How To Fix A Boiler

A boiler is subjected to regular usage, working for a several hours a day and providing hot water for shower on a daily basis and even more so during winter. With it’s power and efficiency, we tend to postpone or even totally overlook its maintenance. However, no matter how good your boiler is, it consists of many moving components and it’ll certainly develop some faults some day. When the inevitable occurs, you might want to save some money and get it fixed all by yourself.

When it comes to fixing boilers, seeking help from a licensed heating engineer is usually the best solution, however at times you might be just lucky to be faced with minor issues which you should be able to handle yourself. In this article, we’ll look at some of the most common causes of a broken boiler and how you can get your heating system up and running again. Let’s have a look!

✓ Low system pressure. In the event whereby your boiler display a low system pressure, it could mean that the system is about to breakdown. You’ll have to carry out regular inspections on the pressure gauge to see if there’s any noticeable changes and call in a heating engineer immediately to prevent a system breakdown from happening.

✓ Poor heat production. Although this is unlikely to lead to any great issues, but it’ll reduce the effective functioning of your heating system. To prevent a debris build, it’s important to have your boiler cleaned regularly.

✓ Strange noises. Boilers often make noises, so there’s nothing to worry about unless it’s a banging or whistling noise that’s very odd , then there may be a serious issue. You’ll have to check the air intake, pressure, exhaust and piping to ensure they’re working just fine, if not there may be a need for replacement.

Ad hoc visits from your engineer to fix small issues with your heating system may actually seem cheaper and a lot more affordable, however when a boiler is ripe enough for a change these small issues are always never ending. Over some period of time, these small issues will inevitably get worse and the idea of “mend and make do will be an absolutely false economy. The best course of action in this sort of event is to find a replacement boiler to install as soon as possible. In this article, we’re going to give you some hints that’ll show you when your boiler needs to be replaced. Now let’s take a look!

✓ Insufficient hot water. Here, you’ll have to check the size of your hot water cylinder. It’s crucial to make sure that your boiler is rightly sized to power your heating as well as hot water circuit in line with your demands. You should always seek the advice of a heating expert who can recommend whether to fix or replace the boiler.

✓ Strange noises. It’s normal for components of the boiler to become worn or damaged over time. Replacing the particular component that’s causing the knocking or rattling may seem cost effective at first but more often than not, the noises usually signal a bigger issue which is likely to build up over time. Hence, it’ll be a lot more logical to replace the boiler itself.

✓ Regular repair of your boiler. It’s essential to have your heating system serviced by a Gas Safe engineer on an annual basis. However, when you have to call them more often than once a year for your yearly maintenance, it may be a wise decision to consider getting a replacement.

✓ Other events whereby you may need a new boiler includes when you can’t get the right temperature in your room, when the radiators don’t heat up as they should, when your boiler leaks and if your boiler still has a pilot light.

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.

The simple answer to this question is yes. The Google Nest thermostats are built in such way that makes it compatible with most 24V systems including the older systems. The device is functional with all common types of fuel such as electricity,natural gas as well as oil. However, before purchase it is vital to determine if your thermostat is also compatible. What’s more? The Nest thermostats is also designed to be usable even without the existence of a C wire (common wire) in your home, although a new C wire installation may be required.

Furthermore, Nest Learning Thermostat is compatible with multiple central heating system such as combi boiler systems, air source and ground source heat pumps (heating only) as well as heat only boiler. Now let’s take a look at the Nest thermostat compatibility!

• The majority of the 24 V systems ( including older systems) are compatible with Google Nest thermostat. They can be incorporated with each and every common types of fuel such as oil, natural gas as well as electricity.

• Prior to the installation of Google Nest thermostat, you can make use of the Google Home or Nest app for proper guidance and to notify you if your system is compatible. It will also give you a bespoke thermostat wiring guide.

• To check the compatibility of your system, you can also check with the Google’s online compatibility checker before purchase.

Modern oil boilers do not require a lot of maintenance. OFTEC recommends that oil boilers are serviced and inspected every year. This keeps them running as efficiently as possible and will ensure any issues with your boiler are identified before they cause bigger problems. This servicing is also vital because of the increased risk of carbon monoxide leaking from a poorly maintained boiler.

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.

Can You Get Oiled Fired Combi Boilers?

Absolutely! Oil fired combi boilers are not only a super cool alternative to gas heating, but also offer a cost-efficient means of heating your home. And this is best enjoyed especially if you’re one of the estimated 4 million houses that are not connected to the gas network.

Oil fired combi boiler enables you store fuel close to your property and fill it as required. There many A rated model options available in the market with the modern oil fired combi boilers confirmed to be up to 95% efficient. As a result of their multiple advantages over alternative heating systems, the oil fired combi boiler is expected to increase significantly in the UK. Here are some of the advantages of adding the system to your property.

• Oil fired combi boiler heats up water on demand while also saving a lot of fuel and being super energy efficient.

• Since oil needs more fuel than gas, a great return would be derived from every unit of energy.

• When compared with the other types of boilers, oil fired combi boilers have a considerably lower operating cost.

• A new oil fired boiler typically has a 92% to 95 % efficiency, which is significantly better than the 60% to 70% in older systems.

If you have an idea of how to operate the gas-powered alternative, then operating an oil fired combi boiler shouldn’t be an issue. In a similar way to the alternative, the boiler simply delivers the central heating through the radiators and hot water via your household’s taps.

However, the major difference between the two is the fact that the oil fired boiler needs a regular supply of oil, which is stored in a tank. The hot water supplied by the system is instant as it is connected to the water mains supply.

If your boiler is leaking, there are some checks that you can do yourself. However, you should never attempt to repair your boiler yourself – only a Gas Safe-registered engineer should conduct repairs.

There are 3 main reasons why your boiler might be leaking: there’s a pressure valve fault, a temperature valve leak or corrosion in the system. An engineer will be able to spot the problem quickly, but in the meantime there are a few things you can do:

Check the pipe fittings

If your boiler is leaking water around the pipe fittings, it could be an installation fault and you should get in touch with the engineer that fitted it. You can check the pipe fittings by drying the area then waiting to see if the water appears again. If it does, you may be able to do a ¼ turn of the pipe to stop it. However, you should still call the engineer that installed it to ask them to check the PTFE tape on the inside.

Inspect the seals

Over time, the rubber seals on a boiler can start to perish, so if you have an old boiler this could be the source of your leak. If you have a new boiler, it could be caused by your boiler running over pressure.

Heat exchanger corrosion

Unfortunately, if a boiler engineer discovers that the boiler is leaking water from the heat exchanger, this is the end of the road for your system. The heat exchanger is the most expensive part of your boiler, so it makes more financial sense to replace your boiler with a newer, more efficient model rather than try to replace it.
