Now tht the ceiling plasterboard is going up, we are gluing up our duct work for the heat recovery and comfort cooling sytems. here is a collection of “sub - assemblies” that have been glued up. This just leaves us the remaining joints to glue or tape with duct tape once the assemblies are slid into place.

The system has taken a lot more time to think through the routing than expected. Working in 3 dimensions with such large pipework is a challenge, even in a new house. It is certainly worth getting the basic pipe runs in place before the plumbers and electricians get too far into the job because firstly you may have to have boxing in in places that might be helpful for them, and it stakes your claim on bits of space!
