Hello everyone. This would have links in it but I’m a new user!
I’m in the planning stages and am considering ventilation options.
I’m planning to have wet things in the van often - wetsuits, mountain bikes, wet boots etc.
Ventilation is certainly an important system to get right to prevent condensation and mould from these damp items - but I also don’t want to waste heat or have stale air hanging around.
I have learned that ‘passive houses’ use Mechanical Ventilation Heat Recovery (MVHR) systems. They feed in fresh air from the outside and run it in a countercurrent direction against outgoing warm internal air to allow heat exchange. e.g passivedesign .org/ mvhr
There are big units for houses and smaller units for bathrooms, the latter likely the best bet for a van.
The smaller units could have the external vents through the side of the van, the main MVHR sitting in cabinetry and ducting hoses positioned to have a vent near the cooking area and in the garage. Paired with an electric heater (ebay 2-2kw-Micro-Heater-12v-Vehicle-Marine-Boat-Van-Camper-Race-Rally-Kit-Car ) to circulate hot air around, I hope to have a system that provides and recycles hot air.
My intended van is a L2H1 Trafic.
Has anyone considered using MVHR/ implemented it into the van/ have any tips (for and against!)
Expensive waste of time? Large problem I have overlooked? Better options?
