Looking for small circulating pump/motor

Looking for small circulating pump/motor

PostBy: JJLL On: Mon Mar 31, 2008 9:19 am

Hi everyone,
I have a water coil in my stove. It works well, but I like my water HOT !

My stove is a little over 10 ft. away from my hot water tank so I'd like to install a small circulating pump/motor. I'd even go for a motor/pump with a variable speed controller, now that would be nice!

If anyone can post a link or give a suggestion on a good small one, I'd appreciate it.

Thanks!

Look on ebay or Google search. You might need an aquastat or some type of termostat control. You can just throttle it down with a ball valve.

Taco or Bell & Gosset BRONZE type pump since it is an open system (feed water from you water supply).

Thanks for the link. Due to the model shown in the link above, I've done a little more homework. Here's a link to a "Circulator Pump Buying Guide"

It's informative and may be helpful to someone looking to slowly pump hot water through their house.

You can add an aquastat to shut off the circulator if the temperature drops below a setpoint (120 degrees) at the outlet side of the coil in your stove. It will save electricity and wear on the pump by stopping it if the stove isn't at a high enough burn rate. A gate type valve is recommended for slowing the water flow through the coil or loop. If the water circulates too fast it will not have enough time in the coil or loop to absorb the heat from the fire.
My question is: What GPM rating is correct for a pump to circulate the water through the SS loop on my Alaska? I would "guess" that the smallest pump would be correct, then again this is a guess. I'd rather ask the question here then buy too small a pump or waste $$$ on too big a pump.

Thanks.
