Solar water heating system value
I have some watches for you to buy too. You are a salesman's dream.
Try reading the boxes of detergent even. The brands I have at the current hide this information completely. Cold water is always defined as over 20C for detergents. This is "warm" water from your taps...not cold. NOTE: Temperatures below 65 degrees F. will not activate laundry additives and may cause lint, residue, poor cleaning, etc. In addition, detergent manufacturers and care labels define cold water as 80-85 degrees F. http://www.midamericaparts.com/faqwashans3.htm "Cold water below 65 degrees F. is not recommended for washing" http://www.midamericaparts.com/faqwashans6.htm "As long as the water temperature does not fall below 70 degrees F (21 degrees C), you will still be getting your clothes clean." http://72.14.203.104/search?q=cache:...a&ct=clnk&cd=6 If thermal energy (water temperature) is reduced, chemical energy (laundry product) should be increased by adding more detergent. http://www.cleaning101.com/laundry/f...ct_sheet8.html "Launder using hottest water safe for fabric" http://www.fivestarlaundry.org/tips.php Tide manufacturer defines "cold water" as 65F-85F. This is not cold water from your taps. http://www.tide.com/articles/read.jhtml?articleId=3660 ....and on and on. The laundry detergent scams do not really agree with the chemical scientists. The detergent companies had to redefined "cold water" to make their claims. Advertising at work. Have a good one. "Steve Spence" wrote in message ...

I'm told my other UK folks that you do have cold water detergent. I don't know personally, I've never been to the UK. Our washing machine (Sears front loader) has a (wash/rinse) cold/cold, warm/cold, hot/hot settings. It doesn't have a onboard heater.

Many people will be using them without understanding that they can be used with cold or tepid water. 'Ozone' detergents are most often used in commercial laundries. In the machine I use the former; for hand washing (pure wool) in warm water I use soap flakes. I don't have grey whites or dull colours. Mary |

There will be close to no pressure there, and no possibility of any squirting. Okay, and if there is no check-valve in the pump or its suction, I can see that working. Maybe even a baffle just to be sure of little splash. Shut-off head of the pump will still have to be high enough to initially fill the collector, but once the return has flooded, less pressure should be needed to maintain flow. Now, just need a large enough tank to accomodate the drain-water, and you're all set. Although it would take three pipes. A foolproof way is have a tee inside the tank on the hot pipe from the panels. From this tee take a small bore pipe up to the same height as the top of the panel and back to the tank. Vented and no pump over at all. If there is a problem it goes back to the tank. Pipe is cheap. Why go all the way up to the panel height? If you make sure the hole is always above the water level in the tank, and put a small enough orifice/restriction in the hole, the flow of water out the hole will be minimal. With the pump off, the difference between where the hole is and the water level in the tank will start the reverse syphon process. As water syphons backwards through the collector and pump, the return line will be more and more air (less and less water) so the dP for the syphon grows and grows. Soon the whole pipe and collector will be drained. Things that can go wrong: 1) If there are any low spots that don't slope back to the tank, they may hold water that can then freeze. 2) Some fool puts a check valve in the line. 3) If the orifice/restriction/hole gets clogged with scale/crud/biofouling, then the system may not drain. The first two are avoided by careful installation. The last, increase the height above the water line for the hole to provide a stronger dP for clearing the crud. Heck, maybe rig a circuit that if the pump is running but no water out the hole after 60 seconds, sound an alarm. Scale could be prevented with a simple mechanical reamer every 3 months or so. But running a pipe all the way up to panel and pack down creates a 'loop-seal' that will *prevent* drain down, exactly the wrong thing. Now you have to 'upside-down U' sections of piping to break the syphon seal on both to prevent freezing. daestrom |

wrote in message ... Doctor Drivel wrote: wrote in message ... Once the panel circuit fills with water, the pump is only pumping against the running friction, and not the head. It is pumping against the head (pressure) always... Wrong. Not entirely. To prevent forming steam in the top most portion, the pressure there must be kept above the saturation pressure for the temperature. So if the collector outlet temperature is 180F, the pressure must be kept above 7.57 psia. With the return line open to atmosphere (14.7 psia), then the vertical fall from the collector to tank is limited to somewhere in the range of 16 ft. If you arrange so the major friction loss is on the return line, say a throttle valve right before the tank return, then the pressure drop across it will add to the pressure 'seen' at the panel (i.e. the backpressure raises the pressure in the panel). This would support more vertical height panels. The *worst* thing would be if the throttle valve/restriction were on the riser side. daestrom |

