subhead faqs

   1. What does a drain water heat recovery pipe do?
    A drain water heat recovery pipe is a simple technology to save on energy used to heat water. This pipe takes advantage of the warm water flowing down the drains to preheat the water going into the hot water tank. Preheating the water reduces the amount of energy needed to heat the water to the set temperature.

The heat is transferred but the drain water never mixes with the fresh water. Cold water coming into your house runs through a series of coils that are tightly wrapped around your drain stack. The heat from the drain water is transferred through the copper walls of the heat recover unit to warm the cold water before it goes into the water heater.

 2. How do I determine what the Heat Recovery Efficiency is for the pipe that I would like to purchase?
    The efficiency of a drain water heat recovery unit is measured by a value called the Heat Recovery Efficiency, which is expressed as a ratio between the actual heat transfer and the theoretical maximum possible heat transfer.

Natural Resources Canada’s website allows you to search drain water heat recovery models. After selecting the size required, choose high heat recovery efficiency models, as these are the most efficient.
   3. I applied for and received a rebate for my present home which I have now decided to sell. Can I apply for another rebate for my next home?

Yes, provided a Drain Water Heat Recovery rebate has not been issued for that location, you can apply. Each rebate is tied to the location identification number of the residential address and tracked through a Service Order.
