Tankless Water Heater Murrieta | Williams Mechanical Co
Murrieta is one of the fastest-growing cities in Riverside County, and a lot of those newer homes were built with standard tank water heaters that are already due for an upgrade. Williams Mechanical Co installs Navien, Noritz, and Rinnai tankless systems throughout Murrieta — handling everything from the gas line conversion to venting, permits, and final inspection. One crew, one call, done right.
Frequently Asked Questions
How much does tankless water heater installation cost in Murrieta?
A full conversion with the Noritz EZTR40 — a Japanese-made all-in-one kit with venting included — runs around $5,000 installed. Murrieta homes built after 2000 typically have adequate gas lines already, which keeps the overall cost down. Free estimates and Wisetack financing available.
How long does a tankless water heater conversion take in Murrieta?
Most conversions are completed in one to two days. The Noritz EZTR40 is an all-in-one replacement kit so we're not sourcing separate venting components — cleaner install, less time on site. If you need hot water during the conversion, we offer rental water heaters so you're never without.
What if my furnace shares a vent with my water heater?
This comes up in some older Murrieta homes. When the furnace and water heater share a flue, the tankless unit needs its own dedicated vent run. In that case the Navien NPE is often the better fit since it uses smaller PVC exhaust.

Why Choose Williams Mechanical Co

Serving Riverside and San Diego
Murrieta's rapid growth over the last two decades means most homes here were built between 1995 and 2015 — a sweet spot for tankless conversions. The gas infrastructure is typically newer and sized appropriately, and the venting situations are usually straightforward. Williams Mechanical Co regularly works in Murrieta and knows the permitting process through the city well.
Federal Tax Credit
Many high-efficiency tankless water heaters — including qualifying Navien and Noritz models — may be eligible for a federal energy efficiency tax credit of up to 30% under the Inflation Reduction Act. This could put up to $1,500 back in your pocket. We recommend consulting your tax professional to confirm eligibility.
