Which manufacturer of air-to-water heat pump is recommended according to the offer?

Hello everyone,

we have offers for 3 different systems of air-water heat pumps with ventilation systems and for selection.

Which systems would you recommend here in your opinion?

I am not looking for a detailed evaluation, but rather whether any of the providers should not be recommended at all or if one of the systems should definitely be chosen.

It concerns:

1. Viessmann Vitocal 200-S with Vitovent 300
2. Stiebel Eltron LWZ 304 Flex
3. Buderus Logatherm WLW 196i IR and Vallox ventilation system

does anything particularly stand out here? What about with regard to indoor and outdoor installation?

From gut feeling I would choose the following order:

1. Buderus
2. Viessmann
3. Stiebel Eltron

What do you think?

Thank you very much

The service technicians from Stiebel Eltron are good. Friendly, polite, competent, work cleanly. We have a field trial system from Stiebel and Tecalor. I cannot tell you anything about your systems.
