EcoInnovation Technologies in Quebec has just come out with the ThermoDrain, a residential model that outperforms all the other drain water heat recovery units on the market. Why is this important? The cost of copper is directly related to the price of the unit. If you take a look at the price versus efficiency, nothing comes close to the unit I picked up. The ThermoDrain is 52% efficient and is 40 inches long. A 40 inch Watercycles unit offers 36% efficiency. The savings difference between 52 and 36% turns out to be $120 a year for my family. When comparing the ThermoDrain with the POWERPIPE, in order to get 52% efficiency from a POWERPIPE, you need another $250 and another 25 inches of heat exchanger. Good luck! I picked my unit off of a representative listed on their website. Not to mention, they were very helpful in answering my questions. Cheers!

I just found your site through the Star article. Thought you might be interested. My husband and I just finished doing our own green build also in Toronto (Birchcliffe/Beaches area). Just moved in at the beginning of August. You can take a look at the blog if you want to see some of the issues we encountered. (many many many!!) The house has everything from passive solar and cooling to infloor heating, super insulation, solar panels and next year we will likely be installing the green roof. We actually installed two Powerpipes in the basement. The technology is really very interesting not to mention Canadian. I don't know the overall effect on the water heating yet (still too new) but it doesn't affect our pressure at all! Good luck with your project! Just remember, if something can go wrong, trust us, it will! Hi there!

I'm going to update the post to reflect these clarifications. You're definitely correct about the efficiency; 30% is the minimum. The length requirement is actually stipulated in the Energy Star requirements, under Table 3.12.1 "Fuel Savings Credits". The Energy Star documentation can be found here: www.360winnett.com/wp-content/uploads/2008/08/ESNH%20Technical%20Specifications%20Version%203%200%20April%202007.pdf Hey Vasile – good catch… I’m going to update the post to reflect these clarifications.

As per http://oee.nrcan.gc.ca/residential/personal/retrofit-homes/retrofit-qualify-grant.cfm the minimum efficiency needed for federal rebate is 30% (for over 43% you get more money back). There is no requirement for the length. The Ontario rebate is based indeed on length, and starts at 75 cm. Am I missing anything? Vasile Hi!
