3.2.4 Hot water production with VUI boiler
The hot water production with additional stratified cylinder
functions in the same way as on the VUW boiler (¬Sec-
tion 3.2.3).
In addition, you can activate the heating of the stratified
cylinder by switching on Comfort mode. This uses special
charging technology to ensure that you have a similar hot
water convenience as you would get with a much bigger
conventional domestic hot water cylinder. You immediately
get hot water at the required temperature without having
to wait for the water to heat up and you have a larger hot
water volume at your disposal.
