Sticking with what you know is a habit we all find difficult to break. We all find it hard to try new things sometimes, and the story is exactly the same with the boiler in your home. If you’ve settled on a boiler type or boiler brand since who knows when, then for many of us, it makes sense to trust what we know and stick with it.
For example, changing to a combi boiler from a different type of boiler can be a risk that many are afraid to take - especially if you’ve never had a different type of boiler in your home before. When sticking with the same boiler, it’s easy to know how the controls work and how to get your home to the exact right temperature by using your thermostat. However, if you’ve had your boiler for around 10 years, it’s likely that its performance will start to decline if it hasn’t already done so. As a result, you should really look to make the change to a new boiler.
Instead of opting straight for what you know, there may be much better suited boilers out there for your home; ones that can not only save you money, but those which are much kinder to the environment too. Thanks to advancements in technology, the boilers of today are much more efficient.

A combi boiler combines home heating and hot water within the same unit. This type of boiler heats water from the mains when you need it. It instantly sends heated water to your taps, showers, and radiators.
Combi boilers have a range of benefits for not only you and your home, but for the environment too. Here’s how converting to a combi-boiler system is a great move:
Now we’ve grabbed your attention with the great benefits of combi boilers, it’s good to know the process involved in converting to a combi boiler. The first thing you need to do is to find the perfect boiler for your home. Thankfully, instead of making you do a ton of research to find out what you need, we’ve created a helpful tool to do it all for you.
First, go to our ‘Find A Boiler’ tool on our website. You’ll then be presented with a series of questions which help us work out which boiler would be best suited to your home set up.

It’s important to consider the hot water flow rate. This is expressed as litres per minute (LPM) and indicates the speed at which the boiler can heat your hot water. Hot water flow rates on combi boilers can vary from 9.8LPM to 25LPM. An easy way to understand this is if you take a boiler rated at 10LPM, then it means that the boiler will heat 10 litres of water by 35 degrees every minute.
To calculate your hot water requirements, you need to count how many bathrooms you have and how often they are in use at the same time. Our selection of boilers all vary in terms of litres per minute so it’s always best practice to test your incoming cold-water pressure before deciding which combi boiler you require. You can use an online water pressure test to determine your flow rate.
Typically, a shower needs around 5LPM of hot water, whereas a bath is about 8LPM. These figures are for guidance only, as water usage varies significantly from one tap/shower to another.
When converting from a standard boiler to a combi boiler it’s likely that the water pressure in your pipework and outlets will increase. If your pipework was professionally installed and in good condition - the pressure change will not be noticeable except for water coming out of your taps faster.
However, if your pipework is in poor condition and cobbled together, then a change to a combi boiler may not be the best option for you as there will be a risk of leaks and burst pipes/fittings. If you’re swapping to a combi boiler, it’s strongly recommended that you always keep a good lookout for any leaks or damp patches around your home for a few weeks, after the work has been completed just to be sure.
You should be aware that due to the wide variety of showers available in the market place it is not possible BOXT or our engineers to determine if a shower and your boiler will be compatible.
