Homeowner questions
Heating Repair FAQ.
What if the boiler is on but radiators are cold?
The issue may be circulation, controls, valves, air, sludge or balancing rather than the boiler itself.
Can oil heating affect hot water?
Yes. Many oil-fired systems heat both radiators and stored hot water.
Should I bleed radiators first?
You can check for trapped air if you know how, but do not open boiler casing or interfere with oil burner parts.
