As per the title. Is it possible to DIY one of these systems? We're moving house next year and want it to be a healthy home because our present house is condensation and mould city. Do these units require building regs? Any warnings or watchouts when buying or fitting? The diagrams look fairly simple, extract from kitchen and bathroom and vents to bedrooms and living rooms.
Would you also have traditional extraction from kitchen and bathrooms? Or could you do away with this?
