If it absolutely has to be done I\'d automate that. Asking a resident to
remember to press such a button does not make sense to me. People will
forget. How about this: A sensor detects that a person is near a warm
water tap or on the toilet. If the person doesn\'t quickly move around or
away this starts the recirculating pump. When the person surprisingly
walks away again or if the person turns on the warm water (flow,
pressure drop) the pump turns off again.
Yeah, that\'s a very simple trouble free approach... really??? What\'s wrong with instant on? In the households in the EU the house current provides for more power availability in a standard circuit, over 2 kW vs about 1.4 kW here. That\'s plenty for instant on.
240v 32A is 7.7kW.
I was thinking more of the 9 amp circuits that I believe are common
in the UK.
not enough though.We tend to have 15 amp 120 volts in the US, sometimes 20
amps in certain uses. 20 amps at 120 volts is practically the same as
9 amps, 240 volts and is a fair amount of water heating.
This one is 6.4kW:It may not
be enough for a shower though. I did some not so quick calculations
that show 9 amp, 240 volts will raise about a third of a gallon by 25
Â°F each minute. The average shower uses around 2 gal a minute, so
more power is needed, around 6 times as much or more like 60 amps at
