and a normal boiler style water heater.Which uses more electric bath heater or shower, 20mins?
If the shower is the normal electric one that heats the water from cold then these are normally 6KW. A normal immersion heater is 3 KW. Therefore the shower will consume double the electricity.Which uses more electric bath heater or shower, 20mins?
i can't stand baths bathing in your own dirt is not nice and they take ages to fill up you can't wash your hair propley you get my drift where as showers its clean water going onto you and easy to wash hair and no waiting around for anything to fill up just push the button and way hey
A 20 minute shower is a really long one. Its all about Kilowatts though. a typical shower like yours is 9.5 KW, so that is about 3 KWH for a 20 minute shower. If the water heater is less than 9.5 KW then it wont use as much.
The water heater would use more electricity if you were heating it up from cold, especially if you needed enough water to fill a bath.
Bit of a trick question, not even my wife could possibly spend twenty minutes in the shower!
water heater, it comsumed more electricity.
