There are so many controls that come with your heating system that it can be difficult to know what each does and what temperature your appliance should be set to. You might have a room thermostat, radiator controls, a boiler thermostat and a water cylinder thermostat.
So, what temperature should each of these be set to in order to heat your home in the most efficient way? In this article, we explain what each of your heating system controls do and what temperature they should be set at in order to keep your home cosy this winter.
Most modern boilers will have a digital dial that allows you to set the output temperature. Please note that for best efficiency with Viessmann boilers we would recommend weather compensation , this automatically adjusts the heating boiler flow temperature to the optimum temperature to external weather conditions. The higher this temperature is set, the quicker your boiler will be able to heat your home. If you have a conventional boiler system, your water cylinder will have its own thermostat.
This is usually fitted on the side of the tank. You should utilise all of the controls in your heating system to ensure that your home is being heated in an efficient way.
This is the most comfortable and healthy temperature for your home. A programmable room thermostat should allow you to set separate temperatures for different rooms at varying times of the day.
Another way to control your heating is via thermostatic radiator valves TRVs. A TRV will control the flow of water that passes through the radiator to change the amount of heat that it gives off.
If you follow our recommendations above, your boiler should continue to heat your home efficiently. When the weather starts to cool off, it can be tempting to turn up the TRVs, the room thermostat or even the boiler thermostat. However, in doing so, you could waste a lot of energy and your heating bills may increase. If your heating is on but you still feel cold, you should grab a pair of woolly socks to wear on your feet and an extra jumper.
Blankets are a good idea for a cosy night in. Choosing to do this instead of increasing your heating system temperature is better for the environment, too.
A condensing boiler is one of the most efficient types of boiler. This is because it is able to recover virtually all the heat from the flue gases and use this to heat your home.
For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature. The exact temperature setting for a combi boiler is not set in stone, though there are some generally accepted guidelines for efficient operation and heating performance. For a modern combi boiler, the radiator heating temperature should be set at or around 75 degrees celsius for the best efficiency and performance.
As an additional note, this temperature setting refers to the temperature of the water inside the radiator while heating your home; if you have young children or anyone that may be sensitive to higher temperatures in your home, we recommend reducing the boiler temperature to the lower 65 degrees celsius at all times, or to use a radiator guard.
Meanwhile, we recommend the water heating temperature to be set at around 60 degrees celsius. Setting this any higher can increase the risk of scaling within your system, so is ill advised.
This setting should again provide an ideal balance of heating performance and efficiency for the majority of homes.. Adjusting the radiator and water temperature on a modern Vaillant combi boiler is quick and simple.
Our modern boiler systems come equipped with a user control panel and LCD screen to facilitate adjusting the temperature, where individual settings can be input for your water and radiator temperature.
The actual process may vary depending on your specific model, so we recommend referring to your user manual for specific guidance. With that said, many of our systems will have a button for the radiator temperature and hot water temperature.
It is never a good idea to turn off radiators in individual rooms. If a room of your home is not in regular use, turn the thermostatic valve down as low as possible to prevent problems with mould and damp from occurring.
