Water Source Heat Pumps

Water source heat pumps can be used for heating and cooling. Pipes running to a nearby body of water (river, lake, large pond or borehole) allow it to be used as either a heat source or heat sink.

In 2017 Star Refrigeration subsidiary Star Renewable Energy was awarded funding to develop the UK’s first district heating scheme using a water source heat pump (WSHP).
The project will use a Star 2.5MW water source Neatpump on the Clyde in Glasgow. It is expected to be deployed by September 2018 and supply heat to a number of public buildings, and four tower blocks in New Gorbals.

In 2013 the Sustainable Energy Fund for Africa (SEFA) approved the $1-million (USD) project preparation grant to develop and install a deep Sea Water Air-Conditioning System in Mauritius. The system will pump cold (5oC) water through heat exchangers at a cooling station so as to cool local buildings, helping to reduce CO2 emissions by about 36,287 tonnes each year.

Glen Dimplex
Energy Efficency
System efficiency of greater than 300% when modelled with an air source heat pump in SAP 2012

The Zeroth Energy System provides low carbon heating, cooling and hot water services to residential spaces, using a low temperature network of water-water, in-apartment heat pumps.
The Zeroth Energy System consists of:
In-apartment heat pumps, connected to a refrigerant free, communal energy loop
A centralised heating or cooling plant to keep the water loop maintained at 25⁰C
The ability to facilitate a future connection to a district heat network
Within the apartment:

Each integral unit contains the heat pump technology and the hot water cylinder for each apartment
The heat pump can be specified to provide heating only or heating and cooling
The hot water cylinder is charged by the heat pump and the immersion heater
A range of hydronic emitters can be used, including fan coils and underfloor heating
