HI.
I am currently looking into which MVHR unit I should get for a small house, refitted and think about the Blauberg BLAKOMFORT-ULTRA-D105-A or the Boulder DHV-04/100B.
I like with the Blauberg that it has three speed options, is quite silent ( low speed), the max 76% heat recovery and the included warranty of 5 years. But it does not offer any automatic control unit to attach.
The Boulder is a bit cheaper and just offers 3 years warranty and max 70% heat recovery. They do not give any db for the low speed function, but I have contacted them regarding this.
But therefore a separate control unit is available to adjust the speed according to the humidity.
Somehow it looks so to me that the Blauberg is more popular.
Anyone here which has them and would like to share their experience ? And of course any other input is more than welcome.
Is there maybe another MVHR unit which I oversee, but is rather reasonably priced and better than those two?
Thank you in advance for your thoughts and help.
Cheers
Manfred
