Rads too hot to touch but boiler at low setting

    Hi,

    I have a dormer house built in 02 which has a grant oil boiler heating 11 radiators.

    When the heat is on, the rads are almost too hot to touch. The setting on the boiler is down at it's lowest and I dont see any other thermostats on the system.

    I would appreciate an opinion before I call out the pro's. My concern is that I might be doing damage to pies/rads with the high heat and burning a lot of oil!

    It's possible the thermostat on the boiler is acting up, 55oC would be the lowest setting and to some that temp in a radiator would be to hot to touch. The only way to know for sure is to get a thermometer to measure the surface temp of the radiator.

    Maybe get a service technician out (for your annual boiler service) and make sure he checks this for you, it could be as simple as the thermostat hanging halfway out of it's housing tube, or possibly it could be faulty (but not totally failed)

    Remember, you can adjust down the temperature of each radiator in the mean time

    Very hot rads are never a good thing, especially if children are about and can cause some nasty burns, had even deaths have been recorded with rads where a small child has become trapped (such as falling between a chair and a rad and couldn't get free) extreme I know but it has happened
