Grant oil burner - thermostat query

    I've moved into a house recently where the radiators get warm but not hot. There are not hot pockets and cold pockets in the radiators but I tried bleeding the radiators anyway and found that they were perfectly fine.

    So I opened the front cover of my Grant boiler (outside the house) to find that the thermostat had been set to 35 celcius. This seems very low to me but I'm no expert at all.

    So can anyone tell me what temperature I need to set the boiler to so that my radiators will be 'hopping' (i.e. hot to touch, rather than warm) and give me good heat output?**

    Also, if I want the oil heating to give me good hot water in the immersion tank what temperature should the boiler thermostat be set to?





    **I know my room thermostat will let the heating kick in or out but that wasn't the problem. The house was freezing today, having been empty for about two weeks, with no heat.

    65 to 70 degrees,if you have your thermostat set below 60 degrees and you are not using you immersion heater regularly you are at risk of legionnaires disease.New oil boiler thermostats dont allow the temperature to be set below 60 degrees.A new thermostat would be a good investment long term

    Thanks for that reply! With two kids and baths to be had three times a week we'll be using the immersion regularly enough :D I had upped the temperature to 58 degrees today when I was in the house (took the front panel off the boiler to do that of course) but I'll up it to 65 when I'm out there tomorrow and see how that works out. :)

    I will probably have other queries around the set up for this boiler later but I'll come back to that once I have the rads working to full effect.
