How long does it take for 50 gallon water heater 4500 Watt to heat up?

It’s better to leave the hot water heater on all the time, rather than turning it on and off. Your immersion heater or boiler will heat up hot water which is stored in a tank. As long as the tank has a good insulating jacket, it will keep the water hot all day, without needing to be constantly reheated.
Can you have hot water and heating on at same time?
How do combi boilers work? Combi boilers provide a “combination” of instantaneous hot water and effective central heating. Therefore, the system will either transport hot water to your radiators or to your hot water tap – however, this will not be done at the same time and the hot water circuit usually takes priority.
Is it cheaper to leave your water on constant?
It is a myth that leaving your hot water on all of the time will save you money. Unless you need a constant supply of warm water, your boiler will be constantly heating when there is no real need. It is cheaper and more energy-efficient to switch your boiler on, only when you need the hot water.
