Upgrade to Endless Hot Water for Your Snohomish County Home
A tankless water heater heats water on demand — no tank to fill, no standby heat loss, and no running out of hot water mid-shower. They use 20–30% less energy than traditional tank heaters, last twice as long, and take up a fraction of the space. Whether you're replacing an aging tank heater or building new, we'll help you choose the right unit for your household's needs and install it correctly — permitted, code-compliant, and backed by both the manufacturer warranty and our own labor warranty.

Frequently Asked Questions
How much does tankless water heater installation cost?
A typical tankless water heater installation in Snohomish County ranges from $2,500–$5,000 installed, depending on the unit size, fuel type (gas vs. electric), and whether gas line or electrical upgrades are needed. We provide free, detailed estimates so you know exactly what to expect.
What are the benefits of a tankless water heater?
Tankless water heaters provide endless hot water on demand, use 20–30% less energy than traditional tank heaters, last 20+ years (vs. 10–15 for tank heaters), and take up far less space. They also eliminate the risk of a tank rupture flooding your home.
How long does installation take?
Most tankless water heater installations are completed in one day. If gas line upgrades or electrical panel work is needed, it may take an additional day. We'll give you a specific timeline during your free estimate.
Do I need to upgrade my gas line for a tankless water heater?
Gas tankless water heaters require a larger gas supply than traditional tank heaters. We assess your existing gas line during the estimate and include any necessary upgrades in our quote. This is a common part of the installation process.
What size tankless water heater do I need?
Sizing depends on your household's peak hot water demand — the number of simultaneous fixtures running at once. We calculate the right flow rate and temperature rise for your home during the free estimate to ensure you never run out of hot water.
Are there rebates for tankless water heater installation?
Yes — Washington State utilities and the federal government currently offer rebates and tax credits for qualifying high-efficiency water heaters. We'll help you identify what you're eligible for during your estimate.
Do you install both gas and electric tankless water heaters?
Yes — we install both natural gas and electric tankless water heaters. Gas models typically provide higher flow rates and lower operating costs for most Snohomish County homes.
