6 Common Boiler Myths

Boiler myths often leave homeowners needing clarification about how these heating systems work. Whether considering a new boiler installation or just trying to get the most out of your existing one, it’s essential to separate fact from fiction.

1. Boilers Only Need Maintenance When They Break Down

A common misconception about boilers is that they only need attention when something goes wrong. However, regular maintenance is essential for ensuring your boiler operates efficiently and lasts as long as possible. Scheduling professional tune-ups allows technicians to identify potential issues before they become major problems, preventing costly repairs later. In addition to reducing the risk of breakdowns, regular boiler maintenance helps improve energy efficiency, ultimately lowering your heating bills.

2. A Bigger Boiler Is Always Better

It’s a common myth that the larger the boiler, the better it will heat your home. In reality, a boiler that’s too large is less efficient at heating. When a boiler is too large for a house, it can quickly reach its temperature setpoint and then shut off. This process, known as short cycling, wastes energy because the boiler has to work harder to reheat the system each time it turns back on. Short cycling also results in uneven heating and accelerates wear and tear on the system, potentially leading to higher repair costs and a shorter lifespan for the unit.

When installing a new boiler, be sure it’s the right size for your home’s requirements. A qualified heating professional can perform a load calculation to determine the correct size.

3. Boilers Are Expensive to Run

While older boilers can be inefficient and costly to run, modern, energy-efficient models are much more economical. Manufacturers design these newer systems to use less fuel to produce the same amount of heat.

According to the U.S. Department of Energy, high-efficiency boilers, like condensing models, can save homeowners hundreds of dollars annually. While the initial cost of a new boiler may seem high, the savings on energy bills can make it a worthwhile investment.

4. Boilers Only Provide Heat, Not Hot Water

Some people mistakenly believe that boilers are only for heating, but they can also provide hot water for your home. Depending on the boiler type, it can supply both central heating and hot water.

Combination boilers are a popular choice for homeowners with limited space, as they consolidate heating and hot water into a single unit. Other types, like system boilers, are more suitable for larger homes. They use a hot water storage cylinder but still efficiently manage heating and hot water needs.

5. A Noisy Boiler Means It Needs Replacing

If your boiler makes strange noises, it doesn’t necessarily mean it’s time for a replacement. Noises like banging, gurgling, or whistling can be signs of air in the system, limescale buildup, or a blocked pipe. In many situations, these problems may be resolved by a routine repair rather than replacing the boiler entirely. If your boiler is making unusual sounds, it’s important to call in a professional to diagnose the issue. Often, a skilled expert can fix these problems without having to replace your boiler.

6. You Can’t Extend the Life of an Older Boiler

Older boilers may not match the efficiency of modern systems, but with proper care, they can continue to provide reliable service for many years. Tasks included in routine maintenance, such as cleaning, inspecting components, and addressing minor issues before they escalate, can all extend the life of an older boiler. In some cases, targeted upgrades to specific components, such as the burner system, may improve efficiency and performance.
