  3. If your boiler is past the point where it's inexpensive to fix it. If you've called out a trained heating engineer to check out your boiler and also they've told you that it  goes to the moment of truth after that it's time to invest in a boiler replacement.
  4. If you intend to sell your home or you're restoring your house, a brand-new boiler can contribute to its value.

In some situation, you may be able to escape just putting in new controls.
  6. If your boiler is G-rated for energy performance it's a great concept to change it.

    FAQs

    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.

    how long does a gas boiler last?

    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.

    Can I stay at home while my gas boiler is being replaced?

    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!

    What size boiler do I need?

    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.
