Combi Boiler Installation in San Antonio, TX

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 Antonio, TX 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 San Antonio, TX.

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.
Can I convert my oil boiler to gas in San Antonio, TX?
If gas service is available on your street, yes. The job includes a new boiler, a properly sized gas line, a vent or chimney liner, and removal or abandonment of the oil tank.
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.
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.
