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.

✓ 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.

what size electric boiler do i need?

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.

How to repair a boiler leak?

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.

How much does boiler cover cost?

To ensure your boiler is functioning efficiently and to keep your home warm, it’s important to see that your boiler is serviced on a regular basis by a licensed boiler engineer. Failure to do this can result in sudden boiler breakdown which can be a hard hitting blow to one’s financial power especially when there’s no boiler cover to cushion the blow or totally avoid it all together.

When your boiler is covered, it implies that you’re protected in the event whereby your boiler or it’s controls malfunctions or break. Several boiler cover will include the servicing cost, while some may not so it’s advisable to always go through the details, no matter how small, before entering into a boiler cover agreement. Typically, a boiler cover will cost between £60 to £100 per year and the payment is made on a monthly basis. Various boiler insurance companies have varying cover cost, however, here are the common boiler cover policies:

• Homeserve charges from £13 per month

• EDF Energy costs from £13.29 per month

• British Gas from £12 per month

• Scottish Power from £13.13 every month

• CETRI UK charges from £13.50 every month

• 24/7 home rescue costs from £9.60 every month

• Gorgi Home Plan costs from £6 per month plus 3 months free

• Your repair charges from £9.60 per month

• NPower Boiler Cover costs from £10.92 every month

• SSE Boiler Breakdown Cover charges from £4.95 every month

It’s important to note that sometimes you have the option of adding your boiler cover to your existing home insurance, if you do not want a standalone policy for your boiler cover. In many scenarios, this is referred to as an extra or add on service referred to as “Home Emergency Cover. When compared to the standalone boiler policies, this is usually a lot cheaper as it comes in around £5 per month.

Do I need to use an OFTEC certified installer?

The Oil Firing Technical Association or OFTEC operate a competent persons scheme to certify installers. It’s always recommended to use an installer with this certification as it proves they have the training and expertise to properly install your boiler and give you realistic advice on the efficiency of your system. Also, OFTEC registered installers offer Workmanship Warranties to protect you if there are any problems after installation.
