​Trust the Boiler Repair Experts

Your home's boiler system is a critical component of your comfort, particularly during the cold winter months. Unlike forced-air systems, boilers heat water that circulates through radiators, baseboards, or radiant floor systems to provide consistent, comfortable heat throughout your home.

This type of heating offers several advantages including:

• Even temperature distribution.

• Improved air quality (as no dust is being circulated).

• Quiet operation.

However, like any complex mechanical system, boilers can experience issues that affect their performance and efficiency.

Understanding how your boiler works and recognizing the early signs of problems can help you maintain a comfortable home and avoid costly emergency repairs.

At Sears Home Services, we specialize in all types of boiler repair and maintenance, regardless of where you purchased your system. Our trained Sears repair service technicians are equipped to diagnose and repair issues with gas boilers, electric boilers, and hot water boilers from all major manufacturers.

When you need expert boiler repair services, we're just a call away.

Common Boiler Problems and Their Causes

Recognizing the signs of boiler problems early can help prevent more extensive damage and costly repairs. Here are some of the most common issues homeowners face with their boiler systems:

No Heat or Hot Water

When your boiler fails to produce heat or hot water, several factors could be responsible:

• Thermostat issues: Incorrect settings, malfunctioning thermostats, or power supply problems can prevent your boiler from activating properly.

• Burner ignition failures: In gas boilers, a failed ignitor or a pilot light that has gone out will prevent the system from heating.

• Broken pumps or airlocks: These can interrupt the circulation of hot water throughout the system.

• Pressure problems: If the pressure is too low or too high, your boiler may shut down as a safety measure.

• Frozen condensate pipes: During very cold weather, condensate pipes can freeze, causing the boiler to shut down.

Unusual Noises

Strange sounds from your boiler often indicate specific problems:

• Kettling: A rumbling noise similar to a kettle boiling, usually caused by limescale or mineral buildup on the heat exchanger.

• Whistling: Often indicates air in the system or pump problems.

• Banging or clanking: May suggest air in the system, pump issues, or loose components.

• Gurgling: Typically indicates air in the system that needs to be bled out.

Leaks and Drips

Water leaking from your boiler can indicate several issues:

• Pressure relief valve activation: If pressure is too high, this valve releases water to reduce it.

• Broken internal components: Pumps, pipes, or tanks may develop cracks or loose connections.

• Corrosion: Over time, components can corrode, leading to small leaks.

• Seal failures: Seals around pumps and valves can deteriorate and allow water to escape.

Pressure Issues

Proper pressure is essential for boiler operation:

• Low pressure: Often caused by leaks in the system, recently bled radiators, or a failing pressure relief valve.

• High pressure: May be due to a filling loop problem, expansion vessel issues, or a faulty pressure relief valve.

Radiator Problems

Issues with radiators can affect overall system performance:

• Cold spots: Air trapped in radiators prevents hot water from circulating properly.

• Uneven heating: Some radiators heat while others remain cold, often due to balancing issues or blockages.

• Complete failure to heat: May indicate pump problems, valve issues, or air locks in the system.

To fix a boiler problem, schedule repair service and we'll send a technician to your home to resolve the issue.

DIY Troubleshooting Steps Before Calling a Professional

While many boiler issues require professional attention, there are several troubleshooting steps homeowners can safely take before calling for service:

1. Check Your Thermostat

• Ensure it's set to "heat" mode and at a temperature higher than the current room temperature

• Replace batteries if the display is dim or blank

• Verify that the thermostat is properly communicating with the boiler

2. Inspect System Pressure

For most residential boilers, the pressure gauge should read between 1 and 1.5 bar when cold. If pressure is outside this range:

• Low pressure: You may be able to repressurize the system using the filling loop (consult your boiler's manual for specific instructions)

• High pressure: Allow the system to cool completely, then check if pressure drops naturally

3. Bleed Radiators

If radiators have cold spots (typically at the top):

• Turn off your heating system and allow radiators to cool

• Use a radiator key to open the bleed valve slightly

• Close the valve once water begins to escape

• Check boiler pressure after bleeding radiators, as this process can lower system pressure

4. Reset Your Boiler

Many modern boilers have a reset function:

• Locate the reset button on your boiler (consult your manual if unsure)

• Press and hold according to manufacturer instructions

• Allow the boiler to go through its restart sequence

5. Check for Simple Blockages

For condensing boilers, check if the condensate pipe (usually a white plastic pipe) is frozen or blocked:

• Inspect the external portion of the pipe for ice during cold weather

• If frozen, apply warm (not boiling) water to thaw it

• Clear visible blockages if accessible

6. Verify Fuel Supply

For gas boilers:

• Check that the gas supply shut-off valve is open

• See if other gas appliances are working to determine whether your home’s gas supply is okay

• Look for any obvious issues with the igniter or pilot light (if visible)
