Baxi HP40 4kW Monobloc Air Source Heat Pump
The Baxi HP40 4kW Monobloc Air Source Heat Pump has been designed to provide well-insulated homes with low cost heating and hot water. They work by drawing out natural heat from the outside air, and continue to do so in temperatures as low as -25°C.
Built by Baxi, a company with over 150 years of heating experience, the HP40 range gives you reliable heating, simple plumbing for installation, and silent modes of operation for reducing noise levels.
Features & Benefits: Baxi HP40 4kW
Precision Output: Instead of inefficient on/off cycles that waste energy by constantly stopping and starting, the Baxi HP40 adjusts its power to match actual heating needs as the temperature changes.
Monobloc Design: With all of its internal components sealed inside one outdoor unit removes the need for complicated refrigerant installation. It also gets rid of technical on-site F-Gas handling.
Works in Low Temperatures: Continuing to work in outdoor temperatures all the way down to -25°C, these units are truly dependable when the cold weather hits.
ADEY Protection: The HP40 comes with an ADEY magnetic filter that traps sludge and debris, shielding internal pumps from early wear.
Baxi Cylinder Integration
To get the best results when heating water, we recommend pairing the 4kW HP40 with Baxi’s purpose-built range of hot water cylinders that boost heating efficiency. Depending on how much hot water you generally use, Baxi recommends a hot water tank between 100 and 250 litres for this model.
