AutoCirc1 or AutoCirc2 anyone?

18 years ago

Our 10 year old home has a circulating pump that was not installed correctly and therefore never worked. When the motor burned out on it we never repaired it since it never made a difference when it was working. In our master bath renovation we learned that there was no return line and therefore the hot water was pushing against closed taps, which delivered no hot water and is what burnt out the motor. I could make a list of stories like this about this house, but that is another post!

We have a large home with many bathrooms and it takes a long time to get hot water anywhere. The new plumber gave me a brochure on a new system sold by Laing called AutoCirc (there are 2 models) that does the same thing as a circulating pump but requires no return line so can be retrofit. Anyone have one or know of this? He has never installed one but is capable and I am intrigued. Thanks!

I think this is the one you want (see link). I'm considering it as well, since I have a similar problem with no return line.

It goes under the sink in the farthest bathroom. You'll need an outlet for it to plug into.

There are similar devices made by Watts and others, but this Laing unit seems to get the best reviews.

My only concern is the degree to which you'll be paying a lot more energy costs by forcing the water heater to work more. Of course, that has to be weighed against the lost water (which you once paid to heat) costs and the value of your time/convenience in waiting for hot water.

Definitely get a version that includes a mechanical timer so you're not heating water all night.

Since posting I have found some info online (complete with mixed reviews) at Home Depot's website. The brochure I have (from my plumber) describes 2 versions, the autocirc2 being a valve AND pump system, and not requiring a power outlet at the source and autocirc1 being the one that sounds like you are describing. Version 1 is installed at the sink, Version 2 at the hot water heater and the sink.

Hopefully someone here HAS one and can post their actual experience. I hate being a guinea pig!
