With Kensa’s innovative micro ground source heat network and the Shoebox heat pump, developers can benefit from 20 years of quarterly payments through the Non Domestic Renewable Heat Incentive (RHI).

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.

How it works:

Kensa’s micro ground source heat network sees the installation of a small, ultra-quiet, Shoebox ground source heat pump within each property, linked in turn to a series of shared boreholes via low temperature distribution pipework around the building.

This has the unique benefit of providing each resident with their own heating appliance, which can be linked to the developers preference of radiators or underfloor heating, in exactly the same way as an individual gas boiler, but of course without the gas safety concerns or annual servicing requirements.

And because the water distributed around the building is on the “cold side” of the heat pump, it is not subject to heat loss or any requirement to invest further in plant to overcome heat losses.

Better still, each resident’s heat pump is connected to their personal electricity supply, meaning each settles their own bill directly with their preferred energy supplier and is perfectly able to switch suppliers as and when they see fit.  This is in contrast to any heat supply contract which would otherwise be the case with a central plant heating system, where all residents are tied into the incumbent “heat supplier”.

Each home is furnished with its own Shoebox heat pump which, virtually silent in operation, fits in a single footprint below its own hot water cylinder, providing each resident with plentiful hot water and saving valuable space inside the property.

Ground source heat pumps also exhibit significant CO2 savings over alternatives.  Although a unique solution systems can easily be modelled in SAP, and Target Emission Rates improvements of 40% or more are typical, enabling developers to easily meet carbon compliance objectives without the need for additional costly measures to satisfy Building Regulations Part L requirements.

Crucially, this system architecture is classified as district heating and as such new build installations qualify for subsidy support via the Non-Domestic strand of the Government’s Renewable Heat Incentive (RHI) scheme.  This subsidy support means there is opportunity for the building management company to generate a long term income stream from the production of renewable heat.  Alternatively funders can provide the additional capital to cover the initial cost of the ground array, in return for allocation of the RHI funds, allowing the possibility for the ground array infrastructure to be owned and maintained by a separate entity, as is already commonplace with electricity and gas infrastructure for new build sites.

The Shoebox and supporting shared ground array system architecture ensures a competitively priced heating and hot water system, allowing the house-builder to market the development under a ‘green banner’, whilst offering low running costs to the homeowners and minimal carbon emissions.

Kensa Heat Pumps has been designing and manufacturing ground source heat pumps for self-builders in the UK since 1999.

The British manufacturer supplies more ground source heat pumps in the UK than any other, making Kensa the preferred choice for the British home (Source: BSRIA 2017).
