Most Pittsburgh homes have natural gas, so we install gas tankless far more often than electric. But there’s a real place for electric tankless, and when it’s the right call, it’s the right call. If your home has no gas service, or you’ve got a remote bathroom that takes forever to get hot water, electric tankless is worth a serious look.

When electric tankless is the right choice

Electric tankless makes sense in three Pittsburgh scenarios:

1. No natural gas available. Some homes in the South Hills, North Hills, and rural Allegheny County edges don’t have gas service to the property, or running a new line is too expensive. Electric tankless is one of the few ways to get true on-demand hot water without gas.

2. Point-of-use applications. A small electric tankless mounted under a sink, in a remote bathroom, in a garage workshop, or feeding a single shower can be a great fix. You stop waiting on hot water and you don’t have to upsize your main tank.

3. ADU, addition, or finished basement. When you’re adding a kitchenette or a bathroom and running a hot water line all the way from the main heater would mean ripping up the house, a small electric tankless at the new fixture often costs less than the plumbing run.

Where electric tankless struggles

Whole-home electric tankless is a tougher fit in Pittsburgh than it is in milder climates. The reason is incoming water temperature. Pittsburgh ground water enters your home at about 45 to 50 degrees in winter. To deliver shower-temperature water (105 to 110 degrees), an electric tankless has to raise that water 55 to 65 degrees in a single pass.

A whole-home electric tankless big enough to do that runs 27 to 36 kilowatts. That’s roughly 113 to 150 amps at 240V. Most older Pittsburgh homes have a 100-amp main service, and even a typical 200-amp service can’t always spare that load. So a whole-home electric tankless in Pittsburgh often means upgrading the electrical service first.

For most homes without gas, a heat pump water heater is a better choice than electric tankless. It uses a fraction of the power, qualifies for the federal tax credit, and gives you a buffer tank.

We’ll talk through this honestly during the visit. If electric tankless is right for your home, we’ll install it. If it isn’t, we’ll show you the alternatives.

What we install

Whole-home electric tankless for homes with adequate 200-amp (or 320-amp) electrical service. Stiebel Eltron, Rheem, and EcoSmart units depending on flow requirements and your fixture count.

Point-of-use electric tankless under sinks, in remote baths, garages, and additions. Compact units in the 6 to 18-kilowatt range that mount on the wall and feed one or two fixtures.

Mini-tank electric water heaters (2.5, 4, and 6-gallon units) for cases where a true tankless is overkill or doesn’t fit the electrical service. These give you a small reservoir of hot water at a remote fixture without the load of a tankless.

What an electric tankless install includes

1. Verify the electrical service is adequate. This is step zero. If it’s not, we’ll quote the electrical service upgrade alongside, or we’ll recommend an alternative.
2. Run new dedicated circuits. A whole-home electric tankless needs two or three 40 to 60-amp double-pole breakers and dedicated runs from the panel.
3. Mount the unit on the wall. Wall-mount, smaller than a briefcase for point-of-use, smaller than a microwave for whole-home.
4. Run new water lines and shutoffs. Inlet, outlet, isolation valves.
5. Install a Wahl flush kit. Annual flushing is required to prevent scale damage to the heating elements.
6. Pull the permit. Test, commission, and walk you through it.

We don’t separate electrical and plumbing. Wahl runs licensed plumbers and we coordinate any electrical work through trusted local partners or our in-house electrical capabilities, so you’ve got one company on the hook for the whole job.

What it costs

We present exact pricing in your home after a free in-home estimate. Whole-home electric tankless sits in the mid-to-upper tiers of our water-heating ladder, plus any electrical service upgrade if your panel can’t support the load. Point-of-use electric tankless and mini-tank installs are at the entry tier, sized to the single fixture or remote location they serve.

We come out, measure your electrical capacity, check the plumbing run, and put real numbers on paper. Part of our process is presenting the numbers in person, with both standard and Wahl Club member rates shown side by side.
