My central heating radiators work upstairs and hot water is fine however the system only just heats some of the radiators downstairs , would it be better to replace inactive radiators , rather than do a power flush ?
The downstairs pipes are in concrete , the installation is 25 years old. The boiler works w/o problems and pump has recently been replaced. JT
Does it heat some of the radiators - or 'some' of each radiator? i.e.: are there cold spots on the rads. Sludge will tend to hit downstairs more due to its weight vs water.
Depends on condition of rads but probably would make more sense to update them to better efficiency ones.
Somebody decent local should be able to recommend best option after assessing system.
