Heating Engineer FAQs

how do electric boilers work?

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.

what is a condensing boiler?

Condensing boilers are the in-thing when it comes to modern heating systems in UK homes and across the globe for a good reason. This is primarily due to the fact that condensing boilers happens to be highly efficient as it enables the fuel you’re burning to heat up your home go a lot further. Having a new high efficiency condensing boiler rather than an old G-rated non condensing boiler will not only enhance your heating controls, but also save you a lot of money annually. In this article, we’re going to take you through the basics of a condensing boiler. Let’s take a closer look!

This is purely due to the fact that these condensing boilers happens to make a better use of the heat they’re able to produce from burning fuels like oil or gas ( in other words, they require less heat from the burner, which makes them a lot more efficient).

So how does a condensing boiler work? Unlike a non-condensing heat-nly boiler, some heat will be wasted in form of hot gases which are released from the flue. Meanwhile a condensing boiler captures some of the heat from these gases and puts them to use for heating up water that’s coming back from your central heating system. As a result, it requires just a minimal heat from the burner which make the boiler more efficient.

how do you bleed an oil boiler?

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 boiler do I need?

The size of boiler you need will depend on the size of your commercial property, how many radiators and bathrooms you have and how appliances willl need hot water at the same time. The boiler size refers to its output, which is measured in kilowatts (kW), rather than the actual dimensions. Speak to your boiler engineer about which boiler is suitable for you, as if you have more than one bathroom or a lot of people in your home a combi boiler might not suit you.

Can I repair my own boiler?

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.
