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.

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 size of boiler you need will depend on the size of your home, how many radiators and bathrooms you have and how many people live there. 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. Other boiler types such as system boilers or conventional boilers may be better suited to larger homes because they have bigger outputs.

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.

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.

Are Electric Radiators Expensive To Run?

Just like many home additions, the running costs of electric radiators varies largely on a number of factors. Great number of electric radiators typically comes with an in built thermostat which is designed to turn itself off automatically when not in use in order to save energy.

However the energy provider’s set electricity charge tariff will also have a great influence on an electric radiator’s running cost. Let’s take a look at the running costs of an electric radiator!

A 600 Watt electric radiator ( on a standard electricity tariff) will usually have a running cost ranging between 4 to 6 pence each hour. However you should also take note that this scenario might change in situations whereby the electric radiator is not calling for heat the full 60 minutes of each hour. And this is more likely to be the situation as the thermostat is programmed in such a way that enables it to turn itself off immediately there’s an achievement of your required room temperature level - usually within 10 minutes from the time it was switched on. As a result of this, the running cost per hour of electric radiators will be greatly reduced to just about 1 to 2 pence.

It’s also important to note that enhancing the insulation of your home can go a long way to add to the heat retention value of each room. Consequently, the duration at which the electric radiator calls more heating will be significantly reduced, which in turn, implies a lower electricity bill.

Another key factor that can play a huge role in saving on your heating bills is the programming as well as usage of your electric radiators. Every radiator comes with an independent digital thermostat with a number of 24/7 programming options to help achieve maximum efficiency. When the radiator is properly set according to your lifestyle, you can save as much as 50 percent on your heating bills.

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:

• Switch off your boiler and let it cool completely

• Make sure both ends of your filling loop are attached

• Open both valves to allow cold water into the system – you’ll hear it start to move

• Look out for your pressure gauge to show 1.5 bar

• Close both valves

• Switch your boiler back on

• Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!

What Size Of Electric Boiler Do I Need?

If you’re thinking about installing central heating in your home or property, you’ll be shocked by the plethora of options that’s currently available in the market as regards the boiler type that can be installed. Being a very good alternative to gas boilers or an oil or LPG boiler, electric boilers are here to stay. They usually feature different power outputs which tends to lead to one of the most frequently asked questions about electric heaters - what size of electric boiler do I need? Here, we’ll give you a good insight into sizes of electric boilers available to help you make the right decision.

The importance of getting the perfect size of electric boiler for your home can not be over-emphasized. If your electric boiler size is too small, it won’t be able to provide the level of heat and hot water required. And on the other hand, if it’s too big, it’ll definitely consume more electricity which would be a total waste of money.

To determine the correct size, if you have a wet central heating or water radiators in your home, you’ll need to calculate the boiler’s capacity required to operate them and allow 1.5kw per radiator. To be more accurate, it’s advisable to talk to a professional installer to avoid making a costly mistake. Every professional installer should have an idea of the appropriate size of electric boiler that’ll be needed given your special requirements and home size.

Generally, with a 12k kilowatt boiler, you should be able to operate up to 7 to 8 radiators which is good for smaller properties. For apartments and flats, getting a smaller electric boiler would be the best option.
