Mixergy 210L R290 iHP Integrated Heat Pump Cylinder

The Mixergy 210 Litre R290 iHP Integrated Heat Pump Cylinder is a smart unvented hot water cylinder with an integrated R290 air‑to‑water heat pump, designed to deliver highly efficient, low‑carbon hot water for medium to large all‑electric homes.

Product Description

Part of the Mixergy iHP X R290 range, the 210L model combines a Duplex stainless steel cylinder with a top‑mounted R290 heat pump head. Using patented top‑down stratified heating, it delivers usable hot water in under 30 minutes while using around three times less electricity than a conventional direct electric cylinder. The unit connects to the Mixergy app for machine‑learning schedules, time‑of‑use tariff optimisation and live hot water level monitoring.

Key Features

• Integrated R290 heat pump: Compact indoor air‑to‑water heat pump built into the cylinder head – no separate outdoor unit required.
• High efficiency: CoP ~3.4 and ErP A+ rating, significantly reducing running costs versus direct‑only cylinders.
• Fast hot water: Top‑down heating provides usable hot water in under 30 minutes, up to 10× faster than conventional integrated HP cylinders.
• Smart control: Mixergy app with machine learning, smart scheduling, Boost, usage insights and time‑of‑use tariff support.
• 210L capacity: Suited to typical family homes with higher hot water demand.
• Engineered to last: 25‑year cylinder warranty and 5‑year heat pump head warranty (typical Mixergy terms).
• Modular design: Cylinder and head supplied as two pieces for easier handling and installation in tight plant spaces.

Included Components

• Unvented kit: pressure reducing valve, check valve, pressure & temperature relief valve, expansion relief valve, tundish and expansion vessel (with mounting bracket and 3/4″ × 22 mm adaptors).
• Back‑up immersion heater (≥2 kW, 1¾″ BSP, factory‑fitted).
• Integrated R290 heat pump head unit.
• Powerline‑to‑Ethernet adapter and Ethernet cable.
• Control gauge and onboard electronics.
• User Guide and iHP X installation/servicing instructions.

Applications & Notes

• Ideal for medium‑to‑large all‑electric homes and apartments where an external heat pump is impractical or undesired.
• Suitable for retrofit and new‑build installations, fitting much like a standard unvented cylinder but requiring an external wall for the 150 mm air ducts.
• Optimised for smart tariffs and eco‑operation via the Mixergy app’s machine‑learning schedules and energy insights.
• Must be installed and commissioned by a G3‑qualified installer in accordance with Mixergy’s iHP X installation manual and local building regulations.
