How a Boiler Works

- Circulator pump — pushes hot water through the loop
- Expansion tank — absorbs pressure as water heats and expands
- Baseboard loop — hot water out, cooler water returns

Boiler Service in Waterville, ME FAQs
Do you offer boiler service in Waterville, ME?
Yes. Waterville is part of our Kennebec County service area, and J&R Mechanical Services handles boiler service for homes throughout the area. Call (207) 902-8899 or book online to schedule.
Why does my boiler keep losing pressure?
Usually a leak somewhere in the loop — a weeping relief valve, a failed expansion tank, or a pinhole in old baseboard piping — or a faulty auto-fill valve. Topping it up every week hides the problem and pulls fresh oxygenated water into the system, which rusts it from the inside.
Should I switch from oil to gas or to a heat pump?
If natural gas runs to your home, a gas boiler usually cuts fuel cost and removes the tank. If not, a cold-climate heat pump paired with your existing boiler as backup is often a strong value. We price the options honestly.
