The \u003cstrong\u003eThermo 2000 DoubleMax 50-4 indirect water heater\u003c\/strong\u003e brings the two functions together: the boiler heats the house and produces hot water through a \u003cstrong\u003edouble-wall copper heat exchanger\u003c\/strong\u003e housed in a \u003cstrong\u003e50 US gallon\u003c\/strong\u003e tank. AirGreen installs it in \u003cstrong\u003eMontreal\u003c\/strong\u003e, \u003cstrong\u003eLaval\u003c\/strong\u003e, \u003cstrong\u003eLongueuil\u003c\/strong\u003e, on the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e and on the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt is the format that best suits a typical single-family home: enough reserve for a family, a 22 in diameter that slips in beside the boiler and an output that depends directly on the boiler’s capacity.\u003c\/p\u003e\n\n\u003ch3\u003eHow an indirect water heater works\u003c\/h3\u003e\n\u003cp\u003eThe DoubleMax heats water from the boiler: hot water from the boiler circulates through copper piping wound in \u003cstrong\u003eparallel helicoidal lines\u003c\/strong\u003e inside the tank, then returns to the boiler. It transfers its heat to the potable water without ever mixing with it. When the water in the tank cools, the control calls for heat from the boiler, which feeds the exchanger until the set point is reached. AirGreen installs this tank with an \u003cstrong\u003eelectric boiler\u003c\/strong\u003e, on a zone dedicated to domestic hot water.\u003c\/p\u003e\n\n\u003ch3\u003eWhy a double-wall heat exchanger\u003c\/h3\u003e\n\u003cp\u003eIn an ordinary coil, a single thickness of metal separates the heating water from the water you drink. The DoubleMax uses two: the exchanger’s copper piping is \u003cstrong\u003edouble-wall\u003c\/strong\u003e. This extra barrier is sought after when the heating water contains an additive, such as antifreeze, or when an engineer or inspector requires double separation. Thermo 2000 also states that the copper components meet the low lead requirements for potable plumbing products and the \u003cstrong\u003eNSF 61\u003c\/strong\u003e standard.\u003c\/p\u003e\n\n\u003ch3\u003eManufacturer’s data\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eCapacity:\u003c\/strong\u003e 50 US gallons\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHeat exchanger:\u003c\/strong\u003e double-wall copper, exchange surface of 24.7 sq. ft.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMaximum domestic hot water flow:\u003c\/strong\u003e 12 gpm (value to be reduced for high-temperature and continuous-flow applications)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMaximum pressure:\u003c\/strong\u003e 150 psi\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBoiler connection:\u003c\/strong\u003e 1 1\/4 in NPT male\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDrain valve:\u003c\/strong\u003e ¾ in brass ball valve, maximum working pressure of 150 psi\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e height 59 1\/4 in, diameter 22 in\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 260 lb (330 lb shipping)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eReading the output table by boiler capacity\u003c\/h3\u003e\n\u003cp\u003eThermo 2000 publishes the output of the DoubleMax 50-4 according to boiler capacity, for cold water at 40 °F and boiler water at 180 °F. Each value reads in two parts, as first hour \/ continuous, in US gallons per hour. The first two lines of the table are those closest to a residential electric boiler:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e50,000 BTU\/h (15 kW) boiler:\u003c\/strong\u003e 136 \/ 86 US gallons for water at 110 °F; 80 \/ 60 at 140 °F; 69 \/ 60 at 160 °F.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e100,000 BTU\/h (29 kW) boiler:\u003c\/strong\u003e 222 \/ 172 US gallons at 110 °F; 140 \/ 120 at 140 °F; 129 \/ 120 at 160 °F.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 110 °F column corresponds to the mixed water coming out of a shower; the 140 °F column to hotter stored water, then brought back to a safe temperature by a mixing valve. The effect of the boiler is clear right away: doubling its capacity clearly increases continuous output, while the tank volume stays the same.\u003c\/p\u003e\n\n\u003ch3\u003eChoosing the electric boiler capacity\u003c\/h3\u003e\n\u003cp\u003eAn electric boiler is sized first for heating the house. If it must also produce hot water, we check that its capacity gives enough output at peak times and we usually program \u003cstrong\u003ehot water priority\u003c\/strong\u003e: for a few minutes, the boiler devotes itself to the tank, then returns to the rooms. Thanks to the thermal mass of the radiant floor or radiators, this short detour is rarely felt in the house. The electrical service, the panel capacity and the circuit gauge are part of this check.\u003c\/p\u003e\n\n\u003ch3\u003eWho the DoubleMax 50-4 is for\u003c\/h3\u003e\n\u003cp\u003eThis model suits a family of three or four with one or two bathrooms, in a home already equipped with an electric boiler. It also suits new construction where radiant floors are planned from the start, or the replacement of an old indirect tank. For a home with a large tub or several simultaneous showers, a larger DoubleMax offers more reserve; we compare the formats during the assessment.\u003c\/p\u003e\n\n\u003ch3\u003eLocation and connections\u003c\/h3\u003e\n\u003cp\u003eAt 59 1\/4 in high and 22 in in diameter, the tank fits beside the boiler in most basements. The boiler connection is 1 1\/4 in NPT male; the size of the potable water connections is confirmed with the manufacturer’s sheet at the quote stage. The brass ball drain valve makes yearly maintenance easier. The 260 lb weight, plus that of the water, requires a solid, level floor, ideally near a drain.\u003c\/p\u003e\n\n\u003ch3\u003eManufacturer’s warranty\u003c\/h3\u003e\n\u003cp\u003eThermo 2000 distinguishes residential and commercial use.
