Boiler repair - new thermostat and rewiring to the correct setting
£250
Battersea, Greater London, SW11
4th Jun 2025
Santon Premier Plus boiler repair needed. Another air tasker came to "fix it". My original problem was the hot water wasn't heating as normal, only the emersion heater was working. The air tasker sent some one to Replace burnt out thermastat / heating element. . But for some reason he rewired the economy 7 setting for the boiler and switched the emersion worrying so the boiler was on 24/7 and the water was scolding hot (55c). The boiler broke again after a few days. I assume the thermostat / heading element broke again. Need someone to fix the problem caused acne fix the thermostat again and the temperature issues.
