Re-pressurising your boiler means that you allow more water to enter system via the filling loop. It can be easy to re-pressurise your boiler yourself. Always check your manual, but there are some simple steps you can take to restore pressure to your boiler:

• Switch off your boiler and let it cool completely

• Make sure both ends of your filling loop are attached

• Open both valves to allow cold water into the system – you’ll hear it start to move

• Look out for your pressure gauge to show 1.5 bar

• Close both valves

• Switch your boiler back on

• Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!

When it comes to gas boilers, this is one of the most frequent questions that always pops up and for a good reason. When you invest a considerable amount of money to acquire and install a gas boiler in your business property, it’s only reasonable not only to expect the boiler to warm up your property efficiently, but also to do so for a long period of time. If you’ve just bought or about to get a new gas boiler, it’s likely you won’t have to worry about getting a replacement for a lengthy period of time. Several commercial gas boilers will last for anywhere between 10 to 15 years on the average. However in the event whereby you have an existing one that’s fast approaching the end of it’s useful life, then you should know the time go get a new gas boiler is just around the corner, and the earlier you make the purchase, the better (to avoid any surprise breakdowns that’ll leave your home super uncomfortable).

Just like any other home appliance, it’s a fact that an older gas boiler ( especially those that have been installed over a decade ago) are significantly less efficient that the new modern ones. When the older versions were manufactured is a completely different time to now as both technology and climate concerns are wide apart. So when your existing boiler is approaching the end of it’s useful life, it’ll be wise to start saving up to cover the cost of getting a new one. However, if it’s only about 5 years ago your boiler was installed, it’s highly likely to still be very efficient.

During the cold months ( winter), there’s a high chance for a more frequent occurrence of faults and breakdowns of your boiler as this is the time in which more strain is being placed on the device. Unfortunately, this is exactly the time in which you’d wish to derive maximum benefits from your boiler to keep you warm all through the winter. As a result, home owners are given no other option than to pay the mega boiler repair bills to keep themselves warm and cosy all winter long. There is, however, an option which can greatly soften the blow and that’s having a boiler breakdown cover.

Boiler breakdown cover provides coverage for cost of hiring an engineer to get your boiler back to a top condition while also paying for the parts as well as labour needed to resolve the boiler’s fault. To select a boiler breakdown cover, you should take into account factors like whether or not the policy provides coverage for limited or unlimited call-outs within the coverage period. You should also ensure to go through the terms and conditions of the cover if you can stake a claim if your boiler were to be damaged by a different thing in your central heating configuration or a persistent fault.

There are an array of boiler breakdown package types with little differences which relates to one or more of the following:

• The package monthly cost

• The call outs excess to be paid

• The nature of the helpline. It may be a 24/7 service or just a few selected hours of the day.

Therefore, to answer the question of which boiler breakdown cover, you’d have to compare the different packages to determine the most suitable one for both your needs as well as pocket.

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.

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

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.

Biomass boilers can be designed to work with other kinds of heating. The most common of these is solar thermal. This is a popular renewable energy pairing. Solar thermal heating will meet your hot water needs during the summer while a biomass boiler can operate as a backup during the winter when solar thermal panels do not perform as well.

If you get the right size boiler for your business and you get it serviced regularly, your boiler could last up to 15 years. It may even last longer than this, but you’ll find that your boiler begins to become less efficient as it gets older. Also, as technology improves, a boiler older than 15 years may not be the most efficient one on the market.
