Use 1" valves and enlargers to 1-1/4".

It will work.

Thanks McGiever for ALL of u help. As 1 inch is cheaper than 1-1/4 and I wilL be back with more dumb questions soon THANKS AGAIN

The price of 1" valves and reducers may be the same as 1.25" valves. Check before you purchase.

Your piping questions would be easier to understand if you could post a diagram.

Thanks Rob I will check. As you know I am I new to coal heat and was looking for help to install my AHS 1-30 with out a lot of knowledge when I found this forum. What I have learned has been from reading here thanks to you guys. But I am also new to this forum and asking questions, so if I do anything wrong I hope you will forgive my mistakes and help me learn. I have no idea how to post pics or diagrams but I will try and read about it and when I learn how I will post as needed. I will be happy for any and all help with this forum and the installation. I have learned a lot from you guys but I know a little knowledge is dangerous, but I am trying Any help here or in E-mail or private messages will be approached

THANKS Ron

You can feed 3 to 4 zones from the 8 GPM (80,000 BTUH) that a 1" type M copper pipe can easily sustain. And if pressed, it will carry 100,000 BTUH without velocity noise. Perhaps 1-1/4" pipe is not necessary.

Thanks lsayre,
As of now I have a 1-1/4 inch copper loop running part way around the basement about 30 ft. then it splits & the 1 1/4 runs left and the right at the split is 1 inch copper and was set up for a gas boiler 50 some years ago, then an instant elect boiler was installed and now I am installing the ASH S-30. What I need to know is since there will be 5 zones, 10 valves and 5 pumps and the pumps will be close to the boiler "pumping away" can I go from 1-1/4" pipe to 3/4" valves then back to 1-1/4" pipe at the valves then into the zone loops?? BTW ill get to the GPM and BTUH and the elect hook up MUCH LATER!!!! If I live that long. as I said I am old and slow to learn as well as do!!! THANKS AGAIN

Yes, you can branch off of the 1-1/4" with 3/4" zone legs and return them to the 1-1/4".

It would be pretty unusual to have 1.25" zone piping unless it is a monoflow system.

Not sure what a monoflow system is, but I do know I have 1-1/4 inch copper loop running part way around the basement about 30' then it splits & the 1 1/4" runs left and the right leg is 1" and then both loops return to the boiler, smaller pipe branches off to each baseboard then returns to the main loop. I made a diagram of what I want to do and I hope u can tell me if it will work if I can add it here.

What is the difference between M & L copper pipe ?? I think I have some of both in my system dose it matter?? Seems to me the old is one and the new is the other.

Wall thickness. You don't need much of it for home heating applications.

Thanks lsayre. What one is thickest and is the thin one ok to use for baseboard hot water heat ? I hope so as I think I have some of both .

From memory type M is the thinner of the two. It is universally chosen as the right one for hydronic heating. My house has had it in use since 1964. When I tapped into it during my boiler install I did notice that it is a bit thinner walled than fresh and new type M, so 46 years of use did thin it a bit.

Thanks again seems as if that is one less think for me to worry about as I think the older pipe it thicker than the new I bought to s[lit the loop into zones THANKS AGAIN All your help is appreciated now ill start the manifold and the zones going to get it all laid out the cut into the old supply and return loops
