What is the most efficient way to use an immersion heater?

There is a myth that the immersion heater uses more energy to heat up from cold than it does to maintain the heat. It's always advisable to insulate the hot water tank to keep the water hot for as long as possible, but fitting a thermostat and timer alongside the immersion can help to keep energy use under control.

Therefore hot water above 120 degrees Fahrenheit can be considered hazardous.

Why is my hot water not getting hot?

Another cause of hot water not being hot enough is sediment buildup in the water heater tank. Many water heater burners are on the bottom of the tank. So this buildup of debris can make your water heater less effective at heating your water, leading to lukewarm water.

Why is my tankless water heater not heating?

Because tankless units only heat water as it's needed, running too many hot water appliances at the same time could mean the unit just can't keep up. On the other hand, your “no hot water” problem could be cause by a bigger issue such as: Plugged heat exchanger (due to hard water) A blocked vent/air intake.
