Crawlspace water heaters are a headache. They're hard to access, they take up floor space, and when they start aging out, replacing them is a whole ordeal. That's exactly the situation we were working with here - two low boy units tucked into a crawlspace, both ready to be retired.
We swapped both of them out for a single wall-mounted Navien tankless unit. That's the key word - one unit doing the job of two. The Navien gets mounted directly to the wall, which clears up the floor area those old tanks were sitting on and makes future service calls a lot more manageable.
The other thing worth knowing about tankless water heaters is how they handle demand. Traditional tanks store a fixed amount of hot water. Once it's gone, you wait. A tankless unit heats water on the fly, so you're not dealing with that same limitation. For households where hot water runs out at the wrong time, that's a real quality-of-life upgrade.
The Navien line is Energy Star certified, which means it's not just convenient - it's also more efficient than a conventional storage tank. Over time, that tends to show up on your energy bill. It's one of those upgrades that makes sense both day one and in the long run.
If your current water heater is getting up there in age, or it's sitting somewhere that makes servicing it a pain, a tankless setup is worth having a conversation about. We install both gas and electric tankless systems and can walk you through what actually makes sense for your home.
