Hello All,
Here's the deal : Bradford white 65 gal hw heater. Hot side has tee, the branch goes to mixing valve and dropped down to 120 for fixtures. The run on the tee goes directly to dishwasher and heating coil of air handler (ac coil bottom) heat coil on top. I've been tasked with figuring out another guys work. This is all new, and 84 units done this way. The original plumbers didn't install any draw off, gauges, etc. Purging is done at coil inside air handler. With tstat on heat (but off) my max temp was 135F. With the tstat calling and pump on, temp is a little lower. The tstat on hw heater is on the max setting both elements. Reset is fine. I can't seem to get the heat coil temp up. Side note, runs r kind of long, uninsulated, and done in cpvc. At one point I threw testers on the element and it was getting power. Threw the disconnect and ohmmed it out, read around 10 ohms. Any ideas, or could I really be having that much heat loss from the run and it being uninsulated? Any clearifications would be nice. Please bear in mind I'm an apprentice trying to learn the right way and fixing somebody else's handy work so go easy on me. Thanks for any help!!!!
