Combi Boiler Installation in Washington, DC

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 Washington, DC 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 Washington, DC.

Talk to a real person
Is a combi boiler a good fit for my home in Washington, DC?
A combi suits homes with one or two bathrooms and a gas line big enough for its hot water demand. Larger households often do better with a heat-only boiler and an indirect tank.
Why are my radiators cold at the top?
Air is trapped in them. Bleed each radiator with a radiator key until water runs steadily, then check the boiler pressure and top it up if needed.
What does a lockout code on my boiler mean?
The boiler tried to light several times and failed, so it shut itself off for safety. Note the code before resetting, since it narrows the cause down to ignition, flame sensing, venting or water pressure.
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.
