Can I Repair My Own Gas Boiler?

If you’re more of an handy person, then you’d probably want to fix everything you can around the house while saving yourself some money that would have been spent on hiring a professional instead. This is a very cost effective but at the same time you must know that some tasks are usually more difficult than others, and a good example of those complex tasks is boiler repair. Not only can this be very tough, but they can also potentially be one of the most dangerous home appliances you can acquire. So with that in mind, what can be done to ensure your gas boiler is taken care of and in the event whereby it starts to malfunction, what can be done to remedy the situation?

With regular maintenance and repair of your gas boiler, you’d have absolutely nothing to worry about. However one of the fear several DIYers have is the fact that they might just end up incurring more expenses on services they didn’t really need in the first place. But when it comes to gas boilers, it’s necessary to be certified to work with them as it’s very dangerous to tackle it all by yourself. Despite this, there are still some minor issues that you wouldn’t need to hire a technician to resolve. In some cases, all that would be needed is simply to reset the boiler. To identify where the reset button is, simply go through your boiler’s manual for more information. Most times, all you’ll have to do is press down the reset button for a couple of seconds. If the boiler isn’t fully restored to its normal proper functioning state after two resets, then you may need to call in a professional for help.

In recent times, home and property owners are constantly looking for ways in which to enhance both energy efficiency and sustainability especially as the world draws closer and closer to energy-efficient technology. The Nest thermostat is a great example of this fact as its designed in such a way to save energy while also cutting heating and cooling costs. And an interesting fact is, you’re not limited to using just a single Nest thermostat in your home as multiple of the device can successfully run together to maintain a consistent level of temperature monitoring as well as energy efficiency. What’s more? You can add up to 20 Nest thermostat and 18 temperature sensors in a home.

It’s very unlikely that you’re going to need this many thermostats in your home, but if you’d like to add a second the process is quite straightforward. However, we’d recommend you employ the services of a seasoned professional especially if you lack the required training or experience to pull this off to save yourself some time and money.

To get started, simply download the associated Nest app to add Nest devices. Now let’s have a look at the processes involved in adding a second Nest thermostat to your home.

• Open the app.

• Go to the top left corner of the main screen and click on the menu button.

• Pick the location or home you’re adding the device to.

• Go to the top right corner and select the “settings.

• Once done, then click on the Add Product “Plus button.

Upon a successful addition of the second thermostat, the app will guide you through the initial set up steps. Google also offers a very helpful guide if you’re unfamiliar with the initial configuration.

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

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.

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.

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:

1. Switch off your boiler and let it cool completely
2. Make sure both ends of your filling loop are attached
3. Open both valves to allow cold water into the system – you’ll hear it start to move
4. Look out for your pressure gauge to show 1.5 bar
5. Close both valves
6. Switch your boiler back on
7. Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!

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!
