Hey everyone, just had a couple questions for those of you using an OWB. First of a little background on me. My wife and I just built a new house. We are heating the house and DHW with a couple plate exchangers fed by the OWB. Our unit is a brand new Crown Royal Stoves 7400e. Love the boiler. It appears to be super efficient. We just started burning about 5 days ago and I am very pleased. Inside the house we have radiant floor heat for the basement, garage, and we ran the piping on the underside of the sub floor for the main floor and it works awesome. I'm using a 12 zone Cross Manifold for the majority of the house, and a taco 4 zone for the garage and 1 zone in the house.
Do you guys all run your circulating pump on the back of the boiler at full speed? Only reason I ask is the return temp going back to the boiler is only about 7-10 degrees cooler than the supply temperature. Does that seem right?
As far as heating the house goes, our system works VERY well. It just seems a little odd that theres such a small temperature difference from supply to return. We aren't living in the house yet, so I can't say how the DHW works. Hopefully by the weekend I will have the rest of the plumbing done and we can start moving in.
