Water way too hot after replacing thermostat

[Dave123]

Hoping you can help, our water was way too hot ( on nearly off setting) so our plumber replaced the thermostat on the boiler Glow Worm 45/60. Still having the same problem the bathroom is like a steamroom and it's impossible to get in the shower, boiler therm still set really low and all the water in the house and radiators is far too hot to stand.

Any ideas as to what else it could be gratefull recieved, thanks.

You need to get your plumber back IMO.
Hopefully he is GSR as it could be a gas issue.
