 Good Question, Maytag played all kinds of games trying to have lower operating costs, If you look at cycle charts for MT DWs in the 1980s [ all the same year ] they had at least three different major cycle variations for a normal wash cycle regarding number of water changes, cycle times and heater use and any possible temperature holds.
It was like you were looking at charts for three different brands, better performance was differently a Step-Up feature on MT DWs.

The oldest MT DWs with the figure 8 filter and heating element ran the heater all through the 18 minute wash and had complaints about severe etching of glasses, especially in areas with soft water. | ||

I thought energy was cheap back then?
Its interesting though- not sure why- but I remember many years ago always seeing old Maytag DWs in homes with oil heat. Basically a boiler that was always set 180*, often there was a tempering valve when feeding over to shower fixtures. The area had a Maytag dealer too, so I guess it just worked out in that market niche. And yahhh I noticed that too, main wash increases on high end models. I think its cruel to do that and helped tarnish the Maytag reputation. More people buy BOL and MOL, especially back in the day when DW were new and high priced so having a short main-wash without heat just forced others to buy from others like Whirlpool who did not go to such great lengths to force TOL. | ||

Try not thinking, just whoring after Department of Energy stars. | ||

Even if the boiler heated the domestic hot water with a coil that used boiler water to heat the domestic hot water so that the two never touched? ? | ||

Around here many did not have a tempering valves or only supplying faucets. Thermostat regulated to about 180*. Yes the water was that hot.
@Tomturbomatic: Ideally or with homes built today you would have a separate storage tank where the boiler water is pumped through a coil inside the tank. A thermostat is present which triggers the pump and burner cutting off when the right temp is reached. For what ever reason decades past it was very popular in my area to just take a Weil Mclain and use the boiler for both domestic hot water and hot water basebaord always keeping the jacket at 180* year round. I have no idea if this is true or not as I am not an HVAC tech or expert in HVAC but was told the reason this was done was because if the boiler is allowed to cool down frequently the seals could start to leak over time. | ||

Replay # 17 " Around here there was no tempering valve for domestic hot water, water was about boiler temperature of 180F "
I have never seen such a system in this part of the country and have been told by plumbers that it would never have legal in the last 70 +years, what part of the country are you talking about and in what time period was this system installed ?

Knowledge of codes varied widely back in the day as well as the enforcement of them.
Good example are 3 wire sub-panels which were never legal in the same structure but you can find countless apartments and condos built here and there up until the 90s with 3 wire feeds as well as 10-2 and 6-2 bare ground to the dryer and stove. (code requires the neutral to be insulated when using NM) Disposal or lighting tapped off the SABC, #14 to dinning room receptacles, GFCIs not installed despite being required at the time for that area, ect, ect. Most of the homes are from the late 40s-50s. Some have tampering some don't, some have it just for the fixtures. | ||
