1. Delivery of the Boiler
   Your new boiler will be safely delivered to your home.

2. Removal of Existing Equipment
   We will disconnect and remove your old boiler if necessary.

3. Connecting the New Boiler

   • Installation of the new boiler in the same location as the previous one.
   • Connection to existing plumbing, gas, and electrical lines.
   • Integration with the existing heating system, including radiators or baseboard heaters.

4. Standard Venting
   Includes installation of a flue system for proper ventilation, adhering to safety codes.

5. System Testing
   Comprehensive testing of the boiler to ensure it operates safely and efficiently.

6. Basic Cleanup
   Disposal of the old boiler and materials, leaving your space tidy.

Additional Costs May Apply for Non-Standard Installation

Some situations may require work beyond standard installation. Examples include:

• Moving the boiler to a different location.
• Upgrading electrical or plumbing systems.
• Installing a complex or high-efficiency venting system.
• Adding a condensate pump or other accessories.

Please note that the boiler cannot be sold without installation, as it requires a certified technician to carry out the installation for safety reasons.
