Winter is quickly approaching, and we know you’re eager to get your new petrol boiler installed so you can beat the cold with efficient and effective heating. How long will this take?” you enquire, nervously scanning the calendar. “As long as necessary to ensure it works to the best of its ability,” is the correct answer. That time will vary from home to home and boiler to boiler.

A new boiler installation can take anywhere from 1-3 days, depending on the complexity of the job. You should also make time for your survey appointment, which will occur before your installation. During this appointment, a surveyor will talk with you about your home and heating needs to ensure that the right boiler is chosen and installed.

Our company do two types of a survey before the actual process

For homeowners who prefer to have their survey conducted electronically, this is a quick and easy option. Simply download the survey app, and a surveyor will walk you through the survey process, examining your current system and determining your heating and hot water requirements.

In-home polling

During this appointment, a surveyor will come to your home and inspect your current heating system, including the boiler, gas meter, and bathrooms, among other things. They’ll also enquire about your heating and hot water needs.

What to assume when installing a new boiler?

We cannot give you an exact time frame for the boiler installation, but we can give you information about what to expect.

The first thing to remember is that the installation process begins before the boiler arrives at your home. Your installer needs to ensure that you have the right size boiler for your home, and to do that, perform a heat load calculation to determine your home’s heating needs.

Boilers have few mechanical parts and are the simplest of the major heating systems. Installing a boiler is generally quicker than installing a stove, heat pump, or underfloor heating (which can require extensive work on the floors of your home). When a handyman needs to replace an old boiler with a new one, the job often takes him only a few hours a day. If the water in the system needs to be drained, or if the old boiler is too lazy to remove, it slows things down.

If you already have a natural gas line running through your home, you can expect a smooth installation. However, switching from systems that use forced air through ducts (furnaces, heat pumps) is time-consuming. Boilers don’t use air but instead use heated water that is sent to endpoints in your home to radiate heat into your living space. Going to the boiler means changing the distribution of heat. 

The installation’s density

The complexity of the job and the amount of labour required will have a significant impact on the time it takes to install your new boiler, as will the cost. Here are some examples of how complicated boiler installations can be:

Same location, same swap this type of installation, also known as a like-for-like swap, entails replacing your current system with a boiler of the same type. This is the quickest type of installation because it requires the least amount of change, it may only take one day to complete.

Choosing to have your new boiler relocated within your home may slightly lengthen the installation process. Your engineer may need to modify the existing pipework, or they may need to cap the existing pipework and install new elements in the new location. This change may cause your installation to take an extra day.

It’s worth noting that the further you choose to install your new boiler, the longer the installation is likely to take – and the higher the costs.

Because of their innovative features and ease of use, smart thermostats are becoming increasingly popular. You can use your smartphone, tablet, or another device to control your heating from anywhere. Some smart thermostats can also learn your central heating habits and program themselves to follow your usual schedule.

Other Advanced techniques 

Our company has a deep clean designed to remove any sludge, debris, or rust from your central heating system. It could help to ensure that your new system operates as efficiently as possible. This entails rapidly circulating a chemically infused liquid through your radiators and pipes. This time-saving procedure can take up to 5 hours to complete.

A deep clean that is designed to get rid of any sludge, debris or rust in your central heating system, our tools could help to ensure that your new system functions as efficiently as possible. This involves sending a chemically infused liquid at a high velocity through your radiators and pipes. This highly-effective process can take up to 5 hours to complete.

If you currently have an older system, the pipework may not be suitable for the new boiler you want to be installed. If the size of your gas installation pipework doesn’t meet the requirements for your new boiler, it will need to be changes.
