We got an open fireplace with a back Boiler it also feeds the radiators with a pump, the water goes via the back boiler through a coil under a hot water cylinder heating the hot water. My question is, if the hot water would be connected to a pump EG pumping the water passed the back boiler through the coil would it increase the efficiency of heating the hot water on the cylinder in the summer when not using the heating?
My thinking is that and the oil boiler attached to the system when switched on uses a pump to move the water around from the boiler in the garage to the coil in the cylinder to heat it, in case of open fire the water comes first from the back boiler into the coil via pipes it then can heat the water in the cylinder, so I was thinking getting water quicker to the cylinder would speed it up getting water in cylinder hot.
