climate heat pumps are a revolution in heat pump technology and remain
unmatched in cost and performance. Our engineers designed this heat pump on a
mission to make it the most efficient cold climate heat pump on the market at ½
the price of a traditional geothermal heat pump. This is done without
sacrificing quality. The design of the unit calls for the use of
industry-leading components. This includes variable speed pumps, Panasonic EVI
DC inverter compressors, European Sanhua valves and Chico digital control
systems. All of this is utilized directly into the complete weatherproof
Integrated heating solutions
any other cold climate heat pump system on the market, our cold climate heat
pumps control your entire home heating and cooling needs, including domestic
hot water. Heat pumps integrate multiple heat sources such as: radiant floor
heating/cooling, forced air central Air handlers, split fan coils for
individual room heating, low temperature radiators, and can also be integrated
into any swimming pool or hot tub to provide full heat through our titanium
heat exchangers. The Outdoor Unit (ODR) contains everything you need in one
case (one piece). This results in no need to hire a refrigeration mechanic. All
you need is an electrical connection with an outdoor rated disconnect (weather
proof). The system requires a 240 VAC connection and dedicated circuit breakers
for 20, 30, 40 amps, depending on the size of the cold climate heat pump.
backup heating circuit in the buffer tank can be automatically controlled by
the heat pump itself, and the integration with the internal heater is simple
and effective. The backup heater will only receive a signal from the cold
weather heat pump if the heat pump can't keep up. This ensures that you never
waste energy with two heat sources competing. Our buffer/boiler tanks are
designed specifically for our cold weather heat pumps and include additional
features like extra insulation and an internal port for temperature probes for
more accurate temperature readings. The range of these tanks forms 4-29 kW.
of separating our products into 5 or 6 sizes, our technology allows us to
combine heat pumps together to form larger heating systems as needed. With our
MX controllers you can add up to 10 heat pumps. Our design works in parallel so
each unit has its own pump, but the controller will manage all the heat pumps
as if they were one large heat pump.
other cold weather heat pumps that require direct communication with each zone,
our heat pump uses simple differential controller logic that incorporates tank
thermometer probes. Our tanks have a special copper probe port insert on the
top and bottom so we can measure the tank accurately. The heat pump will
automatically optimize to reach the design temperature set for the tank. As the
weather changes, so does the heat pump, using only what is needed to keep the
buffer tank at the set temperature. It can do this by changing the frequency of
its DC inverter compressor to increase or decrease power as needed.
does it work?
plant controller systems can manage heating or cooling or both at the same
Heating and cooling
domestic hot water (with optional internal HX coil)
set up the heat, the heat pump will turn on and start the circulation pump and
heat the buffer tank unit to the desired set point temperature. The cooling is
the same, the only difference is that the buffer tank is a special foam tank
that is designed not to sweat and condense, and the heat pump will shut off
when the buffer tank reaches its set low temperature.
also set heating and cooling at the same time, for example in summer when you
want to cool the house and heat domestic hot water. In this case we use the
optional internal HX in the buffer tank. It is 160 feet of copper and is
capable of 94-97% efficiency. In this mode (heating and cooling) our heat pump
will first heat the hot water buffer tank to ensure there is hot water, then it
will activate a 3-way valve and switch to the cooling tank and reverse its
function to cooling. If domestic hot water is not needed in summer, heating and
cooling can be done on one tank.
system is best for an air-to-water heat pump?
most geothermal installations, we use R410a Eco Freon, the properties of this
refrigerant fluid produce a maximum design temperature of 60C (140 F). However,
we recommend system design temperatures below 51C (125F) to maximize heat pump
performance. Therefore, radiant floor heating is an important source of heat
for our ATW heat pumps. However, we also offer freestanding wall mounted fan
coil units for room zoning. These special circulating fan coil units are
designed to provide both heating and cooling in the 110-120 F water supply
temperature range. For central heating and cooling our Hydronic Air Handlers
for Heat Pumps are a perfect match for air-to-water heat pumps as they feature
a specially designed 6-layer heat exchanger optimized for excellent performance
at 120 F or lower .
The transmitter is not intended for use with heat pumps. Older technology air
handlers require higher design temperatures, and cast iron boilers cannot
operate at lower design temperatures.
