Paris mosque slams burger chain's Muslim outreach

fj12021 — Mon, 06 Sep 2010 11:36:39 +0000

PARIS — be aware to huge firms hoping to tap into France's lucrative but long-neglected Muslim customer market: Pitfalls may await, and never just through the kind of complaints through the far-right.

As with this week, 22 outlets of selected French quick foods chain fast are serving burgers it says respect Islamic dietary law. as well as although countless Muslims are delighted, the effective major Paris Mosque complained Thursday that Quick's conditions aren't all-encompassing enough, and how the operation is meaningless.

Quick's meat is licensed as halal, but Cheikh Al Sid Cheikh, assistant toward the rector using the Paris Mosque, mentioned the burger chain will require to possess experienced another components checked as well, from its mustard to buns to fries.

"The relaxation should be validated too, or else there's no point," he informed The linked Press. fast responded that it has no intention of producing any of its restaurants halal through-and-through — beer is nevertheless served there, for example, mentioned spokeswoman Valerie Raynal.

Such social sensitivities are new territory for countless French companies. until recently in France, a country obsessed with secularism, firms experienced been hesitant to accomplish out to France's Muslim population, believed to acquire 5 million, the ideal in Europe.

Quick, the No. a few of burger chain in France right after McDonald's, could possibly be the most current set to key in the expanding French industry for halal food, which has an believed euro5.5 billion ($7 billion) in yearly sales, based on some evaluate by France's Solis marketing and marketing agency.

Both the Casino supermarket chain as well as the Fleury Michon collection of chilly cuts have halal offerings. The Paris Mosque has significant praise for Kentucky Fried Chicken France, which it says invested 4 weeks consulting with Muslim officials recently about its fare. The chain is really a rarity in that it has offered halal foods for several years — although it by no shows trumpeted the fact.

Part of companies' reticence may links of london bracelet are already political. Quick's announcement prompted a torrent of adverse commentary through the much right and through the relaxation using the political spectrum, with complaints how the business was forcing halal foods on non-Muslims. Only about 6 % using the chain's outlets have gone halal.

The brouhaha greater compared to burgers follows a debate on burqas, which France is preparing to ban — a mark using the country's insistence that integration could possibly be the only course for its minorities.

Beyond the political chatter, the Paris Mosque's response highlights disagreement amid France's Muslims about what dinners are severely halal, who is certified to decide, and whether or not the qualifications businesses are rigorous enough in producing specific that animals are slaughtered properly.

Halal meat should appear from animals that are already wiped out with a reduce toward the jugular vein. The animal's mind is pointed toward Mecca, with one another with a blessing is recited.

Fateh Kimouche, founder using the French Muslim customer internet website Al-Kanz, says most using the 40 to fifty outlets in France that provide halal qualifications aren't rigorous enough and don't have their individual inspectors to confirm that Islamic law is getting respected.

He says the circumstance is scandalous, calling it "halal-gate."

"Up to 90 % of meat marked 'halal' isn't really, and there are huge names in French market which could be as a good offer as their necks through the problem," he said.

Beyond that concern, he says Quick's choice is steering to be considered a wake-up call up to huge business about how important the halal industry is in France. Quick, for its part, says business has doubled in current weeks at eight outlets which have previously attempted the concept.

=discount ugg boots A.O. Smith

qwpn0363 — Mon, 06 Sep 2010 08:44:04 +0000

Several reviews and plumbing forums agree that Bradford White water heaters have the best reputation for build quality and rapid repairs. Rheem/Ruud, which also makes water heaters under the GE, Marathon and Richmond brands, comes in a close second. One of the largest water heater manufacturers, A.O. Smith, makes some very energy-efficient water heaters under its own brand name, as well as Kenmore, Whirlpool and several other water-heater brands. However, contractors rank A.O. Smith water heaters well below average, and owners reviewing Kenmore and Whirlpool water heaters agree.

Reviews suggest checking with a trusted plumber as the best way to make sure repairs will be swift and cost-effective. Some energy-efficient water heaters use circuit boards that are easily damaged but require replacement, making these water heaters very costly to repair. Other models may also require special-order parts that delay repairs; meanwhile you have no hot water.

