Energy saving legislation means our focus is on building air tight, highly insulated homes. Heat loss has been reduced but are we in danger of creating unhealthy, polluted living environments?

25 years ago in Sweden, the construction industry had to face up to the material and health costs of Sick Building Syndrome - the result of a move to well insulated houses. The Swedes’ response was to develop whole house ventilation with heat recovery, literally a breath of fresh air for low energy homes.

Recovering heat from the humid areas of the house to a heat pump maximises energy efficiency whilst ensuring poor, damp exhaust air is regularly replaced with fresh air, creating a warm and healthy indoor climate free of moisture and mould. This is now the de facto solution installed in 90% of new houses in Sweden.

With years of refinement, improved efficiencies and proven effectiveness in one of Europe’s most demanding climates, the heat recovery units and heat pumps from leading Swedish manufacturer NIBE offers UK self-builders and housing professionals a ready-made solution.
