How Should I Decide on Boiler Size

One of the things to consider when renovating a home is how it will keep you warm during the winter months. In this case, you may have decided to use a gas boiler as your central heating.

There are several operations to complete during the installation of a boiler, one of them is the choosing of a boiler type. Because of their efficiency, many homeowners favor combi boilers over other styles. Why not make your life easier by going for a combi boiler? They are now the most popular type of boiler in UK homes.

Combi boilers have practically become a necessity due to their comfort, either for heating only or heating and hot water. The many brands, types, and powers of boilers can make us hesitate when choosing the most appropriate.

Even without storage tanks, these boilers may offer instant hot water. Combi boilers are ideal for buildings with limited space because of their self-sufficiency. This post will present numerous aspects for individuals who are confused about which size combi boiler to purchase.

Why is Combi Size Important?

As well as keeping your home comfortable to live in, the ideal combination boiler should keep your energy bills as low as possible. Your energy and gas prices will unnecessarily rise if you select a combination boiler that is too large for your home. As a result, it is crucial to ensure your combination boiler has the appropriate power output and capacity.

Another factor to consider is the boiler's rated power, which is measured in kilowatts (kW) Your house will become cold and uncomfortable if you choose a combi boiler with a low power rating. Conversely, installing a boiler with a rating that is too high will waste fuel and increase energy costs. Having the correct combi boiler variant requires consideration of these two variables.

Combi boilers are typically more extensive than standard and system boilers as they provide hot water for both heating and residential use. Due to this feature, these boilers have two outputs, domestic hot water output (DHW), and central heating output (CH).

How to Determine the Ideal Size of a Combi Boiler

Counting the number of radiators in your home is one method for determining the appropriate boiler size for you and your home. Because of the increasing amount of power required to heat the entire house, the larger the boiler you'll need the more radiators you have.

Using the number of radiators on your property as a guide, you can determine the right combination boiler for you. Here is a combi boiler sizing guide you can follow:

For housing up to 100 m2, a very powerful boiler is not needed; any model with a heating power of at least 15 kW will be enough to heat the house. If the house has more than 100 m2, the power must be increased to approximately 25 kW. If the surface is 200 m2, the heating power should be close to 30 kW.

Identify the Type of Boiler You Need

Condensing gas boilers come in two different varieties: boilers that provide heating and mixed boilers that provide heating and hot water. You must first determine your needs to select the best model.

Boilers for heating that solely use natural gas, as their name implies, only provide hot water for radiators or underfloor heating. We advise that you consult an installation or professional to determine which boiler is most appropriate if they have underfloor heating since the boiler must operate at low temperatures.

A typical shower requires roughly 8 liters of water flow per minute, whereas an ordinary tap uses 4 liters. The usual flow rate of a 24 kW hot water boiler is 12 liters per minute. So, assuming there is no flow restriction, a 24 kW household hot water boiler would just about cover the simultaneous usage of a shower and a tap
