 At Passive House Systems, we offer a wide range of Heat Recovery Ventilation units (HRV), Mechanical Extract Units (MEV) and Demand Control Ventilation units (DCV), along with all the components you will need to complete your system.

Over the past decade there has been an increased demand on builders, architects and engineers to improve the thermal efficiency of our homes. Making them draught free and well insulated. This could lead to poor air quality and can significantly increase the effects of asthma and other respiratory problems, condensation, mould growth, unpleasant smells and a build-up of toxic gases.

Our products are designed to create a proper air circulation, and thus improve indoor living conditions. An efficient and reliable ventilation system can enhance the quality of air, reducing the number of spores, pollen and humidity. Such a solution is therefore vital in rooms like bathrooms or kitchens. It also prevents mould growth on walls, floors and ceilings. All of these factors contribute to the creation of comfortable and healthy indoor climate. Thanks to clean and fresh ambient air residents can avoid headaches, allergies or problems with asthma.

Single Room Ventilation 

The Perfect Retrofit Solution

A considerable number of older housing performs poorly, when compared to the current building standards. Many homeowners are choosing to carry out multiple energy upgrades, in the process of deep retrofitting.

Through this process, the housing envelope becomes increasingly airtight. There is a greater need to extract stale air and supply fresh air throughout the house. Single Room Heat Recovery can provide an effective solution as they are designed for one room installation preventing you from having to run ducting throughout your whole house. 

Single room heat recovery units can also be installed in specific room in your house where you are experience condensation issues or poor airflow, providing you with a cost effective, easy to install ventilation solution
