Oil Boiler (Repairs or Servicing) in Knebworth

How Do You Bleed An Oil Boiler?

Bleeding air between the oil supply and an oil fired boiler’s burner is a process that’s often required when the system has run out of oil and the burner has stopped working. Upon refilling the oil tank, the air that has been trapped within the oil pipe when empty has to be freed to ensure that the oil reaches the burner and allows it to start again. So how do you go about the process?

First and foremost, it must be noted that it’s always better to be on the look out for the amount of oil in your fuel tank and get it refilled before it runs out. However, if it does run out, you can take the following steps:

• Identify the burner

The burner is a red plastic cover and it’s usually positioned on the bottom part of the boiler (mostly inside the boiler casing). Once identified, inspect it to see if the lockout button is lit red. If yes, simply unscrew and detach the burner’s red case using a flat head screwdriver.

• Identify the oil pump

You’ll find the oil pump on the burner’s left side which is connected to the flexible oil line. Once done, simply locate the 3 inches long hexagonal stem protruding from the pump and with a small threaded plug screwed into the end. Unscrew the plug in just half a turn ( 180 degrees) with a 4mm Allen Key. At this stage oil will be released, do ensure there’s a cloth or rag underneath the plug to grab the oil freed.

• Press the lockout button

This is the next and final step. However it’s also crucial to note that the burner fan will run for about 12 seconds and discharge some oil from the loosened plug which you can grab with a cloth or rag. Immediately you hear a buzzing sound, use the Allen key to tighten the plug. If enough air has been bled, the system will fire. But if not, then you’ll have to repeat the process again.

How Much Oil Does A Boiler Use?

Are you also interested in knowing the quantity of oil that a boiler consumes to heat up and keep a house warm? Well, you’ll find the answer here. There are so many influencing factors that determines the quantity of oil that’ll be used by a boiler. These factors include the number of hours they’re subjected to use on a daily basis, the boiler’s size as well as how efficient it is. Another factor is how you use your boiler, whether it’s only to provide heating or to provide both heating and hot water will as influence the quantity of oil your boiler uses. As a result, it’s almost impossible to provide an accurate estimate of the amount of oil that an appliance would require to keep running effectively.

In general, to provide a rough estimate, a mid sized oil boiler appliance could make use of up to 3.5 litres of oil per hour when full, but if it’s a large appliance, then it can burn up to 4 litres of oil per hour. However, it should be noted that this is only when the boiler is operating flat out. In the event whereby the water inside the heating system is already hot and the boiler is only working to maintain the level of warmth, much less quantity of oil will be used. And as expected, there will also be times in which your boiler will not be on, and therefore no oil or fuel will b used.

Your home’s size as well as how properly insulated it is can also be a significant influencing factor here. As you would have guess a big home and/or poorly insulated will use up more oil because it’ll be harder to heat up or keep warm. Overall, for some households, 1000 litres of oil will be sufficient to get them through the year, whereas the same quantity may not be enough to get other households through just the winter months.

How To Make Oil Boiler More Efficient?

During the winter months when the nights get darker and colder, it’s more likely your oil gets used up a lot more quickly. This can be very worrisome as it implies having to spend more money to refill. So what exactly can be done to make your oil boiler more efficient and save you some money?

When a full servicing is provided for your oil boiler, checks are made to ensure that all components are functioning the way they should while also identifying the bad or worn parts that may be hindering your oil boiler from functioning in an effective manner. As a result, it helps you see to the fact that your boiler is not consuming more than necessary to make sure your oil boiler lasts longer.

• Set Your Thermostats Correctly

When you set your room thermostats and thermostatic radiator valves (TRVs) the right way, you’ll be sure to get a comfortable home without having to make use of much fuel.

• Consider Smart Technology

If you decide to make use of smart technology like Nest or Hive, you can save more money when compared to their more conventional counterparts. These smart technologies incorporate highly advance intelligent systems to get more familiar with your lifestyle, habits as well as heating operations in order to ensure optimum efficiency at all times.

How Long Does It Take To Service An Oil Boiler?

Are you about to service your oil boiler and wondering just how long it would take to completion? Well, you should first know that during an oil boiler service, there are a wide range of things that needs to be checked. As a result, the service can actually take some time and even more, depending on the present condition of your oil boiler.

During a boiler service, your qualified heating engineer will carry out the following tasks:

• Detach and clean both the burner and fan.

• Examine the combustion chamber rope seal.

• Wipe clean and descale baffles.

• Wipe clean and descale the main heat exchanger

• Detach, clean and replace turbulators

• Examine the combustion levels after cleaning.

He’ll also perform some tank and system checks which includes:

• Inspecting and cleaning condensate

• Testing the fire valve

• Cleaning or replacing the filter

• Cleaning the condense trap

• Conducting a thorough inspection of the tank and oil supply pipe to identify possible damages, deterioration as well as debris.

• Pressure testing the oil supply pipe at the point where it goes underground.

• Examining the system pressure.

With all the aforementioned activities and more, an oil boiler service may take relatively longer period of time when compared to it’s counterpart - gas boiler. This is mainly due to the fact that the boiler itself requires a thorough inspection as well as the oil tank where the fuel is being stored. You get your gas through the mains supply, however oil must firstly be stored inside the tank then filled up when it’s almost low. The oil tank will be inspected to identify possible leaks, bulging, corrosion as well as water.

So generally, an oil boiler service should take between the range of 1 to 2 hours to be completed.
