Boiler - burner - hex cleaning.

[Old Account]

you want it to be big ie 60-25-30 etc plate is good

60-55 plate bad / needs cleaning

Usually the flow temp. Is set to 55-60c and return is mostly 15-20k difference. If I had a boiler 65 flow temp and return is 58c that means I could have a bad steel plate which needs cleaning?
