I would like to re-pipe my current boiler setup from 1/2 to 3/4. The supply from the meter is 3/4 copper pipe. For some reason it was reduced to 1/2 for everything in the house including the feed to the boiler. I would like to re-pipe the system so that the boiler will be fed by 3/4. Attached to my boiler is a hot water holding tank. In between the two is a circulating pump. All of this is currently piped in i/2 copper.
My goal is to feed the brand new high flow shower with 3/4 copper.
the cold was easy, all I had to do was tee off the main and run a dedicated line to the shower mixing valve.
The hot is obviously more difficult
So far I have been able to run a dedicated 3/4" hot feed from the top of the hot water tank to that shower mixing valve
My problem is the boiler and hot water tank is all fed by 1/2". This is what I would like to correct
The pictures show the boiler and circulating pump and tank
the pump is a little giant model # CMD-1003B
The hot water tank a Rheem model # 666H-300
I think I will need a different pump because this one only has 1/2" connections. Or does the pump matter?
The boiler is no problem, there are 3/4" connections that can be utilized on that
The hot water tank has 3/4" connections on the top, but the bottom nipple where the pump is connected is 1/2". Does this mater? Will that pump affect the pressure and volume, or does it just circulate when needed.
Like I said, My goal is to feed that new high flow shower with a dedicated 3/4" hot water line.
The rest of the house I will be leaving on 1/2"
Does this sound like it can be done?
Can you offer me any advise or opinion on this?
