Conventional boilers (sometimes known as regular or heat only boilers) require a hot water cylinder and a cold water tank. They are best suited to households where multiple people will be using hot water at the same time. Conventional boilers are also suitable for older homes where they heating system hasn’t been recently upgraded.
Advantages Of A Conventional Boiler
- Backup Hot Water – An immersion heater can be installed in the hot water cylinder. This means that if your boiler breaks down you can still generate hot water.
- Multiple Users – Hot water comes from the hot water cylinder. This means that multiple taps or showers in the house can distribute hot water, at the same time, without any effect on the temperature or pressure of the water.
- Works With An Old Heating System – Conventional boilers can be the best option for an older property with an old heating system. This is as it only requires small or no changes at all to pipework.
- Solar Panels – Conventional boiler systems are compatible with solar thermal panels.
Disadvantages Of A Conventional Boiler
- Space – Conventional boilers can take up a lot of space in your home. You need a loft to house the cold water tank and an airing cupboard to put the hot water cylinder. This is not ideal for smaller homes or flats.
- Hot Water Isn’t Instant – Once all the hot water from your cylinder has been used you will need to wait for the tank to heat up again before you can use it.
- Heat Loss – The hot water stored in the cylinder can loose heat over team, which is not very efficient. To prevent this you should ensure your cylinder is well insulated.
- Complicated – Conventional boiler systems can be complicated and costly to install. This is because of all the different parts and the pipework, which can be time consuming to install.
