ᐅ Difference Between Air-to-Water Heat Pumps Viessmann and Dimplex

Hello everyone,
We are currently deciding whether provider A or provider B should build our house.
Provider A offers a Dimplex LI 9 TU with indoor installation,
Provider B a Viessmann vitocal 200s as a split system.
Could you share your experiences or opinions on these?
Thank you.

Best regards

I would choose the Viessmann because it looks nicer. 😀
