I am having two major issues with a 3 year old WM ultra boiler and indirect HWH. The system has seriously underperformed since having it installed and I'm worried something is majorly wrong with the installation. When I first had the system installed the HWH was pumping 180 degree water to our house faucets. They replaced the aquastat then eventually the hwh completely. Well the scalding hot temperatures are back and that's not all. Several people I talked to thought this was a bad aquastat again but I talked to WM rep and tested the one I have and it works properly. Along with the hot boiler temperatures, the boiler will not heat the house well when its 30 degrees. Our house will drop from 70 to 62-63 degrees overnight. I am very worried about these issues with having two, two year olds.
Today, I stood by the boiler for about an hour and tested a couple things. Firstly, I was able to activate the house zone and HWH zone while the boiler was in the standby setting. But in both cases the boiler just went from "Prepurge to Ignition to DHW/FTB to Postpurge" in a constant 1 or 2 minute cycle. The boiler didn't fire and the circulator pump for the activated zone continuously pumped. This I can remember happening the whole time we've had the boiler (again mainly at night).
I'm confident this issue along with the system heating the hot water boiler zone to 180 degrees is malfunctioning the entire system. At times it works properly but overall its a big mess. Our boiler worked for a short time today (well it heated the house), which is the confusing thing to me. It seems like the vast majority of the day these two issues arise which is certainly which is causing the unit to underperform.
Any help you could give me would be greatly appreciated. The installer is not helpful.
