Hot water heat recycling (also known as drain water heat recovery, greywater heat recovery, or sometimes shower water heat recovery) is the use of heat exchanger technology to recover and reuse hot water heat from various activities such as dishwashing, clothes washing and especially showers. The technology is used to reduce primary energy consumption for domestic water heating while also reducing greenhouse gases. Standard units save up to 60% of the heat energy that is otherwise lost down the drain when using the shower.
The technology is fully recognized in Canada where the federal ecoENERGY retrofit for homes program offers grants for installations and the EnerGuide for New Houses program has energy savings and energy credit calculations that it uses for new home construction.

Check fine print before buying plumbing fixtures
Out of Victoria and Calgary come these reports of regulatory woes endured by homeowners, one of them putative . . .
That plumbing fixture sitting on your local retailer's shelf might come with nice packaging, an attractive finish and sleek styling, but does it come with a stamp of approval from the Canadian Standards Association?
It might not, but B.C. retailers can still sell it and plumbers or handy homeowners can install it, but don't expect your local building inspector to approve it.
That's because the province requires plumbing fittings and fixtures to comply with CSA standards, but do not monitor or control their sales.
Debbie Hellbach didn't know that. She expected to have a new bathroom, laundry area and living space at the end of her four-month $60,000 basement renovation. Then she got a City of Victoria notice telling her that her new sinks and faucets did not pass inspection.
"I never expected this," says Hellbach as she looks over her new stainless steel one-piece counter and sink in her laundry space.
The fixtures work, but did not pass inspection because they failed to display Canadian quality and safety standards imprints or markings, as set by CSA or one of about seven other certification bodies such as Underwriters Laboratories (UL), American National Standards Institute (ANSI) or the International Association of Plumbing and Mechanical Officials (IAPMO).
Hellbach isn't alone. Brian Husband, the City of Victoria building inspector who issued her the failure notice, says that somewhere between five and 10 per cent of all plumbing inspections fail for the same reason.
Ralph Suppa, president of the Canadian Institute of Plumbing and Heating, says the sale of plumbing parts is not regulated. That leaves it to the consumers to double-check fixtures before they purchase them. Suppa points to the global marketplace as one source of the problem.
"A lot of offshore products are coming into Canada, and there are some that may be blemishing this industry. We're trying to work with regulatory agencies to help stop the sale of non-approved plumbing products, but there's not enough people to go around to do these jobs," says Suppa.
A second, albeit much smaller problem, is the sale of counterfeit parts, or foreign-made products stamped with certification that, in fact, have never been examined by a certifying agency. Husband says this problem is rare. When CSA publishes a standard, its enforcement is voluntary, says Anthony Toderian, senior media relations officer at CSA's Toronto office.
"It's up to the provinces to decide how to apply those standards," says Toderian. "In some jurisdictions, the code would be slightly different."
And from Cowtown . . .
Two feet. Two lousy feet.
That's all that's keeping Trish Hennan and her family from moving into their dream home.
The night before Trish, her fiance, Grant Stewart, and their two young children were to take possession of the new home this summer, they got a call from the developer.
The company, Cardel Homes, told them the home had been built 60 centimetres too close to the neighbour's property.
Not all items sold by B.C. retailers have the CSA stamp, which means a building inspector won't approve it

The result? They couldn't move into the spacious, $462,000, three-bedroom home they'd spent months waiting for.
"We thought it was a joke," Hennan, 30, said. "It has to be a joke."
"It was going to be a nice house," she added, rhyming off its specially chosen features, from the heated bathroom floors to the built-in central vacuum.
To move it two feet, the house would have to be lifted up and set in the backyard, the foundation destroyed and then rebuilt in the right spot.
"Our survey company made a major mistake," admitted builder Don Stouffer, regional president of Cardel Homes. He said the mistake was a first for Cardel Homes, but not an uncommon one.
Because of a booming construction industry in Calgary, the earliest a company would be available to move the house is January.
Cardel Homes asked the city for "relaxation" -- permission to leave the house where it is -- but were told that wasn't likely.
So the family's in limbo. Since July, Cardel has been putting them up in another property it bought, about four blocks away.

Giving foreclosed properties a clean start
Rick and Kim Melhem, from Pen Argyl, fixes up homes and resells them. This is a historic house at 1248 Howertown Road North Catasauqua . (MONICA CABRERA, Allentown Morning Call / September 23, 2007)
Rick Melhem of Pen Argyl buys properties in foreclosure, fixes them up and then resells them.
He prefers whole house restorations to additions or room renovations. There's a greater feeling of accomplishment, says Melhem, who has done all kinds of construction in his career.
Melhem started in the business, working for his father-in-law, who was in the construction trades.
''He did a lot of high-end commercial work,'' Melhem says. The work required a lot of traveling to New Jersey and New York.
Wanting to travel less, Melhem started Realty Investment in 1983. He does about four or five homes a year.
Melhem jokes that he started doing flips before the Home and Garden Television channel made them popular.
The house he recently restored at 1248 Howertown Road in North Catasauqua is a little more elaborate than his typical flip. He usually does everyday properties that are distressed.
He says competition for such properties has heated up recently, possibly thanks to the television programs.
''You used to be competing with four or five people, now it's like 60 to 70,'' he says.
The house Melhem recently restored on Howertown became a family affair. Melhem's wife, Kim, chose all the lighting fixtures, kitchen appliances and bathroom fixtures.
She selected antique looking lights so they would match the decor.
''The electrician gave her a list of places that had antique fixtures and she didn't buy more than two at any one store,'' Melhem says. ''She definitely spread the wealth.''
Sons, Josh and Ryan, college students, helped with the construction over the summer.
Everyone in the family, including daughter, Chalice, fell in love with the house. ''For a brief time,'' he says, ''we considered buying it for ourselves.''

What is a Ball Valve?
A ball valve, one type of quarter turn valve, is quite literally a ball placed in a passageway through which fluid flows. The ball has a hole through it, by which the valve opens and closes. When the ball is positioned so that the hole runs the same direction as the passageway, the fluid simply flows through the hole, and the valve is open. However, when the ball is positioned so that the hole is perpendicular to the passageway, the fluid cannot pass through, and the valve is closed. The ball is controlled from outside the valve, often with a handle that is turned 90 degrees, or a quarter turn, back and forth to open and close the valve.
The basic ball valve, described above, is a two-way valve. This ball valve has a single, straight passageway bored through the ball, making two openings: one on each side, an inlet and an outlet. A ball valve can also be a three-way valve if a third hole is bored partially through the ball, until it meets the main hole, forming a T. A three-way ball valve can shut off one or all of the three passageways it connects.
Because of the nature of the ball valve, it does not work well in situations in which fine control of the valve is needed, such as the valve that controls the throttle in a car. However, a ball valve works very well for situations in which a flow needs to be completely shut off, such as the shut-off valve on the main water line in your house. Ball valves also do not tend to develop problems if they are not used for long periods of time; they will still work perfectly when needed again.
There are three different types of ball valve. A full port ball valve offers no flow restriction, which means that when the ball valve is open, the liquid can flow freely through it. This is achieved by making the ball larger than the passage size, so that the hole bored through it can be the same size as the passage. A standard port ball valve does not have an oversized ball, and as a result the hole is one size smaller than the passageway. This presents a small amount of flow restriction as the fluid passes through the ball valve. A reduced port ball valve, on the other hand, has an even smaller ball and an even smaller hole, which creates significant flow restriction as the fluid passes through the valve.
