What Happens After Your Boiler is Installed By iHeat?

In this guide, we’ll be answering some of the most frequently asked questions about what happens after your new boiler installation.

What Happens After Your Boiler is Installed By iHeat?

At iHeat, our goal is to make the process of buying and installing a new boiler a lot more quick and simple for customers and we talk a lot about how our service works in three simple steps, however, you may be wondering what happens after this. In this guide, we’ll be answering some of the most frequently asked questions about what happens after your new boiler installation.

Will You Dispose of My Old Boiler?

Yes, on the day of your boiler installation, the iHeat Gas Safe engineer will remove your old boiler if it is safe to do so and will dispose of it afterwards, along with all the packaging from the new boiler, leaving your home as clean and tidy as when they arrived.

iHeat 10 Year Warranty

Who Will Activate My Boiler Warranty?

Following your new boiler installation, the engineer will activate the warranty with the manufacturer. This is so that you can benefit from the exclusive extended warranty that we offer which you may not otherwise benefit from if you were to register the boiler yourself.

What Should I Do If I Have an Issue With My Boiler?

Boiler Issues


If you notice an issue with your new boiler after it has been installed, the next steps you should take depend on the following:

Is the Blue Pilot Light Yellow? / Can You Smell Gas?

If you can smell gas coming from your boiler or a pipe, or if you notice that your boiler pilot flame has turned yellow, you may have a gas leak. If this happens, make sure to call the National gas Emergency Helpline immediately on 0800 111 999 and report the suspected gas leak.

Whilst waiting for the Gas Safe engineer to arrive, make sure to do the following:

  • Turn off all appliances

  • Open all doors and windows in your home to allow fresh air to enter

  • Turn off the gas at the mains

  • Make sure there are no natural flames e.g. kitchen hobs, lighters, lit candles

  • Leave the house as soon as possible

Is Your Boiler Leaking Water?

If your boiler is leaking, make sure to first turn off the boiler’s electricity supply and water supply to avoid the risk of electric shock and reduce the chance of damage to your heating system. 

Then, take a look at the boiler pressure gauge on the front of the boiler. If the arrow is pointing to the upper red zone, the water may be leaking from the pressure relief valve. Check that the filling loop, key or level isn’t stuck open and allowing water into the system. If this isn’t open, wait for the system to cool down and release some of the boiler pressure by bleeding the radiators
If your boiler continues to leak after it is switched back on, turn it off again and give us a call on 0333 305 6880 and either one of our iHeat engineers or your manufacturer (under the warranty) will come out to resolve the issue.

Is Your Heating Not Working Properly?

Is Your Heating Not Working Properly?


If your heating won’t come on when you need it to after your boiler installation, there could be a number of causes behind it.

First, make sure to check that your wireless thermostat isn’t low on charge.

Did you know that low batteries in digital thermostats are one of the most common causes of issues with home heating? Thermostat batteries typically last 8-12 months, so if you've noticed problems with your heating around 8 months after your boiler installation, it may be time to replace them.

If your thermostat has new batteries and your heating system still isn’t working, make sure it is programmed correctly. Knowing how to control your heating with your thermostat is essential if you want your heating to come on when you need it and turn off when you don’t. It may also be worth asking any other household members if they have changed any settings on it as this is a more common cause of issues than you may think.

You could make significant savings with smart heating controls. Check out our guide to the benefits of a smart thermostat and find out what the best smart thermostats of 2022 are.

Boiler Thermostat


If your thermostat is programmed correctly and your heating still isn’t working, check your boiler for any error codes. These are small codes made up of numbers and letters that can help tell us what the issue is. If you see an error code, make sure to check your manufacturer’s user manual to identify what it means and follow the steps from there.

If you are unable to find the manual from your boiler installation, you can usually find downloadable guides on the manufacturer’s website, or alternatively, you can check out our guides to the most common boiler error codes:

If you cannot see a code, or if you are unable to find it in the manufacturers’ manual, give our team at iHeat a call and one of our team will be able to help, either by sending out our own heating engineer if it is an issue with the  boiler install, or putting you in touch with the manufacturer if it is an issue with the boiler itself and it falls under the terms of your warranty.

What About My Annual Service?

When it comes close to your annual boiler service being due, we will send you a reminder via email or post. From here, you can either get in touch with our team to arrange one of our engineers to come out, or alternatively, you can arrange a Gas Safe engineer yourself to carry out the service and your warranty will still remain valid.
