5 Necessities When Switching From an Electric to a Gas Water Heater
by Bill Turner
Switching from electric to gas can save you money when it comes to heating your water in the long run. There are a few additional necessary steps if you choose to go this route.
1. Run a Gas Line
If your home doesn't currently have gas, then the utility company must come out and run a gas line from the main supply to your home. In homes with existing gas service, the task of running gas to the water heater can typically be done by the same plumber that is installing the water heater. You or your plumber may need to secure permits in order to install an additional line to the water heater.
2. Enlarge Water Heater Closet
Gas water heaters typically require more airflow and ventilation to work properly and with maximum safety. For this reason, the water heater must be sized to the space in which it will be installed so that there is plenty of room around it for air circulation. This may mean installing a smaller tank if the old electric heater was in an overly small closet. If you prefer a larger tank, then it may be necessary to enlarge the space where the new gas heater will be installed.
3. Install a Flue
Unlike electric heaters, gas water heaters require a flue to vent combustion gasses out of the home. If your home currently has other gas appliances, then your plumber may be able to attach the water heater to the existing flue system. Otherwise, a new flue must be installed through the ceiling or wall of the heater closet and up through the roof.
4. Increase Ventilation
Much like airflow, ventilation is vital for a gas water heater. It ensures proper combustion of the gasses and minimizes the chances of harmful carbon monoxide buildup in the water heater closet. You can have a dual system installed with the flue, which brings in fresh air while pushing out gasses. There are passive ventilation systems as well as those that use fans to help keep the air moving through the vents.
5. Add Safety Monitoring
Carbon monoxide is a real threat with any gas appliance, but you can negate nearly all risks with proper safety monitoring. You must install a carbon monoxide alarm near the water heater. There are alarms that connect to smart home systems as well as alarm systems if you prefer a more versatile monitoring option.
Contact a water heater installation service if you are ready to switch from electric to gas for your hot water needs.
