The range

Meeting improved energy efficiency requirements for new homes combines efficient heating, insulation, better air tightness and a controlled ventilation strategy. An integrated, new generation, high efficiency wholehouse heat recovery system is by far the most efficient ventilation solution for new ‘tight’ buildings.

A 90% efficient wholehouse heat recovery unit for properties with a volume of between 600 and 900m3.

The Xpelair Xcell 300 and 400 are ideal for larger properties in order to meet the half an air change per hour requirement. As the extract points are in the ‘wet rooms’ – bathrooms, en-suites, cloakroom and kitchen, the air change rates in these individual rooms will be substantially higher.

At the heart of the unit is a 90% efficient heat recovery cell which transfers the heat from the outgoing exhaust airflow to the incoming fresh air whilst keeping the two flows separated. As the temperature of the outgoing air drops, it reaches dew point and gives up condensate. The warming process to the incoming air reduces its RH ensuring a fresh, condensation free indoor environment. The unit features LongLife DC motors designed for continuous operation and exceptionally low running costs. The unit design allows the outlet spigots to be set vertically or horizontally to suit site conditions. The unit is fitted with two cell pre-filters which are user accessible from the outside and without having to isolate the unit.

Xcell 270 - DC wholehouse heat recovery unit

SAP Appenix Q recognised, a new breed of high efficiency MVHR units designed to save energy and function reliably with extremely low running costs

Key features

• Legislation: Building Regulations BRE Digest 398 (1994), SAP Appenix Q recognised
• Spigot diameter: 150mm

The range

New building regulations are striving to improve energy efficiency in the home and reduce CO2 emmissions.

Part L places greater emphasis on airtightness in new homes to reduce the energy loss through uncontrolled air leakage, so the need for an intelligent controlled ventilation strategy is becoming more critical.

Wholehouse ventilation with heat recovery, is often referred to as MVHR.
It provides a constant background flow of fresh tempered air to the living spaces of a ‘tight home’ whilst extracting condensation, smells, tobacco smoke and volatile organic compounds via kitchens, bathrooms and toilets. The resultant lower humidity deprives the house dustmite the conditions in which to breed, thus contributing to a healthier environment.

The Xpelair Xcell 270 is one of a new breed of high efficiency MVHR units designed to save energy and function reliably with extremely low running costs. It maintains a cosy indoor environment during the colder months and provides an ‘aired’ feeling even when the building has been closed up for long periods.

The Xpelair cell is housed in an insulated cabinet and integral filters are designed to make access to the cell unnecessary – keeping maintenance to a minimum.

Xpelair LongLife DC fan units not only ensure a low running cost but they are also much more efficient than ac motors – keeping energy usage down.

A choice of ten preset performance programmes enables flexible control over air quality and when combined with a manual switch or automatic sensor, the ventilation rate can be increased temporarily to reduce humidity – perfect for bath and shower rooms.

Fitted with a fan failsafe interlink, if one fan is stopped, the other will automatically switch off - particularly important in homes with open fires or unvented boilers.

Housed in a stylish cabinet, the Xcell 270 can be unobtrusively mounted in an airing cupboard, on a kitchen wall or within a roof space.
