Has anyone here put in these units. We have twinned 200,000 BTUH
units to install ina a 100 yr old 6300 ft2 house, with integrated DHW
, Viessmann is assisting.
Does anyone have any experience with these units. They are the
highest efficiency boilers on the market Wondering about their
reliability and ease of service. Have sold/installed other Viessmann
products with great results.
Thanks in advance.
