Key Gas Heater Considerations
If you are replacing an old gas unit or considering switching from electric, here are the factors we review with you:
- Fuel Efficiency: Modern gas heaters are significantly more efficient than older models, offering substantial long-term savings.
- Ventilation Type: We determine if your home needs standard atmospheric venting or a high-efficiency power-vented system.
- Recovery Rate: Gas heaters typically heat water faster than electric models, providing a better recovery rate after heavy usage.
- Location: The unit must be placed where proper venting can be installed, which is why location planning is essential.
Safe Venting and Connection Process
The most critical step in gas water heater installation is ensuring safe and compliant venting. Our process focuses on this area:
- Professional Removal: Safely disconnecting the gas line and water pipes before removing the old unit.
- Venting Setup: Installing and sealing the new vent pipe according to the manufacturer's specifications to prevent carbon monoxide leakage.
- Gas Hookup: Carefully connecting the new gas valve and line, and performing necessary leak tests.
- Pilot Light/Ignition: Safely lighting the pilot or confirming the electronic ignition is functioning correctly.
