How to Maintain Your Boiler

Is your home’s heating equipment ready for a New England winter?

boiler Medway, MAWhile the leaves are changing, the afternoons are crisper and the pumpkin spice is beginning to waft, you can start a countdown to the icy-cold weather to come. At the start of 2025, we experienced the harshest winter that we’d had in several years. Your home’s heating system probably worked extra hard to keep you and your family comfortable.

As we prepare for winter’s return, it’s important to consider what you need to do to keep your heating system running dependably and efficiently. The HVAC experts at TF Complete Heating & Cooling are always available to help, and in this article, we’ll discuss proper pre-season maintenance for boilers.

How Does a Boiler Keep Your Home Warm?

A boiler works by heating water to produce either hot water or steam, which is then distributed through a network of pipes to radiators, baseboards or radiant floor systems, effectively warming your home. Once the water or steam cools and condenses, it cycles back to the boiler to be reheated and continue the process.

To keep your boiler running efficiently and effectively, here are five essential maintenance tips:

1. Ensure All Radiators Are Fully Open

If one of your radiators isn’t heating up, check the knob to confirm it’s turned all the way to the open position. Radiators operate on a simple system: they are either fully open or fully closed.

2. Bleed Your Radiators Annually

Over time, air can become trapped inside radiators, reducing their performance and causing clanging or gurgling noises. Bleeding your radiators once a year is a quick and easy fix. Locate the bleed valve at the top of the radiator, open it and let the trapped air escape. Once water starts to flow out, close the valve.

3. Flush Your Boiler Annually

Sediment and sludge can build up in your boiler’s tank, affecting its efficiency and accelerating wear and tear. Flushing your boiler once or twice a year can fix the issue.

To flush your boiler:

  1. Turn it off.
  2. Place a bucket under the drain valve and open it, allowing the hot water to drain out.
  3. Continue draining until the water runs clear.
  4. Refill the tank to the proper level using the cold water intake valve.

Please refer to your boiler’s owner’s manual for specific instructions.

4. Optimize Your Thermostat Settings

Maximize comfort and efficiency by using a programmable or smart thermostat. These devices allow you to balance warmth during winter with energy savings, extending your boiler’s lifespan.

According to the U.S. Department of Energy, you can save up to 10% annually on heating and cooling costs by lowering your thermostat by 7-10°F for eight hours a day. Program your thermostat to adjust temperatures while you’re asleep or away from home for the best results.
