What is FTX?
In Sweden, FTX means a supply and exhaust ventilation system with heat recovery. Fresh air comes in, used air goes out, and heat is recovered from the extract air before it leaves the house.
Fresh air in
Clean supply air is delivered to bedrooms, living rooms and other occupied spaces.
Used air out
Extract air is normally taken from bathrooms, laundry rooms and kitchens.
Heat recovery
Heat from the outgoing air is transferred to the incoming cold air.
Better comfort
More even ventilation, better indoor air quality and less draft.
Who is HusFlow for?
This service fits homeowners who want to understand the project before buying materials or bringing in contractors.

Common problems in older Swedish homes
Poor indoor air and stale feeling
Common in homes with outdated extract-only or natural ventilation.
High energy use
Especially when heating is based on direct electricity.
No clear technical plan
Quotes are hard to compare if you do not know what the system should look like.
Unnecessary material purchases
Many homeowners buy wrong dimensions or wrong components at the start.
From idea to practical plan
You get a practical plan that fits your house, not a generic drawing that leaves you with more questions.
