Boiler not getting to temp

[Mark Christie]

Hi All ,

Was just wondering if anyone's had an issue with there boiler not reaching temperature. I currently have the boiler set to 72 for the radiator temp but I tried to set it at 80 but it wouldn't go over 74 degrees. The house gets warm and the radiators are working etc .

Anyone got any ideas ? The boiler is into a few months old .

Why are you trying to get it to 80? Mine is set to 70. Setting it higher will cost more to run as you have a bigger delta to heat. It is more likely you need to balance the radiators in the house rather than raise the boiler temp if the house is not getting up to thermostat temp (Is it reaching the temp you want?)

This. I rebalanced ours last weekend and the errors were slightly hilarious.

basically, if your upstairs is warmer than downstairs you either a) need a rebalance or b) need a power wash

80 and even 70 is a pretty high temperature to have your boiler set to. Mine is set to 62 which is the boilers recommended eco temperature. Never had any issues.

There are some boilers that lower themselves down so they don't reach the target temperature too fast. A boiler should take some time to reach it's target temp to give the radiators time to output some of that heat. Otherwise the boiler cycles too fast and never gets the house warm. Typically that would be a combination boiler. It's possible you have one of those boilers and don't know it.

80 is incredibly hot, dangerously so even, especially if you have kids. As others have said, it will cost way more to run. The only advantage is that the house might heat up from cold a few minutes quicker but it’s way more efficient to wait those few minutes.

I think mine only gets up to 65, even then the hot water is scolding hot and rads get hot enough to burn your skin if you kept bare skin on it for any length of time.

As others have said/implied, I imagine the internal logic is set to try and maintain a sensible delta T and try and keep the flow temperature at a value that'll allow proper condensing operation, remember also that the radiator temperature will be the mid point between the flow and return temperatures, so your radiators would likely be dangerously hot as generally anything over 50 too hot to hold for more than a couple of seconds
