After 12 years or so of fitting Viessmann boilers, I finally got the opportunity to fit a Vitodens 200-w system boiler. Another first for me was the use a plate heat exchanger to separate the sealed boiler side from the open vent radiator circuit. New 200 litre unvented cylinder replaced the open vent hot water cylinder. The boiler is controlled by weather compensation making it as efficient as possible. The 7” touchscreen can located at the bottom or the top (like in the picture) of the boiler.
