Low carbon, low cost heating and hot water 

The challenge

The most common form of heating across the Partners residential estates is gas fired boilers. Partners are looking for an alternative method to provide heating and hot water as a result of rising costs, awareness of carbon emissions and the legislative changes banning gas boilers in new properties from 2025. It’s also important to the Partners to reduce the cost of energy to tenants, particularly to address fuel poverty.

A number of the Partners residential estates are social housing or student housing that could benefit from centralised systems. Heat pumps are not commonly used but could be explored; however, the main blocker in the past has been return on investment.

The solutions we are seeking

The Partners are looking for a low/zero carbon, low-cost heating and hot water solution, that provides a return on investment.

In some cases, the solution could provide heating and hot water to a large array of properties in the same area, i.e. a heat network.

Some buildings have very little space for large technologies and so smaller solutions would also be suitable.

Partners are aware of models such as Energiesprong and would be interested in similar approaches, alongside individual technological solutions.

Selection criteria

The technology is affordable for both Partners and customers, with an ensured ROI.

Improvement of SAP ratings will be a key metric, especially when a minimum standard is introduced in the social housing sector.

The strategy for implementing low carbon technology needs to be aligned with UK infrastructure - the grid needs to be fit for purpose.

Both mature and early stage technologies will be considered, however preference will be given to tried and tested technologies.

Varying payback periods would be considered dependent on technology and cost.

Maximum power generation is important for any kit as this may feed into a financial model that would make the installation of the kit viable.
