ECO & SUSTAINABILITY
New, groundbreaking heat
pump technology saves
homeowners £2,000 per
installation
First-of-its-kind technology installed in over 1000 social houses across the South West
Hewer, a leader in sustainable
heating solutions, has launched
Heat Saviour™, a groundbreaking
technology that simpli昀椀es
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 retro昀椀tting
heat pumps can be complex,
costly and disruptive. They
are often designed with nonuniversal 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 to
install and use a heat pump,
making property management
easier and improving residential
satisfaction. We saw the amounts
of unnecessary waste, cost and
downtime that installing and
retro昀椀tting heat pumps was
causing. As a customer-昀椀rst
business, we set about inventing
a solution to tackle these issues.”
Heat Saviour™ is a 昀椀rst-of-itskind pre-assembled unit which
conveniently sits underneath
a standard hot water cylinder.
Unlike traditional heat pump
systems, which tie households
into speci昀椀c manufacturers’
components due to their singular
loop design, Heat Saviour ™
enables the use of off-theshelf 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 (expensive
antifreeze), 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. 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.
Installed in 1,000 social houses
Over 1,000 social housing
properties across the South
West are already bene昀椀ting
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 昀椀lters, which can reduce
performance and affect reliability.
“Our mission was to design
a cost effective, durable and
sustainable solution which makes
the government heat pump
grant go further. A design which
simpli昀椀es 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.
Sam Batt, Asset Investment
Manager at Two Rivers Housing
in Newent, Gloucestershire,
said: “Heat Saviour has been a
valuable part of our latest Social
Housing Decarbonisation Fund
project at Two Rivers Housing,
installed successfully as part of
the wider renewable technologies
we have employed. Both these
and the air source heating
systems have proven reliable and
have been an important step in
our journey towards net zero.
We have found them a reliable
solution, smoothly installed by
engineers who have been a
pleasure to work with.”
Stuart added: “If the
government succeeds in its
goal of installing heat pumps in
600,000 UK homes a year, and
each property is 昀椀tted 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.”
Founded in 1965, the
company employs over 160
people, offering a wide range of
heating, mechanical, electrical
and renewable services for
both domestic and commercial
customers.
