Recirculation Pump

Anybody out there got any experience with installing a hot water recirculation pump ?
It's s small pump forcing the cooled down water in the hot water pipes back into the water heater, to avoid running the tap before hot water comes.

No experience, other than a bucket in the shower

But I like this invention.

Saves lots of plumping and wiring costs that some of the other systems that are around need.

And it's Australian made too - even better

Interesting Yak,

Whats the payback time on something like that?

Whats the initial cost?

I knew about the Dux (http://www.dux.com.au/recirculation.htm) and Autocirc (http://www.carhil.com.au/autocirc.htm) pumps. Thanks for the third one Steve. Now I'll have to find out which one will suit best....

Well they say up to 10% water saving on the web site.

The basic unit is $487 and the mixer model is $838.

So if you work out 10% of your annual water bill that would give you a best case payback period - and maybe 5% as a worst case - and you'd find out your payback period young Matt.

Remember it is a long term product.

But more to the point - it stops wasting good fresh water and if your in Brissy on Level 6 water restrictions, (which they may well soon be) :shock:

it would give you a bit of water every day on to your prized vegie garden without even having to bucket it out from the shower or kitchen.
