If you are planning to install a boiler or thinking to replace one, there is a list of things you need to consider. While the list might not be inclusive, it'll serve a guide for those seeking out a detailed insight on installation and procedures regarding it. Installing a new boiler can be often stressful, so here's a simple guide that’ll possibly help you cover what the installations entail and what happens afterwards.

Types of Boilers

Basically, there are three types of boilers i.e., the combi, the conventional and the system boiler. Choosing the one for your home depends upon certain factors including a gas connection, hot water requirement, availability of space and the efficiency. Changing the boiler to the same type makes installation easier while switching to a new energy-efficient boiler undoubtedly outweigh disruptions.

Finding A Safe Boiler Installer

Once you have finalized a boiler, now is the time to hire an engineer. Your Energy Solutions are Gas Safe registered. Also, you should only opt for a registered gas engineer so that you don't have to face any legal issues in the future.

Things to Expect During the Installation

Gas engineers will undoubtedly try to make the installation service as simple as possible. They bring all the materials with them and work safely, ensuring 100% adherence to legal issues. Further, it's a stepwise step process and here's what you need to expect

Before Work

The gas engineer will check a few things – how many radiators does it give, the water pressure, the total number of bathrooms in the property and the current position of boiler and flue

On the Site

If it’s a straightforward swap, say combi to combi, you should expect the work within a day. However, if it’s a much older boiler system or you're changing the type, the work may prolong due to complications in the installation. Additionally, your presence is essential to understand the new boiler controls.


Boiler costing depends on the type of boiler you purchase. While it can be expensive, but most of the times, it depends upon whether you're going for the basic version or a complete system change followed by additional pipework.


In order to comply with Building Regulations and Gas Safe rules, all Gas Safe businesses need to notify the local authorities before they install a new gas appliance. Therefore, make sure you're clear about this before you seek the service.

Post Installations Service

Almost all the reputable companies offer a guarantee on their service. You should check about all the points as the part of the post-installation service. Meanwhile, if you're concerned about the safety of the new boiler installation, don’t hesitate to follow up them. They're obliged to either reimburse you for the cost of hiring a new engineer or put right problems that they’ve created.

Requirements for A Good Boiler

A boiler generates large-quality steam; therefore, here are the requirements

  • Must contain enough steam and water storage capacity to prevent variation in steam pressure or water level
  • Must be able to generate steam at a preferred rate, preferred pressure and temperature with minimum fuel consumption
  • Construction must be simple that includes smooth ease of inspection with accessible parts in case there requires a repair
  • There must be minimum frictional power loss during the flow of hot gases and water/steam
  • Boiler must have the capacity to start rapidly from cold
  • Boiler must have a constant and thorough flow of water
  • It should absorb less floor area and space

Common Circumstance of Boiler Installations

New Boiler Is Not A Standalone Appliance

When you install a boiler, you're securing a new appliance onto the existing heating system. Likewise, the heating system that you've been using when paired with a sparkling new boiler may cause immediate damage.

The radiator builds sludge deposits when hooked to a new boiler, the sludge flows from the radiator to the boiler. Also, sludge causes inefficiency thereby increasing the energy bills. Make sure you avoid such things. Thorough flushing your heating system extends your boiler’s lifespan.

Radiator Clogs and Heat Exchanger

Never allow your brand new boiler’s heat exchange to be clogged with sludge. The main role is to transfer heat from the boiler to water that runs through the heating system’s pipes. If layered with sludge, heat transfer may be inefficient.

But installing a new boiler after a thorough system flushing can reduce your heating bill. But before that, you need to find out if sludge has build up. Place one hand over the bottom and another over the top, gauge whether the temperature difference persists or not.

If the bottom is cooler than the top, sludge is preventing an even flow of heat throughout the radiator. You can fix the issue with a thorough cleaning.

Cleaning with A Power Flush

Cleaning the system requires pressure to force water throughout the system. However, this task includes some risks. If there's a weak spot in the system, it might burst, causing hefty damage. Make sure that your system is strong and stable. By this, you can reduce the risk for future cleaning by timely maintenance.

Final Wrap

In a nutshell, Boiler installation is undoubtedly a complex procedure, it equally needs maintenance. Talk to your local gas boiler installations to know more.
