The cost of clean heat: why system efficiency matters

The cost of electricity relative to gas is back in the spotlight, with renewed calls for government to make low-carbon heating more affordable.

A new report from Energy UK argues that rebalancing energy prices could accelerate heat pump adoption, estimating a narrower gap could support at least 250,000 additional domestic installations by 2030.

The debate highlights a wider challenge for the UK’s transition to clean heat. Heat pumps can deliver significantly more heat energy than the electricity they consume, but their running costs also depend on energy tariffs, the performance of the system and how well it is designed.

For housebuilders and developers, this makes efficiency an important consideration from the earliest stages of a project.

Getting more from every unit of energy

With electricity prices remaining relatively high compared with gas, designing heating systems to operate efficiently is particularly important.

Lower flow temperatures can help heat pumps achieve higher efficiencies, but this requires a system designed to deliver the necessary heat output at those temperatures. Correctly sized emitters, compatible underfloor heating and well-configured controls all have a role to play.

These decisions are connected. Heat emitters need to be specified around the building’s heat loss and the intended operating temperatures, while controls help ensure the system responds appropriately to demand.

Getting these fundamentals right can support efficient operation, occupant comfort and lower running costs. It can also reduce the risk of costly adjustments after installation.

Making low-carbon heating work in practice

Energy prices and government policy will influence the pace of heat pump adoption, but the quality of system design remains a practical consideration for every project.

For developers working towards the Future Homes Standard and the wider transition to low-carbon homes, considering the complete heating system rather than treating the heat source as a standalone decision, is vital.

At Vogel Noot Solutions, our specialist brands support projects across heat pump distribution, underfloor heating and commercial heat emitters. Bringing these areas of expertise into the specification process helps project teams consider how the different components work together, from design through to installation.

The national conversation may be focused on the price of electricity, but the wider objective is evident. The focus needs to be delivering low-carbon heating that performs efficiently in homes and buildings.
