Building Regulations

All Nuaire units are compliant under Part F & L of the 2010 Building Regulations.

Physical Dimensions

The MRXBOX95B-LP1 is spefically designed to fit within a ceiling void over 200mm deep. This allows for valuable storage/cupboard space to be left vacant perfect for appartments. Please check the installation manual for dimensions.

Automatic frost protection

The MRXBOX95B-LP1 unit has a automatic frost protection. If the outdoor temperature drops below -5 Deg.C the air intake is disabled and the unit serves as an 'extract only' system until the weather improves.

Summer Bypass

An automatic summer bypass is fitted as standard to the MRXBOX95B-LP1. If the outdoor air temperature exceeds 20 Deg.c the bypass opens and the heat recovery function is automatically disabled. Under these conditions the unit provides fresh filtered air throughout the property to help reach a comfortable temperature.


The MRXBOX95B-LP1 is to be installed within the ceiling void space. An access pannel will need to be accomadated to access to the filters and control panel. The unit has a unique feature in that the spigots are 204x60mm box. This saves money on ducting and increases fan performance. Solarcrest provide a nationwide supply, installation and commissioning service with BPEC certified installers. We also provide commissioning only, required under 2010 regs, if you prefer to install the system yourself. In which case we can provide installation guidance by telephone and email. Don't forget, draughty trickle vents and airbricks will not be necessary with an MVHR.


The MRXBOX95B-LP1 requires an annual inspection and clean, normally with a vacuum cleaner. More frequent inspection post-building work is prudent as the filters are likely to pick up more dust than normal. The G3 grade filters in the MRXBOX95B-LP1 can be easily accessed via the underside panel. The unit will require an access panel to be accomadated within the ceiling. Other than the filter inspection the MVHR is a fit and forget item. All Nuaire units come with a 5 year warranty for added peace of mind


Solarcrest will assess your floor plans and ventilation requirements in order to recommend the most appropriate MVHR system. We'll then provide accurate budget costs for the supply, installation and/or commissioning of the system to current building regs. Subject to an initial deposit we release our proposed ducting design and air flow specification for consideration by your building inspector. Subject to approval we can normally have the complete system on site within a week.
