What temperature should a condensing boiler be set at?
This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C. Do not set it lower than this as you could increase the risk of contracting Legionnaires’ disease.
Why do condensing boilers plume?
Because the flue gases leaving a condensing boiler are cool, they tend to produce a noticeable mist or plume of water vapour around the flue terminal itself (as they condense upon contact with the atmosphere), especially under cold conditions.
Do condensing boilers use more water?
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.
When to turn the thermostat up or down on your boiler?
When the weather is cold you need your boiler thermostat to be set to a high level to make sure your house can get warm enough. If the weather is milder, you could turn the boiler thermostat down and still be warm enough. This will make the system more efficient, especially if you have a condensing boiler.
When does a boiler go into condensing mode?
Condensing boilers need to operate at lower temperatures to non-condensing boilers in order for the heat to turn back into water before it leaves the flue via the second heat exchanger. When the temperature of the water – as it returns to the boiler – is less than 54 degrees C, the boiler will run in what is known as ‘condensing mode’.
Is the boiler thermostat the same as the hot water cylinder?
If you have a regular boiler with separate hot water cylinder, your boiler thermostat should always be set to a higher temperature than the cylinder thermostat, otherwise the hot water cylinder will never get up to temperature.
Can a smart thermostat be used to control a boiler?
With the advent of smart thermostats, it has become easier to control boiler and room temperatures. When you install a smart thermostat to your boiler, you use it to control the boiler temperatures, to program when the boiler goes on or off and to detect the temperature of the surrounding.

How does the thermostat work in a boiler?
Your boiler will always have a thermostat. This thermostat is usually marked in number from minimum to maximum. This range sets the temperature that will be pumped from the boiler via the radiators to heat your room. When you set the temperature high, your room will heat fast.
When does a gas boiler turn on and off?
The gas burner on a conventional boiler comes on when there’s a call for heat and turns off when the thermostat tells the boiler that the call for heat is satisfied (that is, the room reaches the setpoint temperature of the thermostat). As far as a conventional boiler burner is concerned, there is not an in between; it is either on, or it is off.
What do the numbers mean on a boiler thermostat?
Your boiler will usually have a dial on it, marked in numbers or from minimum (min) to maximum (max). This sets the temperature of the water that will be pumped from the boiler through the radiators. The higher this is set, the quicker it will heat your home.
