Boiler Installation in Hyattsville, MD

A large share of the homes in Hyattsville, Mount Rainier, Riverdale Park, and the surrounding historic neighborhoods were built before forced-air heating was standard, and many still run on boilers — hot water or steam feeding cast-iron radiators, with no ductwork anywhere in the house. If you own one of these homes, a boiler is not an outdated system to rip out; it is often an excellent, comfortable, long-lived way to heat, and replacing it with the right new boiler preserves what works while gaining efficiency. Boiler installation is a different discipline than forced-air work, though — the piping, sizing, and controls all matter in ways a furnace installer may not appreciate. We install boilers with the specific care hydronic systems require.

Hydronic Heat Is Different — and Often Better

Boilers heat with water rather than air, and that changes the comfort. Hot-water (hydronic) systems circulate heated water through radiators or baseboard, warming rooms with steady radiant and convective heat that many people find more comfortable and even than forced air — no blowing air, no sudden temperature swings, no dust pushed through ducts. Steam systems, common in the oldest homes, work on a different principle but share that quiet, radiant character. For a home built around hydronic heat, replacing a failing boiler with a new one is usually far more sensible than gutting the house to install ductwork, and it keeps the comfort the home was designed to deliver.

Boiler Types We Install

High-efficiency condensing boilers — modulating-condensing units that reach efficiencies in the 90s by extracting heat from the flue gases, with modulating output that matches the heating load closely. The strongest efficiency choice for most hot-water systems.
Conventional cast-iron boilers — durable, proven hot-water boilers, a sound choice where a condensing unit is not the right fit for the existing system.
Steam boilers — for the steam-heated homes among the oldest housing stock, where the replacement must be correctly matched to the existing radiation and piping.
Gas conversions and replacements — performed under our WSSC Water gasfitter license, with the gas work properly permitted and inspected.

Sizing and Near-Boiler Piping: Where Boiler Installs Succeed or Fail

Two things determine whether a boiler installation performs, and both are easy to get wrong. The first is sizing. A boiler should be sized to the home’s actual heat loss and, for steam and much hot-water work, to the connected radiation — the total heat-emitting capacity of the radiators. An oversized boiler short-cycles, wastes fuel, and on steam systems can cause uneven heating and banging pipes. The second is the near-boiler piping — the arrangement of pipes immediately around the boiler. Condensing boilers need proper primary-secondary piping to protect the unit and deliver rated efficiency, and steam boilers are especially unforgiving: manufacturers specify exact near-boiler piping, and deviating from it produces wet steam, poor performance, and noise. We install to the manufacturer’s specifications, because a boiler is only as good as the piping around it.

Adding Air Conditioning to a Boiler-Heated Home

The most common frustration in a hydronic home is the lack of air conditioning — there are no ducts to carry cool air. The good news is that you do not have to choose between keeping your comfortable boiler heat and having modern cooling. A ductless mini-split system adds efficient air conditioning (and supplemental heating) without any ductwork, pairing perfectly with a boiler-heated house. Many homeowners in the historic neighborhoods keep their radiators for winter warmth and add ductless for summer cooling, getting the best of both. We can plan a boiler replacement and a cooling solution together so your whole-home comfort is handled.

Permitted, Gas-Licensed, and Commissioned

Boiler installation involves gas, water, and venting, and we handle all three to code. The gas connection is made under our WSSC Water gasfitter license; the mechanical permit is pulled through the Prince George’s County Department of Permitting, Inspections and Enforcement; and the venting — whether a condensing boiler’s PVC sidewall vent or a conventional boiler’s flue — is installed and verified correctly. We commission the finished system: setting controls, purging air from hot-water systems, checking the pressure and expansion tank, and confirming safe combustion and venting. The result is a boiler that heats your home efficiently and safely for the long service life these systems are known for.

Frequently Asked Questions

Should I replace my old boiler or switch to forced-air heating?: For most boiler-heated homes, replacing the boiler is the better choice. Converting to forced air means installing ductwork throughout a house that has none, which is expensive, disruptive, and often difficult in older homes with plaster walls and no cavities for ducts — and it sacrifices the steady, comfortable radiant heat a hydronic system provides. A new boiler preserves that comfort and gains efficiency. If your goal is to add air conditioning, you can keep the boiler for heat and add a ductless mini-split system for cooling, rather than converting the entire heating system.
What is a high-efficiency condensing boiler?: A condensing boiler reaches efficiencies in the 90s by extracting additional heat from the flue gases that a conventional boiler sends up the chimney, condensing water vapor out of them in the process and venting cool exhaust through PVC. Most also modulate, adjusting their output to match the heating load closely rather than cycling fully on and off, which improves both efficiency and comfort. Condensing boilers are an excellent choice for many hot-water systems, though the installation requires proper piping and condensate handling. We assess whether a condensing or conventional boiler is the right fit for your specific system.
Why is boiler installation different from furnace installation?: Boilers heat with water rather than air, so the installation involves piping, circulators or steam mains, expansion tanks, and controls that a forced-air furnace does not — and getting the near-boiler piping right is critical. Condensing boilers need proper primary-secondary piping to protect the unit and deliver rated efficiency, and steam boilers require exact manufacturer-specified piping or they produce wet steam, poor heating, and noise. Sizing must account for the connected radiation, not just square footage. This specialized knowledge is why a boiler should be installed by someone experienced with hydronic and steam systems, which we are.
Can I keep my radiators and still get air conditioning?: Yes, and it is a popular solution in this area’s historic homes. Because your radiators are heated by a boiler and not connected to any ductwork, you can add a ductless mini-split system for air conditioning without disturbing the heating system at all. Each indoor head cools its zone through a small line-set connection to an outdoor unit. Many homeowners keep their comfortable radiator heat for winter and use ductless cooling for summer, and a ductless heat pump can also provide efficient supplemental heating. We can plan your boiler and cooling together for complete year-round comfort.
How long do boilers last?: Boilers are known for long service lives — a well-maintained cast-iron boiler can last several decades, often outlasting forced-air furnaces considerably, and modern condensing boilers also offer long life when properly installed and maintained. Longevity depends heavily on correct installation, particularly the near-boiler piping and sizing, and on regular maintenance that keeps the system clean and the water chemistry and pressure correct. This durability is part of why replacing a failing boiler with a new one, rather than converting to another system, is usually the sound long-term decision for a hydronic home.
