Which direction?

From your statement that you never heard of a Munchkin, I'm guessing that you are new to The WALL. "WELCOME". Remember, the only dumb question is the one that doesn't get asked

    Which direction?

    Where should the amtrol expansion tank be located? Return or inlet pipe. Also where should Bell & Gossett cirulating pumps be located? Return or inlet pipe? Thank you

    Most contractors ...............................................

    put them anywhere they can fit them with the pumps on the return, pushing in to the boiler. People who know what they are doing (wallies especially) put the pumps on the supply and "Pumping away" from the expansion tank. Mad Dog

    Pumps and such

    I think the B&G's go in the trash don't they! Just joking, sort of. Pump on the supply side after the expansion tank. If you install a Taco Vortek air seperator or similar other branded product, it has a tapping on the bottom for the boiler makeup water line and the expansion tank that makes the whole process easier.

    Pumps definitly go on the return pumping towards the the boiler and the tank is typically on the water inlet pipe. The thing about boilers are they all seem to be uneak to whoever put it in. I have seen a few old boilers call Triad that resemmbles a hot water heater and the pump went on the supply line leaving the boiler and pumps away from the boiler.

    The only time that your statement is correct is for a high head boiler like a Munchkin/Pinnacle, Ultra or another high restricted heat exchanger. I love coming to a house and hearing a circ. mounted on the return desintegrating as it it is trying to pull a slug of air down the pipe and try to push it into the bottom of the boiler. Once I cure the noise problem (relocate the new circ. to the supply)and show the customer reason for the cure in my copy of "Pumping Away..." I have a customer for life, who is telling their freinds how wonderful I am.

    We oviossly work in different areas of the country. I've never heard of a munchkin or pinnacle. We work with Lennox or Raypak or Dunham Bush and The only time the pump is noisey is when there is air in the system. These are residential units. Does any one else have an opinion on this. I've been to boilers where the Bell Gossett pumps are 25+ years old. Also Amtrol makes an expansion tank that has a built in water feeder.

    The laws of physics apply no matter what part of the country or the world you are working in (even space). You might want to pick up a copy of "Pumping Away ..." in the books and more section of this site. It will give you some food for thought,if not a new perspective on piping hydronic systems and the way they operate.Years ago I started with that book at a seminar ,ended up buying the whole collection. Dan has a ability to make even physics understandable and usable.

    There is no right way to do things wrong...

    You can put the pump wherever you think it should go, but it WILL work properly if it is pumping away from the expansion tank connection, not TOWARDS the expansion tank connection.

    Trust me when I tell you that there is a right way and wrong way of doing it. Buy Dans book named Pumping Away and you too will have the answer to life...

    Your life becomes less complicated, your customers find out what a truly silent heating system works like, the sun comes out, birds start chirping, and on and on.