But running a pipe all the way up to panel and pack down creates a 'loop-seal' that will *prevent* drain down, exactly the wrong thing. As the end of the pipe is open to atmosphere in the tank at "all times", it will not cause a vacuum and lock in the water. When the pump is on, it will pump some way up the pipe, how much depends on pump friction, etc. Once the pump stops, the water in the pipe will drop back and as it is a open vented pipe, the water will just fall back. The last thing you want is water dropping from a small hole inthe wtaer in the tank, as this aerates the water. Not what you want. |

During the CA energy crisis (I would hardly call it a 'collapse' since the only time people lost power was when it was deliberately *turned off*), the messages went out for people to do a *lot* of things differently to conserve energy. Not just washing machines. And to shift there energy usage to off-peak hours. But not just washing clothes. Running A/C, taking showers, cooking dinner, any thing to reduce peak demand. daestrom |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Doctor Drivel" saying something like: In yea olden dayes the dishwasher was a large tray of water with powder like sand. It sand blasted the dishes clean, hence why you could not put patterned plates in the things. That was a concrete mixer. Understandable mistake, I suppose. -- Dave |

At least some of the big name manufacturers' top brands do indeed incorporate heating elements. The Maytag Neptune series is the only one of these with which I've had first-hand design experience. It should be noted, however, that the heater is used under computer control in such a way as to reduce the overall water/energy budget of the machines' wash cycles. I was also told that they'd experimented with incorporation of an ozone generator into some test machines with the aim of reducing detergent and bleach use; but that the idea was dropped because the ozone unacceptably shortened the life of some common synthetic fabrics. I had an opportunity to examine a Japanese machine that used a flood of tiny air bubbles to completely replace detergent - and I understand that the technology is considered "promising". The primary factors involved are 'wetness' and the mechanical action of flexing fabric/causing water to move between the fibers. Detergent acts to make water "wetter". Warming the water improves its ability to disolve some types of soil. If the water were cooler, the machine would need to run longer to produce the same level of cleaning. The real deal is to make the machine smart enough to figure out where the optimums are each individual load - because the parameters change dramatically from load to load. They've been working on it; and the development has been (and will continue to be) an iterative process. -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto |

Well, it's the same to the extent that the water temperature is raised. :-) If the water in the pipe between the DHW is cold, then it turns out to be uneconomical to soak the load with cold water, run cold water into the drain, and then attempt to achieve a minimum wash temperature by adding enough hot water to warm the cold water in the fabric. Some areas of the US have a serious need to minimize water use and one of the major design goals is to reduce the demand. If you have a chance, check out the amount of water used in the top-loading Maytag Neptune - you'll be amazed. In that machine there is a tiny sump between the tub and the drain; and the electrical heating (of only a tiny amount of water) is done there. The amount of water actually heated in the washer is unlikely to be anywhere near the amount of DHW drawn from the tank and left to cool in the pipe - or the amount of cold water wasted while the DHW traveled from the tank to the machine. -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto |

