A converted basement heating system: white Navien combi unit on black backer board with symmetric copper piping, expansion tank, and zone circulators — Oil-to-gas conversion, September 2025

What we do

High-efficiency tankless combi boilers

Navien tankless combi systems that heat your home and give endless hot water from one wall-hung unit. We size every install to your house: flow rates, gas pressure, and the hot-water demand that actually happens under your roof.

September and December 2025 posts each describe a Navien combi conversion; a January 2025 post shows another Navien install.

Boiler replacement, gas and oil

Old boiler out, new boiler in, properly piped and wired. Gas or oil, we replace failed systems with quality equipment and tidy copper.

“We are your boiler and heating specialists!”: our own words on a September 2025 job post.

Oil-to-gas conversions

Still heating with oil? Converting to natural gas with a new high-efficiency combi system can cut heating costs and free up the space an old boiler hogs. We handle the full conversion in the basement mechanical room.

Our September 2025 post documents a package-unit conversion to a Navien combi tankless system, “a huge efficiency upgrade going from oil to natural gas with some and features!”

Homes and businesses

Residential and commercial heating work across New Haven and Fairfield County, from single-family basements to commercial spaces.

Our own service description: “commercial and residential plumbing/heating company.”

Gas or oil, sized before it's set

Every system, calculated for the house it serves

The conversion job above replaced an old oil package unit with a new Navien combi tankless system. The homeowner got heat and endless hot water from one high-efficiency unit, with the copper, expansion tank, and zone circulators arranged like a schematic on the wall.

Calculation comes before equipment: flow rates, gas pressure, and the hot-water demand of the house decide what gets installed.
