Catalina 4kW Eco Hot Tub Heat Pump
Catalina Spas 4kW Eco Heat Pump
These 4 kW heat pumps can potentially turn 1kW of electricity into 4kW’s of heat and will substantially reduce heating costs.
How do they work?
A heat pump is a machine or device that moves heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat sink') at a higher temperature. They work by exploiting the physical properties of an evaporating and condensing fluid known as a refrigerant
The working fluid, in its gaseous state, is pressurised and circulated through the system by a compressor. On the discharge side of the compressor, the now hot and highly pressurised vapor is cooled in a heat exchanger, called a condenser, until it condenses into a high pressure, moderate temperature liquid. The condensed refrigerant then passes through a pressure-lowering device called an expansion valve. The low pressure, liquid refrigerant leaving the expansion device enters another heat exchanger, the evaporator, in which the fluid absorbs heat and boils.The refrigerant then returns to the compressor and the cycle is repeated.
Since the heat pump or refrigerator uses a certain amount of work to move the refrigerant, the amount of energy deposited on the hot side is greater than taken from the cold side.
What is COP?
Coefficient of Performance is the amount of heat moved per unit of input work required. A typical electric resistance heater has a COP of 1.0. That is, one joule of electrical energy will cause a resistance heater to produce one joule of useful heat, while under ideal conditions, one joule of electrical energy when used for heating a Swimspa or Spa on a mild day of say 10 °C, a Catalina ECO heat pump has a COP of between 3 and 4 and up to 6.8 at 25 °C
The heat pump does not include connection pipe work or fittings. These can be purchased by selecting the 'Heat Pump Fitting Kit'. The Heat Pump Fitting Kit includes 5 metres of plumbing, an auxiliary heat controller and a changeover switch.
