Choosing a Combi Boiler

Things to consider when having a combi boiler installed

Combi boilers are a popular type of boiler in the UK, and can be an option if you need to replace your existing one. They offer many convenient and efficient features which make them highly sought after by homeowners and landlords alike. If you want to find out more about what a combi boiler is, or why they appeal so much to people who use them, this article will explain everything you need to know.

For anyone that has owned or lived with one before, it can be hard to imagine life without a combi boiler as they're incredibly convenient and versatile. Renters may even wonder whether they should consider getting one fitted if their current unit is unreliable or inefficient.

When comparing two combi boilers from different manufacturers, the first thing to look at is how much power they produce, and this can be roughly gauged by comparing their kW ratings. The higher the number, the more power it will use in order to heat your home. It should be noted that a more powerful boiler does not necessarily mean it's going to cost you more money as some of them are designed to operate very efficiently once installed.

A combi boiler offers great value for money because they do double duty as a conventional boiler and hot water tank which both saves space and reduces energy consumption in comparison with standalone units. If you want one fitted, then there are several benefits.

The most important aspects are reliability and efficiency, if you can't rely on your boiler to work when it's needed then it's going to be a huge problem in the long run. It goes without saying that you'll also want a high quality finish so that it looks good in your home and stands up well over time.

Combi boilers are generally quieter than conventional ones. Consumers should always make sure their new system comes with an RHI (renewable heat incentive) incentive tag as these are exempt from VAT. This essentially means you get the best possible price, and will lower your running costs in comparison with other models on the market.

Finally, there's an option to have a condensing combi boiler installed; this simply means that air is removed from the system and moisture turned into water vapour before it leaves the unit. This results in less gas being wasted and lowers energy consumption even further. 

Combi boilers Should be fitted by Gas Safe Registered professionals, so make sure you only use someone who has gone through rigorous training and follows safe procedures when installing new systems or making repairs, no matter what type of boiler they're working on. 

How to choose a combi boiler?

When doing this, it's essential to consider the size of your home in order to find combi boilers providing enough hot water for you and your family. If you already know which size is best for you, both electric powered and gas-powered models offer great energy-saving features.

Another thing you need to pay attention to is power. The greater output a combination boiler has, the better it will be in heating your home and providing domestic hot water for all family members. Output is measured usually in kilowatts. The most popular combi boilers for UK homes have from 35 kW to 80 kW of output as providing up to 80% of total heat required by properties that are located in central England and are 2-4 storeys high.
