Electric hot water systems are generally cheaper to install than a gas hot water system, however in the long run they are usually more expensive to run as they use a lot of power to heat the water and the higher cost of electricity.

Alternatively, an instant electric hot water system can be very efficient as it only heats the water as you need it.
