Tank Water Heaters Out, Dual NTi Wall-Mounted Boilers In

Two bulky tank water heaters. A cramped mechanical room. And a heating system that was running out of runway. That's what we were working with going into this job - a setup that had done its time but wasn't going to cut it moving forward.

We pulled both tanks out completely and stripped the room back to the framing. That mid-stage look is a little chaotic, sure - copper lines stubbed in, PEX runs staged, wiring coiled and waiting. But that's exactly where the planning pays off. Every connection point is thought through before anything goes back on the wall.

The finished install is a pair of NTi wall-mounted condensing boilers, side by side, copper piped with clean runs between them. Both units are mounted up off the floor, which is a big deal in a room this size. The floor space that those two tanks were eating up is now open. The system is also tied into the existing radiant distribution - you can see the PEX manifold lines running off to the right - so everything is working together as one integrated heating setup.

Wall-mounted boilers like these NTi units operate at high efficiency compared to older tank-style setups. They modulate their output based on demand, which means they're not burning fuel unnecessarily. And with two units installed, you've got built-in redundancy - if one ever needs service, the other keeps things running.

This is the kind of mechanical room upgrade that pays dividends for years. Cleaner, more efficient, better use of space - and a system that's actually built for the long haul.
