HOTJET ZETXe – outdoor inverter monoblock
Our best-selling series. The ZETXe sits outside, connects to the house with two pipes and one cable – and heats. The inverter adjusts output smoothly to match demand, so the unit never runs at full power unnecessarily.
The standard configuration controls up to 3 circuits (heating, cooling, DHW). Copeland scroll compressor with variable speed.
Why ZETXe
- Inverter regulation – smooth operation, lower consumption, longer compressor life
- 3 circuits included – heating, cooling and hot water at no extra cost
- Cascade – need more output? Connect multiple units together
- Active noise suppression – noise reduction system for peaceful neighbourhood
- Reverse cycle defrosting – efficient and fast

ZETXe vs. ZETXi
ZETXe (External) sits outside. ZETXi (Internal) is installed indoors with air supplied through ducts. Technically identical – they differ only in installation method. ZETXi is quieter for the surroundings, ZETXe takes up less space inside.
