The Conforto AT2045 delivers 20 kW at 240 V, or 68,200 BTU\/h according to the manufacturer, while remaining a wall-mounted unit of about 70 lb (32 kg) as shipped.\u003c\/p\u003e\n\u003cp\u003eIts four 5,000 W elements come on one by one, in four stages, and the controller alternates the one that starts first. An immersion sensor at the heat exchanger outlet controls the stages and prevents short cycling.\u003c\/p\u003e\n\u003ch3\u003eResidential or commercial use: what Conforto provides\u003c\/h3\u003e\n\u003cp\u003eConforto’s limited lifetime warranty covers indoor residential use in Canada: 5 years on the heat exchanger and the components installed by the manufacturer, then the heat exchanger at no charge for the first 20 years and prorated after that. For commercial use, the manufacturer provides 2 years on parts and 10 years on the heat exchanger. In both cases, yearly maintenance is required, and labour and shipping are excluded.\u003c\/p\u003e\n\u003ch3\u003eHow it fits the building\u003c\/h3\u003e\n\u003cp\u003eThe starting point is electricity. Conforto lists a minimum circuit ampacity of 111.7 A and maximum protection of 125 A, at 240 V single phase. In a plex or a commercial space, the electrical service already serves many other loads: we assess it before recommending this size, and the quote clearly states whether an upgrade is needed.\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 6.8 gpm for a 20 °F ΔT. The controller manages a heating setpoint, a domestic hot-water setpoint with priority for an indirect water heater, freeze protection, and inputs for a flow switch, a low-water device and load management by the electricity provider.\u003c\/p\u003e\n\u003ch3\u003eWhat AirGreen’s installation covers\u003c\/h3\u003e\n\u003cp\u003eWe come out at no charge for the estimate, then give you a written quote that details the boiler, the circulator and the loop components. At installation, our technicians mount the boiler, connect it, fill and purge the circuit, check the four stages and set the setpoints. In an occupied plex, we plan the work with you to limit the time without heat, and we explain the yearly maintenance to the person who will look after the building.
