• Regular Servicing Of Your Oil Boiler

Getting your boiler serviced by a manufacturer approved engineer on an annual basis is one of the easiest and quickest ways to ensure that your oil boiler is operating at its maximum efficiency level. When a full servicing is provided for your oil boiler, checks are made to ensure that all components are functioning the way they should while also identifying the bad or worn parts that may be hindering your oil boiler from functioning in an effective manner. As a result, it helps you see to the fact that your boiler is not consuming more than necessary to make sure your oil boiler lasts longer.

• Set Your Thermostats Correctly

When you set your room thermostats and thermostatic radiator valves (TRVs) the right way, you’ll be sure to get a comfortable home without having to make use of much fuel.

• Consider Smart Technology

If you decide to make use of smart technology like Nest or Hive, you can save more money when compared to their more conventional counterparts. These smart technologies incorporate highly advance intelligent systems to get more familiar with your lifestyle, habits as well as heating operations in order to ensure optimum efficiency at all times.

• Put Your Radiators To Good Use

what is a combi boiler?

A combination boiler, also referred to as a “combi boiler, delivers both domestic hot water and space heating in a single package so as to save space, and in a lot of cases, money. These great features makes the appliance a very popular choice in UK homes and in fact, it represents more than 50 percent of all new boilers fitted in the UK on a yearly basis.

Most modern and high efficiency combi boilers are usually stainless steel condensing boilers which normally features an in-built secondary heat exchanger to deliver domestic hot water to a home or property. What’s more? When it comes to the heating season or the cold months, the combi boiler will operated as required to heat a structure and offer hot water for showers, sinks as well as other hot water appliances around the house. And when it gets to the warm season or summer months, the combi boiler will only work when there’s a need for domestic hot water which also helps you save more money.

Combi boilers are able to provide domestic hot water in such a way that’s energy efficient due to two primary reasons - the combi units possess a very high operating efficiency and also have a low internal water volume. As a result, in during the hot summer when space heating is not required, you’ll only have to pay to heat up the hot water that you really need and not an entire tank.

Combi boilers also have the following benefits:

✓ Lower costs. Due to the combined nature of the boiler and the lack of tank in the roof space, the installation time and costs are at a minimum.

✓ Saves space in your home as it effectively combines a central heating boiler with a water heater into one unit.

do i need a new boiler?

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.

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.

do british gas service oil boilers?

Do British Gas Service Oil Boilers?

Are you interested in finding out whether or not the British Gas service oil boilers? Well, you’ll find the answer in this article! The British Gas engineers are able to repair several types of boilers such as home based combi, conventional as well as system boilers.

For a yearly boiler service British Gas engineers will provide the following solutions to ensure central heating and boiler are both in proper working condition and also absolutely safe.

• Inspection of your boiler for possible leaks and corrosion.

• Detach your boiler casing to ascertain the proper functioning of it’s main components.

• Clean up all parts as necessary

• Attach the casing back to the system and make sure its well sealed

In some cases, British Gas engineers may be able to complete the entire boiler service in one visit. However, it all depends on the problem that’s discovered (if any). They may not possess the required part to fix the problem with them, so they’ll have to order it from the British Gas national distribution centre. Most times, this part will get to them the next day so they can finish their tasks as soon as possible.
