Water Heater Installation & Replacement

Traditional Tank Water Heaters

These heaters store and heat a large volume of water in a tank, keeping it ready for use. While affordable, they consume energy throughout the day, even when not in use.

Tankless Water Heaters

Also known as on-demand water heaters, these systems heat water only when you need it. Tankless water heaters save energy, reduce utility bills, and provide unlimited hot water, a modern solution for many Kirkland homes.

Whether you need tankless water heater repair or are considering switching from a tank system, our expert technicians can guide you through the right choice for your home.

Frequently asked questions

Do I need a permit to replace a water heater in Kirkland, WA?

Yes – Washington State requires a plumbing permit for every water heater replacement, and the City of Kirkland Development Services issues them for addresses within Kirkland city limits. Skipping the permit can result in fines, void your equipment warranty, and create problems when you sell your home. When you book with Green House Plumbing, we handle the entire permit process – application, inspection scheduling, and code compliance – so you don’t have to lift a finger.

Which water heater brands do you install in Kirkland?

We install and service all major brands in Kirkland, including A.O. Smith, Bradford White, Rheem, Rinnai, Navien, and Noritz – covering both traditional tank and tankless systems, as well as heat pump water heaters. Our technicians are trained across all these product lines and can recommend the right brand and model based on your home’s square footage, water usage, and whether you’re a PSE customer eligible for rebates on specific models.

How long does water heater installation take in Kirkland?

A standard tank-to-tank replacement in a typical Kirkland home takes 2–4 hours from arrival to cleanup. Upgrading to a tankless system takes longer – usually 4–8 hours – because it often involves rerouting gas lines, upgrading venting, or adding an electrical circuit. We aim to have your home back to full hot water the same day we arrive.

When should I replace rather than repair my water heater in Kirkland?

The general rule: if your unit is under 8 years old and the issue is minor, repair is usually more cost-effective. If it’s 10–12 years or older, frequently breaking down, or struggling to meet your household’s demand, replacement is the smarter long-term choice – especially given Kirkland’s available PSE rebates on energy-efficient replacements. Our technicians will give you an honest assessment with no pressure either way.
