DOMESTIC VENTILATION SOLUTIONS
Heat recovery retrofi t solution is perfect fi t for
T
he Housing Association opted for two products from the Heat Recovery Retrofi t Solution, the Lo-Carbon Tempra and the Lo-Carbon Heat
Save, to be installed on the social housing project. The driving force behind this project was to introduce energy effi cient ventilation into these properties which would improve indoor air quality (IAQ) for the residents, as well as providing heat recovery benefi ts and energy savings. In addition to providing energy effi cient ventilation,
protecting the fabric of the properties and Almond HA’s investment in its housing stock was a crucial factor on this project and the Heat Recovery Retrofi t Solution helps with this. The work started in early March 2023 and was completed within four weeks by Saltire FM, the contractors on the project. Architectural services were provided by MAST Architects, Glasgow. Vent-Axia, a specialist in low carbon ventilation, launched its Heat Recovery Retrofi t Solution to help deliver decarbonisation to social housing providers. The range has been specifi cally developed to provide increased ventilation, while minimising unnecessary heat loss through heat recovery technology. The Tempra single room heat recovery units were chosen for the wet rooms (kitchen and bathroom) and the Heat Save single room heat recovery units for the habitable living room areas in the homes. The units replace existing “extract-only” ventilation in the kitchen and bathroom areas. The single room heat recovery units off er greater payback to both resident and housing provider through energy savings, as well as protecting the properties from condensation and mould. “The fans were easy to install and good quality. We also had great service and after sales,” said Andrew Moxen, electrical supervisor at Saltire FM. “At Almond HA we are delighted with the
performance and effi ciency of the Tempra and Heat Save units installed in our Laurel Grove project. By improving indoor air quality, it helps protect the health of our residents and the fabric

Almond Housing Association is the second largest landlord in West Lothian with a stock of over 2,500 properties. When the Housing Association was looking for energy effi cient upgrades of existing ventilation in 32 of its properties in Laurel Grove, Livingston, West Lothian, it turned to Vent-Axia’s Heat Recovery Retrofi t Solution
ventilation solution to support their journey towards Net Zero and healthier homes. The Lo-Carbon Heat Save is designed to off er either single room heat recovery or as part of a whole house heat recovery ventilation solution for existing homes. This technology is a fi rst, alternate fl ow heat recovery off ers a balanced, modular, customisable ventilation system that can be easily retrofi tted, providing both supply and extract while recovering heat from the air. Achieving up to 84% heat recovery, the Heat Save uses the warmth from outgoing air to heat incoming air to avoid heat loss and to reduce energy bills for households. Using two or more fans within a property, the unit uses a reversible fan that alternates between supply and extract every 70 seconds.
of the properties. We would have no objections using Vent-Axia products on future planned and reactive programmes,” said Stewart Fisher, asset & development offi cer at Almond Housing Association. The UK is committed to meet Net Zero targets by
2050, setting a tough challenge for social housing providers to improve their energy effi ciency and so lower the carbon emissions in their properties, without detrimentally aff ecting the IAQ in their homes. Increasing airtightness in homes to improve energy effi ciency, without providing adequate ventilation can create areas where moisture condenses, leading to mould growth which blights many homes across the UK. Social housing providers recognise the challenges and are looking for solutions to protect their housing stock and residents. This is where Vent-Axia can provide the right
The Lo-Carbon Tempra single room heat recovery unit is a discreet, low energy, continuously running alternative to traditional extractor fans that off ers aff ordable heat recovery of up to 78% and improves air quality on a room-by-room basis. The through- the-wall mounted unit simultaneously extracts stale air and introduces fresh air – warming the incoming airfl ow with heat recovered from the exhaust air. Allowing simple installation through a 100mm diameter hole in a wall, the design of the unit enables standard bathroom, kitchen, toilet or utility room fans to be easily changed for a Tempra without the need to make the install hole larger. The unit’s performance, using a low carbon DC motor, brings signifi cant energy savings and will help reduce a home’s carbon footprint.
The Heat Recovery Retrofi t Solution has been designed for easy, lower cost retrofi t of heat recovery to save maximum energy and emissions in the social housing sector. The Heat Recovery Retrofi t Solution range consists of three diff erent mechanical ventilation with heat recovery units, which can be used together to help improve IAQ and maximise energy savings by introducing heat recovery to the property. The range comprises: the Lo-Carbon Heat Save and the Lo-Carbon Tempra, which are both wall- mounted through-the-wall units and the Lo-Carbon Calido, which utilises a simplifi ed ducting system that can run within the home to supply fresh fi ltered air to a diff erent room.
