Hello, I was wondering if anyone has had any experience with a Komfovent Domekt R 400 V MVHR unit please? I am about to replace my Frankische unit which we are having issues with the Komfovent Domekt R 400 V. It will be located in the loft, and I'm told the Komfovent Domekt R 400 V is designed for cold installations (hence popular in Scandinavia). The current Frankische doesn't like the cold despite being well insulated, and should really only be installed in the warm floors in the house. We can only place the unit in the loft, hence having a specialist take a look, and they are recommending the Komfovent Domekt R 400 V. Thank you in advance for your advice :)
