Domus Ventilation’s HRXE Mechanical Ventilation with Heat Recovery (MVHR) and CMX-MULTI Mechanical Extract Ventilation (MEV) systems, along with Domus ducting, are being installed in to the new Kilburn High Road residential development in North West London.
Kilburn High Road is a development of one and two bedroom apartments from Kilburn Developments Ltd.
Located on one of London’s busy main roads, indoor air quality has been a key consideration, which drove JP Electrical Ltd. to specify and install Domus Ventilation’s range of mechanical ventilation systems.
Director Nick Jordan stated: “They are really good units and easier to install than others I’ve used. I’ve never had a problem with them.” Jim also has praise for the service provided by Domus Ventilation: “Domus did all the design drawings for this project free of charge which massively helped and they have provided on-site support too.”
Domus Ventilation HRXE MVHR systems with NOX-FILT in-line carbon filter have been installed in the ground level apartments within a cupboard, with CMX-MULTI MEVs in the remaining apartments, fitted in the ceiling voids.
The HRXE MVHR combine supply and extract ventilation in one system. They efficiently recover up to 90% of the heat typically lost in waste, stale air and use it to temper the fresh air drawn into the apartment via an advanced heat exchanger. The filtered, pre-warmed air is distributed to areas of the home such as living rooms and bedrooms, effectively meeting part of the heating load in energy efficient dwellings. The systems themselves use very little energy due to their efficient design, including a very low Specific Fan Power (SFP) down to just 0.57W/l/s.
To filter out harmful airborne contaminants prevalent in our cities, the HRXE has been fitted with Domus Ventilations NOX-FILT in-line carbon filter. Designed to work on the supply leg of the ducting system to the HRXE, NOX-FILT removes up to 99.5% of nitrogen dioxide (NO²) pollution from entering a home.
Domus Ventilation’s CMX-MULTI is an extremely compact and highly energy-efficient centralised MEV. It extracts indoor pollution and draws moisture-laden air out of wet zones, such as kitchens and bathrooms, depositing it outside for greatly improved indoor air quality and environmental comfort. At just 125mm in depth, the CMX-MULTI is the smallest and lightest MEV on the market, enabling it to readily fit into ceiling voids, as is the case at Kilburn High Road. As with the HRXE, the CMX-MULTI is energy-efficient, with an extremely low Specific Fan Power down to 0.1457W/l/s - the lowest in the market today and well below Building Regulation Part L requirements of 0.5 W/l/s.
To ensure maximum systems performance, Domus Supertube 204x60mm rigid ducting and EasiPipe 125mm round rigid ducting have been used with the mechanical ventilation systems. These duct systems offer improved system performance through the exacting tolerances and engineered fit of the system, whereby pressure drops are minimised and air leakage virtually eliminated.
In line with Building Regulations, Domus Fire Collars have been used wherever a hole has been made in a compartment wall for the ducting to pass through in order to restore the walls’ fire rating. Domus Thermal ducting insulation has also been used where the ducting passes through unheated areas and voids, to prevent condensation forming.
