When you need an installation

Installation goes beyond swapping an old unit. We handle the jobs that involve new connections, new locations, or a different system entirely:

  • A first water heater in new construction, an addition, or an ADU
  • Tank-to-tankless conversions with new gas and venting
  • Fuel changes — electric to gas, or adding a gas line
  • Relocating a unit to free up space or improve access
  • Upgrading capacity for a growing household
  • Garage, shop, or rental point-of-use units

Just swapping a failed unit for the same type? That's a replacement — we do those same-day.

Tank vs. tankless install

Tank — lowest install cost, simplest to service, quickest to put in. Great for like-for-like and tighter budgets.

Tankless — endless hot water, ~15–20-year life, wall-mounted to reclaim space; needs a larger gas line, dedicated venting, and condensate drainage. We size and quote both. For tankless service later, see tankless repair.

Every install is to Oregon code

A safe, resale-ready install means more than connecting pipes:

  • Plumbing (and gas/mechanical) permit pulled and inspected
  • Seismic strapping for Oregon's quake zone
  • Properly sized thermal expansion tank
  • New T&P relief valve, drain pan, and discharge line
  • Correct venting, combustion air, and condensate drainage

We register the warranty and leave you the paperwork.

Sized right

The right unit for your household

An undersized heater means cold showers; an oversized one wastes money heating water you never use. We size by household size, fixture count, and how much hot water you draw at peak — then recommend the unit that fits, not the one that's easiest to sell.

For tankless, we calculate peak flow rate so two showers and the dishwasher don't leave anyone cold, and confirm your gas line and venting can support it before we quote.

Honest sizing up front saves you from an expensive mismatch later.

Installation Guide

Water heater installation in Portland, Oregon

New tankless water heater installed on a wall in a Portland home Permitted& inspected

More than connecting two pipes

A water heater install done right is permitted, sized correctly, and brought to current Oregon code — seismic strapping, expansion tank, proper venting, and combustion air. Done wrong, it's a safety risk and a red flag at resale. We do it by the book, every time.

Tank, tankless, or heat-pump

The best system depends on your space, budget, and hot-water demand. We size and quote the realistic options for your home — including the gas, venting, or electrical a conversion needs — so you choose with full information.

Installs we handle across the metro

From a single new unit to a full conversion, we cover the jobs replacement alone doesn't:

  • First water heaters for additions, ADUs, garages, and shops
  • Tank-to-tankless conversions with new gas and venting
  • Fuel changes and capacity upgrades for growing households
  • Relocations to free up space or improve access
  • Gas line sizing for higher-BTU units

Replacement vs. installation

If you're simply swapping a failed unit for the same type, that's a same-day replacement. If you're changing systems, locations, or adding a unit, that's an installation — and we'll tell you which path fits and what it really costs.

Portland's permitting and inspection process protects you, and we manage it end to end. We pull the right permits, install to the Oregon Plumbing Specialty Code, coordinate inspection, and register the manufacturer warranty in your name.

Every install is performed by an Oregon-licensed, background-checked plumber and backed by a written workmanship guarantee — with no after-hours surcharge if an emergency turns a repair into a same-night replacement.

Installation, Answered

More water heater installation questions

How long does a water heater installation take?

A new tank install in an existing space typically takes two to four hours. First-time installs, relocations, and tankless conversions take longer because they involve running new water, gas, electrical, or venting — often most of a day. We give you a realistic timeline with the quote, and we leave the space clean and the unit tested before we go.

Do I need a bigger gas line for a tankless unit?

Often, yes. Tankless heaters fire at a much higher BTU rate than a standard tank, so the existing gas line and meter may need to be upsized to feed it properly. This is one of the biggest reasons a tankless conversion costs more than a tank swap. We check the gas supply during the quote so there are no surprises, and we're licensed to do the gas line work as part of the install.

Can you move my water heater to a new location?

Yes. Relocating a water heater — out of a closet to free up space, into the garage, or to a spot with better drainage — is a common install. It involves extending the water, gas or electrical, and venting to the new location and bringing it all to code. We'll assess whether the move is straightforward or whether the new spot needs venting or drainage work first.

What is a heat pump water heater, and is it right for Portland?

A heat-pump (hybrid) water heater pulls heat from the surrounding air to heat water, using far less electricity than a standard electric tank. It works well in Portland homes with a garage, basement, or utility space that stays mild and has enough air volume. The upfront cost is higher, but the long-term energy savings are significant — we'll tell you honestly whether your space suits one.

Do you offer financing on water heater installation?

Yes. A new install or tankless conversion is a planned investment, so we offer financing to spread the cost. Combined with the energy savings of a high-efficiency or tankless unit, financing often makes the better long-term system affordable now rather than settling for a cheaper short-term fix.

FAQ

Water heater installation questions

New unit, conversion, or ADU — call any hour and we'll size it up.

What's the difference between installation and replacement?

Replacement is a like-for-like swap of an existing heater. Installation covers new situations — a first unit in an addition or ADU, switching fuel types, converting to tankless, or relocating. Installation often involves new gas, electrical, water, or venting runs.

Should I install a tank or a tankless water heater?

Tankless gives endless hot water, long life, and a small footprint but costs more upfront and usually needs a larger gas line and new venting. A tank is cheaper to install and simple to service. We size both for your home and quote each.

Do you handle gas line and venting for a new install?

Yes. We're licensed for gas work and handle gas line sizing, venting, combustion air, and condensate drainage — all permitted and inspected. See our gas line service for related work.

Is a permit required to install a water heater in Oregon?

Yes — installation requires a plumbing permit (and mechanical/gas permit for gas work) and inspection in the Portland area. We pull the permits and install to the Oregon Plumbing Specialty Code, including seismic strapping and an expansion tank.

What size water heater should I install?

For a tank, roughly 40 gallons for 2–3 people, 50 for 3–4, larger for bigger households; for tankless we size by peak flow rate and simultaneous fixtures. We calculate the right capacity so you have enough hot water without overpaying to heat it.

Can you install a water heater for an ADU or addition?

Yes. New units for accessory dwelling units, additions, garages, and shops are a common install — we run the water, gas or electrical, and venting, then permit and inspect the work.

How much does water heater installation cost in Portland?

A standard tank install runs about $1,600–$2,800; tankless and fuel conversions run higher due to gas, venting, and electrical work. The flat price includes the unit, code upgrades, permit, and haul-away, quoted before we start.

Are you available for installs at night or on weekends?

Yes — a live dispatcher answers 24/7. Emergency replacements happen any hour; larger planned installs and conversions are usually scheduled, and either way there's no after-hours surcharge on the flat rate.
