That is the situation where Thermo 2000’s 18 kW ComboMax Ultra 70 makes the most sense. Its T2 UltraSmart controller gives priority to domestic hot water, then returns to heating when the thermostat calls. According to the manufacturer, it delivers 87 US gal of hot water in 10 minutes and 175 US gal in one hour, for water at 110 °F, cold water at 40 °F and boiler water at 180 °F.\u003c\/p\u003e\n\u003ch3\u003eWhat is inside the unit\u003c\/h3\u003e\n\u003cp\u003eFour identical 4.5 kW elements, split over four stages, heat the 71 US gal of water in the tank up to 61,416 BTU\/h at 240 V. That water circulates in the heating loop to the radiators, hot-water baseboards or radiant floor. Parallel copper coils sit in the tank: drinking water flows through them and heats up on the way, without being stored. Thermo 2000 states that it arrives hot in under 7 seconds and that the absence of storage reduces the risk of Legionella. At the outlet, the pre-mounted thermostatic mixing valve tempers the water sent to the taps.\u003c\/p\u003e\n\u003ch3\u003eThe conditions to meet\u003c\/h3\u003e\n\u003cp\u003eThe unit draws 75 A at 240 V. Thermo 2000 specifies a 100 A breaker and Cu 4 or Al 2 wire, which assumes an electrical service with capacity to spare. At 208 V, output is multiplied by 0.75 and current by 0.867. Physically, the unit is 70 1\/2 in high and 24 in in diameter and weighs 430 lb empty: the basement stairs, the doors and the clearance under the beams matter as much as the floor space. Connections are 1 1\/4 in male NPT for heating and 3\/4 in female NPT for domestic water.\u003c\/p\u003e\n\u003ch3\u003eOur installation, from visit to start-up\u003c\/h3\u003e\n\u003cp\u003eFor a home in \u003cstrong\u003eMontreal\u003c\/strong\u003e, \u003cstrong\u003eLaval\u003c\/strong\u003e, \u003cstrong\u003eLongueuil\u003c\/strong\u003e, on the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e or the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e, it all starts with a free estimate.

The accessories supplied by Thermo 2000 (12 psi pressure regulator, check valve, automatic air vent, temperature and pressure gauge, 30 and 125 psi relief valves) are installed or already mounted. After the electrical connection, we fill and purge the loop, set the controller and test heating on all four stages, then hot water at several taps.\u003c\/p\u003e\n\u003cp\u003eAirGreen is a family business established in \u003cstrong\u003eMontreal\u003c\/strong\u003e for more than fifteen years, holding RBQ licence 5645-9605-01 (ventilation, refrigeration and electrical).
