COLD WASH

Re: COLD WASH

Hi John

A good read here on cold filling from this list which covers the majority of scenarios you are likely to come acoss on a day to day basis.

Just a quick question what is the advantage of a cold fill washing machine compared to a hot fill?

Uses on average only 50 litre a wash and about 8 pence of electricity per cycle. Old machines like the old Hotpoint 95 series and the Hoover logics used about 120 litres and goodness knows how much electricity. So if customer is on a water meter it will save them loads of dosh and the same on the electricity side as well.

I think that the article was written years ago and indeed does not cover the information you seek John. Washing machine operating system design has changed quite significantly these days and it could do with up-dating.

The major factor toward cold fill only is that each and every modern machine only needs just a few litres of water coupled with the lengthened wash action and drum paddles that shower the clothes constantly. Cold water ensures the incoming temperature being well below the pre-set wash temperatures required and better temperature control coupled with the necessary wash times infinitely more controllable electronically. The older hot & cold machines filled with more than twice the amount of water than the modern machines. As a result the wash times were much shorter in achieving the same result.

On the environmental aspect and because the modern machines take in less water and thus require much less time to heat that small amount of water, they have suddenly become ‘eco-friendly’ and acceptable in the market place. Now to quell the doubters over the omission of a hot fill on modern machines they came up with this excuse. That by using hot water from a domestic hot water heating system the ‘displacement’ would be significant and more energy used in order to replace it. That fact is hogwash but it seems to appease many. What is a fact is that a hot valve has been designed out, totally unnecessary and has greatly reduced manufacturing costs by it’s omission. Much like the redundant nuts, bolts and screws are in today’s modern machine design. Far cheaper to put in plastic hooks and clips and weld drums together than the prohibitive cost of the old nut and bolt eh? Stands to reason. 😉

Re: COLD WASH

I suppose in my case I save money by using a cold fill machine. My combi boiler is a long way from the washer so you have to run about a gallon of water before it starts running hot. That first gallon just sits in the pipes when the machine stops filling but all of that water has been instantly heated by the boiler…..
