I have a Weil-McClain Ultra 230 Condensing Boiler and a Gold/Plus 80 Indirect Hot Water Heater. The unit is less than a year old. My hot water is much too hot. I just measured the faucet temp at 165F. The details are:
-I have the thermostadt on the hot water heater turned to its lowest setting. The thermostadt was already replaced once about 3 months ago when it did not seem to control the hot water. The current one seems to be working. When I turned it up from the lowest setting it sent a call for DHW to the boiler.
-The temp for space heating is set on the boiler is 180F (Setting 4).
-The temp set for DHW on the boiler is 120F (Setting 1)
-The temp on the DHW seems to fluctuate with what the boiler is doing for space heating. In the summer I was able to get the hot water out of the tap down to about 125F by lowering the DHW setting on the boiler to about 120F. Even the other day when the heat had been off for a while the hot water out of the tap was similarly at about 125F.
Any help would be appreciated.
