## How much does it cost to heat water with electricity?

The cost of electricity is about 14p/kWh, which means that it would cost about 45p to run a 3kW immersion heater for an hour.

## How much electricity does a hot shower use?

18.9 gallons of water used x \$0.0135 per gallon of water = 25.5 cents for the cost of water for each shower. Then, 2.5 kWh of energy required x \$0.123 / kWh = 31 cents worth of electricity for each shower. Combine those two costs and we get a total average shower cost of 56.5 cents!

## What temperature do kettles boil to?

The boiling point of water changes depending on altitude or the amount of impurities in the water, so a thermostat that stops boiling the water at exactly 100°C presents a problem. At sea level, water boils at 100°C, but for every 150-metre increase in elevation, water’s boiling point lowers by approximately 0.5°C.