Designs, costs, and local incentives vary tremendously across the country, but we found the best guide to calculating payback rates at FindSolar.com. Solar hot water heaters are tested and rated by the nonprofit Solar Rating and Certification Corporation (SRCC), and the Solar Roof Skyline kits get enthusiastic coverage at the U.S. Department of Energy website. Our Useful Links section contains many links to more information about solar hot water heater designs and options.

Water heaters have to meet certain minimum standards for safety and energy efficiency,discount ugg boots, and pricing for most water heaters varies regionally. It's not surprising, therefore, that most expert reviews provide guidelines on choosing a water heater, but don't rate or recommend specific brands or models. Consumer Reports magazine, for example, doesn't rate specific water heaters against each other, but editors do provide a helpful cost comparison and discussion about payback time if you choose a tankless water heater tesy iwh over a standard storage-tank model.

With many utility rates at an all-time high, interest in energy-efficient water heaters is increasing. New Energy Star ratings for water heaters kicked in on Jan. 1, 2009, so you'll now find Energy Star-rated gas storage and tankless water heaters. That same month, GE announced the first hybrid electric water heater,ugg ultra short, which builds a heat pump right into the tank-style water heater.

It's easy to judge water heaters only by their energy efficiency, price, or warranty length, but reviews say this is a big mistake. Warranty length can be a clue to the amount of insulation or other construction details, but both contractors and owners say warranty service is a lot more important. We found many hair-raising complaints from owners of water heaters with 12-year warranties. Warranties usually cover only parts, not labor, and most warranties are valid only for the original owner -- voided as soon as the house is sold. Some warranties require odd things like proof that a barely accessible lint filter has been cleaned every three months. Even a warranty still in force isn't much comfort if parts and technical support aren't available or there are long delays in obtaining them -- or worse, the tank leaks,lady gaga headphones, flooding your house.

We also found good articles at FineHomebuilding.com, covering all the basic water heater types, including tankless, solar and tank-style water heaters and various combinations thereof. A J.D. Power and Associates survey of plumbing contractors is valuable for ranking the three main manufacturers of gas and electric storage-tank water heaters, the most common type.

Federal tax credits for installing energy-efficient water heaters have been extended. You can get a credit for 30 percent of the cost of buying and installing a solar water heater for new or existing homes through 2016. Credits for up to 30 percent of the cost (up to $1,500) are also available for Energy Star-rated gas or propane tankless water waters as well as electric heat pump water heaters. A few storage-tank gas-fueled water heaters qualify, but they must exceed Energy Star efficiency quite a bit, with an energy factor (EF) rating of 0.82 (Energy Star guidelines require gas storage water heaters to have an EF rating of 0.62).

From Mark:
I’ve got a technique I have used in the past, with pretty good success, to reduce the open water exposure yet give a good drinking area for the horses.
I cut a board to cover the top of the tank. In that board I cut a hole that is the diameter of a 32 gallon plastic trash can. The hole is cut to the size of the trash can such that the lip around the top of the can will not go through the hole. These trash cans taper from the top to the bottom of the can (I imagine so they will come out of the plastic mold). I cut the bottom off of the can. I then slide the can (minus bottom) down into the hole that I cut in the top of the lid. The lip of the can stops the can from going all the way into the tank. I then screw the can to the top of the tank so the horses don’t pull it out. Next I fill the tank with water. Now the only exposed water area I have is the diameter of the plastic trash can. I then use the bottom of the trash can that I cut off as my floating cover. It fits in the top of the trash can pretty well because of the taper to the trash can and it limits my exposed water to only a small ring which is the diametrical difference between the top and bottom of the can. All of the horses quickly learned to just push against the trash can bottom to drink.

There has been a lot of interest in a collector that uses PEX tubing rather than copper to convey the heat transfer fluid. Here is a cut a collector that does this -- with careful attention to the PEX/fin joint, it can perform surprisingly well. This is a cut at a solar water heating collector that uses PEX tubing instead of copper to convey the heat transfer fluid. The fins are aluminum, and a lot of effort was put into attaining a good thermal bond between the PEX and aluminum. Testing indicates that the collector performs at 84% of and all copper commercial collector at about 1/7th the price.

This design was developed by the Davis Energy Group in an effort to lower the price of solar water heaters. The unique design allows more use of plastics resulting in a lighter and less expensive design. This is a soon to be commercially available, low cost, Integral Collector/Storage solar water heater.
The retail price for DIY installations is estimated to be $2200.

