Hewer, a leader in sustainable heating solutions, has launched Heat Saviour™, a groundbreaking technology that simplifies heat pump installations and maintenance, saving time, money and hassle.

Heat Saviour™ is a first-of-its-kind pre-assembled unit which conveniently sits underneath a standard hot water cylinder. 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.

Stuart Hesk, Director at Hewer, said: “Installing and retrofitting heat pumps can be complex, costly and disruptive. Heat Saviour™ is a much smarter and cheaper way to install and use a heat pump, making property management easier and improving home occupier satisfaction. We saw the amounts of unnecessary waste, cost and downtime that installing and retrofitting heat pumps was causing. As a customer-first business, we set about inventing a solution to tackle these issues.”

With glycol only in the heat pump circuit, Heat SaviourTM 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. The unit also has a built-in backup heating element, which can either be switched on manually or controlled remotely, avoiding downtime during maintenance or pump failure – crucial for vulnerable people - and reduces how often engineers need to enter the property.

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.
