About This Product
At 20-30% of home energy consumption, water heating is typically the 2nd highest energy demand. The Power-Pipe can dramatically cut water heating costs and reduce total home energy consumption by 5-10%. It works by using outgoing warm drain water to pre-heat incoming cold fresh water so your water heater doesn't have to work as hard. The Power-Pipe will typically pay for itself in as little as 2 years, and may qualify for Government or Utility grants. The Power-Pipe's performance has been tested in accordance with the CSA B55.1 standard and independently verified by Intertek. The Power-Pipe is safe for drinking water, requires no maintenance, has no moving parts, increases effective hot water capacity, extends water heater life, and can be used with any type of standard plumbing system and comes with a 10 year warranty. Furthermore, Power-Pipe technology is proven, practical, affordable, and in use in many thousands of homes. A Power-Pipe will reduce greenhouse gas emissions by up to 1 ton/year per household in the average family of four.

Questions & Answers
Can this be used on a Dryer vent?
Hello, No, it is not designed for a dryer vent. Thank you.
It seems like it could increase the amount of hot shower water (minutes) available from a small water heater tank. Do you have test results that can confirm the percentage increase in the water heater tank's First Hour Rating of gallons delivered?
Hello, yes it does increase the available minutes, however every case is different. Please contact info@renewability.com for more information. Thank you.
What is it made out of? What are the specs?
The Power-Pipe is made of high-quality copper DWV tube, manufactured in accordance with ASTM B306 and certified according to the CSA B55.2 Standard for safety and quality. The specs for the R4-48 are: Connection 3/4", Diameter 4", Length 48" Pressure loss 1.3 psi, 49.8% efficiency.
COPPER. MOSTLY PURE.
What size water line would this work on 1/2 or 3/4? I understand the drain pipe is 3", however the item description is not clear on water supply line size...
All residential (R-series) units connect easily to a 3/4 inch fresh water line. Thank you.
Can the drain recovery pipe be installed horizontal?
Hello, For the efficiency rating, the Power-Pipe is meant to be installed in a vertical position. It is possible to install it horizontally, however you would lose 1/2 to 3/4 of the efficiency rating of the unit. Thank you.
NOPE. But they make a horizontal model
If the idea is to extract heat from drain water as it falls down a vertical pipe, shouldn't it be heavily insulated? The copper water jacket will significantly radiate heat to the room without it.
If a Drain Water Heat Recovery unit is located within the heated space of the home, insulation isn't really necessary although it can't hurt to cover it if you choose to, as while a slight amount of heat loss may occur, it is only really happening when the shower or water flow is exchanging heat. On the other hand, if it is installed in an unheated space, I personally would recommend insulating the unit primarily to stop the formation of condensation, and secondary to minimize the potential for heat loss and or freezing potential depending on your climate and lifestyle.
What sort of drain line could a pertinent amount of heat be extracted from?
I believe most people use these on shower drains to warm up the cold water coming to the shower, so less hot water is needed to have comfortable shower.
The description says this requires a vertical installation. I only have access to horizontal runs of my house. Can this be installed horizontally?
yes but it cuts efficiency on half
In order to install this in that scenario you would need the assistance of a pump to pump the water to a vertically installed pipe
No, the drain cannot be installed vertically.
