When a tankless water heater is the better buy

Tankless is not right for every house. These are the cases where it usually pays.

  • Hot water runs out mid-shower
  • The tank takes floor space you need
  • A house that sits empty between visits
  • A tank that failed early on well water
  • You want the unit up off a wet floor
  • You are adding a bathroom

What a proper tankless water heater install includes

Most tankless complaints trace back to a shortcut at installation. These are the parts we never skip.

A real load calculation

Sized on how much hot water your household draws at once, not on the square footage of the house.

Gas line and venting

A tankless unit draws far more gas at once than a tank does, so it usually needs a larger line and its own venting. We do both, to code, as part of the job.

Water treatment first

Hard well water scales a heat exchanger fast. We test the water and tell you if treatment should come first.

Valves and a service plan

Isolation valves go on at install so the unit can be descaled properly, and we set the maintenance schedule before we leave.

Questions We Get Asked About Tankless Water Heater Installation

What people ask before switching to tankless.

How much does a tankless water heater cost installed?

Typically $4,000 to $7,500 on the Shore: $1,300 to $2,800 for the unit and the rest for labor, venting, gas line, and permit. Our tankless cost guide breaks it down.

How soon can you come out?

Often the same day, and usually within the week. We work 8:00am to 9:00pm, seven days a week, so evening and weekend visits count too. Book online or call (757) 824-9862 for a time.

Will my gas line support a tankless water heater?

Often it needs an upgrade, because a tankless unit draws far more gas at once than a tank does. We assess the line and handle the gas work and venting as part of the install.

Is a tankless water heater worth it compared with a tank?

It depends on how much hot water the household uses, and larger families see the benefit soonest. A tank runs $1,800 to $3,600 installed and lasts 10 to 12 years. See tank or tankless for the full comparison.

Can you replace a tankless water heater that is already there?

Yes. We replace tankless units whoever fitted them, and we check the gas line, venting and water treatment at the same time so the new one does not fail the same way.
