a 240 volt thermostat (or any 240 volt switch) is generally a 2-pole switch which means it breaks both wires going to the load You can use it for 120 volt loads by using one of the two poles for the "hotleg" wire and just splice through the neutral wire this is a 2-pole switch (the two blades move as one handle)
line___.__ \___._ load
line___.__ \___._ load The second pole goes unused and gives you a spare for the future

∙ 14y agoAssuming that you are talking 3 - 120V circuits of a single phase system such as a residential 240/120V system then the answer is a definite NO! The phase angle relationship is not the same nor is the Line vs Phase voltage. This could cause a fire and/or shock hazard.

It would be possible to run two heaters in series on double the voltage provided that they were identical and were both properly earthed.

Central Heating stopped working, themostat screen not working after changing battery now heat does not come on, fan works, still have hot water and gas dryer still works Do I need to replace themostat device?
Yes, If the thermostat isn't working, It cant tell the heat to come on. Thermostat is the brain of a heating & cooling system. Most likely the thermostat itself has worn out and does need to be replaced. You can get another digital one or you can change to an older style if you so desire.
How is the gas thermostat different from the thermostat in iron?
A thermostat on the wall measures air temperature to control a gas or electric heating (or air conditioning) system.A thermostat in a clothes iron measures the temperature of the metal ironing plate to control the electrical heating element in the clothes iron.

How do you fix a mira sport electric shower if the overheat protection thermostat has tripped?
First you must check why the overheat (one shot) thermostat has operated Is yours a hard water area ? If so the heater tank and heating element could be scaled up. This will severely limit the transfer of heat into the flowing water and cause an overheat of the heating element. The overheat will open the one shot thermostat. Check the heater tank and if not scaled fit a new one shot thermostat. Obtainable from Mira as a spare part. If the heater tank is heavily scaled I also advise to fit a new heater tank
