Hi, just joined this forum but have been looking at posts for a while. I run a domestic/commercial heating and plumbing company in Ireland and started using Viessmann vitodens 100-w boilers in Domestic side a year ago. Before these boilers arrived on the market here i installed the old reliable two zone s plan central heating system with either Glowworm or Bosch. When i've installed the Viessmann and upgraded the pipework i used there four pipe system as i think weather comp is going to be the next big thing and i want the boilers to be in full condensing mode most of the time, 50 degrees flow and 30 degrees return.
Has anyone been installing the four pipe system and what do you think about the cylinder getting priority over space heating. I'm getting a few customers that can't understand why the two can't be on at same time. I only realized this was the case after my first four pipe install and found it strange. Any thoughts anyone. Cheers
