New System Boiler Replacement

Replacing your system boiler has never been easier. Don’t be fooled by the simplicity of being able to choose your boiler online and book a Gas Safe registered installer to come out and fit your new system boiler. It really is that simple. As you can see from the boiler comparison price list you can choose from all the main brands such as Worcester BoschViessmannIdealBaxiVokeraAlpha Heat Line. All the prices for boilers on this page are combi boilers. If your looking for combi boilers try here. If your looking for regular boilers, try here.

Installing The Right New System Boiler For Your Home

Choosing the right type of boiler for your home is the most important thing to do, for example do you need a combi boiler, a system boiler or a regular boiler. The second most important thing is to get the right sized boiler for your home. This is the KWh number you see new to the new boilers. The bigger your home, the higher the number usually needs to be. This is so that the boiler can cope with the hot water demand in your home. If you have more radiators or more than one bathroom then you will need to make sure that the boiler is powerful enough to pump water around the central heating system at the right temperature. When you complete the online surveys from the best boiler installation companies such as Heatable, Boxt & Warmzilla, then the boilers that they say will be suitable for your home will appear on the results page. This is why you must ensure that the information you provide is absolutely correct. 

Choosing The Right Boiler Installers

Choosing between our recommended boiler installers, Heatable, Boxt & Warmzilla is easy really. They are all rated excellent on TrustPilot and all used the same model of using local Gas Safe registered engineers who are authorised to install boilers by themselves. All of the companies offer their fixed online price no matter what. All costs are covered as long as you have provided them with the correct information beforehand. The only real difference will be the price and the boilers each company offer. If you are unsure don’t hesitate to contact each of them prior for your peace of mind. There really aren’t any tricks or hidden costs!. 

Getting The Right Price For Your New Boiler

If you choose to use one of our recommended installers you will provide them initially with basic information about your current boiler to get the correct fixed price. You will be asked what fuel your current boiler uses, such as gas, oil, LPG. Most people have a gas boiler. You will be then asked what type of boiler you have. Do you have a combi boiler, system boiler, regular boiler or back boiler? You will then be asked if you want to change your boiler or keep it the same. The next question will be about where you want your new boiler. Do you want it in the same place or do you want to move it somewhere else? You can move a combi boiler, system boiler or regular boiler. You can no longer have another back boiler installed. You must install a new type of boiler and pay for the conversion. Any extra work such as moving a boiler or changing boiler type will incur extra costs but will be included in the price as long as you choose this option.
