Answer(s):
Professional estimator
From the calculations below, you can see that it is significantly cheaper to use a gas shower.
Gas vs Electric Shower
Electric
Assume a 9kW electric shower and 10-minute shower.
Cost = 9kW * 0.167 hours * £0.34/kWh = 51p
Gas (powered, i.e. gas boiler heating hot water cylinder)
Assume 9kW again and 10-minute shower.
Cost = 9kW * 0.167 hours * £0.10/kWh = 15p
*The above costs exclude the cost of water, which will be the same in both cases. I’ve assumed the same flow rates, i.e. not power showers.
