The Conforto AT1644 answers with 16 kW at 240 V, or 54,600 BTU\/h according to the manufacturer, in a wall-mounted format.\u003c\/p\u003e\n\u003cp\u003eIts four 4,000 W elements come on one by one, in four stages, with element rotation. The boiler keeps a gradual response: one element in mild weather, all four in deep cold. An immersion sensor at the heat exchanger outlet prevents short cycling.\u003c\/p\u003e\n\u003cp\u003eIn the AT series, only the AT2045 and the AT2446 go further as a single boiler; beyond that, Conforto offers systems of two boilers installed in parallel. The AT1644 therefore holds a pivotal place for large homes.\u003c\/p\u003e\n\u003ch3\u003eElectricity first, water next\u003c\/h3\u003e\n\u003cp\u003eAt this output, the electrical service often decides the project. Conforto lists a minimum circuit ampacity of 90.8 A and maximum protection of 100 A, at 240 V single phase. Before recommending the AT1644, we therefore look at your panel and everything already connected to it, then put it in black and white in the quote.\u003c\/p\u003e\n\u003cp\u003eOn the water side, the boiler connects with 1 1\/4 in NPT fittings and requires a minimum flow of 5.5 gpm for a 20 °F ΔT. The controller accepts a flow switch and a low-water device, includes freeze protection and shows its values on a 3-character LED display. It also manages a separate domestic hot-water setpoint, with priority, if you add an indirect water heater, and a load-management input for the electricity provider.\u003c\/p\u003e\n\u003cp\u003eBeing wall-mounted, it weighs about 70 lb (32 kg) as shipped, which leaves the floor free for the water heater and piping.\u003c\/p\u003e\n\u003ch3\u003eWhat AirGreen’s installation covers\u003c\/h3\u003e\n\u003cp\u003eWe start with a free in-home estimate: electrical panel, existing loop, emitters, location. You then receive a written quote that states the boiler, the circulator and the other components to plan for.\u003c\/p\u003e\n\u003cp\u003eOn installation day, our technicians mount the boiler, connect it to the piping and the electrical circuit, fill and purge the loop, then check that all four stages work.
