Why Replace Your Boiler?

Go greener and future-proof your home with a natural gas boiler.

There are many benefits to replacing your old inefficient heating system with a new natural gas boiler. Swipe to find out more…

Constant Supply

By installing a natural gas heating system, you don’t have to worry about running out of fuel. With a constant supply of gas, you will always have access to heat and hot water.

Increased Efficiency

As boilers age, their running costs increase. A boiler that is 15 years old usually operates at only 60% efficiency. On the other hand, a new Grade A natural gas boiler that is highly efficient can achieve over 90% efficiency. This means that you can heat your home with less energy, reducing your energy bills and saving you money.

Future-Proof Your Home

Refresh NI is an accredited installer of Worcester Bosch boilers that can operate on a blend of 20% hydrogen and 80% natural gas. This means that if hydrogen is gradually introduced to the natural gas supply, your new boiler will be compatible and ready to use.

Kinder To The Environment

By upgrading to a modern natural gas boiler, you can decrease your carbon emissions by approximately 50% compared to using oil. This is due to the fact that less fuel is required to produce the same amount of heat.

Gas Boiler Replacement FAQ's

How Do I Know If My Boiler Needs Replaced?

If you take good care of it, a typical boiler can last up to 15 years. However, it’s important to be aware of signs that your home heating system may not be functioning properly.

Warning signs to be aware of include:

1. Radiators are taking longer than usual to heat up.
2. There appears to be a leak in the boiler.
3. The boiler is emitting new, continuous, and unfamiliar sounds.
4. A foul odor is coming from the boiler.
5. Energy bills are steadily increasing.

It’s important to note that as your boiler ages, it becomes less efficient and uses more energy, resulting in higher energy bills.

Are Gas Boilers Safe?

Yes. However, it is vitally important to have your boiler replaced and serviced by a Gas Safe Registered Engineer. All Refresh NI gas engineers are Gas Safe Registered.

If left unchecked gas boilers can result in carbon monoxide poisoning, fires, and even explosions. Therefore, it is important to service your boiler on an annual basis.
