Heat Recovery Ventilation

Rega Ventilation have been manufacturing HRV (Heat Recovery Ventilation) systems for 30 years. Specialising in systems tailored to the UK climate, our extensive experience and knowledge with the systems has allowed us to produce a range of the most efficient and low power consumption units available.

Mechanical Ventilation with Heat Recovery provides an energy efficient way of maintaining a fresh and pleasant atmosphere in the home whilst saving money on heating bills.

It works by extracting the warm, moist air from rooms such as bathrooms and kitchens where condensation is a major factor.  The unwanted air is passed through a heat exchanger then ducted to outside.  Fresh air from outside is drawn in and passing through the heat exchanger; recovering up to 90% of the heat taken from the extracted air, it is then ducted throughout the house encouraging positive air circulation.

Why do I need Heat Recovery Ventilation?

​

The effects of poor ventilation

• Condensation forming on windows and puddles on window sills.
• Mould growth.
• Damage to the fabric of the building.
• Build-up of harmful gases, such as carbon dioxide.
• Stale, musty environment.
• Increased numbers of dust mites due to moist conditions.

Benefits of heat recovery ventilation?

• Maintain a fresh atmosphere in a well-insulated home.
• Removes moisture from the stale air within the house, reducing the risk of condensation problems.
• Improved air quality will alleviate the symptoms of asthma sufferers.
• Filtered fresh air will reduce the effects of many respiratory allergies.
• Prevents damp and mould growth.
• Allows the home to be tightly sealed, reducing noise entry in urban areas.
• Controlled air changes mean no over ventilation, keeping heat losses to a minimum.
• Heat recovery efficiency of up to 90% resulting in reduced heating requirements.
• Reduced decorating costs.
