What is the most efficient way to heat domestic hot water?
Some of the most efficient water heaters find creative sources of heat— such as other heating equipment, outside air, or the sun — to provide hot water with less fuel. These include heat pump water heaters, indirect water heaters, integrated space/water heaters, and solar water heaters.
Why does my hot water keep going cold?

What temperature should the hot water be on a combi boiler?
For combi boilers, the recommended output temperature for the radiators is 75 °C and for the water it’s 60 °C. You shouldn’t need to adjust these output temperatures as you may alter the boiler’s efficiency.
Is it cheaper to have heating on constant?
According to experts at the Energy Saving Trust, the idea it’s cheaper to leave the heating on low all day is a myth. They’re clear that having the heating on only when you need it is, in the long run, the best way to save energy, and therefore money.
Does turning off hot water heater save money?
