Heating Engineer FAQs

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!

If you’re interested in getting a greener and more efficient boiler, you simply can’t afford to look beyond a high efficiency condensing boiler. 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.

You should take note that all new modern boilers are condensing boilers. Therefore if you’re planning to replace an old boiler with a new one, you’ll definitely be buying a new condensing boiler and benefit from all the efficiency and savings that comes with it.

how to fix a broken boiler?

How To Fix A Broken Boiler

To fix any problem when it comes to home appliances, the first step is always to identify the problem while also carrying out thorough checks - a broken boiler is not an exception. Putting enough time and effort in diagnosing a problem can go a lot way to save you both time and money. So here are some of the steps you can take to fix your broken boiler before you put a call out to a licensed engineer.

✓ Check to confirm if your pilot light is on. Whenever you’re facing some issues with your boiler, this should always be the first thing you do. The pilot light being on speak volumes, if the light is off then there’s absolutely no way the flame can start the appliance’s gas supply. You should try to put it back on, if off. To do this, you simply have to follow the detailed instructions on your boiler’s manual strictly. If after following these actions to the letter and the issue remains the same, then you’d probably need the services of an a qualified engineer. Never try to fix the issue on your own.

✓ Check the pressure. The solution to the headaches might sometimes be as simple as examining your appliance’s pressure gauge. Here, the good numbers are around 1.0 or1.5, if it happens to fall below this, then you should open the boiler’s instruction manual. You can also inspect your radiator valves for any leaks. You’d have to call in a specialist to solve the issue.

✓ Check the thermostat. Here, it’s important to note that a faulty thermostat doesn’t necessarily imply a broken boiler. It may just signify that you need to replace your thermostat. Simply check to ensure that your thermostat is turned on and temperature is at the appropriate degree.

how long does a boiler service take?

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.

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.

does landlord insurance cover boiler

First and foremost, the purpose of a landlord insurance is simple and pretty straightforward. It protects against risks associated with your rental property as well as activity. Most policies start out with building insurance as well as property owners’ liability insurance but you’re absolutely free to include several other covers. These covers can include tenant default or accidental damage, loss of rent and more depending on your needs. It’s important to note that varying types of landlord insurance provides coverage for different sorts of risks. For instance, building insurance provides coverage for the cost of repairing or rebuilding your property, while contents insurance provides coverage for contents if they’re damaged or stolen. However, the question is, does landlord insurance cover boiler? In this post, we’re going to shed more light into this to help you make informed decisions moving forward. Let’s take a look!

 

The short and simple answer to this question is yes, landlord insurance can definitely cover boiler break down! However, this is usually possible only if you select this option when you purchase your landlord insurance policy. With some boiler cover providers, you’ll have to include a home emergency cover to your landlord insurance so as to cover any form of boiler break down. Once this is done, if the boiler in your rental property starts to malfunction or stops functioning, a Gas Safe registered engineer would be sent to your premises to help out with the situation. With this, the repairing cost of your heating system would be covered by the insurance excluding any excess and up to the limit of your policy.

how does electric central heating work?

How Does Electric Central Heating Work?

An electric central heating works to provide a number of benefits for you. These benefits include the following:

lSpace Heating

• The storage heaters work during the night to store electricity which would be used to heat up the heat retaining bricks. This, in turn, will release this energy throughout the day to warm up the room.

• There are also electric radiators which works to deliver on-demand heat and as a result, economy tariffs are totally avoided. It will generate heat by itself rather than storing it and with the controls, you can easily determine the amount of heat to be released when you require it.

• There is the wet electric system options as well which comes with water filled radiators. This operates in a similar way to normal radiators, however, it makes use of electricity to heat up the water.

lWater Heating

• An electric boiler operates in a very similar manner to other boiler types, just that it makes use of electricity as its fuel. Here, the water is warmed by a heating element and the water is later moved to several radiator throughout the house by a pump. These electric boiler types earns you tariff savings as you’ll be able to heat water at night.

• Heat pumps geothermal or air source, redistributes heat instead of creating it. Heat pumps are powered by electricity and it works by absorbing heat either from the air or ground which it then channels it through a pump. This can then be incorporated in heating either water or a room.

• A dedicated immersion heater is another water heating option. Here, the heating element is positioned inside a hot water cylinder. In a similar fashion to a kettle, the element heats the nearby water. Immersion heater can act either as a backup or your main heating element.

How long does a boiler last?

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.
