Washing m/c and cold fill ... A++
Decided to replace ageing Hotpoint washing m/c
This used hot & cold connections ... Surprised to find that replacement (WMUD962G) only has cold fill. Yet it has A++ Energy rating ....... surely heating water by electricity is less economical than using that already heated and in your HW tank. |

Maybe it's something to do with many houses now having combi boilers and no hot water tank, that means it is easier for the WM to sort it out itself. |

It is probably that in many locations the hot water would not have run through by the time the machine is full. This is possibly made more likely with reduced water consumption.

I agree but you do not find any with both any more. I suspect its far too
complicated to monitor both and do cool washes so they cop out and start with just cold. Brian -- From the Sofa of Brian Gaff Reply address is active "Rick Hughes" wrote in message ...

Surprised to find that replacement (WMUD962G) only has cold fill. Reputedly because the time taken to heat the water is part of the soak time the washing cycle needs. There's also an issue with dumping very hot water into delicates and into powders/tablets, etc. designed for a low termperature wash. Our machine does have a hot inlet but it only uses it when you select a "boil wash" (80C IIRC) all other times it draws from the cold only. Gordon |

Brian Some Meile dishwashers accept hot fill, but cold is the norm. Also, washing machines, detergents work better with some types of staining if the water is cold initially - eg protein based (egg, blood etc) as hot water can cook and set the stain. -- Tim Watts Personal Blog: http://squiddy.blog.dionic.net/ http://www.sensorly.com/ Crowd mapping of 2G/3G/4G mobile signal coverage |

Tim ISE makes one that has hot fill http://www.iseappliances.co.uk/index...88eco-overview towards the bottom of the page. It mentions the distance to the source of hot water; also says that the pipe should be lagged - only relevant if there's a branch near the machine or if hot water is taken later in the process (the water is probably taken incrementally anyway). -- Peter.

There are a couple of drivers for this now common configuration. The first is the lower water usage, that quite often means a hot fill machine will simply end up drawing all the cold water dead leg out of the pipe and then stopping before it gets the benefit of the hot - thus wasting the hot water. The other is the increased use of low temperature bio detergents that need to have adequate contact time at a cool temperature before being heated during the cycle to be at their most effective. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

And even machines which *do* have hot and cold feeds tend to use cold, and heat it internally, for all but the hottest cycles - otherwise the incoming water may be *too* hot for delicate fabrics, etc. -- Cheers, Roger ____________ Please reply to Newsgroup.

Chris That's very probably it. We normally usually use powder or liquid in a ball inside the machine, but on the odd occassions that we use powder or tablets in the soap drawer, we are left with sludge in the drawer, unless we run the hot tap to get hot water down to the kitchen before starting. That sludge, of course, ends up in the next rinse fill. SteveW |

I went out of my way to get a H&C machine, but it uses such a tiny amount of water compared to its predecessors that unless I draw off the dead leg of cold water via the hot tap beforehand, it never gets any hot from the tank. And even if I do that, it fills from mains cold and hot tank concurrently, so guess which it gets most volume of? In short, I think that better energy/water efficient machines, combined with 30 degree detergents have made hot fill a bit redundant ... |

By the time the cold water in the pipework is drained into the machine, very little hot water gets there anyway. In any event a cleaner wash results from starting off cold, hot water seals many stains in. Also the machine is cheaper to make. So H+C fill has no advantages at all. |

There was an article in _Which?_ in the past few months about 60° washes. Most washing machines don't actually reach 60°; only one holds it there for long; but some experts think that modern detergents & washing machines can remove bedbugs & germs effectively (down the drain) without killing them. What's not killed in the cold wash in the machine probably will be killed with a good drying on a washing line. Absolutely. I keep our toothbrushes in the bathroom window for the same reason (sunlight can sanitize things). |

Machines now only heat exactly as much water as needed. This greatly reduces wasted energy for most people. I have to run almost 1 L of water out of the kitchen tap to get the hot stuff, so based on the pipe runs, I'd expect the first 1.5 L of "hot water" into the washing machine to be cold. But I was surprised to see in the manual that the washing programmes use 52 to 65 litres of water; I don't know how, however, how that's split between the wash & the rinses. There's also the factor that modern detergents work better when started off cold and the heated to the required temperature. That's what I've heard. |

I have Economy 7 and the timer is always set for night time use. But you're right, I would have thought it would be cheaper to heat the water by gas. Maybe it's something to do with many houses now having combi boilers and no hot water tank, that means it is easier for the WM to sort it out itself. Why? A combi boiler will produce cheap hot water when the machine demands it. Doesn't affect me as I use cold wash. -- "His idea of safe sex is an `X' spray-painted on the rump of animals that are known to kick." |

Reputedly because the time taken to heat the water is part of the soak time the washing cycle needs. Gas kWh = 6p Electricity kWh = 14p. Heating water with electricity = stupid. -- If you jog in a jogging suit, lounge in lounging pajamas, and smoke in a smoking jacket, why would anyone want to wear a windbreaker? |

I went out of my way to get a H&C machine, but it uses such a tiny amount of water compared to its predecessors that unless I draw off the dead leg of cold water via the hot tap beforehand, it never gets any hot from the tank. And even if I do that, it fills from mains cold and hot tank concurrently, so guess which it gets most volume of? In short, I think that better energy/water efficient machines, combined with 30 degree detergents have made hot fill a bit redundant ... I used to have an H/C one but it only used the hot it you turned the dial above 40C for some reason. -- Did you know that dolphins are so intelligent that within only a few weeks of captivity, they can train humans to stand at the edge of the pool and throw them fish? |

With two caveats - one the machine will need the occasional hot wash to not fill up with detergent residue slime. Doesn't happen here. Also tests have shown that low temperature washes are not as effective at killing bacteria - so take care with what you wash with and after bacteria heavy items. Bacteria is on dishes, not clothes. -- Anybody who claims that marriage is a fifty-fifty proposition doesn't know a damned thing about women or fractions. |

By the time the cold water in the pipework is drained into the machine, very little hot water gets there anyway. In any event a cleaner wash results from starting off cold, hot water seals many stains in. Also the machine is cheaper to make. So H+C fill has no advantages at all. Funny, if I turn on the hot tap in my sink, I feel warm water in a few seconds, and the tank is in the next room. -- The wife had a birthday and her husband wanted to know what she desired.
