Ever since I was a kid, I’ve been a big fan of boilers for heating our house. Back when I was a little kid growing up in the far north, our parents and I lived in this old house that had a big boiler in the basement to supply warm water plus heating to the house. I can still remember being scared of the boiler when I was young, especially since it would make these scary loud gurgling sounds from time to time! Now that I’m older, I finally know that the gurgling sound was honestly the boiler start to “kettle.” Unfortunately, kettling is never a good thing for a boiler to do, as it means there’s probably a buildup of minerals or sludge inside the boiler that’s causing the water to get way too hot. Now, the boiler won’t explode, but it will become messed up after a while and it might even need to be changed. Last year, I thought our own boiler at our house was starting to kettle, too. I nearly started to cry right then out of desperation when I heard that same old gurgling sound. I knew it would be terribly overpriced to buy a brand new boiler. And thankfully for me, our heating plus A/C system repair specialist found that the actual trouble was with the thermostat for the boiler. It wasn’t really with the boiler itself. I was relieved to know that the fix was much more affordable to do. And it also could get fixed in a much shorter window of time! I would’ve hated to go over a month without some kind of heating system going in our house.
