Why is my boiler not circulating hot water?
CAUSE: One of the main reasons for hot water radiators not circulating is thermostat issues. Then, you must check the setting and then ensure the thermostat is working properly and is not stuck. If not, make sure you get it checked or have it replaced for the unit to work normally again.
How do you lubricate a circulating pump?
Motor bearings should initially be lubricated with 1/4 oz in each oil tube. For re-oiling, Bell & Gossett recommends the pump bearings be lubricated with 1 teaspoon of B&G 20# weight non-detergent oil at the start of each heating season. A SAE 20 oil or 10W-30 oil may be substituted if B&G oil is not available.
What happens if the central heating pump fails?
