Is electric water heater better?

If you are comparing the efficiency of an electric water heater vs a gas unit, electric heaters are more efficient. Although gas hot water heaters are less expensive to run monthly due to the low cost of natural gas—a gas heater uses more energy to operate and releases waste into the environment.

Are tankless electric water heaters efficient?

Electric tankless heaters are 99 percent efficient. However, they don't qualify for rebates or an Energy Star rating, which requires a product improve energy output 14 percent over older models. The worst traditional electric heaters are 93 percent efficient.

How much more expensive is electric water heater than gas?

Does an immersion heater use a lot of electricity?

Immersion heaters use electricity to heat water, which is considerably more expensive than gas. For example, 1 kW of gas will cost you around 4p, while 1 kW of electricity will cost around 15p. That means a 6 kW immersion heater would cost 90p an hour to operate, substantially more than operating a gas combi boiler.

Can you leave an immersion heater on all the time?

Do not leave your immersion heater running all the time. No matter how well-insulated the immersion tank is, it will still lose heat and the drop in water temperature will cause the immersion heater to run repeatedly (like your kettle coming back to the boil over and over again).
