How can a data center heat a home like the Bridges'?

The data center generates heat as a byproduct of its computer operations, which is then captured and used to heat the home's hot water system.

What is the SHIELD project in the UK?

SHIELD is an initiative by UK Power Networks focused on developing and implementing low-carbon technologies for vulnerable and low-income households.

Who developed the HeatHub data center used by the Bridges?

Garden Shed Powers Home Heating for £40/Month

In an innovative energy solution, Terrence and Lesley Bridges from Braintree, Essex, are now heating their home for a mere £40 per month. Their gas boiler has been replaced by a 'HeatHub' data center, housing over 500 computer banks within a garden shed. This system captures the heat generated by the computers, channeling it directly into the couple's hot water system.

Previously spending up to £375 monthly on heating and electricity, the Bridges' experience a dramatic cost reduction and consistent warmth throughout their bungalow. This pioneering project is part of UK Power Networks' SHIELD initiative, designed to help low-income households achieve net-zero energy consumption. The HeatHub, developed by Thermify, has been installed in collaboration with their landlords, Eastlight Community Homes.

This eco-friendly scheme, which also includes solar panels, demonstrates a practical approach to reducing fuel poverty and improving home energy efficiency. With plans to expand the initiative to 50 more homes and a broader ambition to scale up significantly, this data center heating solution offers a glimpse into a future of affordable, clean energy for many.
