The Skvallertorget housing association in central Kalmar wanted to improve energy efficiency at the property and initially considered converting to an FTX system. Its apartments were previously supplied with extract air ventilation only.
The association decided to use EcoHeaters for the property as they could be installed without disturbing tenants and yet the solution they offer is energy-efficient.
The EcoHeater was lifted down through the hole in the roof that was made for the previous extract air fan, and a storage room in the attic could be used as a fan area.
