Air to Water High Temperature Split Heat Pump & Combi Tank

A small heat pump with high performance

– Complete and integrated system

Enjoy twice the benefit with our two in one system with space heating and hot water supplied from one unit to ensure complete ease of installation and peace of mind.

– Space saving design

– Eco-friendly efficiency

High-performance heat pump technology keeps your home at a comfortable temperature even on the coldest days: down to -25c. At the same time, it reduces both domestic power use and CO2 emissions, and is compatible with solar panels.

Green R32 refrigerant helps keep your energy bills low as all our R32 range have highest possible A+++ energy ratings.

– Intuitive control from anywhere

The built-in controller has an LCD display and is easy to programme, giving you total control over the system from your utility cupboard; it’s also compatible with wireless thermostats.

The Hi-Kumo app turns your smartphone into a programmable remote control where you can adjust and monitor your heating system from anywhere in the world.
