Combi Boiler Installation in Yonkers, NY
Heat and hot water from one compact, wall-hung unit.
A combination boiler heats your home and provides on-demand hot water from a single wall-mounted unit, eliminating a separate water heater tank. For smaller Yonkers homes and condos, a combi boiler frees up space while delivering efficient, modern heating.
How a combi boiler works
A combination boiler does two jobs with one appliance. When the thermostat calls for heat, it heats water for your radiators or baseboard. When you open a hot tap, it diverts its full output to heat domestic hot water on demand, much like a tankless water heater. There's no separate storage tank, which frees up floor space and eliminates standby heat loss.
Most combi boilers are high-efficiency condensing units that wall-mount and vent through the side of the house with plastic pipe, so the old chimney may no longer be needed for the boiler.
When a combi is the right fit — and when it isn't
Combi boilers work well in small to medium homes with one or two bathrooms, where hot water demand is moderate. In larger homes with multiple bathrooms used simultaneously, a combi may struggle to deliver enough hot water at once. In those cases, a boiler paired with an indirect tank may be the better choice.
We look at your heating load, the number of fixtures, and how your household uses hot water before recommending a combi. We also check gas supply, since combis need a large volume of gas during hot water production.
Living with a combi boiler
Day to day, a combi boiler feels simple: hot water whenever you open a tap and steady heat from the radiators. There are a few habits worth knowing. Because the unit heats water on demand, running two showers at once shares the available output, so flow at each may drop slightly. When hot water is running, heating pauses briefly, which is rarely noticeable in a well-insulated home. Annual service keeps the heat exchanger clean and the condensate trap clear, and the system pressure gauge should stay in the range we show you at startup.
