Deciding which type of boiler is right for you
The type of boiler you require depends on several different factors, from how many people will be using the hot water to how many radiators are on the central heating system. Here we out line some of the key differences between the 3 main types of boilers, combi boilers, system boilers and conventional boilers. If you have any further questions get in touch with us and our team will be happy to advise you.
Combination boilers have been increasing and increasing in popularity due to their space saving design. The boiler supplies heating and hot water in one and as such do not require a water tank or a hot water cylinder. They heat water on demand, straight from the incoming cold water mains supply. Combi boilers deliver instant, unlimited hot water and are a good choice if you enjoy a long shower with good pressure and flow rate.
Without the need for hot water cylinder or cold water storage tank and that most can be installed easily within a stand kitchen cupboard and that you no longer need to heat water that you may not use combi boilers have taken the lions share of the UK boiler market in recent times.
One thing to consider before choosing a combi boiler is the lack of a back up hot water cylinder with immersion heater. If the boiler breaks down you won’t have any heating or hot water. Also, if you have a large home with several bathrooms, a combi boiler is unlikely to be able to meet your hot water requirements.
Advantages of a Combi Boiler
- Instant unlimited hot water
- Great for homes with low hot water demands
- No need hot water cylinder and no cold water tank
Disadvantages of a Combi Boiler
- Should the boiler breakdown you may not hot water or heating
- It may take longer to fill a bath tub
Like combination boilers, system boilers do not require a water tank. The central heating and hot water is provided via a sealed hot water storage cylinder, which is normally located in loft space or airing an airing cupboard. System boilers are considered the best solution for homes with more than one bathroom and a high water demand.
Most heating and hot water system components are built into the boiler itself, making it quicker and easier to install.
Advantages of a System Boiler
- Ideal if your household has a high demand for hot water
- System components within boiler
Disadvantages of a System Boiler
- The cylinder must be well insulated to prevent against heat loss and energy wastage
- They occupy more room than a combination boiler
- If you want a powerful shower you may require booster pump, accumulator or unvented cylinder
Conventional/ Regular Boilers
Conventional boilers are also known as regular or heat only boilers. They are designed to work with conventional heating and hot water systems that have a separate hot water storage cylinder, a cold water storage tank and a feed and expansion tank normally housed in the loft.
Systems with conventional boilers have most central heating components outside of the boiler.
Advantages of a Conventional Boiler
- Use several taps at the same time
- Suitable for larger properties
- Suitable with an old heating system
Disadvantages of a Conventional Boiler
- The size of the cylinder will limit the amount of hot water you can use
- Like system boilers, if the cylinder is not well insulated heat will be lost
- Most system heating components are outside the boiler taking up more space
- Most susceptible to corrosion
