The \u003cstrong\u003eThermo 2000 DoubleMax 80-5 indirect water heater\u003c\/strong\u003e relies on the home’s \u003cstrong\u003eelectric boiler\u003c\/strong\u003e to heat an \u003cstrong\u003e80 US gallon\u003c\/strong\u003e tank through a 30.9 sq. ft. \u003cstrong\u003edouble-wall copper heat exchanger\u003c\/strong\u003e.

In a home where two generations live under one roof, morning showers, the dishwasher and the washing machine add up. A family of five with a large freestanding tub is another typical example. For a more modest home, a smaller tank from the same series is often enough; we make the comparison with you during the visit.\u003c\/p\u003e\n\u003cp\u003eThis tank works with an electric boiler already in place or installed at the same time, as part of a radiant floor project or the replacement of an old heating system.\u003c\/p\u003e\n\n\u003ch3\u003eManufacturer’s data\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eCapacity:\u003c\/strong\u003e 80 US gallons\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHeat exchanger:\u003c\/strong\u003e double-wall copper piping in parallel helicoidal lines, exchange surface of 30.9 sq. ft.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMaximum domestic hot water flow:\u003c\/strong\u003e 15 gpm, 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\/2 in NPT male\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDrain valve:\u003c\/strong\u003e ¾ in brass ball valve, 150 psi maximum\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e height 73 3\/4 in, diameter 24 in\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 355 lb (440 lb shipping)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCompliance:\u003c\/strong\u003e copper components meet the low lead requirements and the NSF 61 standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe reserve fills the tub, the boiler handles the rest\u003c\/h3\u003e\n\u003cp\u003eThermo 2000’s values read as \u003cstrong\u003efirst hour \/ continuous\u003c\/strong\u003e, in US gallons per hour, with cold water at 40 °F and boiler water at 180 °F. The gap between the two figures shows the role of the tank. With a 50,000 BTU\/h (15 kW) boiler, the DoubleMax 80-5 delivers 166 \/ 86 US gallons at 110 °F: the first hour is much more generous than the continuous rate, because the 80 US gallons already hot add to what the boiler produces during that time.\u003c\/p\u003e\n\u003cp\u003eThat is exactly what a large tub needs. It fills from the stored water, in a few minutes, without waiting for the boiler.

We start from that capacity to tell you what the DoubleMax 80-5 will really deliver, rather than quoting the most flattering line of the table. If a gap remains between your needs and the expected output, we discuss it before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eA double-wall copper heat exchanger\u003c\/h3\u003e\n\u003cp\u003eThe DoubleMax exchanger is made of \u003cstrong\u003edouble-wall\u003c\/strong\u003e copper pipes, wound in parallel helicoidal lines. Two thicknesses of metal separate the boiler water from the potable water. This design is valued when the heating water contains an additive such as antifreeze, or when the inspection requires double separation. The copper components meet the NSF 61 standard and the low lead requirements for potable water.\u003c\/p\u003e\n\n\u003ch3\u003eA tall tank: check the free height\u003c\/h3\u003e\n\u003cp\u003eThe DoubleMax 80-5 is 73 3\/4 in high and 24 in in diameter. It is a slender format that takes little floor space but requires enough free height under the joists, ducts and piping, not forgetting the space needed above for the fittings. We measure the mechanical room or basement before confirming the model. The tank weighs 355 lb, plus the weight of the water: it must sit on a solid, level floor, near a drain.\u003c\/p\u003e\n\n\u003ch3\u003eControls, priority and temperature\u003c\/h3\u003e\n\u003cp\u003eThe tank control is connected to the electric boiler, usually with \u003cstrong\u003ehot water priority\u003c\/strong\u003e. The boiler connection is 1 1\/2 in NPT male; the size of the potable water connections is confirmed with the manufacturer’s sheet at the quote stage. If you choose to store water at 140 °F or more, a \u003cstrong\u003ethermostatic mixing valve\u003c\/strong\u003e brings the water delivered to the taps back to a safe temperature. According to Thermo 2000, the 15 gpm maximum flow must be reduced for high-temperature and continuous-flow applications; we take this into account when choosing the piping.\u003c\/p\u003e\n\n\u003ch3\u003eManufacturer’s warranty\u003c\/h3\u003e\n\u003cp\u003eIn \u003cstrong\u003eresidential use\u003c\/strong\u003e, Thermo 2000 provides a \u003cstrong\u003e15-year warranty\u003c\/strong\u003e on the tank and copper coils.
