West Valley Home Gets a Navien Tankless Water Heater Upgrade

Here's what we were working with - an aging 40-gallon tank water heater crammed into a tight utility space. It was doing its job, but just barely. Tank heaters like this one work by keeping a full supply of water hot around the clock, whether you're using it or not. That constant energy draw adds up, and when the tank finally starts to go, you're left with lukewarm showers and a puddle on the floor.

We pulled out the old tank and got to work setting up the new Navien unit. The difference in footprint alone is significant. Once the old heater was out, that utility space opened up considerably. With a tankless system wall-mounted like this, the floor space that used to be occupied by a bulky tank is freed up entirely - a small but real win for any utility room.

The Navien went in clean. We ran new PVC venting through the top, tied in the gas line, and added an expansion tank as part of the install. That expansion tank is worth noting - it's a code requirement in closed plumbing systems and helps protect your pipes and fixtures from pressure fluctuations. It's the kind of detail that keeps the system running right for years down the road.

On-demand water heating is the main selling point here. Instead of keeping 40 gallons hot all day, the Navien only fires up when you actually turn on the hot water. You get hot water when you need it, and you stop paying to keep a tank warm when you don't. For most households, that's a meaningful improvement in efficiency.

If your tank water heater is getting up there in age, it's worth knowing what your options look like. A tankless setup isn't right for every home, but for a lot of homeowners in West Valley and across Utah, it makes a lot of sense. We're happy to walk through the details with you.
