COMPLETE HEAT PUMP PACKS, DESIGNED FOR INSTALLERS
Developed to simplify and future-proof heat pump installations, Heat Saviour Plus separates the system into two distinct circuits for improved performance and flexibility. The primary circuit forms a contained, small glycol volume loop between the heat pump and the Heat Saviour Plus unit. The secondary circuit operates as a standard water-based heating circuit within the property.
This intelligent separation allows existing radiator pipework to remain in place, significantly reducing system disruption, installation time, and overall project costs.
TYPICAL HEAT PUMP SYSTEM VS HEAT SAVIOUR PLUS
By introducing a locally isolated glycol-filled circuit to the primary pipework, Heat Saviour allows any heat pump to be mounted externally.

IT SOLVES REAL WORK PROBLEMS THAT ENGINEERS DEAL WITH EVERYDAY
We’ve used heat saviour on multiple installs and it’s never let us down. No call backs, no complaints. Just solid performance. We’ve built our reputation doing things right the first time, and Heat Saviour helps us do exactly that.
TG Plumbing
A KEY PART OF OUR HEAT PUMP INSTALLATION TOOLKIT
The installation process is incredibly straightforward and its space saving design allows us to fit systems neatly and efficiently, even where internal space is limited. We have never had a single call back or system fault related to the unit. That level of reliability is rare and invaluable.

ASKED QUESTIONS
Quick, straightforward answers to help you understand our solutions, how they work, and what to expect from installation to long-term performance.
Heat Saviour is a pre-assembled 600 mm-square retrofit module that sits beneath your hot-water cylinder and hydraulically links any air- or ground-source heat-pump to your existing heating loop via a plate heat-exchanger. Its dual-circuit design keeps the refrigerant/glycol side entirely separate from your radiators, protecting the pump from sludge and allowing installers to use standard, readily available components.
A Worcester 25KW 4000 or a 28CDI Compact, usually suits these properties, however we would always recommend a free survey to allow us to recommend the most suitable product for your needs.
Usually not—the dual-loop layout lets the new heat pump run independently of your existing central-heating circuit, so most homes keep their current emitters and pipes intact. Only badly undersized or single-pipe systems will need additional work, which your installer will flag during the survey.
Heat Saviour is designed to slide into a standard 600 mm × 600 mm airing-cupboard footprint beneath a conventional hot-water cylinder. That makes it a good fit for UK homes where cupboard real-estate is tight.
Yes—the plate-exchanger interface works with all MCS-approved air- and ground-source heat-pump models, so you’re not locked into proprietary parts.
Keeping the glycol loop separate slashes sludge ingress and cuts glycol use by around 80 %, leading to fewer filter blockages and call-backs. Installers can service the pump without draining the whole heating system, reducing downtime for occupants.
Yes—a factory-fitted electric immersion element can be switched manually or via remote controls, keeping the house warm during pump maintenance or extreme cold snaps.
By shaving thousands off the upfront plumbing bill, Heat Saviour often leaves the £7,500 BUS grant covering most—if not all—of the remaining equipment cost, making a heat-pump swap financially easier.
Hewer FM offers a lifetime parts guarantee on the Heat Saviour module itself, plus the standard manufacturer warranty on any paired heat-pump.
Yes—more than 1,000 social-housing properties have already been fitted with the unit, with zero post-installation call-backs reported to date.
