Having a Weil-Mclain EG boiler installed....old piping doesn't seem correct?
Hi guys, I'm a newbie to the forum. I have an appt with a contractor to install a new Weil Mclain EG-30 boiler installed. The boiler being replaced is the identical boiler. My concerns lie with the way the original boiler is piped. I have included pics of what I'm working with. From my research I have a counterflow system because there are no wet returns at the end of the mains. I did have some water hammering with the original system. I also do not have a Hartford loop but I've read it's not extremely important with a dry return system (counterflow). Can anyone tell me whether or not the near boiler piping is designed okay?
