The manufacturer presents it as the only high water volume electric boiler on the market and designs it for a specific role, as the backup source of a renewable-energy heating system. Geothermal, an air-to-water heat pump or solar collectors handle most of the heating; the AltSource tops it up.\u003c\/p\u003e\n\u003cp\u003eIn this size, the electric side is deliberately small. A single 4.5 kW element, in a single stage, delivers 15,354 BTU\/h at 240 V. It is the leanest combination of the AltSource 70: this model’s full water reserve for the lowest current draw.\u003c\/p\u003e\n\u003ch3\u003eThe homes where this size makes sense\u003c\/h3\u003e\n\u003cp\u003eThis size suits owners who have invested in a well-sized renewable source and want a discreet electric backup.

At 208 V, output drops to 3.4 kW (16.3 A). The T2 UltraSmart controller, supplied with its outdoor sensor, modulates output and water temperature to the weather, shuts heating off in warm weather and offers a Boost mode.\u003c\/p\u003e\n\u003ch3\u003ePreparing the location\u003c\/h3\u003e\n\u003cp\u003eA 71 US gal reserve takes up space and weight. The unit measures 24 in in diameter and 28 in deep with the door, and weighs 380 lb before the water is added. We check the access path to the mechanical room and the strength of the floor. The loop connects through 1 1\/4 in male NPT fittings and operates at a maximum pressure of 30 psi. For the expansion tank, Thermo 2000 recommends a #60 with baseboards or a radiant floor, and a #90 with cast-iron radiators.\u003c\/p\u003e\n\u003cp\u003eIf you also want to preheat domestic water, Thermo 2000 offers an optional 26.2 sq ft parallel copper coil heat exchanger.
