As renewable heating system grow in popularity, and as Government adopt policies that see renewable been specified in preference to the standard fossil fuelled alternatives that we come to relay on over the year, we’re having to adopt to new ways of achieving what we all want from our heating systems – Effective space heating to keep us warm and comfortable in the colder months of the year and reliable supplies of domestic hot water.

Traditionally for most of us, heating systems have been gas or oil boilers – for most of us, combi boilers – driving our heating systems – but legislation is driving these down the pecking order with traditional boilers effectively not installed in new build domestic homes from 2025 and an expectation that legislation will be brought in soon to ban them from being used in replacement heating systems in existing homes – probably by 2035, but possibly sooner. In their places we are seeing the need to install renewable heating systems – in the main, the installation of heat pumps to provide heating and hot water. Heat pumps are gaining popularity in the UK for efficient and sustainable home heating. However, a proper room-by-room heat loss calculation is essential for an effective heat pump system.

A room-by-room heat loss calculation is vital for an efficient heat pump system. This ensures the correct sizing of the heat pump and heating distribution, leading to optimal performance and cost-efficiency.

As part of air source heat pump survey TM Refrigeration Ltd also provide the full measurements of existing radiators and the room available for future changes. We understand the importance of sizing radiators correctly with air source heat pump and our professionally trained office staff specialise in heat loss calculations. This allows them to accurate calculate the correct radiators needed for the designed flow temperature of the ASHP that has been selected for the job.

TM Refrigeration Ltd offers this service starting at £250 + VAT for properties up to 300m², a worthwhile investment considering the significant costs of heat pump installation. Contact TM Refrigeration Ltd for a fully MCS compliant heat loss calculation.
