Would love to know if anybody's managed to resurrect an old
night-storage heater, circa 1986.
Mine died sometime during this summer. (Most unfortunate discovery at
the start of autumn.) There's very slight warmth in the external casing
in the area directly above where the thermostat is concealed. I've
opened the heater by taking off the front panel and had a look at the
thermostat. It seems a very simple affair and I suspect it's function
is to stop the current running into the heater when one of the narrow
metal plates in the thermostat gets so hot it bends away from a
neighbouring plate and therefore breaks the current. How soon or late
in the Economy 7 power period (1am - 7am?) the circuit is broken
depends, I think, on your turning the knob, which, I think, moves the
live metal plate away from or closer to the neighbouring plate.
I've tinkered with the plates, bending the metal etc., but it's made no
Is it possible to replace these thermostats?
Is it likely that the fault is elsewhere inside the heater? Does the
element in a night-storage heater easily break? (I'm not sure if they
are strong bars or delicate thin wires.)
Any help or comments would be most appreciated.
The make is Dimplex, if that helps.
