Heat Recovery

What is Heat Recovery?

Current building regulations require that new properties are built with high levels of insulation and air-tightness, making them substantially more energy-efficient. A side effect of these construction methods can result in poor indoor air quality as condensation and stale air generated from cooking, cleaning and bathing remain trapped inside.

Mechanical ventilation with heat recovery (MVHR), provides a solution to these problems, significantly improving ventilation and air quality, whilst recovering the heat that would otherwise be lost outside.

Typically MVHR systems are implemented with a central fan and heat exchange unit (or more than one in larger properties) with internal pipework running through ceiling voids and loft areas to most rooms and vented to the outdoors though wall or roof vents.

Extract pipework takes warm moisture-laden, stale air from ‘wet’ areas, such as kitchens and bathrooms. The heat from this stale air is recovered in the heat exchanger, and used to warm fresh air from outdoors delivered via the separate supply pipework into the living areas of the home.

Why use Heat Recovery?

The insulation levels in new build properties can be so good that over 50% of heat loss and hence energy costs can be due to ventilation losses. MVHR provides a solution to recover that energy whilst also ensuring that you benefit from excellent indoor air quality.

  • Significant energy savings with very low running costs
  • Substantially improved air quality throughout the property
  • Heat from secondary heat sources (e.g. stoves) distributed through the house
  • Low noise levels – essential as MVHR systems are constantly running
  • Full design and installation package available
  • 5 year warranty
  • Options for summer bypass and integral frost protection
  • Low maintenance and easy access filters (no tools required)

Trusted Energy are very experienced MVHR installers with over 30 installations in the last 5 years. We are able to advise on system design and installation with customers benefiting from our experience to avoid background noise issues which are not uncommon in poor designs.
