I am a newbie struggling to gain some understanding.
On the front of a Worcester Bosch Regular boiler there is a temperature control knob that as I understand it, controls the temperature of the water flowing out of the boiler. So if I set that to 50C, then the water coming out of the boiler will be at 50C and so on.
A technical spokesperson has just told me that if that water at 50C is directed to the primary coil of the domestic hot water cylinder, then it can heat the water in that cylinder to 60C or 70C or whatever temperature I set on the thermostat that is on the hot water cylinder.
Can he possibly be correct?
Surely, the 50C water coming from the boiler can only possibly heat the water in the tank to 50C no matter what the tank thermostat says. I agree that the boiler may go on trying - but surely it will never actually get to 60C and allow the thermostat to turn off. To do so, heat would have to flow up the temperature gradient which is surely against the laws of physics.
I will be very happy if you tell me I am wrong and that it can work the way he says, providing you explain how it happens, what it is that I have not understood.
Thankyou
