Find a Heating Engineer you can trust in Kingston Upon Thames.

If your boiler is making strange noises or smells, or doesn’t seem to be working properly, it may need replacing. Boilers usually last about 10-15 years. Even if your boiler is working normally, it’s worth replacing when it gets this old. An annual check will establish if there are terminal problems with a boiler that cannot be fixed.

How Often Should You Service An Oil Boiler?

If you have an oil boiler, you probably know the importance of having it serviced to ensure its proper functioning, prolong its useful life as well as ensuring the safety of your home. However, the question that most frequently arises is how often would one need to service the prized hating system? If you’re also looking for the answer to this same question, then you’ve come to the right place. To make sure your oil boiler is running smoothly, safely and efficiently, it should be serviced as often as once in a year. You certainly do want to know the numerous disadvantages of failing to service your boiler. Not only will neglecting your oil boiler service result in possible faults as well as higher energy bill caused by its inefficiency, but can also lead to your warranty ending early.

Therefore, you should ensure your oil boiler is serviced by a qualified heating engineer on an annual basis to make sure it’s running just as it should. This will give you peace of mind knowing you wouldn’t be spending huge bucks on possible repairs and in some cases, replacements.

As a landlord in the UK, it’s a legal requirement to make sure that your oil boiler and flue system is services on a yearly basis in your rental property.

Unlike a gas and oil boiler, an electric boiler do not require the same level of maintenance or servicing. However, it’ll be a nice move to ensure that it’s also checked once in a while.

Overall, it’s important to note that failure to service your oil boiler on a yearly basis can give rise to multiple risks. These includes a rise in energy bills, carbon monoxide leak, fault that can cause boiler breakdown as well as an expensive repair or replacement bill.

What Size Of Oil Boiler Do I Need?

When it comes to oil boilers, there are three main types - the combi, system and conventional. Within these types, you’d discover there happens to be a wide range of sizes to choose from. First and foremost, we must note that the size has to do with the amount of energy they offer to your heating and hot water system rather than the physical dimensions.

The rule of thumb is, the larger your house (which implies the more hot taps, radiators and showers), the more powerful (bigger) the oil boiler you’d require. For instance, a four-bedroom apartment with three showers occupied by a family of four will definitely need a more powerful boiler than a a bungalow featuring a single occupant.

It is, however, important to also note that it’s not all about going for the biggest oil boiler. If you decide to choose an oil boiler with a much bigger capacity that needed, not only will you be wasting money on the initial purchase as well as installation, but also lose money operating it. And in a converse scenario, if you go for the cheaper and lower-powered oil boiler in an attempt to save up some money, you’re most likely to end up with tepid radiators while also frequently running out of hot water. Hence, the importance of determining the appropriate size of boiler for your particular household before purchase.

To determine the appropriate size, determining the number of bathrooms, radiators as well as the total number of people living in the property would be a step in the right direction.

Numbers of Radiators Combi System Boiler Regular

Up to 10 24 to 27kW 9 to 18kW 9 to 18kW

10 to 15 28 to 34kW 18 to 26kW 18 to 26kW

15 to 20 35 to 42kW 27 to 40kW 27 to 40kW

No. You must never repair your own boiler – only a Gas Safe-registered engineer can do any work on your boiler. You can do simple DIY tasks to repressurise your boiler or stop a leak, but if you have to remove the outer casing of the boiler or touch the flue then you must get a qualified boiler engineer to take a look at your central heating system.

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.

The Oil Firing Technical Association or OFTEC operate a competent persons scheme to certify installers. It’s always recommended to use an installer with this certification as it proves they have the training and expertise to properly install your boiler and give you realistic advice on the efficiency of your system. Also, OFTEC registered installers offer Workmanship Warranties to protect you if there are any problems after installation.

How Much Do Electric Radiators Cost?

If there’s an age-long question that doesn’t seem to go away any time soon it’s how much do electric radiators cost? Although it would be perfect to offer an exact figure you can actually work with as the cost of running your heating system, but unfortunately you’ll have to consult a clairvoyant individual to get that. The question is almost synonymous with asking to know what your utility bill will be this month or the next. This is an answer that’s specific to each household, so it would be impossible to provide an answer that applies to all households in the UK. This is because there are several influencing factors that affects what the final cost of your household’s electricity bill will be. Let’s take a look at these factors!

• The size of the room you want to heat. As you would have guessed, the larger the room, the higher the amount of energy that’ll be incorporated, which means a greater electricity bill.

• The age of your house. There’s a high possibility your household ( if it’s an old one) lacks sufficient insulation which makes it less energy efficient, except you’ve already made some necessary changes.

• Your individual needs. Depending on your personal requirements, you electricity bill may be greatly influenced to be higher or lower. And the more people you have in your home, the more the energy you’re likely to consume.

• Time of the year. During the winter months, you’re likely to use a lot more electricity and heating because the weather tends to be colder.

• Your property’s exposure to natural elements. For instance a terraced home with houses on either side will be able to retain heat much longer and there less electricity and heating than a fully detached home.

Breakdowns of boilers are quite common during the winter months and are usually very expensive to repair when this occurs. According to the research carried out recently by uSwitch, repairing a boiler can cost an average of about £314 with a figure over 20 percent of homes experiencing various heating system issues last year.

To answer the question of whether or not your existing home insurance will be enough to cover the boiler breakdown, the answer is probably not. This is due to the fact that heating system faults or breakdowns is a very common occurrence and as a result of poor maintenance practices as well as a high repair cost, several insurance companies often remove it from their home insurance policies.

Generally, you’d be given an option of what is termed as “emergency home cover which is an add on or extra to your home insurance policy. Luckily, this add on is quite inexpensive and may be as little as £4 or £5 per month. Depending on your need or budget, you can also purchase the add on as a “stand alone from your current insurer or another company. However, the stand alone option is usually more expensive.

The emergency home cover normally provides coverage for the boiler repair cost and few times, the rest of the central heating system as well. Being fully aware how important a boiler can be, insurance companies usually deliver a rapid response service as suggested in the name, “emergency home cover. However, the maximum pay out for call out charges is capped at a particular amount which usually ranges from £500 and £1,000. Apart from the call out fees, the emergency cover also includes a limit on the pay out amount for future required repairs of heating systems which includes both parts labour.
