How will my boiler installation go?

Here's how a typical boiler installation process goes:

  • 1. The Gas Safe installed will start by removing your existing boiler.
  • 2. They will chemically flush your heating system to ensure optimum efficiency.
  • 3. The new boiler and any additional pipework or equipment will then be fitted.
  • 4. A thorough boiler test is conducted, and all paperwork is completed.

Once the boiler installation is complete, the engineer will guide you through its operations and routine checks.

To keep your warranty in check, the boiler needs to be registered. This will be completed by iHeat for you.

We preform both gas boiler installations and LPG boilers.

Does iHeat offer a Power flush?

We don’t currently offer power flushes, we actually recommend this is done prior to installation to ensure any sludge in the system does not damage the new boiler. All iHeat boilers get a chemical flush, free of charge form our Gas Safe registered engineers once installed.

Show More

What is the difference between a Power Flush and a Chemical Flush?

While both a power flush and chemical flush are designed to provide a deep cleanse of your central heating system, aiming to remove sludge, dirt and debris from the pipes, there are some key differences between the two. A power flush works by flushing hot water and a combination of chemicals at very high pressure through heating systems, a chemical flush does not rely on high pressure. Instead, chemical flushes use gravity and a cleaning inhibitor to empty the system of debris and then later refill it with clean water.
