FAQs
How do I determine the right-sized tank water heater for my Kelso home?
Start by counting the number of full bathrooms and high-demand fixtures (soaking tubs, multi-head showers, etc.). A typical guideline is 30–40 gal for 1 bath, 40–50 gal for 2 baths, and 50–80 gal for 3+ baths. Just as important is the First-Hour Rating (FHR), which should match your peak one-hour hot-water demand. Our technicians calculate FHR by reviewing your household size, simultaneous fixture use, and Kelso’s incoming water temperature (usually 50–55 °F). We’ll run the numbers on site and recommend the smallest tank that comfortably meets your needs so you avoid both shortages and wasted energy.
What does a standard tank water heater installation cost in Kelso?
For most homes, installing a 40- or 50-gallon natural-gas or electric tank runs $1,300–$2,200, including the heater, labor, new flex lines, a thermal expansion tank, disposal of the old unit, and sales tax. Costs rise if you need code upgrades such as seismic strapping, a drain pan with plumbed drain, or a dedicated shut-off valve—items the Washington State Plumbing Code now enforces. High-efficiency or power-vented models can add $400–$900. We provide flat, written quotes after a free on-site evaluation so you know the exact price before any work begins.
Do I need a permit or inspection to replace my water heater in Kelso?
Yes. Cowlitz County and the City of Kelso both require a mechanical/plumbing permit for any water heater replacement. The permit fee is modest (around $70–$90) and our company secures it on your behalf. After installation, a city or county inspector checks venting, T&P valve piping, seismic straps, and electrical/gas connections. Skipping the permit can void homeowners insurance, so we always include permitting and schedule the inspection as part of our service.
How long will I be without hot water during installation?
Most standard swaps take 2–3 hours. We shut off water and power/gas only after the new tank is on site, minimizing downtime to roughly 60–90 minutes. If we need to relocate the tank, run new venting, or correct code issues, the job can extend to 4–5 hours, but we’ll warn you in advance. Either way, you’ll have hot water again the same day.
What routine maintenance should I plan for after the new tank is installed?
1. Drain and flush 2–3 gal from the tank every six months to remove sediment, which is common in Kelso’s moderately hard water (about 90 ppm). 2. Test the temperature-and-pressure (T&P) relief valve annually to ensure it opens freely. 3. Inspect and, if necessary, replace the anode rod every 3–5 years; doing so can double tank life. 4. Keep the thermostat at 120 °F to curb scalding and save energy. We offer an affordable annual service plan that handles all of the above and maintains your manufacturer’s warranty.
Can I upgrade to a high-efficiency or heat pump water heater instead of a standard tank?
Absolutely. Heat pump water heaters (HPWHs) use about 60 % less energy than conventional electric tanks and qualify for BPA and federal tax incentives—up to $1,000 in combined rebates for Kelso customers served by Cowlitz PUD. They do require about 700 ft³ of ambient air and operate best in spaces that stay 40–120 °F, such as basements or large utility rooms. If gas is available, a condensing tank model can reach 96 % efficiency. During our visit we’ll evaluate venting, electrical capacity, condensate drainage, and available incentives to see whether an upgrade makes financial sense for your home.
