The Power-Pipe is a great product with good returns on the investment. It makes environmental and economic sense. We now provide installation services for the Power-Pipe and would be happy to help anyone interested a quote!

We decided to go with the pipe model, similar to the one pictured above. We’ve got enough room to place it and it is much cheaper than the gutter model.

Just two quick links to pages with information about the gutter shower heat exchanger. I apologise the sites are in Dutch, but the pictures and specifications should speak for themselves:

Thanks Quinny! We love readers with suggestions, and we are not saying that the Power Pipe is the only option out there. It would be great to hear what you decided on for your house. In fact, you mentioned a shower gutter product that I’m not familiar with – sounds interesting!

Just trying to give accurate information/corrections.

One of these things is in the plans for our new home. I’ve got quite a bit of information from several manufacturers of shower heat exchangers, including official test reports about efficiency.

Hi Quinny! Astute observation – yes it seems that this would work best for showers, and would not necessarily be beneficial when draining a bathtub.

Better use it on the shower drain pipe.

This only works if you’re letting hot water flow down the drain while using hot water. If you’re draining your bathtub you’re not likely to be using hot water at the same time (you’ll be drying off and putting on clothes). You’ll just heat up the heat exchanger and let it slowly cool down…

Unless the shower is in the bathtub, of course…

There are other models of this thing too, by the way: in the form of a shower base and a shower gutter.
