Hello - I've decided to install a recirculation pump after years of waiting nearly a minute for hot water to reach the master bathroom. I've purchased everything I need and was looking over our new 75-gallon Bradford-White water heater for placement of the dedicated return line. The drain line seems to be the most mentioned location, based upon my on-line research, for returning the cool water, but I noticed the new tank also has a space heating send and return. The space heating return is in a better location for a cleaner, easier plumbing install of the return line, but there's a sticker just above the return that states "For Space Heating return ONLY"...so I tend to take stickers like that seriously (see attachment). The manual doesn't give any details. My question is - can I plumb to the Space Heating return line instead of the drain valve without causing problems? It would seem to me that the water would going to the same place as if I used the Tank Drain input. Thanks for any input on this...