The collector has been SRCC certified, and will qualify for incentive programs that require SRCC certification. There is a CARB program that CA residents may want to check on.

The unit is designed for easy DIY installation -- for instance, the plumbing connections to the collector are made with two Sharkbite push in style fittings, and there are no controllers, or heat exchangers to install.
The collector contains 50 gallons of water for thermal storage that remains in the collector forever. Fresh water that is to be preheated passes through a copper pipe heat exchanger immersed in the collector water.

These units may may make sense for people who have long cooling seasons, and run AC a lot. The saving depends on the size of your AC, its efficiency, how much you run it, and the length of your cooling season. They are somewhat less effective for high SEER AC's, so make sure they will work well with your AC.

While the yearly saving in water heating costs for these units is likely to be less than a solar water heater, they are also less expensive, and potentially easier to install.

Home Power magazine, issue 104

Describes a solar water heating system that uses only one conventional water tank. The innovative heat exchanger fits through one of the water tank plumbing connections. This system sacrifices some efficiency for a more compact system with fewer components -- this might well be a good trade depending on your situation.

MHSpot.com Convert standard water heater for solar use - Save money,led lamp, don't buy that expensive replacement solar water heater tank How to convert a standard water heater tank to a solar water heater tank
I have had the fortune to deal with solar water heaters over the years. I didn't install them myself, they came with the houses that I had purchased. The first house,Product Catalog,Full Lace Wigs, the system had an 80 gallon tank with 1 single 4' x 8' roof top collector panel. It supplied almost all of my hot water. The tank of course eventually rusted out and had to be replaced. I opted to put in a purely electric water heater. At the time,Origin Oil Painting, I was single and noticed maybe $20-$30 per month increase in my electric bill.

The second house had a 120 gallon tank and twin 4' x 8' collector panels. It had a problem with the control box which I was able to repair by fixing the traces on the circuit board that had erroded away. Well, the tank on this one rusted through after 3 years. The cost of a replacement "solar" water heater tank was around $800-$1000. Now I was married and had a kid. If it went up $20-$30 before what would it go up to if I went only electric? Electricity is also more expensive now too. I decided this time to keep using solar but I didn't want to spend for the expensive solar water heater tank. Besides,LED Tube, what is different? It just holds hot water right? I ended up looking around at standard electric water heaters. I decided 80 gallons would be enough (since 120 gallons was impossible to find anyway) and looked around for one I thought I could adapt somehow to solar. I bought one and converted it. It worked out very nicely.

The conversion process
Look for a tank that has at least one extra removeable 3/4" plug on the top. Don't confuse the anode rod plugs with an extra plug. The one I got has two. I only used one though. Make sure there is no check valve or restriction on the cold water intake side. If there is, remove it. Mine had a rubber flapper. I removed it with pliers. If you don't remove it,Contact Us Add,PVC Panel, the water pump may have trouble pulling water back from the tank. Take 6' of 1/2" copper pipe, solder a copper 3/4" thread to 1/2 pipe adapter and solder the adapter so that the bottom of the pipe sticking into the tank will end up about 12" from the bottom. Screw this assembly into the tank using teflon tape on the threads. cut off the remaing 1/2" pipe sticking out - leave about 4" above the adapter. Solder a ball shutoff valve to the that. Add some small pieces of pipe and elbows. Add a anti-siphon check valve if you don't have the electric shutoff type and some more pipe to run to the hot output side of the solar panel. Add a tee to the cold water intake and adapt it down to the intake of your water pump going to the solar collector panels. The other option is to use another spare plug and do the same thing but with a 1/2" pipe that is only 6" from the bottom of the tank. This way,Solar Water Heater, you don't have to remove the check valve built into the tank - if it has one. Once everything is soldered. Apply water pressure and check for leaks. Insulate all your pipes. Don't use that cheap poly stuff,Handmade Oil Painting,built solar water heating system. BUILD A DIY, it melts within a week when exposed to the high temperatures of the solar heated water. Now when the panel is hot enough,Oil Painting Reproduction, the motor will turn on and draw water from the intake side and the hot water will go through the check valve and into the water tank.
