In contrast, gas water heaters, including propane models, tend to be more expensive to purchase and install. For example, a 40-gallon gas water heater can cost between $1,400 and $2,800 initially. This higher cost is partly due to the need for additional infrastructure such as gas lines and ventilation systems. Installation for gas units can be significantly higher, ranging from $1,000 to $2,000, compared to $700 to $1,000 for electric models.
Electric water heaters also have fewer components, which further contributes to their lower purchase price compared to gas models. While initial costs matter, weighing them against long-term operating costs and performance is crucial for an informed decision.
Long-term Operating Costs
Although electric water heaters have lower initial costs, long-term operating expenses can differ. Propane water heaters generally consume about 30% less energy than electric counterparts, resulting in lower operational energy costs. On average, a household using propane for water heating can save approximately $174 annually compared to using electric water heating.
However, propane water heaters can incur higher maintenance costs, potentially offsetting some savings. Electric water heaters often require more frequent replacements of heating elements, leading to increased long-term costs. In regions with high electricity rates, the long-term cost of running electric water heaters can be significantly higher compared to propane options.
Propane prices can fluctuate, impacting the overall operating costs of gas water heaters. Conversely, electric water heaters usually offer more stable costs due to consistent electricity pricing. These factors emphasize the importance of evaluating both immediate and long-term costs when selecting a water heater.
Installation Requirements
Installation requirements can vary significantly between electric and propane water heaters. Electric water heaters usually need less extensive infrastructure, making installation easier and often cheaper. Both types must comply with local plumbing codes, and permits may be required based on local building regulations.
Gas water heaters must be installed at least 18 inches above the floor to prevent fire hazards. Additionally, proper ventilation is crucial for gas units to avoid carbon monoxide buildup and ensure safe operation. Gas water heaters need a sediment trap to prevent debris from damaging the gas valve. These requirements can make gas water heater installation more complex and costly.
