Connecting the heat pump to the heating system

Care should be taken to avoid excessive use of flux on copper pipe connections to minimise the amount of debris that the filter can come into contact with.

System flushing and care

Central heating systems must be power flushed before the heat pump is installed. The system should be prepared in accordance with the guidelines of BS 7593 : 2006.

The filter on the primary circuit should be checked during the first week of operation to ensure that any debris is removed.

Insulation

All pipework from and to the collector (which is not active collector) must be insulated especially when there is less than 0.8m separation between the pipes. Insulation which is to be buried must be robust enough to withstand the weight of the earth above it.

All pipework running to and from the collectors inside the property must also be insulated to a distance of at least 3m from the property. It is recommended that insulation is done prior to clipping pipes to walls to ensure complete coverage.

In some instances on pipework and exposed fittings, condensation may form which should be accounted for when choosing to site the product.
