Water to Water Heat Pumps

Vortex Water to Water heat pumps use the stable ground temperature to produce useful hot water for Winter heating or cold water for Summer cooling.
  • energy efficient: clean, renewable energy from the ground plus electricity to achieve efficiencies equivalent to nearly 500% compared to electric baseboard
  • modular: use one for small buildings or multiples joined together for large buildings.
  • flexible: can be used for forced air heating/cooling, radiant infloor, domestic hot water, pool heating.  Alone or in all together.
  • Energy efficient: state of the art scroll compressors ... 
  • Quiet: state of the art scroll compressors and well insulated cabinets ensure whisper-quiet performance.

Each heat pump includes:
  • Energy efficient scroll compressor, pre-charged with environmentally friendly R410A refrigerant.
  • A pair of tubular heat exchangers to transfer energy between the ground and the building
  • A programmable controller for operation, status updates and troubleshooting.

Options available:
  • desuperheater with pump and control for high efficiency domestic hot water
  • advanced control with outdoor reset can boost efficiency by 20% or more
  • NPT or barbed water connections
  • Non-reversing models
  • Other voltages and 3 phase power available
  • Other capacities available

for compact & attractive installations
Single Stage
Energy efficient and low cost.
  • An excellent choice when matched to storage tank(s)

Two-Stage
A two-speed scroll compressor is used to boost overall efficiency
  • During periods of lower demand, the compressor runs at lower capacity but the full capacity of the heat exchangers are available to provide a higher efficiency as well as reducing the losses of frequent on/off cycles.
  • The advanced control only brings on second stage when operating time or temperatures require it.

Variable Capacity (Digital)
A precisely controlled scroll compressor is used to modulate between 10% and 100% capacity to precisely match the heating or cooling load.
  • Storage tanks can be eliminated to save space.
