Networked Heat Pumps

Gas usage for heating new homes will end by 2025, ahead of a net-zero commitment by 2050. Driven by the aims of the Future Homes Standard, finding reliable, cost-effective alternatives to gas is now a top priority for UK developers.

Low Carbon Heat Solutions

We provide a full-service approach that encompasses all aspects of a project. From the initial design and construction of the network to its adoption and ongoing operation, GTC is the expert partner for low-carbon heat solutions.

Serving Greener Communities

GTC’s practical, cost-effective, and zero-carbon-ready heat networks for low-density housing is a scalable, future-proof solution. We’re already delivering centralised low-carbon heat to new communities, facilitating the smooth transition from gas-fired heating to zero-carbon alternatives.

Greener Community Heat Hubs

Our community heat hub solution uses air-source heat pumps to generate low-carbon heat, delivering heat and hot water to every home through a highly insulated pipe network.

Heat pumps take heat from the air and boost the temperature using a compressor. The heat is then sent into the network so that it’s ready to keep each home warm, even on the coldest of nights, and delivers a reliable supply of hot water.

Until recently, heat networks have operated with water temperatures of around 85-90°c. New building regulations and industry guidelines now allow us to operate at lower temperatures, making plastic pipes a practical long-term solution and heat networks a very competitive option for low-density housing.

Our innovative new design uses highly insulated plastic pipes to carry water at 60°c, making it a much more cost-effective way to heat sites while keeping our customers’ homes reliably warm. Plus, there’s no need for a cylinder in the home as the network will provide instantaneous heat and hot water.

Once GTC has designed and constructed the heat network, our asset-operating sister company will adopt it. Metropolitan takes care of all ongoing operations and maintenance, along with all the service needs of the end-users, supporting the new communities connected to our networks 24/7. Read more here.
