Set points on thermostats.

Long gone are the days when your central heating system was either on or off.

When they were on they were controlled by a single thermostat that you had to either turn up if you were too cold, or down of you were too hot.

The modern thermostat controllers are now on all the time and you set the temperature at the level you want at a certain time of the day, so for example, when you get up the set point is 21 degrees C, but when you go to work the set point is set at 14 degrees C, when you come home from work the set point may be 18C increasing to 21C when it is time to sit down to watch TV, and when it is bed time it is reduced to 14C.

Most well insulated houses probably do not get below 14 degrees and so the boiler/heating system never comes on, but if it does for some reason then the boiler comes on for a short period to maintain that temperature. This is actually more efficient than having your heating system have to heat the house from a much lower starting point.

Let's say the house does get to 10C, and the system didn't come on until half an hour before you wanted it to get to 21C, it would have to work an awful lot harder and probably wouldn't make it in time whereas if it has been set at 14C, then it doesn't have to work any where near as hard to get up to 21C.

There are many thermostat/controllers on the market and most of them work to this principle. We recommend a few which we sell on our website www.multiheat-infrared-heating.co.uk
