Pioneer Inverter Heat Pump 16.5kW for Pool 40 to 75m3

1. Description

We are proud to offer the new BWT Pioneer Inverter Horizontal range of 3 step inverter driven pool heat pumps

BWT are a leading heat pump manufacturer with a reputation for reliability

Inverter driven heat pumps allow the fan and compressor to be run at variable speeds from 25% to 100% depending on the load.

When initially turned on, the heat pump will run at 100% to bring the pool up to temperature.

Once the pool has reached the desired temperature, the inverter heat pump can then reduce and match its output to maintain the pool at the desired temperature.

The ability of the heat pump to be able to modulate its output to suit the demands of the pool can deliver significant cost savings.

  • Touch Screen Control Panel

6. What size heat pump do I require for my pool?

We have the following BWT  models available:-

ModelMax Power Output (KwRecommended Pool Size (m3)
CPIR088kw15-30 m3
CPIR109.5kw20-40 m3
CPIR1312.5kw25-45 m3
CPIR1716.5kw30-55 m3
CPIR2120kw35-65 m3


With inverter pool heat pumps, you should always over size the heat pump as much as possible.

Over sizing the heat pump allows the compressor to run at a reduced output (e.g. 25% to 50%) of its total power and this will then deliver the highest efficiency and the lowest running costs.
