Heating a Room Versus the Entire Home

People often wonder if it is more efficient to heat the entire house or just a single room. The answer varies depending on the size of the room, how long the family members stay in there, and what type of heating system they have. Read the discussion below about heating a single room versus the entire home, depending on the method of heating one has.

Modern Boiler

A modern boiler and proper insulation should suffice to make it more efficient to heat the entire home rather than one room. After all, an updated one should have a balanced flue, heat exchangers, and condensing technologies. The modern boiler’s specifications maximize the heating efficiency, which puts it at the top when it comes to providing warmth to the home.

If your boiler is out-of-date, it is ideal that you either switch to a modern boiler or make sure that you maintain it. Only choose certified technicians to work for you, it will guarantee that you will get the most out of what you pay. For more ideas about boilers, you can check online.

Modern Heating Radiators

Modern central heating radiators should have a TRV or thermostatic radiator valves. These act as a thermostat that maintains varying temperatures in different rooms of a house. As such, you can heat up only one room, while keeping the others at a sufficient temperature.

Heating Radiators Without Temperature Controls

The lack of a temperature control should not prevent you from maintaining sufficient heat in the home. You can opt for either an electric heater or a gas heater and install it in the room you spend the most time. Meanwhile, your central heating radiator can maintain a reasonable temperature for the entire home.

Storage Heaters

Storage heaters utilize off-peak electricity, so you have to top it up with peak rate electricity for the extra warmth. You can take advantage of them by allowing them to heat small rooms. Of course, you should minimize transfer of heat, so always close the door of the room.

Gas Fire

Unlike modern boilers which have 90% heating efficiency, a gas fire is only at a half to 60% efficiency. Also, gas fires require fresh air as an oxygen source for the combustion process, which means that ventilation is needed, and that leads to loss of warmth due to the circulation. Overall, you would only want to utilize gas fire for heating if the room’s size is only up to one-third of your home’s.


Depending on your room’s size and the type of heating, it may be best to either heat a single room or the entire home. If you have a modern boiler, you can heat the whole house since the heating is efficient. As for heating radiators with TRVs, you can heat up a single room, while maintaining the temperature of the others. If your radiators lack a TRV, just rely on a heater for the room you stay in the most. As for storage heaters and gas fire, the former does well for heating small rooms, and the latter is somewhat inefficient for heating.
