Tankless water heater installation across Queens
Queens is our busiest borough for tankless installations: detached and semi-attached houses in Bayside, Whitestone, Fresh Meadows, Forest Hills and Middle Village have the exterior wall for venting and often the gas capacity, and growing families in two-family houses in Ridgewood, Glendale and Richmond Hill want hot water that does not run out between two kitchens and three bathrooms. We also install combi boilers that do heat and hot water in one unit when the boiler is due anyway. Co-ops in Jackson Heights and Rego Park need the alteration agreement, which we handle.
From Greenpoint we reach western Queens over the Pulaski and Kosciuszko bridges in minutes, and the Van Wyck and Grand Central take us to Flushing, Jamaica and the Rockaways.

Questions from Queens
Who installs tankless water heaters in Queens?
GW Mechanical Corp installs and services Navien, Rinnai and Noritz tankless water heaters across Queens. We check the gas line and venting before quoting.
Is a tankless water heater worth it in Queens?
Yes if you run out of hot water or need the space, and the gas line can support it. We tell you honestly if a tank is the better choice.
Can a tankless water heater be installed in a Queens house or apartment?
Often yes. It needs a gas line that can carry 150,000 to 199,000 BTU and a vent route to an exterior wall or roof within the manufacturer's distance. We check both before quoting.
Does a tankless unit need maintenance in Queens?
A yearly descaling flush through the isolation valves and a clean inlet filter. NYC water is relatively soft, so scale builds slowly, but the annual flush is what gets 20 years out of the unit.
Do you repair tankless water heaters in Queens?
Yes. Error codes, scaled heat exchangers, blocked condensate lines, flow sensors and igniters on Navien, Rinnai and Noritz units, with common parts on the truck.
