Installers Are Raving About These 5 Heat Pump Game-Changers – Are You Missing Out?

As heat pumps continue to dominate low-carbon heating installs across the UK, one thing is clear: not all systems are created equal, and high-temperature systems need specialist support.

That’s where Altecnic’s newly extended range comes in. Designed specifically for high-temp, high-performance heat pump setups, these products are more than just accessories, they’re essential tools for safeguarding system efficiency, protecting components, and delivering long-term results installers can rely on.

Here’s why it matters and how these products can help…

iStop® High Temperature Anti-Freeze Valve w/ Swivel Connection

A frozen system is an expensive system. Designed to operate at up to 90°C, this valve is built specifically for modern heat pump systems using next-generation refrigerants like R290. When water temperature drops to around 3°C, the valve automatically drains the system to prevent freezing damage. The swivel connection also makes installation fast and flexible, minimising stress on site.

Insulated ASHP Hoses

High-temp systems mean higher surface temperatures, and that means heat loss if your connections are not properly insulated. These pre-insulated flexible hoses offer superior thermal protection and simplify installation by reducing the need for external lagging. This combines efficiency and convenience in one, with various lengths available depending on your install!

Magnetic Filter Ball Valve

Installers love a product that multitasks. This unit acts as a combined magnetic filter and isolating ball valve, capturing debris while making maintenance straightforward. Especially valuable for high-temperature circuits where sludge and magnetite can rapidly compromise performance.

5516 Caleffi HED® – High Efficiency Deaerator

Air is one of the most underestimated threats to any heating system, and in high-temperature heat pump installations, its impact can be particularly severe. Designed to discharge up to 99% of air in a single pass, the 5516 protects your system from noisy operation, internal corrosion, cavitation, and flow blockages, issues that are magnified at higher temperatures and pressures.

Caleffi XF Heat Pump Filter

Made for the demands of heat pump systems, the XF Filter traps debris before it reaches vulnerable components. Unlike conventional filters that force 100% of flow through the filter body (risking pressure drop and pump strain), the XF’s bypass diverts up to 50% of the flow around the filter element. This reduces pressure drop and lowers circulator workload, a key benefit when flow rates are harder to maintain at high system temperatures.
What’s more, the XF can be inspected and cleaned without shutting down the system, maintaining flow continuity and avoiding lockouts. That means fewer disruptions, lower energy use, and happier customers.

Together, these five products form an installer-ready toolkit for protecting high-temperature heat pump systems, boosting performance, and delivering the reliability today’s heating demands.

Why It All Matters

High-temperature heat pump systems are increasingly used in retrofit applications and hybrid installations, where demand and stress on components are greater. Standard parts often can’t cope with the thermal intensity, leading to inefficiencies, wear, and dreaded callback costs.
Altecnic’s extended range helps future-proof your installs, whether you’re working with new builds, older properties, or advanced refrigerants.

Installers: it’s time to raise your heat pump game. Are your systems high-temp ready?
