Combi Boiler Installation in San Francisco, CA

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 San Francisco, CA 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.

Call Reliable Boiler Service at (866) 456-6311 to find out whether combi boiler installation fits your house.

Combi Boiler Installation FAQs

Frequently asked questions about Combi Boiler Installation

Questions we hear most often about Combi Boiler Installation in San Francisco, CA.

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.
Do you handle steam boilers in older buildings?
Yes. Reliable Boiler Service connects owners with technicians who work on one-pipe and two-pipe steam, including air vents, pressuretrols, sight glasses and low-water cutoffs.
What should I do if my boiler is leaking?
Turn the boiler off, close the fill valve if water keeps spreading, and call (866) 456-6311. Note where the water is coming from, since that decides between a repair and a replacement.
Are there rebates for high-efficiency boilers?
Many gas utilities and state energy programs offer rebates on qualifying condensing boilers. Terms change often, so check your utility's current program before you buy.
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.
