We've just purchased and moved into a new house. First child expected in 6.5weeks so I could do with making sure the heating is all working nicely.
We have 7 radiators and 2 flat ladder towel radiators in the house.
4 radiators + 1 flat ladder towel radiator downstairs
3 rads + 1 ladder upstairs.
I've bled all the radiators and made sure all the valves are open (no thermostats on radiators).
The two biggest radiators (lounge and hallway) are stone cold and as a result the house isn't that warm and we're topping up the lounge with an electric oil filled heater. There's no heat at the top or bottom and the pipes at each end are also stone cold.
All other radiators and the two ladders are piping hot (except a pretty old looking radiator in our bedroom which gets warm but not scolding hot like the others).
Where do I start? If it is stuck valves or there was a build up of sludge in the rads I'd still of expected one of the pipes at the end of the rad to have some heat, but they don't (is this correct?).
I can spanner a bit, so I'm happy to have a go as I don't think I'm going to make it any worse before having to call in a plumber.
Anyone any ideas?
