Conforto’s brochure lists it under the code AT400010C15. It takes over where the AT3200 is no longer enough.\u003c\/p\u003e\n\u003cp\u003eIt is found in buildings that need a lot of heat: a \u003cstrong\u003eMontreal\u003c\/strong\u003e apartment building heated by a shared radiator loop, a \u003cstrong\u003eSouth Shore\u003c\/strong\u003e workshop or commercial space with a heated slab, a very large residence. It is also the option to consider when replacing an existing two-boiler electric system.\u003c\/p\u003e\n\u003ch3\u003eTwo boilers, one control logic\u003c\/h3\u003e\n\u003cp\u003eBoth units are AT series wall-mounted boilers of about 70 lb (32 kg) each as shipped, connected with 1 1\/4 in NPT fittings. Their controller works in stages, with element rotation, and its immersion sensor at the heat exchanger outlet prevents short cycling. It manages a heating setpoint and a domestic hot-water setpoint with priority for an indirect water heater, includes freeze protection and accepts a flow switch, a low-water device and a load-management input for the electricity provider.\u003c\/p\u003e\n\u003ch3\u003eElectricity and space, planned first\u003c\/h3\u003e\n\u003cp\u003eAt 40 kW, the building’s electrical service is the first issue to settle. Conforto publishes the electrical data of each of the two boilers, not of the complete system; we derive the supply required and compare it with the existing service before any recommendation. Wall space for two units and parallel piping must also be planned. Since no minimum flow is published for the whole, we check the loop against the requirements of each boiler.\u003c\/p\u003e\n\u003cp\u003eConforto’s limited lifetime warranty covers indoor residential use in Canada; for commercial use, the manufacturer provides 2 years on parts and 10 years on the heat exchanger. Yearly maintenance is required.\u003c\/p\u003e\n\u003ch3\u003eWhat AirGreen’s installation covers\u003c\/h3\u003e\n\u003cp\u003eWe start with a free on-site estimate, confirm the exact make-up of the system before ordering and give you a written quote that covers the boilers, the piping, the power supply and any upgrade needed. In an occupied building, we plan the draining steps with you to reduce the time without heat.\u003c\/p\u003e\n\u003cp\u003eOur technicians mount both boilers, make the connections, fill and purge the loop, commission the system and set the setpoints.
