Boiler replacement and hydronic heating in Lowell, MA

Heat that is sized right, piped clean, and ready for winter

Do not wait until it is 10 degrees and the house is cold. We replace oil boilers, install combi boilers, and rebuild hydronic piping so zones actually match the house.

Heating equipment plus the piping, pumps, separators, gas, condensate, and flue work around it. We treat the board like part of the job — not a nest of leftover pipe.

  • Oil boiler replacement (including Saint Roch)
  • Navien NCB combi boilers (including 250/150H)
  • Hydronic piping and zone corrections
  • Grundfos circ pumps
  • Spirotherm dirt and air separators
  • Webstone/NIBCO isolation valves
  • Viega press fittings
  • Gas piping, condensate, and flue
  • Indirect storage tank swaps
Boiler piping

Proof

Deena and Tyler: Navien NCB 250/150H. Old equipment out ~9am Wednesday. Complete Thursday.
Peter and Lisa: new boiler piped for the zone it actually serves
Indirect storage tank swap
Do you only swap the boiler and leave the old piping?

Not if the piping is wrong. Undersized boilers and leftover zones are how people end up with no heat and a high bill.

How long is a combi swap?

The Navien job above was about a day and a half, start to finish, including finish work.
