Where installs come from

Four jobs that are installations, not replacements

The word matters because the scope, the permit and the price are all different.

New construction & ADUs

A heater going into a building that has never had one. Capacity sized to the fixture count rather than to whatever was there before, and positioned so the venting run is short and the drain is real.

Remodels & relocations

Moving a heater out of a closet a bathroom now needs, or out of a finished space where a future failure would do damage. Usually the cheapest time to also upsize.

Fuel conversions

Electric to gas, or gas to electric heat pump. Different venting, different circuit, different permit — and on the heat pump side, an Energy Trust rebate.

Format conversions

Tank to tankless. Nearly always a gas line question first and a venting question second, which is why the honest quote comes after a site visit and not over the phone.

What gets sized

The five things that decide whether an install lasts

None of these are visible once the job is finished, which is exactly why they get skipped on a cheap quote.

Capacity. Sized on first-hour rating against the real fixture count, not on the label of the unit that happened to be there before. Getting this wrong is why people run out of hot water in a house that has a new heater.
Gas line. A condensing tankless unit can demand three to five times the input of the tank it replaces. If the existing line cannot carry it, the unit will short-cycle and fault, and no amount of servicing fixes that.
Venting. Category III stainless or PVC on a condensing unit, correct rise and termination clearances, and a condensate route that does not freeze. Portland winters are mild but not that mild.
Electrical. A heat pump water heater needs a dedicated 30-amp circuit and enough surrounding air volume to work — roughly 700 cubic feet, or ducting. A closet with a louvred door is not automatically enough.
Drainage. A pan and a real drain line wherever the unit sits above finished space, plus condensate for anything condensing. Every heater eventually leaks; the only question is where the water goes.

Questions

Water Heater Installation in Portland, OR — straight answers

What counts as an installation rather than a replacement?

Anything where a heater is going somewhere it has not been before, or where the fuel, the format or the location changes. New construction, an ADU, a remodel, a garage conversion, moving a heater out of a closet, or a first tankless or heat pump.

Do you run the gas line and the venting?

Yes. Gas line sizing, venting, condensate, the expansion tank, the pan and the strapping are all part of the install and all part of the quoted price. A tankless conversion frequently needs a larger gas line than the tank it replaces, which is the single most common surprise on a quote that came from someone who never looked.

Can you install a unit I bought myself?

We would rather not, and here is the honest reason: the manufacturer's warranty on a big-box unit is usually shorter, the parts supply is different, and if it fails in year three you are the one chasing it. Where we supply the heater we stand behind the whole thing, unit and labour.

How far ahead do you need to know?

For new construction or a remodel, as early as you can — the position of the heater decides the venting run, the gas line size and whether you need a pan and a drain. Bringing us in at rough-in is much cheaper than working around decisions already made.
