I also notice that after a shower it only takes a few minutes before the water coming out of the hot water tap is cool again - that suggests that the heat in the water line is being quickly absorbed by the ground. So hot water recirculation in a Villages house would really be better described as underfloor heating which would probably add a lot to your hot water heating bill.

Take a look at my post. It's a pump but it really does not recirculate.
You press a button and teh pucmp activates and very quickly you get hot water. It boasts that say you wake up in the morning press a remote and by the time you get to the bathroom the water is hot. I'm going to check reviews of the product as it may be worth while
