Just installed new bathroom. Pump serving showers and bath taps but keeps cutting out saying water too hot or aerated. Fitted new thermostat to hot water cylinder, and turned down heat control on boiler, but water still very hot. Help!

don't have electric heater, have turned thermostat down to 50 (says 60 is normal). Pump doesn't cut off every time, so runs normally sometimes, but then will cut out. Water very hot when you put hand under tap. Thanks for your help.

FAO Plumber. Thanks for that. As we have gravity fed system the bathroom installer said we needed "whole house" pump, as I have shower in bathroom, shower in en suite, and he has put the bath taps on pump too. Only the basin taps are not and that water flow from those is quite slow, which is OK as only basin. The thermostat was bought new yesterday, and wiring seemed quite simple????

Check to ensure that the thermostat is working, I know you said you'd just fitted it yesterday, but it could be faulty, that would be the only reason for the water to overheat. You could start from scratch and turn off the hot water heating until the water runs cool through usage, ten turn the water heating back on with the Thermostat down to 45 degrees and review the results

A simple job, but only if you are happy and competent working with electricity. All DIY shops can sell you a strap on thermostat. The thermostat must be fitted such that the back is touching the metal of the hot water cylinder. If you have a pre-lagged cylinder, you will have to cut a hole in the lagging through to the metal. The thermostat is then placed in the hole and the strap fitted around to hold it in place. The difficult bit is connecting it to the boiler controls. If you have no cylinder thermostat at present, it is likely that you have a pumped circuit out to your radiators and a seperate pair of pipes to your cylinder that are not on the pumped circuit (a gravity feed circuit). That means that your hot water will be at the temperature you have set your boiler. No problem in the summer as you can set the boiler low. In the winter you set the boiler higher to get the house warm and then the water at the taps is too hot. In this pipe circuit to the cylinder you will have to cut a new on/off control valve. You will then have to put interconnecting wires between the new thermostat, the new valve and the boiler controls. If the system is old, (or newish and installed on the cheap) you may not even have a proper system control, in which case you will need one. That means a lot more wiring. I suggest you talk to a few friends and you may find one who help you out. Remember, behind those simple on/off switches around your house is a power that can easily kill you. What might be simple and logical to many is death to others. If this sort of thing is new to you, get a professional to do it. It may cost you more money, but consider the devastation to others if you kill yourself.

Check the wiring connections on you thermostat. If that is okay then you have a faulty stat. Ps Why have you got a pump for shower and bath taps?

You've got the mother of all airlocks and have to bleed the system or you need to crank down the thermostat with the little screw on the top (visible when you remove the black plastic cover).

If you've got a boiler and electric water heater in the tank, try turning off the electric one, as you don't need them both running.