On 11 Mar 2006 08:46:25 -0800, wrote: You wont get 75% efficiency for hot water, but can for hot air. It looked like this was possible from the SAP pdf, what makes you think it will be worse on water and better on air? Air target temp is low, the output air need only be mildly warm, low temp panel operation equals good efficiency. OK again, in fact the efficiency of either given the same delta T is about the same, if you mean T between panel output and ambient, yes, if you mean between panel input and output, no. With hot water the target temp is close to the stagnation temp of the panel, so once the water is halfway hot the panel efficiency is way down. Even this is somewhat dependant on what algorithm you choose to make use of the heated water, I dont honestly see how, its just the physics of solar panels. With T_out = ambient, efficiency is at its maximum, somewhere in the region of 90%. When T_out = T_stagnation, efficiency = 0%, and you can draw a straight line between those 2 points. in my case I will almost certainly feature a thermal store, because this fits in with wood burning, it certainly adds a lot of cost but would enable harvesting of sunshine at a low temperature. Curious how you plan to use the same panels for both water and air It's still a pipe dream atm, my heating is largely provided by wood that just costs me a bit of effort to collect, so investment in solar is not a good one for me. If I were faced with re roofing (1862 built property seems to have been re roofed once after fire damage) then although it is SW facing a warm roof with triplewall polycarbonate weather surface looks feasible. To implement this my thoughts are that the solar DHW could be supplied by a small portion of the roof I think that would be the simplest answer. and aim for enough collector area to fill a thermal store and supply all summer and some spring and autumn needs. You realise you'll need 2 types of collector, flat plates will get your water warm but not fully hot. To heat the top hottest section of the store, vac tubes or concentrating collectors would be a lot more use for that bit. I wonder if I would get away with circulating the water through just the front face of the two channels, water is pretty opaque to IR. sure, but it wouldnt get hot If so then the air doesn't need to share the same passages and can have a manifold to the rear channel over the whole length of the roof blowing down to the bottom and into the lower part of the building, ideally into the floor slab. Well I'd love to see you make a whole bunch of such manifolds that will survive 20 years of use. I cant see how it could be possible. If you fail, it'll be you on the roof fixing it. So if you do try I'd fit a row of isolating valves. I am in two minds whether to nick it off the roof before it is sold as the estate agent says it does not increase the value of the house. AJH Sounds logical, if you have legal title to them. If you dont use them they sell for a good price. Look at navitron's prices, £220 for a 10 tube panel. NT |

"Guy King" wrote in message ... The message .com from contains these words: If it is so good, I want some and will meddle with the washing machine to get it to work cold only. Or just set it to low temperature wash. Disconnecting the heater makes it sit there forever waiting for the temp to be reached. Instead wire over one of the temp stats. I don't like washing machines that have fixed temperatures for given wash programmes - I prefer to be able to choose my own. If I want to run a long wash at 30°C then that's what I want to do - not have the machine force me to do it at 80°C instead. Some machines have a seperate thermostat dial - which makes a lot of sense. What are you doing trying to operate a washing machine anyway? That's women's work. Get back to the pub! Mary |

This is the answer I got this morning from Candy UK when I asked why they don't sell hot/cold fill machines. Good morning due to the cold water in take the water level intake have been reduced washing machines only start to heat water at around 60degrees and above so hot water intake is not needed hence why it it more energy efficient Make of that what you will. -- Skipweasel Pay no attention to the man behind the curtain. |

As most DHW is 45-55C this is tripe. What they are hiding is that they want to put less in the thing. |

Most DHW has cooled down to ambient temperature in the 'dead leg' from the store to the washing machine inlet valve. What is the _measured_ temperature of the inlet water at time A - start of fill; B - end of fill? -- Brian |

As a result hot water will arrive at the machine almost instantly. Do you not think that other considerations should be considered far more important than this in sensible design? That rather depends what the aim of the design is. In my view reducing running costs and so reducing greenhouse gas emissions is at least as important as anything else. That does not mean it is the only consideration. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |

wrote in message ups.com... [...] Have you provided a figure to rebut mine with? Yes. Did I miss it? What is your figure for the annual saving of a typical commercial DSHW system, and how do you arrive at that figure? OK. Since I caused the confusion, let me explain why I thought that the cost (or savings; sorry for the misunderstanding) was extremely low : Here is a 'saving' calculator for DHW : http://www.infinitepower.org/calc_waterheating.htm I have a 1-family home, using a 50 gallon tank with about 65% overall efficiency, using about 60 gallons HW per day. Gas-powered. Northern California natural gas price (retail) is around $1.50 / therm. So, I see DHW cost of about $350/year. That seems right extrapolating my summer gas bills (when I use gas only for HW). Now, expected savings using solar DHW should be beteen 50% and 80% of DHW usage (seen this at various web-sites). So I should save between $175 to $280/year. And note that I an on the low-end of the consumption scale, using nat gas for DHW in a small household, using front-loader European washer, and water-saving shower heads and such. Most people use a lot more than me, and many use electric DHW heaters, which essentially double the cost. So, once again : how did you get to savings of just £20 / year ? Rob |
