A question of efficiency?
-
If you reduice the flow, it takes the tub longer to fill up, so the water already in the tub will have longer to cool before the tub reaches the desired level. I think taking a shower would be better than either of your two options. I take what's referred to as a "Navy shower": 0) wet down, turn off water (I have a showerhead with a valve that controls the flow of water. 1) lather up, turn on water to rinse off Done. I bet I use a little less than a gallon of water to shower. We have an electric water heater, and I don't turn the water up much past room temperature.

I've got four daughters who absolutely must have, without fail, at least 3 baths a week. Bloody teenagers! They can't shower (their words, not mine) because they can't get their hair wet unless they're washing it which they do separately. :doh: :confused:

man up and use cold water.

So there I was, sitting in the bath contemplating the meaning of life when it occurred to me which is the more efficient? Let me elaborate. In our house, the hot water needs are served by an 'on demand' gas boiler. This boiler has a dial which allows setting the hot water temperature. This temperature adjustment is achieved by altering the volume of gas to the burners. The same temperature adjustment can be achieved by altering the flow of water through the taps. I.e, turn the tap down, the water gets hotter because of the water flow reduction. So, here comes the question: which is more economical and energy efficient to fill a bath? A. Turn the temperature up on the boiler (thus increasing the volume of gas burnt) but more water enters the bath so the boiler doesn't need to be on as long. B. Reduce the water temperature on the boiler (thus reducing the gas flow) and then reduce the flow of water at the tap so the water passes the burner slower and thus heats up more but takes longer to fill the bath and hence the burner is on longer albeit not burning as much gas per given moment in time. C. They are the same. D. Who gives a s**t. I'd be interested to hear any thoughts.

I must thank you for making me feel less alone in the world of people wondering about such things. I extended the scope to the heating of my flat (better constant heating to a target temperature all day, or better heating off but for two hours in the day with then full heating ?), which is more or less the same.

Bah! - You should put a small LHC under the bath tube... - Or using used "fried" oil as gasoline in order to be greener (even you go out from the bath you'll smell funny). - Of course the best option here would be to use the DutchTub[^]. Green people to me... bah! :rolleyes:

Sounds very similar to the question of when you should add milk to your tea in order to ensure a hot cup of tea. See Newton's 5/4 Power Cooling Law.

That is the exact same excuse my ex-wife used as to why she didn't shower every day. I told her Bullsh!t! Then I talk to beuticians and they said you can get your hair wet (don't they walk in the rain or get in water fights?) even if you don't wash it! It's just an excuse to not shower every day. My daughter follows her mother in this nonsense. I guess at least they take a bath when they don't shower which is NOT what my ex did!

Not in England it isn't ;P It's usually freezing, even in summer. Though just to prove me wrong, we've just had the hottest April on record.

I have a similar problem with brewing tea, only to have it chilled to a very cold temperature so I can enjoy it. I'll post the problem shortly.

Skinny dip at the nearest lake or, preferably, hot spring (true story: a guy actually got full on naked and used body wash to clean off in front of me and a friend at a hot spring).
