The cylinder body is not swapped on a guess. ### Leave it heating After the tests pass, the heater is switched back and left to heat. You are told what was changed. A new cylinder, if the tank has failed, is described before anyone drains it. ## Ewell immersion questions ### Do you replace the cylinder as part of an element change? No. The element or the stat is changed when that is the fault. A failed tank is described as its own job before the cylinder comes out. ### Which board feeds a KT19 immersion? Whichever one the tests show. These semis may have a second or third board, and the cupboard switch is traced back to the right one. ### Will you drain the tank on the first visit? Only if the element has to come out and that repair is already accepted. A tank replacement is not started on a guess. ### Is the thermostat included if it has failed? When the tests show it has failed and the part is covered, yes. If the quote was diagnosis only, the part is named before it is fitted. ### What about a High Street house with a protected cupboard? The heater is worked on at the cylinder. Finishes around the cupboard that must stay are left. We do not alter the cupboard joinery. ## Other services in Ewell - [Electrician in Ewell](https://www.tmbelectrics.co.uk/electrician-ewell): Ewell electrician for carefully scoped domestic work, with electrical condition and heritage constraints treated separately. - [Immersion heater repair (all areas)](https://www.tmbelectrics.co.uk/services/immersion-heater-hot-water-repair): TMB Electrics immersion heater repair in Banstead from £80 an hour.
