Have you ever noticed your boiler making a deep rumbling sound? If so, you have a problem. That sound is called “kettling,” and it indicates a serious problem with the system. If the problem is not properly repaired, it can threaten the health of not only the boiler, but the surrounding area as well. Let’s take a look at what causes boiler kettling, and what it can do to the system. (more…)

Homeowners and business owners alike know how comforting it is to walk into a building and instantly feel the heat emanating from a “radiant” heating system. While radiant heating is a common term used to describe the heat generated by a boiler, it’s actually convective and conductive heat that get the job done. Hot water moves into a radiator or baseboard heater or underneath the floorboards, in turn heating the objects and people in the room. Forced-air heating systems, which heat up the air to send it into a room through the vents, can be ineffective at heating large spaces, but a boiler is usually reliable.
That’s why it can be so surprising when your boiler suddenly stops providing heat or only provides a limited amount of heating to a room or to the entire building. Many parts can be responsible for this problem, so it’s important to trust the repair to professionals.
- Broken Circulator Pump: The circulator pump circulates hot water from the boiler to the terminal unit (radiator or baseboard) or underneath the floorboards if you have a radiant floor heating system. If the pump is broken completely or if it does not pump water quickly enough, you may only feel limited heating in one room, or you might not get any heating in any area. Usually, the pump simply needs replacement.
- Faulty Aquastat: The aquastat is a safety component that keeps the boiler from overheating. It usually has a lower limit and an upper limit, and attempts to keep the temperature between these two extremes at all times. If the temperature is too high, it shuts off the device, but if the aquastat is misprogrammed or damaged, it may believe the temperature is too high and shut down the system too soon.
- Air in the Pipes: If there is air in the pipes, it will make it difficult for heat to circulate. Furthermore, you’ll often hear a loud gurgling or banging noise in the pipes and you’ll need a technician to “bleed out” the extra air.
- Oversized/Undersized Boiler: Unfortunately, a lack of heating is sometimes attributed to a boiler that is not properly sized. You may need a replacement system in order to maintain adequate and efficient heating.

If you are someone who enjoys a good cup of tea, or live with someone who does, you have likely heard the sound of a tea kettle boiling. Coming from a tea kettle, this is a good thing; coming from your boiler, it isn’t. If you aren’t familiar with what a tea kettle sounds like when it reaches the boiling point, it’s a low rumble, and if you hear this sound coming from your boiler, it is likely that you have a kettling problem. Kettling can be fixed, but requires professional boiler repair. The experts at Celco Heating and Air Conditioning can assist you with any boiler repair issue you may have in New Haven, CT, so call us today!
What Is Kettling?
Boilers are part of a hydronic heating system, meaning they use water to heat your home. Water often contains minerals in it, especially areas that have hard water (water that hasn’t been softened with chemicals). Over time, water can leave deposits of calcium salts (lime) in your boiler’s heat exchanger. These salts are insoluble, so if they are allowed to build, they will eventually restrict the water. The term “kettling” refers to the action that happens when too many deposits are inside the heat exchanger: the water flow is restricted and as such, becomes trapped in the heat exchanger; it then becomes too hot and starts to steam, boil and expand, which is when you’ll hear the low rumble of the water kettling.
How Does Kettling Affect a Boiler?
There are a few ways kettling can affect your boiler, but one thing it does not do is cause your boiler to explode. Boilers, like all other heating systems, are equipped with multiple safety devices and mechanisms to ensure the safety of you, your home, your family and your system. Some of the problems kettling can cause are:
- Inadequate heating – kettling reduces the ability of your boiler to correctly distribute the hot water needed to heat your home.
- Replacement of heat exchanger – the pressure created by the kettling may result in the replacement of your heat exchanger.
- More stress on the system – kettling can put a great deal of stress on your entire heating system, resulting in further malfunction and possible breakdown.
