What type of Central Heating System do you need?

Here is a handy guide to the type of system  you may already have, or which may be a better replacement for the system you are currently using. EJ Wheldon are your local Professional Gas Safe Engineers. Look no further, if you seek a Central Heating Boiler in Northampton.

Combination or ‘Combi Boiler’

These are the most popular type of boiler in the UK, as they can be extremely economical, only heating the water you need ‘on demand’.Pro’s:Unlimited hot water ‘on tap’ as it heats the water straight from the mains and saves space as you don’t need a cold water tank or hot water cylinder, which makes it perfect for smaller houses or flats.Usually, this type of system is quicker to install because there are fewer boiler parts compared to other heating systems.Con’s:Using more than one tap at a time can reduce the flow of hot water, though this also depends on the strength of your mains water pressure. Water can take a few seconds to heat up.

Conventional Boiler

Often referred to as conventional, regular or heat-only boilers. These work by sending hot water to your radiators and a hot water cylinder.Pro’s:You can use lots of taps at the same time, without the flow of water getting weaker. You can have an electrical immersion heater fitted to your hot water cylinder to give you back up, just in case your boiler ever breaks down. These systems are great for larger homes with multiple bathrooms.Con’s:You need space for a hot water cylinder and cold water tank, which is usually placed in the loft. You need to plan when you want hot water, programming your boiler to heat the water in the cylinder. You only have as much hot water, as the cylinder can hold, so if it runs out, you will need to wait until it heats up again.

System Boiler

System boilers are often known as sealed system boilers. Like traditional boilers, they have water cylinders. However, they do not have cold water tanks. System boilers are typically set up in bigger residential or commercial properties.


System boilers can provide hot water to several taps all at once and use up less space than traditional boilers. This is because they do not have a cold water tank. System boilers work with solar water heating systems. This is due to the fact that they have hot water tanks.


System boilers only heat water ahead of time and the hot water they produce can run out. The hot water tank can only hold a certain amount of water. System boilers take up more space than combi boilers
