Larger plantroom modules are supplied in modules, which are linked together. They do not come with integral water pumps, these are generally sized by the M and E consultant. However Kensa would be happy to advise on these if required.

In communal applications buffer tanks are sometimes required, due to the large variation of loads and turndown issues. In this case Kensa would generally recommend a two connection buffer tank installed in the heat pump return, after the low loss header. This will allow the required flow rate to be maintained through the heat pump and keep a sufficient volume of water 'in circuit' to prevent short cycling. This enables the heat pump to cope with low load conditions, while not introducing any inefficiency associated with indirect buffer tanks.

Each individual apartment or property will generally require a heat meter installed on the individual dwelling so that the energy used by the occupants can be measured. This will enable accurate billing of the energy used for that dwelling.
