How to Install a Gas Wall-Hung Boiler (Fun & Easy Guide!)

1. Before Installation: Give Your Home a “Health Check”

Before welcoming your boiler home, make sure your house is ready! Check if the gas line is in place, water pipes are clear, and a power outlet is reserved. Also, ensure the wall is strong enough to hold the boiler (usually over 50kg). Just like checking a new apartment before moving in—good prep means smooth setup!

2. Pick the Perfect Spot: Fresh Air & Dry Space

Boilers love to “breathe”! Ideal spots are the kitchen or balcony, where airflow is good. Avoid damp bathrooms or tiny enclosed rooms. Leave at least 30cm of space above and on both sides for easy maintenance—don’t let your boiler become a “cabin fever” heater stuck in a corner!

3. Pro Install Only: Safety First!

Gas appliances? Never DIY! Installation must be done by a licensed technician from your gas company or the brand’s official service. They’ll safely connect the gas line, water pipes, and flue, and test for leaks. The exhaust pipe must vent outside—never into a shared chimney or indoor space!

4. Test Run: Power Up the “Warm Heart”

After setup, the technician will test the system: fill water, release air, set pressure, and ignite. You’ll hear beeps, see the screen light up—your boiler is alive and “beating”! Slight noise at first is normal; it’ll settle into a quiet rhythm after running a while.

5. Pro Tip: Stay Cozy & Safe

After install, ask for the Certificate of Safe Installation and warranty card. Regularly check for gas leaks (use soapy water on joints), prevent freezing in winter, and turn off the gas valve when away for long. A well-installed boiler will quietly keep you warm all winter—your home’s warmest hero!
