I added a couple of rads to our heating system in jan,ran 15mm off 22mm flow and returns to feed 2 small rads one in wc and one in bathroom.
There has been a bit more system noise than before since they were added.Over the last couple of weeks the boiler has on occassion been giving out a little boom.
On sat I noticed the pressure was up to 3.5 bar normal cold pressure is 1-1.5
I bled all the rads and set the cold pressure to 1bar,fired up the heating and after about 20mins the pressure was up to just over 2 and the left side of the casing on the boiler was very hot.
Have turned the c/h off
Any ideas what it might be,could it be to do with me adding the rads?
They both have trvs on.
The boiler is an ideal isar m30100
TIA
