Water Heater Installation in Melrose, MA
Water heater installation covers setting a new unit, connecting water, fuel or power and venting, and testing it before you use it. This page is for planned jobs: a new home, a remodel, a move from an old boiler setup or a family that wants more hot water than the current tank gives.
Call us to talk through your house, the options and a schedule that suits you.

Tank versus tankless: choose before you buy
The biggest early decision is whether to store hot water or heat it on demand.
Storage tank
- Lower upfront cost
- Simple to replace later
- Runs out when the tank empties
- Takes floor space
Tankless
- Heats as you use water
- Smaller footprint, wall mounted
- Needs correct gas line sizing and venting
- Needs periodic descaling
Our tankless water heater page covers on-demand units in detail.
What we check at your house before quoting
A heater is only as good as the space around it. These items shape the work.
- Fuel and supplyIs there a gas line near enough, or an electric circuit with spare capacity in the panel?
- Vent pathA gas unit needs a proper flue or vent route. A change in type can change the vent.
- Space and clearanceHybrid units need airflow around them and a place for condensate to drain.
- Drain and panA floor drain or pan helps if the tank ever fails above living space.
- Existing pipingOld shutoffs, corroded fittings or worn supply lines are cheaper to renew while the heater is open.
- Household demandThe number of bathrooms and people sets the tank size or the flow a tankless unit needs.

Permits for a planned install in Melrose
Melrose publishes a $40 plumbing fee for a water heater and a $40 residential fee for a gas water heater on its fee schedule. Ask Melrose Inspectional Services whether your installation needs a permit and who files it.
A licensed plumber normally pulls any needed permit, and the city says printed permits are posted at the job site. Plumbing and gas inspections run Monday to Thursday, and online review can take 2 to 3 weeks, so a planned job should allow time.

What affects the cost of an installation
Sizing hot water for your household
Sizing depends on the unit's rating and your habits. This table is a general guide, not a rating.
| Household | Tank heater | Tankless |
|---|---|---|
| 1 to 2 people, 1 bath | Smaller tank is often enough | Entry-level flow can work |
| 3 to 4 people, 2 baths | Mid-size tank, watch back-to-back showers | Mid flow rating suits most |
| 5 or more people, 3 baths | Large tank or two heaters | Higher flow rating or two units |
Ratings vary by brand. We check labels before recommending.

Questions we hear
It depends on your demand, space and gas supply. A tank costs less up front. A tankless unit frees floor space and heats on demand, but it needs correct gas and vent sizing and periodic descaling.
Often yes, but it changes the supply lines, vent, and drain. A site visit shows what is practical. Venting for gas units has the most limits.
A pan with a drain line is a good idea whenever the heater sits above living space or finished areas. Some installs call for one. We check the setup on site.
A straightforward swap takes part of a day. New venting, a new gas line or a new circuit adds time. We give you a schedule at quote time.
A licensed plumber normally pulls any permit that is needed. Melrose lists water heater fees on its schedule, and Inspectional Services at 781-979-4135 can confirm what your job requires.
Sometimes. You need a spare circuit in the panel and, for hybrids, room for airflow and a condensate drain. We can review it by phone and at a visit.
