Dual element electric[edit]

I added this section with details on the flow and switching. I seem to remember that the thermostats have an interlock so both elements can't be on at the same time. This is because they are each max wattage for the breaker and wiring. I would like to add this as well if I could find an RS as well as an RS for my {cn} statements in the same section.--Canoe1967 (talk) 18:53, 7 July 2012 (UTC)[reply]

The Dual element electric section contains a single reference to a Popular Mechanics article. Most of the section is consistent with the reference and the referenced article is, in my assessment, basically accurate though quite general. That said, the particular statements about reversing top and bottom temperature sensors is not addressed in the reference and I know of no good reference. (I do know of many websites that have articles on dual element heaters and they are mostly written by people who are not knowledgeable and often wrong.)

Two thoughts here: 1. I think the present discussion is unclear. If we are presenting a description of a generic residential hot water heating system, then the water exits from the top and enters from the bottom. The article refers to a system with "warm feed from the top, hot from the center." I imagine that there are many complex systems, but if one is going to discuss one system that is not the most common and generic, then some mention of the existence of several types is needed? 2. I learned from this article that dual element water heaters do not normally employ both elements at the same time. Thanks. Apparently, the correct setting of thermostats are such that the lower thermostat is never higher, but can be lower, than the upper thermostat. Amid many inaccurate web sites, if found one that makes much of this clear. http://www.whirlpoolwaterheaters.com/learn-more/electric-water-heaters/how-electric-water-heaters-work/standard-electric-operation/ Feel free to respond to my observations or not and if no one changes this or objects to this, I may edit the article in the near future. Also, my information is US specific so I would be happy to be pointed to a more international information source. Mike (talk) 18:29, 23 August 2016 (UTC)[reply]

Temperature.[edit]

Article states: "Water heaters for washing, bathing, or laundry have thermostat controls to regulate the temperature, in the range of 40 to 60 °C (104 to 140 °F)" This seems to be referring to instaneous water heaters, not hot water storage tanks. Hot water storage tanks must be maintained above 60 °C to prevent the danger of Legionnaires’ disease. http://www.couriermail.com.au/questnews/southwest/hot-water-system-to-blame-after-camira-woman-contracts-legionnaires-disease/news-story/46cdbbb86ca4b12c656e9f6a382475f2 https://www.qld.gov.au/health/conditions/all/prevention/legionnaires-prevention/index.html Swampy 2001:8003:200B:9500:69C2:8496:2681:7F0E (talk) 16:49, 13 June 2017 (UTC)[reply]

It looks like you get to choose between dying of agonizing pneumonia or dying of agonizing third degree burns: [[1]]. From 2005, and as far as I know Canadian building codes haven't been changed to mandate mixing valves at the tap so you can set the water heater to 60 C. --Wtshymanski (talk) 18:58, 13 June 2017 (UTC)[reply]

Difference between this article and Storage water heater[edit]

Hi there, what's the difference between this article and Storage water heater? It seems to have the same subject. Maqdisi (talk) 16:43, 5 March 2023 (UTC)[reply]
