Combi Boiler Installation in Seattle, WA

A combi boiler heats the house and makes domestic hot water on demand from one wall-hung unit, which frees up the floor space an indirect tank used to take.

The number that matters is flow rate at a given temperature rise. Incoming water in winter can arrive in the 40s, so a combi that looks fine on paper may only keep up with one shower at a time. Reliable Boiler Service connects Seattle, WA homeowners with installers who check fixture count, incoming water temperature and gas supply before recommending a combi over a heat-only boiler with an indirect tank.

Gas line size is a frequent surprise. A combi draws high input when hot water is running, and an undersized line from the meter starves the burner.

Hard water also shortens the life of the plate heat exchanger, so a scale filter is worth discussing in some areas.

Combi Boiler Installation FAQs

Frequently asked questions about Combi Boiler Installation

Questions we hear most often about Combi Boiler Installation in Seattle, WA.

Talk to a real person
Do condensing boilers work with old cast iron radiators?
They can, but they only condense when return water comes back cool. Outdoor reset control and properly sized radiators make the difference.
Why does my steam heat bang and hammer?
Banging usually comes from condensate trapped in a pipe that lost its pitch or a radiator tilted the wrong way. A pressuretrol set too high makes it worse.
How often should a boiler be serviced?
Once a year, ideally before the heating season. Steam boilers with a float type low-water cutoff also need regular blowdown through the winter.
My boiler is running but the house is cold. What should I check?
Look at the pressure gauge, listen for the circulator pump, and feel the pipes leaving the boiler. Hot boiler with cold pipes usually means a pump or zone valve problem.
How do I know if my boiler is the right size?
A room-by-room heat loss calculation is the only real answer. Boilers that short cycle on mild days are often oversized for the house.
