A well-functioning boiler is essential for keeping homes and businesses warm, especially during harsh winters. However, like any other appliance, boilers can develop issues over time. At ASW Instal, we specialize in diagnosing and repairing boiler problems quickly and efficiently. Here are some of the most common boiler issues and how our expert team resolves them.
1. No Heat or Hot Water
One of the most common boiler issues is a lack of heat or hot water, which can be caused by several factors such as a broken diaphragm, faulty thermostat, or low water pressure. ASW Instal technicians perform a thorough assessment to identify the root cause. If the diaphragm needs replacement or the thermostat is malfunctioning, we replace the faulty parts immediately. In cases of low pressure, we inspect for leaks and repressurize the system to restore proper functionality.
2. Boiler Leaks
A leaking boiler can lead to significant damage if left unaddressed. Common causes include corroded pipes, faulty seals, or a broken pressure valve. Our team carefully examines the boiler to determine the source of the leak. We replace damaged components, reinforce pipe connections, and ensure that pressure settings are within the recommended range to prevent future leaks.
3. Strange Noises Coming from the Boiler
If a boiler starts making unusual noises such as banging, whistling, or gurgling, it may indicate trapped air, low water pressure, or limescale buildup. Our experts at ASW Instal bleed the radiators to remove trapped air and check the system pressure to ensure it’s at the correct level. If limescale buildup is the issue, we perform power flushing to clean the system and prevent further problems.
4. Pilot Light Keeps Going Out
A faulty pilot light can be caused by a broken thermocouple, a draft blowing it out, or a buildup of debris in the burner. Our technicians clean the pilot light assembly, check for gas flow issues, and replace defective thermocouples to ensure reliable operation. We also inspect ventilation areas to prevent drafts from affecting the pilot light.
5. Boiler Losing Pressure
If a boiler is losing pressure, it often means there is a leak in the system, a faulty pressure relief valve, or an issue with the expansion vessel. ASW Instal professionals conduct a pressure test to detect any leaks and repair them accordingly. If necessary, we replace the pressure relief valve or recharge the expansion vessel to restore optimal pressure levels.
6. Radiators Not Heating Properly
Uneven heating in radiators is usually due to trapped air, sludge buildup, or a faulty pump. Our team flushes the system to remove blockages and bleed the radiators to release trapped air. If the pump is malfunctioning, we either repair or replace it to ensure even heat distribution throughout the home or building.
7. Frozen Condensate Pipe
During freezing temperatures, the condensate pipe that removes waste water from the boiler can freeze, causing the boiler to shut down. ASW Instal’s technicians quickly defrost the pipe using safe methods and insulate it to prevent future freezing issues. This ensures uninterrupted heating even in extreme winter conditions.
8. Thermostat Issues
A faulty thermostat can lead to inconsistent temperatures or a complete failure to control heating. We test and calibrate thermostats to ensure they are accurately detecting room temperatures. If necessary, we recommend and install smart thermostats for enhanced control and energy efficiency.
9. Boiler Switching On and Off Repeatedly
A boiler that frequently turns on and off, known as short cycling, can be caused by thermostat issues, low water pressure, or a blocked heat exchanger. Our technicians inspect the system to determine the cause and resolve it by cleaning or replacing the heat exchanger, adjusting water pressure, or recalibrating the thermostat.
10. Boiler Overheating
An overheating boiler can be a safety hazard, often resulting from limescale buildup, a faulty thermostat, or a blocked pump. ASW Instal experts diagnose the issue and perform necessary repairs such as descaling, replacing defective components, and ensuring proper water circulation to prevent overheating.
