Boiler Replacement in Southeast DC

Updated November 9, 2026

Signs it is time

Frequent pressure loss, rust around the base, rising gas bills and a boiler older than 25 years are common reasons to start planning a replacement.

After the new boiler

We walk you through the new controls, show you the pressure gauge and explain what normal looks like, so you can spot a problem early. We also leave model and serial numbers for your records.

Older homes east of the river

Many older houses in Deanwood, Hillcrest and Anacostia still heat with boilers and radiators. A new boiler keeps that steady radiant heat while using less gas.

Chimney and venting

Old boilers often vent through a masonry chimney. Modern boilers usually vent through PVC out the side wall, and we plan that route during the quote.

Repair or replace

If an old boiler leaks, cycles constantly or costs a lot to run, replacing it can cut gas use and improve comfort. If the heat exchanger is sound, a repair may be the smarter choice.

Modern boiler options

High-efficiency condensing boilers vent through PVC and use less gas. Combi boilers also make hot water on demand and can replace the water heater.

Keeping your radiators

A new boiler works with your existing radiators. We size it to the radiators and piping you have.

What installation includes

Removal of the old boiler, new boiler and venting, circulator and expansion tank where needed, system flush, filling, air purging and testing every zone.

Timing

Most boiler replacements take one to two days. We plan to keep you without heat for as little time as possible.
