I can understand the reluctance of buying a Miele in the USA. From all the things I have read about Miele, customer service is not op to par with the customer service you may expect from a company that sells such expensive machines. Miele's are way cheaper here and the service is excellent. That makes a difference. I guess it makes sense to buy a machine that is widely available and that is easy to get service for. It's like buying a Speed Queen in Europe, more expensive and customer service is more difficult to get.
There are work arounds for not having a water heater in a machine, but it's just not the same. A heating element not only heats the water but also maintains it for a certain amount of time. My Siemens keeps the temperature at 140F for an hour when the Allergy cycle is used to make sure that dustmites are killed.
Not every machine here has it, but mine has a stain option that heats the water first to 105F or there about and maintaining it there for a while and then heats it up to a higher temperature when selected. In that way the enzymes can do there work best and later in the wash cycle the oxygen bleach can do it's work better when the higher temperature is achieved.
