1st season using a water coil in my Keystoker and all worked very well. One question I have is about recover times. I currently use thermosiphon method and recovery times are very long if we use all of the water. This doesnt happen often but when it does it can take approx. 10 hrs. to come back up to temp. completely. My question is, does anyone think installing a pump will help recovery time? I'm actually happy with the way it's working now and if it's not going to help much I won't bother. Just wanted some opinions.

Some details please. Is this a boiler or stove? How big is the tank? How does the water flow?

Yes, it should help but don't use a big pump and you should have a way to throttle the flow.

You can also add another coil if you want. No reason to just use one coil.

I gave that some thought, but after a little more thinking I don't know if this will help much. I think the water coming from the coil is plenty hot enough because the water flows so slow. Actually to hot until I plumbed it through the NG tank. That being the reason for the long recovery times. Water temp really has not been an issue whatsoever, it's just the recovery time. This is one of the reasons I was asking if a pump may help. I would just find a pump and still add a valve to throttle it down if needed. I'll start checking the flow rates of some of the bronze pumps. Should I go with a Taco 007 or find one with a slower flow rate? I've got another idea now but that will wait until I see how this works out. Thanks.

What diameter is the coil and plumbing?

Water lines and coil are all 3/4"

The TACO 007 should be fine.

A "common" 007 should not be used. Domestic water calls for a bronze pump. A 006 bronze will do the job and is $100 cheaper than the 007 bronze. That being said, I don't think it'll make a huge difference, not if under most conditions it's doing the job by gravity. You'll need more than just the pump, you'll need some electrics to tell it when to turn on & off or you may overheat. I'll guess you'd have $350 in the project & it'll be a long time before it pays for itself.

I aleady planned on the other parts I'm gonna need to use a pump, also a bronze as I stated above. I was more concerned about wether it would help or not. I may have to leave it as is for now anyway, just lost my job yesterday due to lack of work. Got more important things to worry about now. Gotta keep the head held high though. It will get better sooner or later. Thanks everyone.
