Here is an idea

If you say connected the supply and return mains left two closely spaced takeoffs for the injection system .Have a circulator for the mains ? is this necessary . Hook up your two injection line to the takeoffs left off earlier , an injection loop and your off to the races .

Do not shoot me if this topic has been addressed earlier ,but here it goes . Has anyone ever used injection mixing to interface a replacement boiler with a gravity system ?. With that in mind a person providing that they did a proper heat loss calculation , could use a significantly smaller boiler perhaps 1/3 the size of the original.Even standing radiation which is generally oversized can provide proper Btu output at much lower tempuratures . I guess what Iam getting at is that injection mixing can be effectively used in other applications than infloor heating .

Why yes, my very observant fellow

Injection systems used in the correct why can help with a host of projects, including one we are working on now to solve cold returns for a church with 2 EK System 2000 in series. What exactlly did you have in mind. We use injection on most of our remodels/conversions from steam to HW radiators. This also helps to be able to control the temp to each radiator.

Can Do

Could someone please explain what an injection system is? Sorry but I'm new to this stuff. I really like this website, learned quite abit and am looking forward to buying some of Dan's books.
