Night storage heaters .................? I have brought a house to be exact about ten years hoary...

I have brought a house to be exact about ten years hoary but alas 2 out of the four storage heaters work. I know hoe to set them and how they are SUPPOSED to work but for some reason the other two cry off to work , they were working fine. i own taken the cover off etc to try and find a reset switch but can't find one.CB

Answers:    On a dimplex storage boiler the reset button is inside top right hand side of the space heater press it till you hear a click ( turn off boiler first )

Did you check the circuit breaker? Find the right breaker and turn it off later on. Sometimes it is difficult to tell if it have tripped, just by looking at it.
