It heats the water of a hydronic system with two 3,000 W elements that come on in two stages. When demand is low, a single element works; when the cold sets in, the second one joins it.\u003c\/p\u003e\n\u003cp\u003eThis size is meant for projects where the heating load stays modest. Think of a radiant floor in a finished basement, a room added at the back of the house, a workshop with a heated slab or a condo with hot-water radiators. Conforto presents the unit as a zero-emission solution, which makes it a consistent choice for a household that wants to heat its water with electricity.\u003c\/p\u003e\n\u003ch3\u003eHow it fits a Quebec home\u003c\/h3\u003e\n\u003cp\u003eThe AT0623 mounts on the wall, which keeps the mechanical room floor clear. It weighs about 70 lb (32 kg) as shipped and connects to the loop through 1 1\/4 in NPT fittings. Conforto designs it for low-temperature radiant heating as well as high-temperature hot-water baseboards and radiators.\u003c\/p\u003e\n\u003cp\u003eOn the electrical side, it needs a 240 V single-phase supply, with a minimum circuit ampacity of 38.8 A and maximum protection of 40 A. That is the lowest electrical demand in the AT series, an advantage when you add hot-water heating to only part of the house and the panel has little room left.\u003c\/p\u003e\n\u003cp\u003eThe controller brings two practical advantages. An immersion sensor at the heat exchanger outlet prevents short cycling, and a separate setpoint lets you make domestic hot water with an indirect water heater, with priority over space heating. A load-management input also lets the electricity provider control the unit.\u003c\/p\u003e\n\u003ch3\u003eWhat AirGreen’s installation covers\u003c\/h3\u003e\n\u003cp\u003eEverything starts with a free on-site estimate.
