If your old boiler broke down recently and has reached its maximum lifespan, there is no getting around the fact that you have to buy a replacement. When you shop for new boilers nowadays, you might be surprised to know that the model you have at home is quite behind since technology has leaped onto new boundaries since. The key is to find the cheapest boiler that will make your money’s worth.
Before deciding on a boiler model, you have to choose whether you will like a combination boiler or you prefer a boiler system. Combination boilers are the most popular boiler type in all of United Kingdom because it is not only compact but also easier to install. This has the capacity to heat the radiators as well as the running water regardless of the household’s demand. This does not require a water storage which is suitable for properties with limited space.
Another type of boiler is the system boiler which is more suitable for those who want to have a storage cylinder for hot water. This enables the entire household to use hot water from different outlets at the same time. If you have enough space in your home, this is recommended because the installation is neater, quicker and cheaper.
The third type is the regular boiler also known as the conventional boiler. This is mostly used by homes that are designed with a heating system that opens like a vent. This is somewhat similar to a system boiler because it needs a hot water cylinder in order to store water. The disadvantage is that the system is more expensive, it requires a lot of pipework and components and the space needed is also much bigger.
The three types have been laid out already but the question now is the size of the boiler. The age-old rule of thumb which requires the boiler to be bigger by 30 per cent no longer applies. You can ask more help from a professional boiler installer or you can calculate based on the size of the house, the heat loss and the materials used for insulating the house.
