Baxi HP60 R290 High Temperature Monobloc Air Source Heat Pump – 4kW / 6kW / 8kW / 11kW / 13kW (Single & Three Phase)
Baxi HP60 R290 High Temperature Monobloc Air Source Heat Pump – 4kW / 6kW / 8kW / 11kW / 13kW (Single & Three Phase)
The Baxi HP60 is a high-temperature monobloc air source heat pump charged with R290 (propane) refrigerant — a natural gas with a global warming potential of just 3. Delivering flow temperatures up to 75 °C, the HP60 is one of the few ASHPs capable of replacing a gas boiler on existing radiators without major upgrades. Available in seven outputs from 4 kW to 13 kW (single-phase, with three-phase options on the 11 and 13 kW models), every variant is MCS-certified and Boiler Upgrade Scheme eligible.
With a SCOP of up to 5.34, an A+++ ErP rating across the range at 35 °C flow, and a sound power level from just 48 dB(A), the HP60 provides space heating, hot water and optional cooling from a single self-contained outdoor unit — no indoor refrigerant module, no on-site brazing.
Key features
R290 natural refrigerant
Charged with 0.7–1.25 kg of R290 propane — global warming potential of just 3, compliant with current and forthcoming F-Gas legislation.
High-temperature output
Delivers up to 75 °C flow at A−10 °C ambient — ideal for retrofits where existing radiators stay in place without oversizing.
A+++ ErP rated
A+++ at W35 across the full range, and A+++ at W55 on the 4, 6 and 8 kW models. Among the most efficient ASHPs in the UK.
Whisper-quiet operation
Sound power from 48 dB(A) — comparable to a domestic fridge. Suitable for tight urban gardens under MCS 020 noise rules.
Reversible heating & cooling
Provides space heating, DHW and active cooling in summer, with hot water available across the full −25 °C to +46 °C ambient range.
Variable-speed drives
Inverter-driven compressor and variable-speed pump modulate to match demand, reducing cycling and electricity use.
MCS-certified, BUS-eligible
Every variant carries an MCS certificate and qualifies for the Boiler Upgrade Scheme (up to £7,500) and ECO4.
Up to 7-year warranty
Standard 2-year warranty, extendable to 7 years when installed by a Baxi Works–registered BHPI-trained engineer.

Sizing depends on a heat-loss survey by your MCS-certified installer or use handy Spruce calculator.
