Hi, I have a honeywell 3 port vavle that is causing me so many problems! It has already been changed once and still problems persist.
Both the heating and hot water are on, on the programmer and both stats are calling for heat. The pipe going into the bottom of the 3 port is red hot, as is the one going to the rads. (rad all getting nice and hot). But the pipe going to the hot water cylinder is only luke warm and the pipe coming out the bottom of the cylinder is cold. If I turn the heating off, then the water flows around the coil to heat hot water.
So my problem is when both are on, the heating is taking priority. Which often means I have no hot water, as It only heats up if the heating gets up to temp.
Another problem - maybe related, is that when the house is up to temp the heating goes off. But then if the house cools and the heating should come back on, it doesnt. You have to go upstairs and manually push the 3 port open. It then remains on heating up house again.
Anyone any ideas?
