Old Tank Water Heater Swapped for Dual Rinnai Tankless Units in West Linn

Here's what we were working with - an aging A.O. Smith ProMax tank unit taking up a significant chunk of floor space in a utility room that was already pretty packed. It had done its job, but tank water heaters have a shelf life, and this one was at the point where the homeowner was better off replacing it than waiting for a problem to show up at the worst possible time.

We pulled the old tank and installed two Rinnai RXP199 tankless units mounted side by side on the wall. Running them in tandem like this gives the home serious hot water capacity - enough to handle multiple fixtures or appliances drawing at the same time without any drop in performance. That's the kind of reliability a busy household actually needs.

The difference between a tank and a tankless setup comes down to how they work. A traditional tank constantly heats and reheats a stored supply of water, burning energy whether you're using it or not. A tankless unit only fires when hot water is actually called for. That means no standby heat loss, a smaller footprint, and hot water that doesn't run out mid-shower.

What you're looking at with the RXP199 is one of the more capable residential tankless units on the market. The internal heat exchanger and condensing technology are built to squeeze maximum efficiency out of every BTU. Both units are tied into the home's copper supply lines with clean, organized connections - nothing rushed or sloppy about the install.

If your current water heater is getting up there in age or you're constantly running out of hot water, a tankless upgrade is worth looking into seriously. It's one of those home improvements that pays you back in comfort and lower energy costs for years down the road.
