Q: Iwhen we check water heat in the bucket with current connection. A: please dont check the temperature when the rod is immersed and switched on. Q: What time its need? So the two bits of information you will need to help calculate this are the size of the tank measured in litres, and the required temperature rise.
The required temperature rise measured in centigrade is calculated by taking the starting temp of your cold water from the hot water temperature required. For example, if your water is 10 0 C and you want to heat it to 60 0 C, then the temperature rise would be 50 0 C. The following formula can then be used to calculate the power in kW needed to heat a specific volume of water by a given temperature in 1 hour.
So if the tank is litres and you want to take the water up to 65 0 C from 10 0 C, then it would simply be:. This means that you would need 8kW of electricity to heat this volume of water in 1 hour. If you wanted to heat it in 30 mins you would need 16kW of power, and so forth. If you take the example of required temperature rise above and you have a 3kW immersion heater it would take about 2hrs 30 to heat the water 3kW each hour, so in two and a half hours that would give 7.
Normally though, the immersion will turn on and off via the thermostat so the amount of time they are on fluctuates, depending on the existing temperature of the water in the hot water tank.
Hopefully the above has been useful and you can apply it to your home! Please remember that hot water should be heated to at least 60 0 C in order to kill legionella bacteria! Save my name, email, and website in this browser for the next time I comment.
We have a house heated only by electric not storage heaters and a l unvented water tank heated by immersion heaters. If I want to use the showers in the morning and again in evening is it best to heat up the whole tank and hope it stays hot long enough for the afternoon? I can be away for a week or two at a time so it is not used constantly but i am confused by all the different answers as to which is the most economical way to use it. Solar is not an option for our house and nor is there outside space for a heat pump.
Hi we had a new heating system fitted and the company who fitted it left the emersion on 24 hours 7days a week for 6 months how can we calculate how much this has cost us so we can claim it back many thanks. Hi Andy, on the face of it this is really simple — i.
This means when the water in the tank reaches the predetermined level then the immersion unit turns off. Imagine the immersion as a kettle — when the water boil, the kettle element turns off.
The same thing happens here, so the actual figure is impossible to calculate so apologies! By turning it off which i did after i came across your article, you could just monitor your electricity usage and compare, and thats how much you wasted. We simply halfed our electricity cost switching it off. If someone is going to make a claim lets try to get a more realistic figure which should be achievable by the meter reading now the immersion is off.
Hi Ron, so the cost of gas is approximately 3 pence per unit while a unit of electricity is approximately 12 pence. Therefore to produce one unit of useful heat you are looking at a cost of 3. I have mine on 24 seven, 7 days a week. Haha — sadly not a simple question. I would suggest though to keep things simple you turn it on and off as needed since heat loss always occurs. My machines are plumbed this way.
