Example: Multiple Buildings

Where there are multiple buildings on one site all requiring heating and hot water, a micro-district ground source heat pump system architecture can be utilised to provide a low cost and ultra-efficient heating solution.

A micro-district ground source heat pump system features individual heat pumps in each dwelling, all fed from the same central ground array. This ground array can be made up of either coiled pipe known as slinkiesboreholes or pond mats, and it is sized to deal with the peak heat demand of all the dwellings combined.

Benefits of a micro district system

As each dwelling features its own individual ground source heat pump, the occupier has complete control of their own heating and hot water system. And because the heat pump is connected to the house electrical distribution board, the occupier receives their own bill, therefore eliminating the need for any cross-billing.

Because heat is produced by the individual heat pump inside each dwelling, there are no external heat losses which makes this system not only versatile but also energy efficient.

Do you have a water source?

Water is an excellent conductor of heat and therefore water source ground source heat pump systems are extremely energy efficient.

If your development has access to a stream, river, pond or lake, then you should consider harnessing this freely available energy source.

Do you have lots of land area?

If the property is rural and surrounded by lots of exposed land area, then slinkies would be a viable option for a ground source installation.

Slinkies are the name given to coiled pipe buried in trenches at a depth of 1-2m where the ground temperature remains constant all year round.

Do you have limited land area?

If the complex is in an industrial area for example and has limited exposed land, boreholes would be the best option.

Boreholes can usually be drilled into any type of ground and are a perfect space-saving solution, as the depth of the hole(s) is varied to suit the heat requirement.
