    Yesterday we ordered a machine made by LG.

    We have Solar Panel

    They tell me all there machines are capable of HOT & cold fill.

    It is a LG WM14445FS 1400RPM if you want one go into Curry's shop and pick up a leaflet there is more information on it than I could find on there web site, I then ordered it online.

    It is apparently the only thing that can be bought with Hot + cold fill.
    John Lewis no longer sell them I thought they imported units made in U.S.A

    It will be interesting to see if our electric bills drop as I am hoping.

    well, it's a bit of an old thread but all the search threw up... Does anyone know of any currently available hot & cold fill machines?

    The machine is going right next to the DHW cylinder, so pipe losses ought to be "minimal" if I could find a machine with a hot fill capability. Does anyone have any advice?

    Thanks

    -Steve

    If this is as good as it claims, it will be very good. Prioritises hot water supply too.

    For anyone wanting to do more research on this machine it is a re-badged Asko which is part of the Gorenje Group.

    I think the comparable model is the Asko W6884 Eco.

    Looks like a good machine, if expensive but cheaper than Miele and the Asko company tag line is "Built to last longer".

    I can testify to the longevity of the Asko machines. When my sister-in-law moved into sheltered housing we bought her 14-year-old Asko off her, still immaculate, and ran it for another ten years. We replaced it only because no one could get a replacement part for it after I'd dropped a full "family sized" box of washing powder onto the open detergent drawer. It would probably have still run for another ten years if I'd duct-taped over the resulting hole and used those little capsule thingies you put in with the wash instead. Wives are so fussy!

    I just love his Important disclaimer on the home page!

    It is possible to hurt your self. You can cut, burn, choke, poison, or scald yourself messing about with this. You could also fall from the roof or fall down the ladder with a cable around your neck on to a wooden stake. You could electrocute your self ( with power tools ). Blow lamps can explode and solder flux can give you dermatitis. You could get tetanus or blood poisoning from a splinter or paper cut. You could have an accident on the way to B&Q in the car. So if you follow these instructions its at your own risk. Wear goggles, steel toe cap boots, thick leather gloves, a face mask and hard hat at all times. Use an RCD and proper scaffolding . Never work outside in a thunder storm. Anything you do is your own fault, it's not my fault. I am not your mum. Good Luck see you in the next life.

    Nope, but £800 sounds like a lot. If you want a stop-gap (or possibly something for a bit longer), then I can recommend getting a second hand Bosch WFL 2450 - I've been using one for about 10 years - it's 'A' rated with a hot and cold fill, and there's one on eBay for £11 at the moment.

    There are probably older A rated or better hot+cold machines on the second hand market, but you'd have to do a bit of research I suppose...

    Shame you can't get some sort of "I'm going to want hot water next" signal out of them, then you could hook up an external diverter valve. You could probably bodge something based on timings from when the cycle starts, but it'd be a faff and need its own set of controls I dare say.

    BTW, my Bosch dishwasher manual said that it'd be happy getting preheated water up to 50 degrees, so I always feed it solar heated water, at water ever temperature the solar/woodstove thermal store is at (capped at 50 degrees by a mixer valve)...

    I got a Bosch AvantiXX, cold fill only but has lasted well. As 95% of my washing is at 40°C I really should try it with some warm water to see what happens.

    Edit:
    Thinking for about this, I measured the water usage of my machine on the ordinary 40°C wash, it used 33lt. The mean temperature was 35°C
    Worse case would be that the cold comes in at 3°C, so 1.2 kWh (about what it uses when I measured it).
    Say my water pipe from the cylinder to the machine is 10m and the pipe is 15mm, then that is 0.18 lt of hot water that is left in the pipe. 0.007 kWh for pipe losses (actually less as the pipe will cool to internal temperature).
    As my water is currently heated by E7, and I try very hard to use the washer on the night rate, not really worth me doing anything about it.

    I have an older Candy machine which has a hot and cold fill, but at present has a 'Y' connector to give mains only. This was piped up before I rerouted the DHW and before the solar thermal was installed, there was no economic benefit at the time in providing a hot connection.

    Dishwasher has already been connected to hot fill (Indesit, can accept hot supply up to 60 deg C), I will look at the washing machine soon...

    You can imagine my suprise when clearing out my Mums place went into a home, i found my mums washing machine Creda 1000 Supaspeed was hot and cold fill needless to say its plumbed in just in case its needed

    Thanks for the comments on the ISE and others, fortunately the old machine started spinning again. I cleaned the filter (nothing much there), wiggled the drum about a bit and it started working again. 12 year old Hoover hot and cold fill but only fills hot on the 90 degree wash so I have to be there to move it on to a sensible program once it's filled.

    I was quite liking the idea of a sensible hot fill with the delay timer so it could start of when it's most likely to be sunny to use the PV. Would take a lot of sun to save the £££ for a new machine though!

    I also have our dishwasher plumbed to hot. Only worth it on our water-miserly m/c because we have a very short pipe run.

    Dish washer use a higher water temperature by default I think

    That's the key point. I was intent on buying the ISE machine, but then a higher capacity (but cold fill) Siemens machine came up in the January sales for little more than a third of the price of the ISE machine. I may live to regret it but I figured that even if I have to replace it sooner the Siemens will be the cheaper option overall. Only time will tell.

    If plumbing in either a dishwasher or washing machine hot feed, to minimise wastage of hot water, you can use readily available 10mm PEX pipe - it's very flexible and easily run.

    10 metres of 10mm PEX (1.6mm wall thickness) holds 0.55 litres
    10 metres of 15mm copper (0.5mm wall thickness) holds 1.65 litres
