Biasi 24s Combi Boiler Central Heating Issue

Hi Everyone,

About 4 or 5 days ago, My Biasi 24s combi Boiler’s has developed a strange problem. I am getting the required hot water but unfortunately, there is no central heating. The boiler is just four years old. What could be a reason behind this? Need your guidance.

Thanks in Advance


Hi Rob, if you are facing issues with central heating then firstly, you have to check the radiators. Secondly, make sure that central heating on the boiler is switched on. Thermostat & timers have to be set correctly. If central heating is still not working after checking the above-mentioned things, then definitely diverter valve is broken. Do call a boiler engineer to replace the diverter valve.
