What to buy. (replacement circulators)
Well it's getting to be that heating time of year and I'm up to my arm pits trying to figure out which circulators I should install to replace these existing power pigs.
I want to be able to run the circulators all the time and I'll have an outside air reset installed to modulate the water temperature. I'll tell you for the average joe, not a dumb one, but just the average joe figuring this sizing thing out for me has been a challenge. Maybe I am over thinking things can you guys can help me make this simple.
1. I just want to replace these two B&G 1/6 horsepower models with something that will still run at set speeds, but will use less power. Again, I want to use these circulators running all the time.
2. The pipes that serve the circulators are 1 1/4 and are connected to larger cast iron. This is a gravity conversion of a system that was put in about 1905. I see from Dan's books that you can run about 14 GPM through 1 1/4 pipe. Right now there are two zones and the stats only shut down the circulators. Later I will be changing that.
I have looked at various pumps like the Taco bumblebee and the Alpha, but I can't seem to figure out which is going to work best. Any help you can provide would be MOST welcome! I've been at this for a day and I need to move on.
