This manual explains how to install and commission a Vent-Axia ground source heat pump.
The Vent-Axia Compact Single Compressor Heat Pump is designed to provide a low cost renewable heat
source for a buildings heating system. In addition, and if required, the Vent-Axia Compact can also provide
domestic hot water. Heat pumps can provide lower running costs and will generate significantly lower
carbon emissions compared with traditional fossil fuels.
The Vent-Axia Compact Single Compressor Heat Pump is designed for straightforward installation and re-
quires no specialist training to install. However the installation must conform to all relevant construction
and electrical codes and comply with the requirements of the Microgeneration Certification Scheme
(MCS) MIS3005 ’Requirements for Contractors undertaking the Supply, Design, Installation, Set to Work
