Although it may look like the control panel for a radiant heating system, the Radiant Ready 30E is actually the entire mechanical room — boiler, manifold, pump, expansion tank, valves, thermostat, and air vent — all preassembled in a unit that you hang on the wall and then plumb and wire. It can heat up to 2,000 square feet, the maker says, and comes equipped with a five-loop manifold that can be customized to receive up to three more loops. It costs about $6,000.
