What is the difference between a bath and power shower?
A medium sized bath uses 150L of water, a power shower for 10 minutes uses about 150L of water, so a bath and a power shower could cost about the same, if the water used in both is heated in the same way. A low flow shower uses about 50L of water and in this scenario, would cost about a third the price of a power shower.
How much electricity does a bathroom fan use?
How Much Electricity Does a Bathroom Fan Use?
