It can be bewildering to having to choose from a multitude of gas boiler models. Believe it or not, a small number of them are suitable for any home. However, it’s best to talk to an experienced heating engineer to make a decision about which one is best for your home. Of course, picking an engineer to advise and complete the installation is one of the more important things you can do.

Boilers are separated along four lines

1 – Brand
2 – System, regular and combination
3 – Condensing or non-condensing
4 – Output stated in KWs

Choosing-the-best-boilers

How Do You Pick A Boiler Brand

There are several companies that have produced worthwhile boilers including but not limited to:

- Baxi
- Ideal Standard
- Keston
- Potterton
- Valliant
- Vokera
- Worcester-Bosch

Every one of the above companies has a long history with good reputations. Of course, some of them have been bought and sold, which means some companies are owned by others. Be sure you compare them by their products, prices and the company’s after-sales care.

Look At The Manufacturer’s Warranty

A reputable manufacturer’s boiler should last beyond 10 years. Thus, it’s a good idea to look beyond price to find the best possible boiler:

- Standard two-year warranty; some manufacturer’s offer a five-year warranty
- Check out what the warranty covers
- Does warranty cover the labor and parts cost
- Is there a team of engineers to deal with the problem
- How long is the wait time for repair

Three Different Kinds of Boiler and Efficiency

There are at least three kinds of boilers and they can be either less efficiency non-condensing and high efficiency condensing boilers.

Now, larger homes should have system and regular boilers, which allows people to use hot water at the same time or for homes where there is low water pressure. A system boiler is easy to install and typically cheaper.

Combi boilers are better for small homes where there’s just one bathroom; these are also cheap to install and run effectively.

A Look at Regular Boilers

Regular boilers generate hot water that’s stored in a cylinder. Conventional heating systems tend to have gravity-fed hot water from a tank. However, if the boiler must be replaced, the system will need to be changed so it’s fully pumped. There are several boilers that are called Back Boiler Units, which are placed in behind a fire. As it stands, Baxi is currently the one manufacturer of the condensing back boiler.

A Look At System Boilers

The hot water and heating are pumped into a sealed system, which will also store hot water in a pressurized water cylinder. This kind of heating system has a real advantage over regular boilers because it’s easier to install because more parts are found in the boiler and no reason for a tank.

A Look At Combination Boilers

The boiler heats the water when it comes from the tap and there’s no cylinder for the hot water.

Boiler Size: What Should You Use

When considering what size boiler to get, people often look at the physical space it’ll take up. However, the dimensions don’t reflect the boiler’s actual output. Some are washing machine size and can be hung on the wall or placed on the floor. Many of the boilers are smaller.

Boiler size is gauged in output. Bigger does not mean better. Output needs to be calculated for the construction of the home, its size and number of rooms. If a boiler is too big, the system won’t work right. The hired heating engineer will determine what the required boiler output is.
