Heat Pump (UniChiller)
 
Conventional methods dictate that in order to heat or cool a house, an electric or gas powered furnace and/or an air conditioner is required. These traditional methods are expensive to purchase/install, expensive to maintain and generally occupy a large amount of surface area. However, a new and innovative method has been developed. Known as the heat pump (UniChiller), it is a revolutionary heating and cooling unit for the home. It is able to combine the benefits of the traditional furnace and the air conditioner into one central system which acts as both to heat and/or cool your home. The heat pump illustrates green credentials by offering a 3.0 or better under normal operating circumstances. In other words, for every dollar spent on energy to run the system, the return is $3 worth of heating for your Vancouver household. The installation ends up paying for itself, eventually making your investment back in approximately 5 years.

The heat pump is installed outside and comes fully charged for life with a sealed refrigerant circuit. It is able to withstand the cold mountainous climate of North and West Vancouver. As well, no hazardous material is sent into the household, only water is pumped to and from the building. The pump is made from stainless steel and weathering is kept to a minimum. As well, no maintenance is necessary for the refrigeration circuit and the life expectancy for the system is approximately 20-25 years.

The Heat pump provides both hot and cold water for central heating and/or cooling. In the winter time usable heat is captured by the outdoor heat exchanger and this heat is sent via refrigerant lines to an indoor "A" Coil which is attached to the plenum of your furnace. In the summer the system is reversed and heat in your home is captured by the "A" Coil and sent to the outside heat exchanger to be expelled.

Positives:

  • The Unichiller is a self-contained and pre-charged air-to-water heat pump
  • The UniChiller functions fairly quietly (66 dB) by using fans with a swept-wing configuration
  • The UniChiller can be banked alongside other UniChiller to increase capacity and provide redundancy for increased reliability
  • No maintenance necessary with life expectancy of 20-25 years
  • It is Fairly easy to install, comes factory charged and never requires further charging
  • It can be placed at a remote location with properly sized piping and pumps (up to 300ft)
  • Available only with R-407C (ozone friendly) refrigerant
  • There are no freeze-up problems caused by partial load conditions
  • Requires very low power to operate resulting in substantial savings on hydro bills
