Choose by how you use hot water

Start with the household, then compare the equipment

Bathroom count alone will not size your water heater. If showers overlap with laundry, say so. Filling a large tub places a different demand on the heater than running a bathroom tap. Bring those details to the estimate, along with anything you disliked about the old system.

Option	What it offers	What to check first
Gas storage tank	A supply of stored hot water; a gas burner reheats it as needed.	Gas supply, the approved vent arrangement, combustion air and the available installation space.
Electric storage tank	A familiar tank setup that heats water with electric elements.	The circuit and reheating capacity, plus room to fit and service the new tank.
Tankless water heater	Water heated as it passes through the unit, without a large storage tank.	Simultaneous flow, incoming water temperature and the fuel or electrical capacity needed by the selected model.
Heat pump water heater	A storage tank that uses heat from surrounding air to help heat the water.	Room temperature and air volume, condensate drainage, sound and the model's electrical requirements.

A heat pump water heater supplies household hot water. It is different from the equipment described on our home heating and cooling heat pump page.

Capacity that matches the job

Tank gallons and tankless flow tell different stories

For a storage water heater

Start with how much hot water you use at the busiest time. First-hour rating estimates how much hot water a fully heated unit can supply in an hour, including reheating. Compare that rating with the household's busiest period of use.

A larger tank is not automatically the better answer. Recovery, available space and the way you use hot water matter too.

For a tankless water heater

Add up the fixtures that are likely to run together. Then account for how much the heater must raise the incoming water temperature. Colder incoming water increases the heating load, which can reduce the flow a unit can deliver at the chosen outlet temperature.

Tankless does not mean unlimited flow. It also does not eliminate the wait while hot water travels through a long pipe to a distant bathroom.

Understand the full installation

A tankless conversion involves more than mounting a smaller unit

A tank-to-tankless conversion may need different venting, a condensate route or changes to the gas supply. Electric tankless equipment can require a substantial electrical supply. We review the selected model and existing connections before treating a conversion as a direct replacement.

Leave room to service the equipment later. The layout needs room for inspection and future maintenance, including any manufacturer-required descaling. Ask where isolation valves, controls and service points will sit.

For a heat pump water heater, a tight closet or cold utility area needs a model-specific assessment. Airflow and condensate drainage belong in the plan from the beginning, along with where operating sound will be heard.

An estimate you can compare

Look beyond the equipment price

Your installed price includes more than the box. The home may need connection changes before the new heater can run safely. Compare estimates for the same scope; a low equipment price alone does not show what a replacement will cost.

Equipment: the model, capacity and fuel type, with the reason it fits your demand.
Removal and access: taking out the old heater, disposal and any access constraints.
Connections: necessary plumbing, electrical or gas work and any venting changes.
Installation requirements: required permits, inspection arrangements and protective measures appropriate to the location.
Completion: startup checks, operating instructions and the applicable equipment and labor warranty terms.

We offer free estimates for new water heater installations. Have details about the existing unit and its location ready when we speak. If the heater still works but has a fault, a repair assessment may help you decide whether replacement is necessary.

Prepare for installation day

Plan access and the interruption to hot water

Before the appointment, ask how long water service will be interrupted and which fixtures will be affected. A straightforward replacement and a fuel conversion involve different work. Parts, access and required inspections can change the schedule.

Confirm the scope. Review the equipment, connections and any agreed upgrades before the old unit is removed.
Prepare the work area. Clear a path to the heater and keep children and pets away while work is underway.
Replace and connect. The installation follows the selected equipment's requirements and the applicable local requirements.
Check and hand over. Review operation, controls and any follow-up inspection. Ask when the tank will be ready for normal use.

Keep the installation paperwork with the model and serial number (a phone photo is useful too). It helps when checking coverage or arranging service later.

Replace a failing heater or plan ahead

You do not need to wait for a leak to compare options. A planned replacement leaves time to assess different equipment and address installation changes. For an active leak, call (509) 300-1111 and describe the situation so we can discuss availability.

Equipment coverage and the warranty on installation work are separate. Compare both. Review the coverage for the quoted model and installation, including registration or maintenance requirements, before choosing equipment.

Common questions

A few things you may be wondering

How much does water heater installation cost in Spokane?

The price depends on the selected heater, access and connection work. A similar tank replacement can involve less work than switching fuel or converting to tankless. Request a free new-system estimate that identifies the equipment and installation scope.

Can a new water heater fit where my old one sits?

Often, but dimensions and required clearances must be checked. Two heaters with the same gallon capacity can have different dimensions. Heat pump models also need suitable air supply and a condensate route.

Will a tankless heater supply several showers at once?

Only if it is sized for the combined flow at the required temperature rise. Share which fixtures run together. The maximum advertised flow is not a promise of that output under every operating condition.

How long will I be without hot water?

Confirm the interruption when the installation is scheduled. The work depends on the connections and any upgrades or inspection requirements. Storage equipment also needs time to heat its tank after startup.

Should an older water heater always be replaced?

No. Condition, leak source, repair history and the cost of the actual repair matter alongside age. A serviceable control fault and an internally leaking tank lead to different recommendations.

Is a heat pump water heater suitable for a Spokane home?

It can be, provided the selected model suits the installation space and hot-water demand. Room temperature, available air, sound, drainage and electrical requirements need review. Check the manufacturer's instructions for that model rather than assuming every unit fits the same space.
