There can be a list of reason why your boiler fails to produce heat or hot water, from airlocks and motorised vale failure to low water levels. A qualified technician can identify any issueand quickly replace failed parts. However, what you need to find out is whether the boiler suppliers provide gas safe engineers. Gas safe engineers have all the required technical knowledge and hold a license to install or service your boilers legally.
Now, let us see what some of the common issues that customer's face
As it restricts the water flow, when the water boils, it creates kettle sounds. Remember, boilers can crumble at any point. The abrupt pressure on its component causes the disruption – when a household requires heating and hot water.
Tips to Choose the Perfect Boiler Suppliers
You want to be sure that your family is safe and warm. Therefore, it should be your priority to ensure that your boiler works effortlessly. Boilers use different fuel type such as natural gas, oil, electricity, propane or wood to produce heat.
You have the advantage to warm up your dwelling through radiators, baseboard convectors, radiant floors, or fan-forced coils. However, you may want to go for a boiler replacement if the boiler is older than ten years.
If, on a calculation, you spend more on repairs than in the past, it time to get a new one. In fact, the latest models are more efficient and help save your money on energy bills.
When going for a boiler replacement service, two things matter the most.
- • Size
- • Efficiency
The capacity of any boiler is measured in BTU (British Thermal Units). BTU is the energy required to increase the temperature by one degree Fahrenheit for one pound of water. Every building has a unique BTU requirement.
This is generally based on the geographical locations and climate, the quality of insulation in the walls and ceilings and the number of doors and windows in the building.
Roughly, the calculation goes like this- 50 BTU per square foot of interior space in colder places.
When purchasing a brand new boiler, don't forget to check all the specifications recommended by the local authority. You need to review the AFUE rating (Annual Fuel Utilization Efficiency Rating). It states how effective the system is in transforming fuel into heating energy.
Boilers come with an AFUE rating. Boilers with 85% are regarded as a high-efficient system. You will also come across certified boilers. This means they meet strict energy-efficiency guidelines as set by the government.
- • Oil furnaces today have AFUE ratings of 80 to 90%
- • The gas equivalent rates between 89 to 98%
- • Condensing boilers has a rating over above 95%
- • Electric boilers have more or less 100%
Electric boilers come with zero-waste. In fact, these should be the best option in countries where electricity cost is economical.
Significance of Venting Your Boiler
Power and direct vent boilers use fans either through the roof or sidewall vent. But, on Chimney-vented boilers, exhaust happens naturally through the chimney. Power vent airs from inside; therefore, they need open rooms for installations. Condensing boilers have special venting requirements. This is due to the acidity of the condensate that they produce,
Troubleshoot Your Boiler
When you install a boiler, the boiler supplier will equally guide you about the common causes behind malfunctions. Before troubleshooting, these are some maintenance you can run as suggested by the experts.
Checking the Thermostat
The thermostat of the boiler should be above room temperature.
Check the Circular Pump
Touch the pump and see whether it's warm or not. If you can find out that the pump is not running or is cool, you need to check the circuit breaker for the boiler quickly.
Test the Motor Temperature
Find it whether it's hot or not. If the motor is heated, you'll face the issue on the run capacitor, the motor or the pump. The thermostat or the circulator relay will be a concern if it's cool.
Test the Temperature /Pressure Gauge
Almost all the gauges come with a red line. The temp/pressure should be greater than zero but shouldn't cross the red marking. When the temperature and pressure look normal, the boiler system has air in it. Such issues are prevalent on older manual air eliminators. However, the company allows you to replace it with a modern, automated float type air eliminator.
Review the Burners
Examine the burners light when the vent damper is open or if the inducer fan is running. If the pilot fails to light up, the vent pipe could possibly be obstructed.
If the pilot does not light and stays lit, the pilot assembly or the flame sensor requires cleaning. The thermocouple or boiler control needs to be replaced.
When the pilot lights up and stays lit for some times, the main burner should ignite. Likewise, if the main burner does not come on, the boiler control or gas valve needs replacement.
Overheating & Noise
If there's insufficient air circulation in the primary circuit, you need to vent the system. Else, there could be something that's obstructing the piping system. Check for any external objects that could be causing turbulence.
Purchasing a boiler is undoubtedly a big decision. Getting help from your local boiler supplier is one of the best things that you can do. At Home Efficiency Surveys, we are gas safe registered and provide expert boiler installation and maintenance services.
