Heat Saviour™ cuts heat pump installation time, disruption and labour costs by 20%
Press Release 3rd June 2025, UK: Hewer, a regional leader in sustainable heating solutions, has launched Heat Saviour™, a groundbreaking technology that simplifies heat pump installations and maintenance, saving time, money and hassle.
As part of its Net Zero plan, the government aims to install 600,000 heat pumps annually by 2028, with gas boilers banned in new homes from 2027. Yet heat pump sales fell short last year, barely hitting 100,000, according to the Heat Pump Association. In response, the government has pledged to double the Boiler Upgrade Scheme (BUS) to £295m and launched a public awareness campaign to spotlight the £7,500 heat pump grant.
Stuart Hesk, Director at Hewer, said: “Installing and retrofitting heat pumps can be complex, costly and disruptive. They are often designed with non-universal parts, requiring entire heating systems to be ripped out – systems that could have years of use left in them.
“Heat Saviour™ is a much smarter and cheaper way for engineers to install and maintain a heat pump, making property management easier and improving residential satisfaction. We saw the huge amounts of unnecessary waste, cost and downtime that installing and retrofitting heat pumps was causing, and so, as a customer-first business, we set about inventing a solution to tackle these issues.”
Heat Saviour™ is a first-of-its-kind pre-assembled unit which conveniently sits underneath a standard hot water cylinder, transferring the heat fed from the heat pump through a plate exchanger, which indirectly powers the central heating system. Unlike traditional heat pump systems, which tie households into specific manufacturers’ components due to their singular loop design, Heat Saviour ™ enables the use of off-the-shelf components for quicker installation. Operating on a dual-circuit loop, the heat pump runs independently of the existing central heating, eliminating the need for system overhauls. This minimises disruption and downtime, cuts labour costs by up to 20%, and delivers homeowners savings of up to £2,000 per installation.
With glycol only in the heat pump circuit, it cuts glycol use by 80%, which is better for the environment, and allows radiator maintenance without the costly expense of having to drain and replace the glycol solution. The unit also has a built-in backup heating element, which can either be switched on manually or controlled remotely using a Vericon Systems connected solution. This avoids downtime during maintenance or pump failure – crucial for vulnerable people – and reduces how often engineers need to enter the property.
Installed in 1000 social homes
Over 1,000 social housing properties across the South West are already benefiting from Heat Saviour™ including those managed by social housing providers; Two Rivers Housing, Bromford, Green Square Accord, Rooftop Housing Group, Community Housing and Cottsway Housing Association.
Stuart continues: “There’s been no post-installation callbacks on the social housing installations since we implemented Heat Saviour ™. One of the reasons for this is due to the central heating circuit being separate from the heat pump. This helps to prevent sludge from older systems – often still present even after cleaning – from reaching the heat pump filters, which can reduce performance and affect reliability.
“Our mission was to design a cost effective, durable and sustainable solution with lower upfront costs and simple servicing, which makes the government heat pump grant go further. A design which simplifies installations from new builds to even older properties, which aren’t conducive to heat pump systems; meeting the needs of all homeowners, landlords and tenants, including social housing providers.
“A compact unit which fits into a standard 600mm by 600mm cupboard, Heat Saviour™ works with all major heat pump brands and comes with a lifetime guarantee on its parts. It ensures that the heat pump runs more efficiently, cutting energy waste and enhancing the system’s overall effectiveness. The shelf-life of the heat pump also improves as there’s no relying on manufacturers’ own parts, which can go out of production, while less glycol in the system dramatically reduces the system’s impact on the environment.”
Daniel McNally, Director of heat pump installation firm, EcoHeat Plumbing, Heating and Renewables, said: “Heat Saviour has now become a standard part of our toolkit for every suitable heat pump installation. It delivers on every front, lower installation costs, simpler maintenance and enhanced homeowner satisfaction. For us, it’s more than a product, it enables better service and advances system design.”
Stuart added: “If the government succeeds in its goal of installing heat pumps in 600,000 UK homes a year, and each property is fitted with a Heat Saviour™, that’s an annual saving of £1.2 billion for the economy. Our unit empowers more communities to adopt greener heating methods, and most importantly, offers peace of mind – delivering reliability without the fear of premature failure.”
Hewer was founded in 1965 by David Hewer, starting as a modest heating and plumbing service in Gloucester. The company now employs over 160 people at its offices in Quedgeley, offering a wide range of heating, mechanical, electrical and renewable services for both domestic and commercial customers.
