What is a thermostat?
The Room Thermostat is a common fixture in most homes, helping to maintain an even temperature in the house all year round. In the winter, room thermostats (sometimes referred to as roomstats) prevent rooms from overheating. In the summer months, they ensure the heating system does not fire up unless the temperature of the house falls below a preset level.
How do thermostats work?
A thermostat is normally a control unit for a central heating boiler, but these days it can also control electric heating such as infrared panels. You choose the temperature that you would like the house to be at via a dial or a digital display on the thermostat. The thermostat then monitors the ambient temperature of the air and instructs the boiler/heating system to turn on or off accordingly.
If the temperature of the ambient air is lower than the requested temperature set on the thermostat, it will fire a message to the boiler to fire up and send hot water to the radiators to heat the house.
If the air temperature is too high, the Underfloor Heating Thermostat will send a message to the boiler to switch off, which obviously should result in the home cooling down.
Using a thermostat will therefore ensure that the house stays at a regular temperature and rooms don’t overheat. The thermostat will ensure that the boiler keeps a constant temperature in the house, which results in an efficient heating system that will save you money on your gas bills.
How much can a room thermostat save?
A correctly-installed thermostat can save you £100s per year, however you have to know how to get the best out of it. For example, a pre-installed room thermostat can save about £65 for every degree centigrade you turn it down. Therefore if you normally have your home at 230C and then decide to turn the Gas Boiler Heating Thermostat down to 210C, you should see energy savings of well over £100.
We have written a blog you can read here on the optimal indoor temperature, which discusses some of the common queries people have when it comes to setting their thermostat.
Thermostats do not speed up the rate of heating
One common misconception of thermostats is that if you turn up the dial of the thermostat, the room will heat up quicker. The rate at which a room heats up is dependent on the boiler, the size of the room, the size of the radiator and finally, how well-insulated the room is.
Thermostats and draughts
Roomstats are sensitive little things; if they are hit by prolonged cold draughts they will instruct the boiler to fire up. This means that they have to be positioned very carefully in the house.
For example, we have seen thermostats installed in clients’ hallways just by the draughty front door. This means that they will normally be recording a lower temperature than the actual ambient temperature of the house and will instruct the boiler to fire up, using more gas.
