Create a healthy and productive environment in the home, silently and efficiently

Mechanical Ventilation and Heat Recovery is the future of indoor air quality and energy efficiency. It is designed to maintain a constant flow of fresh air within a building while  simultaneously capturing and recovering heat from the outgoing stale air. This process ensures a continuous supply of clean tempered air, optimising comfort and energy efficiency

What is Mechanical Ventilation and Heat Recovery?

The MVHR system extracts stale air from the home and replenishes it with fresh air, without any impact to the temperature of the room. Our smart ventilation systems can ventilate by zone when it is needed, making them quieter and more energy efficient. We provide both Mechanical Extraction Ventilation(MEV) and Mechanical Ventilation Heat Recovery (MVHR).

Enhanced air quality

Filters out pollutants, allergens and contaminants promoting a healthier living and working environment

Meet requirements

Necessary in polluted or noisy areas where you can't open windows

Energy efficient

be recovering heat from exhaust air, MVHR systems significantly reduce heating costs

Constant fresh air

consistent influx of fresh air without compromising on energy efficiency

Reduce carbon footprint

Pellentesque porta urna ac dolor eleifend placerat. Praesent pretium sit amet lacus vel bibendum.

Suitable for small spaces

Ideal for air tight modern buildings or passive housing

Works with the Radiant Cooling System

to reduce dew point by reducing the rooms humidity levels allowing lower cooling flow temperatures

How does MVHR work?

Sensors continuously measure air quality and humidity, when it falls below a preset parameter the central MVHR unit will bring fresh air through the supply ducting into the room. Stale air is removed from kitchens, bathrooms or areas with high activity and fresh air is brought into living spaces and bedrooms. Depending on the system that is selected, zones can be set up so only occupied rooms are switched on further improving efficiency.

Why is it important to measure air quality?

We spend typically 60 – 80% indoors, in modern buildings there are high levels of insulation which can lead to a buildup of pollutants such as Volatile organic compounds (VOCs), moulds, dust mites and other allergens. This can trigger respiratory problems, allergies and other health issues. By well ventilation the room and adding filters to MVHR we can ensure fresh, clean air in our homes with no impact on the temperature of the room.

Good air quality is also linked to better cognitive function and air quality. Poor quality can lead to discomfort, fatigue and a decrease in overall well being. People are more likely to be productive and comfortable in environments with clean air

How loud is MVHR? Will it disturb my sleep?

Sound is a key factor for MVHR, it’s essential your system is well designed, specified and installed. At Surface Renewables we sell Duco system, the quietest MVHR system in Europe that uses a simple ducting system, Duco flex which further improves efficiency of the system. UK building regulations offer guidelines regarding maximum sound levels, recommending a level of 30 dB for noise-sensitive rooms such as living rooms and bedrooms, and 45 dB for other rooms such as kitchens and bathrooms. Our units fall well below that threshold, and our inhouse design team will ensure you have the right set up so that your sleep will not be disturbed.
