What matters for boiler repair in Malden

Radiator valves

Old radiator valves leak at the packing and stems. Replacement is a routine fix.

Multi-family

One boiler failure affects several units, so owners should keep service records and a tech on call.

Hills and pressure

Taller buildings need higher boiler pressure to reach top floors. Low pressure leaves upper units cold.

Warning signs to watch for in Malden homes

  • No heat or hot water from the boiler
  • Boiler starts and shuts off, or shows a lockout light
  • Pressure gauge reading too high or too low
  • Water leaking from the boiler, pipes or relief valve
  • Unusual noises: kettling, rumbling, banging
  • Soot, smoke smell or yellow flames

Plain-language answers to the questions Medford homeowners ask most.

All guides
Technician checking a boiler pressure gauge in a basement

Boiler Pressure Too High or Too Low? What the Gauge Is Telling You

Most residential hot-water boilers run at roughly 12 to 20 psi when warm. Pressure creeping toward 30 psi usually points to a failed expansion tank or a leaking fill valve; pressure that keeps dropping usually means a leak or a relief valve that is letting water out. Steam boilers are different: they run at only ounces to a couple of psi.

Steam vs. Hot-Water Heat: How to Tell Which You Have and Why It Matters

Look at the boiler. A steam boiler has a glass sight tube showing a water line and a low-pressure gauge reading in ounces or a few psi. A hot-water boiler has a combined pressure and temperature gauge reading around 12 to 20 psi and usually a circulator pump. Radiators alone can be misleading, because both systems use cast iron.

Repair or Replace an Old Boiler? A Massachusetts Homeowner's Guide

Repair usually makes sense when the boiler is sound and a replaceable part has failed, such as an igniter, circulator, control or valve. Replacement is usually considered when the heat exchanger or a cast-iron section is cracked, repairs are frequent, parts are no longer available, or efficiency is poor. Mass Save may offer incentives for some high-efficiency equipment, which can change the numbers.
