electric water boiler, the flat was built in the 80's and the water coming out of the shower is boiling.i cant turn it down, it goes from hot to boiling hot.if anyone can help i would be very happy.
it's just a dial with temperature on,if your temp is up and down there could be a fault
I'll try and guess what system you have - so bear with me. If it's an electric heated shower, Most likely it would be easier to replace the whole thing. If it is a Thermostatic shower using your stored water - then it should self-compensate depending on the dial setting. If it does not, the seals have probably gone in the unit. It could be repaired if you find the make and model, but may be easier-and cheaper to replace the whole unit. Phone around - especially the distributers to see if they supply parts. The more expencive the unit - the more likely replacement parts are stocked. If you have no luck, replacement of the whole unit seems likely. If your tap water is coming out over 60degrees C, then your boiler thermostat probably needs adjusting. Some don't like moving, and will fail rather than be adjusted - so replacement is usually better. Hot-tank electric immersion thermostats are usually under the heating element cap on the tank. MAKE SURE POWER IS OFF AT THE MAINS - DO NOT TAKE CHANCES. Use a power-checker device to make certain. Undo the main small screw on the heating element cover, and remove. Inside is the thermostat - the boxy thing with 2 wires into it, and usually a dial pointing to temperatures. If you can turn this adjustment down, then do. - and cover again - make sure wires are clear of all parts, and cover goes on easily. Try this for a few days. If still no good - power off, remove cover, this time - unscrew the 2 wires to the thermostat - and withdraw it from the little tube it sits in. It should be a brass rod about a foot long. Take this to a diy store for an exact match replacement. Set to 60, put in, wire up, cover, THEN power on again. That should do it. (unles you have 2 elements- and 2 thermostats - then you need to do both)
