Why does my heating come on when its switched off?
Why does my heating come on when its switched off?
A check valve is used to stop the natural convection from warming up your home when your heating is switched off. If the check valve is broken or blocked, heat will rise through your system causing your radiators to stay hot. Once again, contact a qualified professional to come and check what the problem is.
Why do my radiators get warm when the heating is off?
The diverter goes into a ‘mid position’, which allows the hot water to flow to both the water tank and the radiators. When a diverter fails or gets blocked with debris, hot water intended for the hot water circuit can get into the radiator circuit. Then the radiators will be hot even though the heat is turned off.
What happens if the thermostat is turned down but the heating is still on?
If the temperature drops below that it will still come on. This. If the heating on the boiler is set to ‘ON’, then if the thermostat is turned down to 15C, for example, the heating will still come on if the room temperature falls below 15C. We have a two level thermostat and that is how ours is designed to work.
What is the difference between a temperature switch and a thermostat?
A thermostat regulates a temperature of a gas or liquid between a low set point and a high set point ( the hysteresis). For heating in a house, factory, car or hot water heater, for example, the low set point switches on the heat source, and it continues to heat until the thermostat reaches the high set point switch.
When do you need to change the thermostat setting?
Instead, you should change your thermostat temperature setting whenever you leave your home for 8 hours or longer. After all, there’s no need to heat or cool your empty home to the same temperature as when you’re home, right?
What should I do if my thermostat wire is short?
Shorting the thermostat wires together is the same as a thermostat calling for the heating or cooling system to run. If you cannot find and fix the shorted thermostat wire fault (check first around the wall thermostat and around the primary controller at the other end of the same wires) you’ll need to re-wire the thermostat.
If the temperature drops below that it will still come on. This. If the heating on the boiler is set to ‘ON’, then if the thermostat is turned down to 15C, for example, the heating will still come on if the room temperature falls below 15C.

What to do when your thermostat says one temperature?
When your thermostat says one temperature and you know the room is another, it may be dirty, tilted on the wall, or located where it can’t get a proper reading. 1 Turn the power off to the heating system.
What to do when your heating system won’t turn off?
First Step: Change the thermostat setting up or down. If the heating system won’t turn OFF, that is if heat keeps being delivered even when you don’t want it, set the thermostat to its lowest temperature setting and wait three to five minutes. Or if your thermostat has a HEAT OFF COOL or FAN AUTO OFF control, set the control to OFF or COOL.
Why does the thermostat on my furnace need to be adjusted?
If your gas- or oil-burning furnace cycles on and off too frequently or there are major swings in room temperature before the furnace goes on, the thermostat may just need a simple adjustment. To adjust the thermostat: 1 Remove the thermostat’s cover.
