Central Heating question

[pstones578]

Can someone please answer a question about my central heating system. Have a look at this picture.

A is the thermostat that we use to tell the system what temp we want, it's set to 24C. B is the heating boiler. At the bottom of the heating system is a panel (shown in picture C), which we have set to 6 (this is the max). The house temp is under 19C at the moment even though the heating has been on for hours ~ approx 5 hours. Picture D shows another thermostat that is set to it's lowest of 3, this can be seen on picture B too at the top left. Does anyone know what this thermostat is for as I'm wondering if I need to turn it up to get the overall temp of the system up?

thats a frost thermostat. It protects the boiler and pipework in extreme conditions. leave it set at 4-5c. Its irrelevant to your problem. If the rads have been hot for 5 hours and the house is not up to temp then the rads are too small.

probably this was a new build about 15yrs ago.

i would guess there that your boiler is situated in a garage and the stat u refer to is a frost stat which will bring the boiler in if it gets to cold
