Heat Recovery Ventilation Systems

Paul Heat Recovery Scotland provides energy efficient ventilation solutions for sustainable homes in Scotland. Our company started as the Scottish and Northern Irish distributor for Paul Heat Recovery Ventilation Systems (MVHR), but we have recently diversified into a range of high performance products, to serve the different requirements of residential and commercial developments, new built as well as renovation projects.

Highly efficient heat recovery ventilation is the ideal partner for buildings which are relatively air tight. Air tightness goes hand in hand with good standards of insulation in the drive to optimise the energy efficiency of buildings.

Please note that we are currently moving office. Unfortunately during this time (until the 8th June) we have limited design and project management capacities. Thank you for your understanding and patience. 

Passivhaus, NZEB and Low Energy Development Specialists

passivhaus-low-energy-buildingsWe specialize in Passivhaus, Nearly Zero Energy Buildings (NZEB) and low energy developments. Please contact us if you need advice regarding alternative heating methods for Passivhaus projects.

Paul has become well known for its highly efficient and Passivhaus certified HRV systems, widely used in Passive Houses/Passivhaus and low energy buildings. Developed and made in Germany, its systems stand out with excellent technology, optimal heat recovery rates, low energy consumption and last but not least, very silent operation. We provide the world leading products in efficiency and energy use according to the Passive House certification.

With our consultancy and design service, we are a reliable partner for installers and companies in the construction industry.

What is Passivhaus?

Passivhaus is the optimisation of a building’s thermal performance, based on building physics.

With the help of the Excel based calculation program PHPP, designers are supported to find the optimal design and specification for a new building.

The German Passivhaus Institute has formulated an energy performance standard for Passivhaus buildings as a target value. The following graphic puts the passive approach and Passivhaus into the picture of sustainable buildings and renewable technology:
