Steam Boiler Repair in Portsmouth, NH

Steam heat runs on different rules from hot water. A residential steam boiler only needs a fraction of a pound of pressure to push steam through a house, so the pressuretrol should be set low. Cranked up high, it brings short cycling and banging rather than more heat.

The sight glass on the side shows the water line, which should sit around the middle when the boiler is cold. Water that bounces wildly while the boiler runs usually means oil or dirt on the surface, and the boiler needs skimming.

Banging pipes are mostly water hammer from a pipe that lost its pitch or a radiator tilted the wrong way. Cold radiators on a one-pipe system often trace back to a clogged air vent.

Reliable Boiler Service connects Portsmouth, NH property owners with technicians who know steam: main vents, radiator vents, pressuretrols, low-water cutoffs, skimming and near-boiler piping.

Steam Boiler Repair FAQs

Frequently asked questions about Steam Boiler Repair

Questions we hear most often about Steam Boiler Repair in Portsmouth, NH.

Talk to a real person
Why is the relief valve on my boiler dripping?
A relief valve that drips or opens near 30 psi usually means a waterlogged expansion tank or a fill valve letting too much water in. Replacing the valve alone rarely fixes it.
Why are my radiators cold at the top?
Air is trapped in them. Bleed each radiator with a radiator key until water runs steadily, then check the boiler pressure and top it up if needed.
My boiler is running but the house is cold. What should I check?
Look at the pressure gauge, listen for the circulator pump, and feel the pipes leaving the boiler. Hot boiler with cold pipes usually means a pump or zone valve problem.
What should I do if my boiler is leaking?
Turn the boiler off, close the fill valve if water keeps spreading, and call (866) 456-6311. Note where the water is coming from, since that decides between a repair and a replacement.
How do I know if my boiler is the right size?
A room-by-room heat loss calculation is the only real answer. Boilers that short cycle on mild days are often oversized for the house.
