Things you need to know before installing a new boiler.
If your boiler is more than 10+ years old, it may be time to replace it. According to the Energy Savings Trust, about 55% of a home's energy bills are for heating and hot water. But the good news is, Installing a new boiler can save you money on your energy bills and improve your comfort level. Before you purchase a new boiler, you should take into consideration a few things. Think about the boiler type, brand, manufacturer and the Kw rating, which is dependent on the family size, number of rooms, bathrooms and radiators.
If you're unsure where to start and need more information on the choice of boiler, check the complete guide below, then call serviceteam.
What type of boiler is needed?
The boiler you need will depend on your home's energy needs (as above). There are three basic types of boilers - a combi, conventional or system boiler. Before arranging for an installation make sure your property has been thoroughly surveyed by a heating engineer prior to the installation. The heating engineer will ask questions related to family size, consumption needs etc., to ensure the size of the boiler is compatible with your family needs.
Conventional boilers
This type of boiler is an excellent choice for those who need access to hot water quickly. They're relatively low-cost and easy to install. They will have a water storage tank and a hot water cylinder.
System boiler
System boilers are a great way to provide hot water directly from the cylinder for bathing and heating. A system boiler has no need for a central heating expansion tank, so a little saving on space (not much).
Combi boiler
The combi boiler is popular in the U.K. requiring the installation of one component, the boiler. Making it easy and quick to install. It's great for smaller homes, flats and apartments as they don't take up much space. As there is no hot water storage cylinder, you can free up more space. However, if the boiler breaks down, you will not have a facility to store hot water until the boiler is fixed.
What type of fuel does a boiler use?
Boilers can use various fuel sources. The most common fuel source is natural gas, followed by oil. However, some boilers can also use coal, wood or solar power as an energy source. For example, some homeowners may prefer an inexpensive fuel, while others may prefer a more environmentally friendly fuel.
Let’s not forget that an average UK gas boiler emits more CO2 emissions (per annum) than seven transatlantic flights, according to the charity NESTA. So, it is better to use sustainable fuel to reduce our carbon footprint.
What is the best boiler brand?
When you search for a boiler, make sure the boiler is a trusted brand. The more reliable the brand, the fewer unexpected breakdowns. We know you want a boiler that will stand you in good stead for the years ahead; therefore, do your research. WHICH Magazine is a good place to start, and Google reviews are another. Research all the boiler brands before making a decision. Maybe, a family friend or relative has a boiler that’s given them years of trouble-free service; that’s a good recommendation?
Remember, a cheap boiler may not always be the best buy. Investigate the after-sales support and the length of warranty/guarantee. A reputable boiler manufacturer may offer as much as a 7-10 years warranty on some makes of their boilers (subject to conditions).
What size boiler is needed?
A qualified heating engineer will advise you. They will consider the family size and needs, the number of bathrooms, and the number of radiators. If a boiler Kw rating is insufficient to cater to the family's needs, you may run out of hot water when everyone is getting ready for school or work - not ideal!
Hot water on demand?
If you want hot water on demand, i.e., the moment you turn on the hot water tap, then a combi boiler is an answer. Also, if your water supply is metered, you won’t be wasting water waiting for it to warm, as is the case with a system or regular boiler.
Generally, conventional boilers are better suited for high family demand, whereas combi ones can handle lower consumption rates efficiently.
How much space is available?
No room in the loft for a tank or in the airing cupboard? Then a combi boiler would be the answer! They don't require hot water cylinders or a storage tank (in the loft), which means more space for storage or a loft conversion, maybe?
Where do you want to install the new boiler?
In the kitchen, utility room, under the stairs, or outside in the garage? If the new boiler is to be repositioned, then extra pipework, fittings etc., will be required as well as ensuring adequate ventilation to an outside wall.
If you’re unsure if the new boiler can be repositioned, our heating engineer will advise you.
How much does it cost to install a new boiler?
The installation cost depends on several factors, i.e., Kw boiler size, its location and any extras required such as a Magnaclean, isolation valves, powerflush etc. The bigger the boiler in Kw ratings the more expensive the unit.
If it’s straight, like for like, swap, then replacing the old boiler with a newer model can cost in the region of £2,000 -£3,000. If a boiler upgrade is required that raises the Kw rating; then it will cost more.
Make sure the boiler comes with a warranty.
Whilst the boiler is a high-end investment, It is, therefore, important to investigate the length of the warranty before purchase. You should enquire if your new boiler includes parts and labour and ask what is not covered under warranty to avoid any surprises!
