Hi
After using hot water a few times today (taps and shower) while the central heating was off, we noticed the pressure on the boiler rising. it was at 1.2 initially. When hot water turned on, burner fired up and pressure dropped (as it normally does to 1.1 ish). On turning hot water off, needle went back up to 1.2 ish and then continued to rise to 1.3.
the 22mm heating pipe next to the 15mm hot water supply pipe was slightly warm at the top near where it is attached to the boiler. The rest of the pipe was cool. Is it normal for the heating pipe to warm up slightly at the top. is this what's causing the pressure rise? do i have a problem?
Thanks in advance for any suggestions.
