Baxi has introduced a new range of residential air source heat pumps (ASHPs) as part of a complete packaged solution that includes cylinders, controls, training, enhanced warranty options, nationwide commissioning and aftersales support1. The announcement was reported by the Chartered Institute of Plumbing and Heating Engineering (CIPHE) on 17 August 2023, which lists Baxi as an Industrial Associate1.
The new Baxi HP40 Monobloc Air Source Heat Pump range is available in outputs from 4kW to 13kW at UK winter conditions, which the manufacturer describes as providing a low-carbon solution for heating and hot water in every size of property1. The units are designed for use with the Baxi ASHP Cylinder and are supplied with a magnetic filter as standard to protect the heating system, while DC inverter technology is used to maximise energy-efficient operation1. The company states the unit has an extremely low sound level1. Warranty options run to up to five years, subject to terms and conditions1.
The HP40 range is joined by a freshly updated Baxi Assure heat pump range, aimed at housebuilders, developers, social housing providers and their appointed contractors for installation into new build and social housing properties1. Baxi states it combines over 150 years of experience of heating UK homes with over 30 years of European heat pump innovation from its parent company, BDR Thermea Group1. Following the establishment of its Heat Pumps Competence Centre in 2018, BDR Thermea has tripled the number of engineers dedicated to heat pump innovation across the continent, according to the report1.
Harriet Evans, Renewables Director at Baxi, said:
"We understand that many heating engineers will need to become familiar with ASHPs for the country to hit that 600,000-heat pump installation target, so we want to make their move to renewables as seamless as possible. Whether installers are new to heat pumps or already have a recognised heat pump qualification, we offer everything they need to become comfortable with Baxi's Air Source Heat Pumps, from initial training and on-site commissioning support on the first install to expert customer service and aftersales advice."
She added that heat pumps are an important technology for decarbonising heat in homes and that the company is committed to giving installers support from discussing the technology with customers to delivering performance, efficiency and energy savings1.
Why it matters for households
For a household weighing up a heat pump, the practical question is rarely the box on the wall alone. A monobloc unit still needs a cylinder sized for the home's hot water demand, controls that suit the existing radiators and pipework, and someone competent to commission it. Baxi's pitch is that these elements arrive together, with the magnetic filter fitted as standard to catch debris that would otherwise circulate through the system1.
Outputs spanning 4kW to 13kW at UK winter conditions cover a wide spread of property sizes and insulation levels, from a small flat to a larger detached house, though the correct figure for any individual home depends on its heat loss, which is not something a range alone determines1. The warranty of up to five years is conditional, and the terms have not been set out in the announcement1.
For energy independence, an air source heat pump shifts a home's heating away from gas and towards electricity, so the running cost and carbon position depend on how that electricity is generated and priced. The announcement does not include efficiency figures, running costs or grant eligibility, and none of these have been reported here1. Households comparing brands may also look at the Grant and Vaillant ranges, among others listed under heat pump manufacturers supplying UK homes.
What happens next
No launch date, price or availability date for the HP40 Monobloc range is given in the announcement1. Baxi directs readers to its own product page for further information on the range1.
