Hot Water Heater Installation in Maryland
Gas, electric and heat-pump water heaters installed to code with expansion control, proper venting and a permit — usually same day.
Water heater replacement is the job most often done badly, because it is the job most often done in a hurry. A tank fails, the basement floods, and someone installs a new one in ninety minutes without a permit, without a thermal expansion tank, with the old undersized flue and with a dielectric mismatch at the connections. It works. It also fails early, and it fails an inspection at resale.
We size the replacement to your household's actual peak demand, check the venting and combustion air, install expansion control where the water service has a check valve or pressure-reducing valve, and pull the permit. We also flag the option most homeowners are never offered: a heat pump water heater, which uses roughly a third of the energy of a conventional electric tank and currently attracts the largest incentives available on any water heating equipment in Maryland.
Where we workScope
What the job actually includes
- First-hour rating sizing based on real household peak demand, not just tank gallons
- Gas, electric, or heat-pump (hybrid) water heater options priced side by side
- Thermal expansion tank where required — mandatory on closed systems with a PRV or check valve
- New shutoff, flexible connectors, dielectric unions and sediment-appropriate fittings
- Code-compliant temperature and pressure relief discharge piping to an approved termination
- Correct venting: verified draft on atmospheric units, sealed vent on power-vent, condensate on condensing units
- Seismic-free-standing safety straps where applicable, drain pan and pan drain over finished space
- Old tank hauled away and permit filed with the county
Maryland specifics
Code, permits and rebates
Montgomery County requires a permit for water heater replacement, and inspections check relief valve discharge piping, expansion control and venting. Heat pump water heaters are strongly incentivized in Maryland: EmPOWER Maryland rebates through Pepco combine with the federal 25C credit, and for many households the effective cost lands close to a standard electric tank. Note that heat pump water heaters need roughly 700–1,000 cubic feet of air volume or a louvered door, which rules out the tightest closets — we check that before recommending one. Homes on well water in Olney, Glen Hills and outer Potomac should also plan on sediment management, which shortens tank life if ignored.
Licensing
MD HVACR Contractor License #01-XXXXX. All refrigerant handling is performed by EPA Section 608 certified technicians, and equipment replacement is permitted and inspected through the county.
Process
How we run a water heater installation job
-
Size to demand, not to habit
Two bathrooms running back-to-back showers and a laundry cycle is a first-hour-rating problem, not a gallon problem. A well-chosen 40-gallon high-recovery gas unit can outperform a 50-gallon electric for the same household.
-
Check the venting and combustion air
If a high-efficiency furnace or boiler was installed earlier and now vents out a sidewall, your water heater may be alone in a chimney sized for two appliances and unable to establish draft. This is one of the most common unsafe conditions we find in older Montgomery County basements.
-
Verify expansion and pressure
We check incoming water pressure. Above 80 psi requires a pressure-reducing valve; a closed system requires a thermal expansion tank. Skipping expansion control is what causes relief valves to weep and tanks to fail years early.
-
Install, test and permit
New unit set on a proper pan, connected, filled, purged of air, lit and draft-tested. We file the permit and meet the inspector.
Pricing
What moves the price
We do not publish a single number, because a number without your house attached to it is marketing rather than information. These are the variables that actually decide what a job costs, and we itemise all of them in writing before any work begins.
Fuel type and technology
Standard atmospheric gas is the least expensive. Power-vent gas costs more and is required when there is no usable chimney. Heat pump water heaters cost the most up front and the least to run, and carry the largest available rebates.
Code corrections on an old installation
Missing expansion tank, improper relief discharge, no drain pan above finished space, or an undersized flue all get corrected as part of a permitted installation. On a 25-year-old install, expect at least one of these.
Location and access
A tank in an open basement is straightforward. A tank in a third-floor closet, a crawlspace, or an attic in a Germantown townhouse is a different labor picture — and needs a pan and drain that actually goes somewhere.
