Second Hand Heat Siphon Z5.75hp50 29kw, Single Phase, Digital Controls Swimming Pool Heat Pump

We are selling a second hand Heat Siphon 29kw swimming pool heat pump.

Heat Siphon are made in the USA and are heat pumps with a reputation for reliability and raw output power. They are very well made and easy to maintain.

The heat pump was used to heat an outdoor pool of approximately 75m3 from May to September

It is a single phase model and requires a 32A Type-D circuit breaker to operate

It has been professionally maintained since new by HeatPumps4Pools – the leading supplier of swimming pool heat pumps.

The heat pump works well and there are no known faults.

It has worked reliably and heated the pool to 30c throughout the summer season (May-Sept)

It is in excellent condition and has always been properly winterised and covered during winter.

A FREE Winter cover will be supplied with the heat pump (worth £165)

We are selling the unit as it has been upgraded to an inverter heat pump by the owners.

The Heat Siphon heat pumps are for summer use (eg May-Sept) and require an air temperature of +10c and above to operate.

The unit is located in Ramsden Bellhouse, Essex, CM11 1RT

Inspection before purchase is welcome.

The heat pump can also be seen running if required.

Before the heat pump is shipped, it will be tested and checked.

It can either be collected or it can be packed in a wooden crate and delivered to a UK address on a pallet delivery service for £145

Note that if collecting this heat pump, you will need a tail lift vehicle as it is large and heavy and weighs approx 150kg

The heat pump has been fitted with a “soft-start” kit which helps to reduce the electrical spike when the compressor starts

It has a digital control panel to offer precise pool temperature control.

If you require any assitance to check the sizing of this unit for your pool, or have any questions about it, please call HeatPumps4Pools on 01268-206560
