good looking rig, my only problem with setups like that that have one engine to run 2 or more pumps is if the engine quits, blows up, or starts stuttering and missing then your down for good. Yes its more economical to have one engine turn 2 pumps however I feel better knowing that we have a backup if one machine goes down
Nigel, is that your rig?
that is sweet! I think im leaning more twards what chris is saying. one coil,then wrap another coil over that losts on insulating and the water will stay in the heat longer giving you more heat rise.but side by side (6'wide) i will look him hip chris thanks how was the RT?
