FairHeat Case Study – Private Developer – Heat Network Optimisation Study

The project focused on a residential development consisting of multiple blocks with a total of 791 dwellings. The development utilised a heat network for heating and hot water provision.

The heat network comprised a combined heat and power unit along with four non-condensing boilers, which supplied domestic hot water and space heating through a two-pipe system featuring underfloor heating.


FairHeat Case Study – Load Test

The new build development includes over 120 residential units along with some commercial units. A heat network provides heating and hot water via HIUs to residential units from an onsite centralised energy centre.

The heat generation is managed by three gas condensing boilers, which are supported by two 1000L thermal stores to assist during peak demand times. FairHeat was engaged to oversee Building Management System (BMS) points and conduct a LTHW system Load Test in the Energy Centre.


FairHeat Case Study – Retrofit of a Residential Development

The project involves an urban residential development comprising of 1700 homes. The architectural layout includes multiple high-rise blocks, each equipped with its own substation. These blocks are interconnected through two distinct communal networks, each powered by dedicated energy centres. Within the residences, individual heating units are installed to provide hot water, complemented by radiators for space heating.

Additionally, a comprehensive mechanical ventilation system is integrated throughout the development. FairHeat was engaged by the client to carry out dwelling inspections, a comprehensive review of retrofit calculations, and expert oversight during the commissioning phase.


FairHeat Case Study – Design and Installation

The client is a leading Housing Association with over 7,000 homes across South East England. The project was based in a Residential Care Home located within a newly constructed residential development. The facility primarily caters to elderly and vulnerable individuals. The care home is a three-storey building, with the ground floor dedicated to communal services such as a dining area, hair salon, and group activity rooms with some accommodation for residents.

The upper floors house the remainder of the residents’ accommodations. The building’s heating is provided by two gas boilers located in a ground floor plant room. Communal areas are heated directly via radiators, while individual dwellings receive heating and hot water through a single plate SAV 5-series HIU and direct radiators.


FairHeat Case Study – Energy Service Company (ESCO) – Heat Network Optimisation Study

The project is based in a residential development in south London, comprising approximately 962 dwellings across 19 sites. Each site consists of a series of low-rise blocks or townhouses. The heating and hot water for the network are supplied by a two-pipe communal heat network originating from a central plant room.

The plant room houses a gas-fired CHP and three gas-fired boilers, which serve as the primary source of heat for most of the year. Each dwelling is equipped with an indirect Heat Interface Unit (HIU) that delivers instantaneous Domestic Hot Water (DHW) and provides space heating via radiators.


Acceptance Testing, New Build Development

The client is one of the largest providers of affordable housing and care in England. The project entailed a development of 140 units located in London, with a mix of tenures (affordable rent and private).

The heat network, with heat distributed from a plant room containing boilers and CHPs, serves heat interface units (HIUs) in every dwelling providing heating (via radiators or underfloor heating) and hot water. The development consists of Guru Hubs installed in every dwelling and at block level to facilitate metering & billing and remote monitoring
