Micro heat networks
Funding & Returns
Working with Kensa’s Non-Domestic RHI eligible micro heat network scheme (also known as district heating), a phased installation programme can be managed in line with the project schedule.
With individual heat pumps at each dwelling the properties enjoy independent heating & hot water and reduced bills, whilst the need for a plantroom is removed, freeing up more real estate to be developed.
A win-win for developers and prospective buyers.
Heat network schemes & the RHI
Two or more properties on a shared ground array qualify as a heat network scheme.
Better still, heat network systems reduce installation costs.
As a result the developer can receive an RII of 6-13% on the installation.
The heat network approach is suitable for clusters of properties, including multiple occupancy dwellings.
With Kensa’s Shoebox ground source heat pumprange, flats and apartments are now also able to benefit from this efficient technology which generates guaranteed heat all year round, as well as a guaranteed income every quarter for 20 years through the Non Domestic RHI.

A ground source heat pump’s (GSHP’s) efficiency results in exceptionally low running costs.
In typical housing developments each unit of electricity consumed by the heat pump delivers around four units of heat.
Assuming electricity costs around 16p per kilowatt hour, the kilowatt hour price is effectively quartered which means the running costs (at 4p kWh) will be lower than those delivered by a mains gas boiler; maintenance cost will be negligible and carbon emissions will also be lower.
For these reasons, the specification of GSHP’s allow developments to be marketed under an ultra-green, energy efficiency banner with demonstrably low running costs, an attractive opportunity given the current focus on energy costs.
Developments featuring Kensa ground source heat pumps benefit from reduced CO2 emissions and improved carbon compliance compared to traditional fuels.
Equally, in gas connected areas ground source heat pumps provide a carbon compliance solution without the need for supplementary carbon saving measures, such as solar PV.
Building Regulations Part L are becoming increasingly stringent in the use of energy and CO2emissions. By replacing a conventional fossil fuel based heating system with a ground source heat pump, higher levels of building efficiency and CO2saving can be achieved.
CO2 emissions from new buildings are measured in SAP. While electricity is considered a relatively carbon intensive fuel, the efficiency factor of a ground source heat pump reduces the emissions from space and water heating by up to two-thirds.

This is provided the initial HCA bid did not specify that a renewable heat technology would be installed and the housing association maintains separation between accounts receiving HCA funds and accounts making payments for the renewable technology.
