Wall-Hung NTI Boiler Install with Radiant Manifold and Indirect Tank

Small mechanical rooms are some of the trickiest spaces to work in. You've got limited floor space, tight corners, and a long list of components that all need to fit together cleanly - without the whole thing looking like a mess of pipes going nowhere.

Here's what we packed into this one: a wall-hung NTI boiler, an NTI V-Series indirect tank for domestic hot water, four Taco zone valves, and a full radiant heating manifold with multiple circuits. Every run of copper was planned out deliberately so the space stays accessible and the system stays serviceable down the road.

The radiant manifold is really the heart of this setup. Each circuit gets its own zone valve, which means different areas of the home can be heated independently. That kind of control is a big deal - you're not heating rooms you're not using, and you're not fighting with a single thermostat trying to keep everyone comfortable. Radiant heat itself is quiet, even, and efficient. No forced air, no cold spots, no noise.

The NTI indirect tank ties directly into the boiler, using it as the heat source for domestic hot water instead of running a separate water heater. That's a smarter, more efficient approach - especially when you already have a high-efficiency condensing boiler doing the heavy lifting. One heat source, two jobs done well.

Tight space or not, a clean install is always the standard. Copper piping run straight, components mounted properly, and a system that's built to be understood by whoever works on it next. That's what good mechanical work looks like.
