quick question on installation.  Does it matter if I swap the inputs, ie, instead of going in A1 and coming out A2 for the hot water, can I go in A2 and out A1?  I wouldn't think it would matter if the insides of the exchanger are the same. 

If not no big deal just trying to save some labor and rework on my layout.

Input and output doesn’t matter as long as you have a cross flow, IE if your boiler water comes in one end you want your domestic water to enter the other end and exit the end your boiler water enters, this gains the most heat transfer.

Make sure it's plenty big enough! Bigger is better! And plan on putting some boiler drains so you can back flush it  to clean it if you have to!

Am sure you are 100% correct but the wording got me lost (not your fault) could you draw something to explain this so I can get it right? Thanks

You just want flow going opposite directions.

Braveblast - I hope this helps to visualize what they are saying.  Roger

well done Roger!

Thanks.  I'm learning from a good teacher.

For some people, me included, pictures are worth more than 1000 words.  Roger

He is a pic of what I did , better to have your return line going back to the boiler on the bottom  less chance of sediment dropping off in the exchanger
