Installed prices for Portland in 2026 — unit, labour, haul-away of the old heater and the Portland BDS permit included. A heat pump installation drops to roughly $1,300–$2,800 once the Energy Trust of Oregon rebate is applied. Anything that changes the scope — a fuel conversion, new venting, a gas line upsize, a relocation — is quoted separately and in writing before we start.

While the old one is out

The moment to fix what was wrong the first time

Replacement day is the only time the pipework, the venting and the location are all open at once. Most of what we find on a Portland replacement was non-compliant or undersized on the previous install, and fixing it now costs a fraction of coming back for it.

Seismic strapping

Two straps at the upper and lower third of the tank, anchored into structure. Required in Oregon and the most commonly missing item on an unpermitted install.

Drain pan and line

Any heater above finished space needs a pan and a drain line to somewhere sensible. It is the difference between a wet pan and a ruined ceiling when the tank eventually goes.

Expansion tank

Portland has backflow preventers on plenty of services, which makes a closed system. Without an expansion tank, every heating cycle spikes the pressure and the T&P valve takes the strain.

T&P discharge

Full-size pipe, downhill the whole way, terminating within six inches of the floor where it can be seen. No threads on the end, no reductions, no dead legs.

Worth asking

Replace like-for-like, or change something?

Going heat pump on an all-electric home brings up to $800 back from Energy Trust of Oregon
Going tankless on a gas home frees the floor space and brings up to $400 back
Upsizing from 40 to 50 gallons costs very little at replacement and a lot later
Relocating out of a finished space is easiest while the unit is already out

We quote like-for-like on every job because it is usually the right answer and always the cheapest. But if one of the alternatives genuinely pays back in your house, you will hear about it with the numbers attached — and then you decide, not us.

Questions

Water Heater Replacement in Portland, OR — straight answers

How much does a water heater replacement cost in Portland?

A 40-gallon gas tank runs $1,100–$1,600 installed and a 50-gallon $1,300–$1,900; a 50-gallon electric is $1,100–$1,700. Those are all-in numbers — unit, labour, haul-away of the old heater and the Portland BDS permit. Tankless and heat pump are higher and are priced on their own pages.

How long does a replacement take?

A like-for-like swap in an accessible spot is a single visit, usually two to three hours. It runs longer if the old unit is in a tight basement or a crawlspace, if the venting has to be rebuilt, or if you are changing fuel or format.

Do you take the old one away?

Yes, and it is in the price rather than added at the end. Old tanks are recycled for scrap steel rather than landfilled.

Do I have to replace it with the same size?

No, and it is worth asking the question. A household that has grown, or a second bathroom added since the last heater went in, is often the reason you are running out of hot water. Upsizing at replacement costs very little extra; doing it later costs the whole job again.

Is the permit really necessary?

Yes. Portland BDS requires a plumbing permit for a water heater replacement, and the inspection checks the seismic strapping, the T&P discharge, the venting and the expansion tank. We pull it, schedule the inspection and hand you the paperwork, included in the flat rate. Unpermitted work comes back to bite you at sale or refinance.
