UK Homes Get Free Hot Water

A new UK company, Heata, has developed a innovative solution to reduce domestic gas bills by converting waste heat from cloud computing into free hot water for households. The system, known as a 'data furnace', involves installing rented servers in homes and using the heat generated to warm water for showers and hot taps.

The process is straightforward: Heata installs a compute module in the home, which is attached to a hot water cylinder, heating the water and reducing the requirement for gas heating. The heat generated by the servers is passed to the water supply, providing free hot water for the household. Heata also pays for any additional electricity used by the mini server, ensuring that homeowners do not incur any extra costs.

The potential impact of this technology is significant. According to Heata, the waste heat from a single data center could provide hot water for around 30,000 homes. This could lead to a substantial reduction in domestic gas bills, with Heata's system aiming to provide around 80% of heat for the heating system.

To be eligible for the system, homes need to have fast broadband to provide fast data routing to the compute module. This allows the compute module to function efficiently and generate the heat needed to warm the water.

Heata is not the only company offering this type of solution. Another company, Thermify, is also providing a similar service using a HeatHub with Raspberry Pi Compute Modules. This growing industry offers homeowners the chance to cut their energy bills significantly while providing businesses with low-cost server space.

## Why it matters The use of waste heat from cloud computing to provide free hot water for households has the potential to make a significant impact on reducing energy bills and carbon emissions. As the demand for cloud computing continues to grow, the amount of waste heat generated by data centers will also increase. By harnessing this waste heat, companies like Heata and Thermify are providing a innovative solution to reduce energy consumption and provide a cost-effective alternative to traditional heating systems.

## What happens next As the industry continues to grow, we can expect to see more companies offering similar solutions. With the potential to reduce domestic gas bills by up to 80%, this technology is likely to become increasingly popular among homeowners. As the technology continues to develop, we can expect to see even more efficient and cost-effective solutions for harnessing waste heat from cloud computing.
