Vent-Axia, the leader in low carbon ventilation, has launched the Vent-Axia Lo-Carbon Heat Save, which is designed to offer either single room or whole house heat recovery ventilation solution for existing homes. The decentralized heat recovery ventilation unit is ideal for retrofitting, providing extract and supply ventilation to improve indoor air quality (IAQ) and supply fresh air to rooms as part of a modular system. 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.
The UK has enshrined in law the need to achieve carbon neutrality by 2050 but there is a long way to go. To reach this target, improving the energy efficiency of existing homes is essential since 40% of carbon emissions are currently generated by buildings. This will mean improving insulation, making homes more airtight, and adding heat recovery ventilation to ensure good IAQ. However, a whole house mechanical ventilation with heat recovery (MVHR) system is difficult to retrofit given the huge rework required of the electrical and ductwork systems. Vent-Axia is therefore supporting the Government in reaching their target by offering the Vent-Axia Lo-Carbon Heat Save as an energy efficient solution.
“As homes become more airtight to meet carbon targets, heat recovery ventilation is going to become increasingly important in achieving this objective,” says said Tom Wodcke, product manager at Vent-Axia. “As traditional MVHR units are not viable for many retrofit properties, a decentralized approach is needed which is where the Vent-Axia Lo-Carbon Heat Save comes to the fore. Thanks to its high efficiency ceramic thermal accumulator, the Vent-Axia Lo-Carbon Heat Save recovers up to 84% of the heat of extracted air that would otherwise be lost to the outside and uses this to warm incoming air.”
The Vent-Axia Lo-Carbon Heat Save is designed as a decentralized heat recovery ventilation system for homes, using two or more fans in habitable rooms. The unit uses a reversible fan that alternates between supply and extract fan modes every 70 seconds to extract dirty air from the room and replace it with outside air that has been passed through a filter to ensure that clean air enters the room. Ideal for using in pairs, as one unit is extracting, the other is supplying fresh air to provide a single room or whole house balanced ventilation system with heat recovery.It’s also easy to expand as needed, adding more units for a whole house solution which can all be controlled from one controller which can operate up to eight units in synchronization.
For homeowners the Vent-Axia Lo-Carbon Heat Save offers ‘Fresh air without the breeze’ – no need to open windows and let out all the heat in winter. As a retrofittable heat recovery ventilation unit with an air cleaning filter, households will see drastic energy consumption savings and improved indoor air quality. Heat Save is very energy efficient, using only up to 3.1W. The units are also easy to maintain and clean, with filters simple to change as the units are not in the loft. Controlled by a SENWZP Sentinel wired-zone controller the Heat Save is fully modular and controllable with customised ventilation profiles available so every room in the house can have perfect ventilation. It also comes with a 5-year warranty for peace of mind.
Meanwhile, for electricians the Vent-Axia Lo-Carbon Heat Save increases ventilation as part of a holistic condensation and mould prevention strategy while providing multiple avenues for up-sell including heat recovery; a zone controller; sensors; and filters. It’s also easy to install since there is no need for ducting, a wall sleeve is included and the unit simply goes through an external wall. The Heat Save is adapted for wall thickness from 185 – 310mm so it is suitable for a wide range of building types. This powerful fan also fulfils S3 classification according to EN 13141-8.
And for electrical wholesalers the Vent-Axia Lo-Carbon Heat Save is a great item to stock thanks to its many attractive benefits for electricians and their own customers. As we see more energy efficient homes become the norm, retrofittable heat recovery ventilation will become essential to ensure a healthy home. Heat Save reduces a home’s carbon footprint and saves money on energy bills whilst being easy to install in retrofit homes and fully customisable via a control panel. All this adds up to happy customers and increased revenues from larger job values.
