Inside an average modern day residential home, with proper central heating, you will encounter a certain degree of air pollution; and the perfect way to combat this, would be to install a heat recovery ventilation system.
By having a wholehouse heat recovery system installed inside your residential house, this will replace the exisiting air inside the property at certain intervals throughout the course of the day, replacing the stale air with clean filtered air.
As well as being compact in design, these heat recovery systems are also compliant with building regulations, as well as being SAP Appendix Q Eligible too.
