Weil Mclain Ultra/DHW Issues again
My DHW is pushing out scalding hot water - much hotter than normal. Our faucets all have to be almost completely turned to cold to take a shower.
I checked my system out and the demand for heat is almost always taken up by the DHW. As a result, my heating system cant keep up with the cold temperatures outside and its mid 60's in my house.
The first winter I had the ultra/DHW system (which was winter 10/11), I had the same exact issue. The company replaced the thermostat first in the DHW, which didn't help and a few days later replaced the DHW completely. I haven't had many issues until now.
I have a feeling these issues are due to a bad installation. I read the manual when we first started having issues 3 years ago and found several things the installer left out which they ultimately fixed. Still they wouldn't install the outside temperature sensor and wouldn't install an air intake to the outside after asking. I was told my house wasn't sealed enough from the air to matter. Lastly, my system has never worked that well at heating the house when temperatures are low.
I really don't know what to do, because Im worried the same problems are going to happen again and again. When I contact the installer today to look at this issue should I expect this will be covered under warranty? I am considering contacting Weil Mclain directly to have a look at the installation just to make sure the boiler itself hasn't been damaged and to make sure the installation is correct. There are still a couple things done different from the manual? Any suggestions? I have kids and I don't want them to get burnt by the hot water or get sick because its so cold in here at night.
