The aim of this project was to provide a system that delivers efficient, high-quality heating, cooling and ventilation to an existing traditional build bungalow.

The system needed to be controllable, efficient, simple, effective and affordable.  The installation is required to be scalable, in terms of application and value whilst addressing issues of ventilation, indoor air quality and possible overheating within the property.

• Householders in this property type are more likely to be elderly and less mobile
• Many householders have downsized to a smaller property, and with a lifetime of possessions means that space can be at a premium.  Radiators and panel heaters may become obstructed and this impedes heating and the flow of air within the property.
• Costly and inefficient heating systems are less likely to be used.  This results in under heated, poorly ventilated properties that may be subject to damp and mould.
• Householders often create conditions that are likely to cause issues., ie, don’t open windows, cook without lids, don’t close the door to the bathroom, hang wet washing by heaters, etc.

To meet these challenges, they turned to the Unico System.

Mid Devon District Council selected the Unico SDHV system based on its innovative design which delivers conditioned and enhanced indoor air quality.  The system integrates a humidistat controlled MEV and maintains an exchange of fresh air to the property.  The advantage of being able to locate the distribution system in the roof space.  The longer term operational benefits include the price point, the integration of known technologies (ASHP) and the potential for future installations to be delivered by the DLO.  The enhanced environmental controls maintain healthy households, reducing pressure on the local NHS and GP surgeries.  We also expect the system to be fundamental in helping with the reduction of disrepair claims as a result of damp and mould.
