What types of boilers are there?
Firstly, there are three main boilers available on the market for domestic properties; Combi boilers, Conventional boilers and System boilers. Here are those boilers explained:
A combination boiler, more affectionately known as a combi boiler, combines both a high efficiency water heater and a central heating boiler in one. They tend to be more compact because they don’t need a hot water cylinder.
A conventional boiler, also known as a traditional boiler, operates your central heating system through a separate water cylinder or boiler where gallons of water can be heated, stored and readily used.
A system boiler is like a conventional boiler, but they take their water supply directly from the mains. They often take up less space as they don’t require a tank.
What boiler is right for me?
So, you’ve read about the three boilers available, but what is best boiler replacement for you and your home? This is where house size, radiators and the number of bathrooms and people in your house come into effect…
The number of people living in your house:
This plays a significant part in boiler choice because if you opt for a boiler that’s too small, you’ll soon discover that your home isn’t adequately heated. It also won’t be supplied with enough hot water to meet your demands. On the other hand if you choose a boiler that’s too big you’re likely to produce more energy than you need, which will increase your bills and generate unnecessary emissions.
So, what boiler do small families need?
Smaller households are likely to use less heating and hot water and so are likely to be better off with a combi boiler.
And what boiler do large families need?
Large families are likely to use lots of hot water, so a conventional or system boiler might be more appropriate.
The number of bathrooms in your house:
If your home has many bathrooms that are used at the same time you’ll have high demand for hot water. Not to mention all the bathroom radiators that will have to be heated. Choosing the wrong boiler can cause a decline in water pressure – not ideal when the whole family is getting ready to head out!
So, what boiler do homes with multiple bathrooms need?
Combi boilers are great for smaller homes with relatively few bathrooms – from flats to houses with single bathrooms. Having said that, a decline in water pressure can still be felt if more than one appliance is using the combi boiler at the same time.
And what boiler do homes with multiple bathrooms need?
A conventional or system boiler might be more appropriate for large houses where bathroom radiators are turned on and showers are used at the same time.
The amount of free space in your home, for example the loft or airing cupboard:
If you have a large home and family with adequate space for a storage tank to supply hot water, then a conventional boiler will be good for you. With a conventional boiler your water is heated via heat exchangers, so you’ll be provided with gallons of hot water at the ready.
But what if you have a large family and don’t have the space for a storage tank? If that’s the case then a system boiler will be the best boiler for you. A system boiler works like a conventional boiler; however, they have major heating and hot water components built into the actual boiler, removing the need for a tank. You’ll need a cylinder for storing your hot water, but you won’t need to find space for a cumbersome tank. System boilers are also quicker and easier to install than a conventional boiler.
Number of radiators
The higher the kilowattage of your boiler, the better your water flow rate will be. If you want to go for a combi boiler, the number of radiators you have will help decide on the right wattage of your combi boiler to help provide you with good heating and water pressure.
- Less than 10 radiators = 24 to 27kw combi boiler
- 10 – 15 radiators = 28-34kw combi boiler
- 15 plus = A 35kw and a 42kw combi boiler
Is it good to have an efficient boiler?
Heating accounts for over half of your yearly energy bills. So whether you’re looking to reduce your bills or your carbon footprint, efficiency is key. And with the right boiler choice you can reduce your carbon footprint and your bills.
Modern boilers are condensing boilers, ensuring as much heat as possible is converted into useful heat for your home, meaning your fuel can go further. Of course there are many ways of reducing your heating bills, such as turning the thermostat down a degree and installing heating timers. But according to the Energy Saving Trust, switching from a G-rated boiler to a top of the range, modern A-rated boiler can save you up to £200 a year!
I’m not connected to the UK’s gas network
Most homes have a gas boiler and a gas heating system and are connected to the UK’s gas network, but not all homes. If you’re not connected then an oil-powered central heating system will be a great alternative to a combi, system or conventional boiler.
