Woke up in a cold house. Hot water is OK but no hot water going to the rads. Water levels OK, no warning neons. Neon for CH is not lit at all. All the red temp neons are lit. I can't hear a pump going but I am not sure that I ever did when it was working.
Sure it is something simple but not sure what to check next. What should I look at next?
many thanks...
