Weil-Mclain ECO 70 cycle rate.
Hey everyone. Searched around the forum to find the answer but i just couldnt. I may be thinking into this more than i should but Id thought Id ask.
Recently had a WM ECO-70 installed that heats 2 (2 thermostats) zones of radiant infloor (staple up). Previously had outdoor wood boiler which I got rid of and replaced with the propane boiler.
To me, the cycle times are a lot longer than i thought. The thermostat will kick on one of the zones, take about 15-20 min to reach target supply temp. Usually like on a day like today 20-25F out, it would fire for about an hour and a half give or take and then shut off. Thermostat wouldnt make a call for heat for another 2 to 3 hours due to the house holding the heat the the residual heat from the heating tubes/floor. Sometimes overshoot by 1 degree. (Set at 71 in the main living room zone).
Here are my settings, Supply max set at 170 degrees, supply min set at 120, boost interval set at 45 minutes.
To me the house is warm and comfortable. Wife is warm and comfy too so thats a plus. Havent really gone through a lot of propane gas at this point but its a little early to tell.
Any help/input would be greatly appreciated. If there is anything else i missed, ask away. Thanks!
