Does this happen to your radiators?
- Heating system slow to warm up
- Cold spots in the middle of radiators
- Unpleasant boiler noises (banging loudly and crackling)
- Frequent bleeding of radiators (letting the air out of your radiators)
Have you noticed your radiators are giving out less heat than they once did? It’s a common complaint caused by sludge and scale that has built up over time; and this makes your heating system less efficient and it will cost you money.
