I have a bell & gossett NBF-22 (.8 amp. 92W) pump. House is old 5 bath with new "L" grade copper pipes. Just insulated them with 1" wall foam. Seems the water heater cycles on more with the pump than when it was just gravity fed.
1. Will this pump cause me to use more gas to run the water heater?
2. If I turn the pump off will it still circulate with gravity or will the pump prevent a gravity recirculation?
3. Can I put a bypass around the pump and only use the pump at nite right before the kids take baths, then turn it off and just open the bypass?
Thanks
