Heat Pumps Today

22 When the owners of a 5-bedroom Essex barn conversion wanted to replace an ageing oil boiler, they turned to an air source heat pump. Essex barn conversion receives a heat pump makeover Info www.modutherm.co.uk Completed in February 2022, the installations shows how the latest heat pump technology can be e ectively utilised in larger properties. Furthermore, thanks to the use of R290 natural refrigerant within the Alira unit, the heat pump is CO 2 neutral – eliminating any damage to the ozone layer. Central to the installation was the need to maintain comfortable room temperatures all year round by utilising the existing underfloor heating and radiator circuits in the 3200 sq. ft property. The 8.5kW heat pump was easily connected to the existing 4-zone manifold, delivering a flow temperature of 45°C to the underfloor circuits and oversized radiators. Each zone is thermostatically controlled, allowing the entire home to be maintained at a comfortable temperature. For the property’s DHW requirements, the owners opted to install a new 300 litre stainless steel heat pump-ready cylinder, alongside the wall mounted Hydraulic Module. Compatible with a wide range of cylinders, the Module contains all the heating system components for simple servicing and maintenance, while its compact dimensions allowed it to be installed neatly into the existing ground floor airing cupboard. Choosing a location for the heat pump was also made simple due to its low sound pressure levels of just 45dB(A). This allowed the unit to be easily sited beneath a bedroom window without any concern. Commenting on the installation, the property owner said: “We have been really impressed with the new heat pump and how easy it was to install. The system has been working e˜ciently, even during some cold winter snaps, so we’re confident it will be far more cost-e ective to run throughout the year. It’s certainly been worth the investment, especially with the RHI available to support the installation costs. “We’ve also been impressed by the new Control mobile app and how it allows us to easily control both the heating and hot water, which again helps us to maximise energy savings.” June | July 2022 I N S T A L L A T I O N S
