Crystal Enterprises Heat Pump *13Kw*













Do not let the price of this product fool you, they are quality. Our heater pumps can be used both in the Summer and Winter seasons, as they are fitted with "Auto-Defrost System" (see PDF specs sheet) but must be sited outside.

**NEW for 2015**

Crystal Enterprises Heat Pump

Heating/Cooling Auto Conversion Kits.



Crystal Heat pumps can now be converted to operate automatically, switching between  heating  or cooling as necessary.

 This is ideal for Polytunnel users and pond applications.


 For example,  

            1) A customer in Cornwall was using a Polytunnel  as his pool enclosure, his pool water achieved 40 degrees during summer. This will have degraded his liner and would lead to the liner requiring replacement much earlier than necessary. If the customer had our heat pump auto conversion kit on his heat pump, the heat pump would have sensed that the water was higher than the set parameters and switched  into cooling mode automatically. Therefore holding and maintaining the water at the desired temperature.


            2) A  pond customer, whilst  working in the Hydroponics field, lost all his fish due a detrimental temperature rise in the water.

In this situation, during the summer, the pond could potentially over heat and kill the fish.

If one of our heat pump auto conversion kits were fitted, this would enable a more stable temperature to be maintained with a differential of 3 degrees (1.5 degrees either side of the desired temperature).


Crystal  Auto Conversion Kits are available on request at a cost of

                                                 £125 plus delivery.

These conversion kits can be applied to all Crystal Heat Pumps young or old across all models.

The kit should to be fitted by a competent / qualified person.

It is strongly recommended that the heat pump is checked periodically at times of extreme temperatures due to possible unforeseen circumstances.
