Find a Heating Engineer you can trust in Liverpool.

Ad hoc visits from your engineer to fix small issues with your heating system may actually seem cheaper and a lot more affordable, however when a boiler is ripe enough for a change these small issues are always never ending. Over some period of time, these small issues will inevitably get worse and the idea of “mend and make do will be an absolutely false economy. The best course of action in this sort of event is to find a replacement boiler to install as soon as possible. In this article, we’re going to give you some hints that’ll show you when your boiler needs to be replaced. Now let’s take a look!

✓ Insufficient hot water. Here, you’ll have to check the size of your hot water cylinder. It’s crucial to make sure that your boiler is rightly sized to power your heating as well as hot water circuit in line with your demands. You should always seek the advice of a heating expert who can recommend whether to fix or replace the boiler.

✓ Strange noises. It’s normal for components of the boiler to become worn or damaged over time. Replacing the particular component that’s causing the knocking or rattling may seem cost effective at first but more often than not, the noises usually signal a bigger issue which is likely to build up over time. Hence, it’ll be a lot more logical to replace the boiler itself.

✓ Regular repair of your boiler. It’s essential to have your heating system serviced by a Gas Safe engineer on an annual basis. However, when you have to call them more often than once a year for your yearly maintenance, it may be a wise decision to consider getting a replacement.

✓ Other events whereby you may need a new boiler includes when you can’t get the right temperature in your room, when the radiators don’t heat up as they should, when your boiler leaks and if your boiler still has a pilot light.

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.

If your boiler is leaking, there are some checks that you can do yourself. However, you should never attempt to repair your boiler yourself – only a Gas Safe-registered engineer should conduct repairs.

There are 3 main reasons why your boiler might be leaking: there’s a pressure valve fault, a temperature valve leak or corrosion in the system. An engineer will be able to spot the problem quickly, but in the meantime there are a few things you can do:

Check the pipe fittings

If your boiler is leaking water around the pipe fittings, it could be an installation fault and you should get in touch with the engineer that fitted it. You can check the pipe fittings by drying the area then waiting to see if the water appears again. If it does, you may be able to do a ¼ turn of the pipe to stop it. However, you should still call the engineer that installed it to ask them to check the PTFE tape on the inside.

Inspect the seals

Over time, the rubber seals on a boiler can start to perish, so if you have an old boiler this could be the source of your leak. If you have a new boiler, it could be caused by your boiler running over pressure.

Heat exchanger corrosion

Unfortunately, if a boiler engineer discovers that the boiler is leaking water from the heat exchanger, this is the end of the road for your system. The heat exchanger is the most expensive part of your boiler, so it makes more financial sense to replace your boiler with a newer, more efficient model rather than try to replace it.

How Much Is A New Oil Boiler?

An oil boiler is a very useful tool for providing both central heating and domestic hot water to a property by burning oil. As a result, they’re simply one of the most common alternative heating methods used in homes throughout the UK. If you’re not connected to the mains gas network, then it’s a no brainer to depend on another fuel for central heating purposes - oil. Therefore, if you’re looking to get a new oil boiler, you’d need to identify the size and price as there are a plethora of models to select from - all coming in a large array of sizes and prices. We’ve put together some important details about the prices to give you a good insight on the amount you’d have to incur to procure a new oil boiler. Let’s have a look!

Generally, gas boilers are less expensive when compared to the oil boilers. You can get a wide range of gas boilers from a starting price of £500 to £600, meanwhile you’d rarely find an oil boiler less than £1000 in the market.

The lowest priced oil boilers are typically priced starting from around £1000, and the best in class oil boilers normally costs more than £3000.

The rule is, the most expensive oil boiler is typically the largest one. So to have an idea, the bigger it is, the more money you’d have to spend. Oil boiler’s size is measured in kilowatts (kw), which showcases its power. To determine the type of oil boiler that best suits your home, the most significant factor would be the size as a bigger home will require a bigger oil boiler. You have an option to choose between the combi, conventional and the system models of oil boiler.

If you choose to install an LPG boiler, you’ll need to find an LPG supplier. They’ll deliver fuel to you every time your storage tank runs low. You can even rent a storage tank from them if you don’t want to buy one. Make sure you know who your local suppliers are and where they are based.

Modern oil boilers do not require a lot of maintenance. OFTEC recommends that oil boilers are serviced and inspected every year. This keeps them running as efficiently as possible and will ensure any issues with your boiler are identified before they cause bigger problems. This servicing is also vital because of the increased risk of carbon monoxide leaking from a poorly maintained boiler.

How Long Does A Boiler Service Take?

Servicing of your boiler is a very crucial activity which does not only help in keeping your heating system in a top condition, but also assists in ensuring the safety of both you and your loved ones. If you carry out a regular boiler service you’ll be able to identify any possible fault your boiler may have on time before it leads to a more serious issue or even a boiler breakdown. As a result, you’ll be able to save yourself some time and money, but more importantly will save you from any dangerous risk that may result from gas leak in a boiler. The best time for a boiler service is in the summer when you’d probably would not really need the system, so you can take advantage of that as well as the possible lower boiler servicing cost during this period.

Before we look into the amount of time a boiler service should take, let’s first consider what should be done during a boiler service.

✓ Visual inspection. This is a check carried out by the heating engineer to ensure your boiler still meet the existing standards and requirements while also looking for any faults.

✓ Removal of boiler casing. There’s the need to ensure everything is working just fine and also to clean the boiler’s interior. These inspections should include the burner, heat exchanger, main injector and spark probe.

✓ Flue check. This involves making sure that there’s no form of obstructions in the flue terminals as also to ensure that the flue is well installed.

✓ Gas pressure check. This involves making sure that the boiler working with the appropriate pressure.

✓ Boiler fired up. This involves checking for any operating issues.

Generally, a boiler service should be completed within 30 minutes, however this time may vary largely depending on the brand and model.
