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

If you get the right size boiler for your home 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.

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 property is not connected to a gas main, oil boilers are a great alternative to gas boilers and more efficient than LPG alternatives. They can also be paired well with renewable sources. However, if your property is connected to the gas mains, there is generally no reason to switch to an oil boiler, as you will need to have oil delivered to an extra storage tank.

How Do Electric Boilers Work?

Electric boiler are installed in residential, commercial and industrial properties to serve as a reliable source of heat. Unlike other types of boilers that depends on fossil fuel burning to be able to operate, electric boilers are fuelled by electrical energy which ultimately makes it more reliable and powerful compared to its counterparts. This heating option was basically provided for home or property owners who don’t have an access to the main gas supply.

So how does an electric boiler work? Basically, an electric boiler work by heating water. Once heated, the hot water supply is then distributed to various areas across the house or property. In order to achieve the best possible efficiency at the lowest possible costs, new model electric boilers are installed by licensed and professional boiler fitters with the help of a microchip control system. Meanwhile, the microchip control system functions to oversee the management of both temperature level as well as output.

Unlike other types of boilers such as a gas boiler, electric boilers only require minimal service. If you own a gas boiler, it’s crucial to ensure that it’s serviced every single year by a licensed and reliable professional that’s into boiler repair services. During the checks and maintenance services, the gas boilers would need to be checked for possible gas leaks, as well as ventilation poisoning and other problems.

Overall, electric boilers are considered to be one of the most environment-friendly heating system which is more affordable to install in your property than a gas boiler. It represents the most ideal option for homes with gas boiler issues as well as those that are not connected to the main gas supply. What’s more? Electric boilers are also one of the best options for wet central heating and under floor heating.

How Much Does A Boiler Repair Cost?

An annual service for your boiler might not seem important and may be easy to postpone to another day, but when it happens to breakdown due to lack of adequate attention, this can be quite painful and also costly.

Before you start thinking about the cost of repairing your boiler, the first thing you’ll need to confirm is whether or not your boiler is still covered by the manufacturer’s warranty. You’d be amazed some warranties can last for as long as 12 years, if yours is still on then you can save yourself a huge amount of of money on your boiler repair. As a result, it’s always crucial to keep the details of your warranty somewhere safe, so you can read them from time to time. You never can tell when the rainy day will come!

Most boiler warranties will require your to get your boiler serviced on an annual basis by a licensed and qualified technician. The cost of an annual boiler service is affected by the time of the year you wish to get it done. When boilers are less useful during the summer months, an annual service is usually relatively cheap when compared to the cold months. Around this period, a boiler service will normally cost within the range of £100 to £150, however for a more accurate quote it’s advisable to contact a couple of professionals and compare their quotes.

The cost of getting a boiler repaired will be affected by a couple of factors including your boiler’s make, the age of the boiler as well as your location and how urgent you need it done. If you have a dead boiler, the cost will typically range from £96 to £348 and a boiler displaying a fault code will cost within the range of £90 to £275. Generally, repairing a boiler will cost within the range of £90 to £400 based on the several factors stated above.

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 home or property, it’s only reasonable not only to expect the boiler to warm up your home 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 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.

When your boiler is being replaced you won’t have hot water or central heating. If you don’t mind this you can stay in your home, and use portable electric heaters if needed. Most installers undertake a power flush before installing a new boiler now and this can cause muck and debris from the pipework, so you may wish to get out of the way while this is happening!
