Calor
Verde 'easy start' single phase heat pump
 At
last a heat pump that doesn't draw any more power to start than it does to run.
This means the Calor Verde heat pump can be installed for any pool with a normal
electricity supply. 'No need for three phase'.
These heaters are manufactured to the very highest standards,
smooth running, quiet and reliable.
They consume a fraction of the fuel that a conventionally
heated gas, oil or electric heater would thereby making a warm pool economically
viable. Pool heaters dramatically increase your swimming season and don't forget
that a heated pool could increase the season for rental holiday lets.

16Kw, single-phase and 23Kw to 30Kw three-phase - at

How do they work?
 Unlike conventional fossil-fuel-fired water heaters, Air to Water heat pumps
take heat from the surrounding air and transfer it to the water in the tank or
swimming pool. In a Calor Verde heat pump the heat exchanger is made of
titanium, which withstands the potential chemical and acid corrosion from
swimming pool water.

 Heat
pumps mainly consist of a compressor, fan, evaporator and the heat exchanger.
The compressor requires electricity to compress the refrigerant and vaporize it,
and the fan requires a small amount of electricity to continually blow air
across the evaporator coils when the unit is operating.
The only electricity cost is the operation of the compressor
and the fan in order to collect the free heat and pump it to the hot-water.
The heat pump works by taking heat from the surrounding air and using it to heat
low pressure liquid refrigerant in the heat pump’s evaporator, vaporizing the
liquid. The refrigerant then passes through the compressor, which raises the
refrigerant pressure and thus the temperature as well.
The heated refrigerant gas passes through the heat pump
condenser, where it gives off its heat to the water and condenses back into the
liquid state. The liquid refrigerant is now passed through an expansion valve where
the pressure is reduced and the cycle starts over.
