Baxi HP40 7kW Monobloc Air Source Heat Pump 7kW

Baxi HP40 7kW Monobloc Air Source Heat Pump

The Baxi HP40 7kW Monobloc Air Source Heat Pump provides homes with a sustainable source of heating and hot water. Heat pumps work by drawing out geothermal heat from the atmospheric air to be used for heating your home, outperforming conventional fossil fuel boilers on both costs and their environmental impact.

This 7kW model gives you more power than the smaller 4kW or 5kW units in the Baxi HP40 range, they’re ideal medium-sized homes or for domestic properties looking to accommodate higher heating demands.

At National Heater Shops, we recommend that all heat pumps are correctly sized for the homes they are to be installed in. An MCS-certified installer must check heat output using BS EN 12831 calculations. This requires them to conduct a room-by-room heat loss calculation to boost SCOP (Seasonal Coefficient of Performance) and meet compliance regulation. This provides the homeowner with the correct sized heat pump while lowering annual electricity bills.

Features & Benefits: Baxi HP40 7kW

• 7kW Capacity: Ideal for medium homes, typically around 3-bedrooms.

• Monobloc Design: All components are housed inside one unit and installation is straightforward.

• A+++ Energy Rating: At a 35°C flow it can reach a SCOP of up to 5.03. This means that for every 1kW of electricity used, 5kW of heat is produced.

• Works Down to -25°C: Perfectly suitable for providing heat even during cold UK winters.

• Quiet Running: From a 1 metre distance it operates at 48 dB(A), ideal for small gardens that are close to neighbours.

Hot Water Connection

We advise customers to pair their purchase with a Baxi ASHP cylinder for domestic hot water (DHW) purposes. These cylinders feature large internal coils that rapidly heat water to be used for your everyday hot water needs such as showering. Obviously, no cylinder is required if the heat pump is there only to provide your home with central heating.

For the 7kW model, we recommend a 210L to 300L cylinder. However, this really comes down to how many people live at the property and how much demand there is for hot water on a daily basis.
