Individual heat pump with radiators.
When operated with radiators to avoid short circulating problems, one bypass radiator should be left ‘open’, i.e. any TRV is removed. This radiator can be positioned in areas such as halls or bathrooms.
It is important that the heat pump has been specified as operating on radiators, as a higher outlet temperature will be required and a ‘smart start’ is necessary to limit any electrical disturbances caused by the compressor starting.
Kensa would always recommend fitting an expansion vessel on the heating distribution circuit.
