Boiler Cleaning/ uneven room temperatures
Hello, I am new to this site. I have two questions, both pertaining to my gas boiler which was installed in October 2005. Last year we asked our plumber to come down and clean the boiler and he told us that it didn't have to be cleaned for five to seven years... is this true or should I have a service tech come down before winter sets in and have it cleaned?
Also, since it was installed we have had uneven heat temperatures in our rooms. One room is very comfortable and the rest of the rooms are much colder. If we turn up the heat to warm up the "cold" rooms, the other room is very warm.
NOTE:
We have two zones. One zone for upstairs, where all the rooms heat evenly. It's the downstairs zone where we are experiencing the uneven temperatures.
Thanks...
