How to change the temperature on my Boiler

Your boiler’s controls

 

Most modern boilers have temperature controls, radiator controls, and thermostats for the boiler, cylinder tank, or room. Yours might have all, few, or none of these things. Whatever your boiler, consult its manual and get acquainted with it. You can find most manuals online. They might also tell you what temperature your boiler should be set at in summer and winter.

 

Setting the boiler controls

 

Once you’re acquainted with your boiler, its settings, and how it shows information, you should be able to alter the settings. Temperature settings are usually changed by a dial or a digital display – make sure you’re changing the correct settings!

 

An important thing to consider: Setting your boiler’s temperature higher will give you hot radiators, but it could decrease its efficiency. Ramping up the temp to max could decrease it by up to 20%, and send your heating bills skyrocketing. If you want a lovely warm home and a long-lasting boiler, it’s about getting the right balance.
