Do I need a room thermostat for my oil boiler?

A room thermostat can help stop your home getting warmer than it needs to be as it will turn the heating on only when required until the room reaches the desired temperature you have set on the thermostat, switching it off until the room temperature drops to a point where the heating needs to come back on again. It is therefore recommended that you have a least one room thermostat fitted in your home alongside your Grant oil boiler. To allow greater temperature control in different areas, it can be beneficial to install more than one room thermostat in your home, for example one downstairs and one upstairs giving independent control of each heating zone.

If your boiler was installed after 15th June 2022, thermostatic room controls (such as a room thermostat and TRVs) should have been fitted in each of your rooms as this is a requirement of Part L Building Regulations.

A room thermostat will monitor the temperature of the area in which it is located, feeding this information into the heating system so that your boiler fires up if a room gets too cold or pauses the boiler’s fire-up process when a room or area is up to the desired temperature. They can help you to regulate the temperature in your home more accurately, ensuring the heating only comes on until your desired room temperatures have been reached. If you want to optimise your heating system’s performance and you do not currently have room thermostats fitted, investing in one or more room thermostats could be beneficial so speak to your heating engineer to discuss this further.

What temperature should a room thermostat be set at?

The temperature you set your room thermostat(s) to will be determined by several factors such as the type of room in which the thermostat is fitted and how warn you want a room to be. Typically, a room thermostat located downstairs should be set around 18°C-20°C and one fitted upstairs will be set to around 20°C-22°C. If you try turning your room thermostat down a degree or two, you could also save even more on your fuel bills.

What temperature should I set my thermostat in winter?

You do not need to turn your thermostat up when it is colder outside as the house will heat up to the set temperature whatever the weather. On colder days, it may take a little longer for your desired temperatures to be reached, so you might want to set your heating to come on earlier in the day in the winter. To adjust the time at which your heating comes on and goes off, view your heating schedule on your controls.
