Boiler Installation Brooklyn
Boiler installation from Plumber Brooklyn Crew replaces failing steam and hot water boilers in Brooklyn homes and apartment buildings.

Boiler Installation Plumbers in Brooklyn, NY
A new boiler is a twenty-five-year decision, give or take. Many Brooklyn boilers were sized by guesswork decades ago - bigger felt safer - and the oversized ones short cycle, bang and waste gas. A replacement is the one chance to correct that. We try boiler repair first when the boiler still has good years in it. Old boilers come out in pieces. The cast iron sections get broken down in the basement and carried up through the hatch, since nothing that size fits the stairs whole.

How Our Plumbers Replace a Brooklyn Boiler
When a Boiler Needs Replacing
Cast iron boilers often run 25 to 35 years. The end usually shows up as a crack: the boiler loses water daily and white vapor rolls out of the chimney. Other signs are quieter. Sections weep rust at the seams. The burner area is flaking. Repair bills arrive every winter, and a third repair in two seasons is a pattern.
Sizing a Steam or Hot Water Boiler
Steam boilers are sized to the radiators. We measure every radiator in the building, add up the square feet of steam, and match the boiler to that number - the size of the house does not enter into it. Hot water boilers are sized to the heat the building loses on a cold day. The nameplate on the old boiler is no guide, since the last installer probably copied the one before.

Near-Boiler Piping and Venting
Steam leaves the boiler wet unless the piping above it is right. The manual calls for a header, an equalizer and a Hartford loop in threaded black steel, at set heights above the water line. Copper shortcuts there cause banging and water in the mains. We replace the main vents on the same visit. On the flue side, an old masonry chimney often needs a liner to carry the cooler exhaust of a modern boiler.
Permits, Gas Piping and First Fire
Boiler replacement in NYC is permitted work, and the gas piping belongs to a licensed master plumber. Look up whoever you hire on the DOB license search. A bigger or relocated boiler can need gas line repair to feed it. At first fire we check gas pressure and draft, then skim the oil that new pipe sheds into the water. Many owners schedule water heater installation on the same job, since both units share the chimney.
