That's correct, Series is to be used when the 2 heaters are not the same. BECAUSE they cannot be in parallel.
But 2 WH's that ARE THE SAME CAN BE EITHER WAY. Think about . Why would they have to be different.
I won't even try to get it through to you any longer. If you don't get it now, you better call the the people that wrote it.
You keep using a lot of words but are not saying anything different. I can't even make myself read that stuff you're writing. If you don't understand the basic concept, no amount of incorrect examples is going to change anything. You seem to keep repeating stuff from the article you read but obviously don't get the basic concept.
Do us both a favor and please call the manufacturer. Peace!
Do not understand the personal attack when what I said is that you can hook them up any way you wish.It says parallel is to be used when the 2 heaters are the same. Series is to be used when the 2 heaters are not the same. The language is clear to me.
one system [parallel] draws from both heaters
one system [series] draws from one heater, and uses the largest heater as a tempering tank.
You can hook up the water heaters any way you wish, and they will work, These are just recommendations for getting the best efficiency out of the system
the Reason, that the in series piping diagram shows the 2 to be of different sizes is for efficiency
that is a undisputed fact confirmed by the Ruud co.
