Water heaters are an essential part of any household. They provide you with hot water for showers, washing dishes, and doing laundry. However, with so many options available, choosing the right type of water heater can be a daunting task. Two popular options are electric and gas tankless water heaters. In this article, we will compare the two and help you decide which one is better for your home.

Energy Efficiency

When it comes to energy efficiency, electric and gas tankless water heaters have their pros and cons. Electric tankless water heaters have an energy factor (EF) of 0.98, which means that 98% of the energy input is converted into hot water. On the other hand, gas tankless water heaters have an EF of around 0.82, which means that they convert about 82% of the energy input into hot water.

Electric tankless water heaters are more energy-efficient because they do not suffer from standby heat loss like gas tankless water heaters. Standby heat loss is the heat that is lost from the water heater to the surrounding air, even when no hot water is being used. However, gas tankless water heaters are still more efficient than gas storage tank water heaters, which have an EF of around 0.60.

In terms of cost, electric tankless water heaters are generally more expensive than gas tankless water heaters. However, they are cheaper to install, and their energy efficiency can make up for the initial cost over time. Ultimately, the decision between electric and gas tankless water heaters depends on your energy needs and budget.

Installation Cost

The installation cost of a water heater is an important consideration when choosing between electric and gas tankless water heaters. Electric tankless water heaters are generally cheaper to install than gas tankless water heaters. This is because electric water heaters do not require venting or gas lines, which can be costly to install.

The installation of an electric tankless water heater typically involves mounting the unit on the wall and connecting it to the water and electrical supply. This can be done by a licensed electrician, and the installation cost can range from $500 to $1,500, depending on the complexity of the installation.

In contrast, the installation of a gas tankless water heater involves venting and gas line installation. This requires a licensed plumber and can cost between $1,000 and $3,000, depending on the complexity of the installation. However, gas tankless water heaters have a longer lifespan than electric ones and can last up to 20 years with proper maintenance.

When choosing between electric and gas tankless water heaters, it is essential to consider the installation cost and the lifespan of the unit. It is also important to factor in the cost of utilities and maintenance over time.

Maintenance Cost

Maintenance is another factor to consider when choosing between electric and gas tankless water heaters. Electric tankless water heaters require less maintenance than gas tankless water heaters. This is because gas tankless water heaters have more components, such as the gas line, venting, and flame sensor, that require regular maintenance.

The maintenance cost of a gas tankless water heater can range from $100 to $200 per year, depending on the extent of the maintenance required. This includes cleaning the burner, checking the gas line, and inspecting the venting system. In contrast, electric tankless water heaters require little to no maintenance, which can save you money over time.

Performance and Capacity

Performance and capacity are also important factors to consider when choosing between electric and gas tankless water heaters. Both types of water heaters provide instant hot water, but gas tankless water heaters typically have a higher flow rate than electric ones. This means that they can provide hot water to multiple fixtures at once, such as a shower and a dishwasher.

Electric tankless water heaters have a lower flow rate and may struggle to keep up with the demand for hot water in larger households. However, they can be installed in multiple locations in the house, which can help to distribute hot water more evenly.

When it comes to capacity, gas tankless water heaters have a larger capacity than electric ones. This means that they can provide hot water for a longer period before running out. However, electric tankless water heaters can be installed in multiple locations, which can help to distribute hot water more evenly.

Ultimately, the decision between electric and gas tankless water heaters depends on your household’s needs and budget. Electric tankless water heaters are more energy-efficient, cheaper to install, and require less maintenance. Gas tankless water heaters have a longer lifespan, a higher flow rate, and a larger capacity. Consider all the factors before making a decision, and choose the type of water heater that best suits your needs.

Conclusion

In conclusion, choosing between electric and gas tankless water heaters depends on several factors, including energy efficiency, installation cost, maintenance cost, performance, and capacity. Electric tankless water heaters are more energy-efficient and cheaper to install, while gas tankless water heaters have a longer lifespan, a higher flow rate, and a larger capacity.

When making a decision, consider your household’s needs and budget. Both types of water heaters have their pros and cons, and it is essential to weigh them carefully before making a choice. At Gogo Gidget, we recommend consulting with a licensed professional plumber or electrician to determine which type of water heater is best for your home.

Performance and Capacity

When it comes to performance and capacity, both electric and gas tankless water heaters have their advantages and disadvantages. Electric tankless water heaters have a lower flow rate than gas tankless water heaters, which means that they cannot supply as much hot water at once. This can be a problem if you have a large household with high hot water demands.

Gas tankless water heaters, on the other hand, have a higher flow rate and can supply more hot water at once. This makes them ideal for larger households with high hot water demands. However, gas tankless water heaters require a larger gas line and ventilation system, which can be costly to install.

Another factor to consider is the temperature rise, which is the difference between the incoming water temperature and the desired hot water temperature. Electric tankless water heaters have a lower temperature rise than gas tankless water heaters. This means that they may struggle to provide hot water in colder climates.

Ultimately, the choice between electric and gas tankless water heaters depends on your household’s hot water needs. If you have a small household with low hot water demands, an electric tankless water heater may be sufficient. However, if you have a large household with high hot water demands, a gas tankless water heater may be a better option.

Conclusion

In conclusion, electric and gas tankless water heaters both have their pros and cons. Electric tankless water heaters are more energy-efficient and cheaper to install, but they have a lower flow rate and may struggle in colder climates. Gas tankless water heaters have a higher flow rate and can supply more hot water at once, but they are more expensive to install and have higher standby heat loss.

Based on our comparison, we recommend that households with low hot water demands and moderate climates consider electric tankless water heaters. On the other hand, households with high hot water demands and colder climates should consider gas tankless water heaters.

When choosing a water heater, it is important to consider your household’s hot water needs, budget, and climate. It is also essential to factor in the installation and maintenance costs over time. With proper research and consideration, you can choose the right type of water heater that suits your household’s needs and provides you with hot water convenience for years to come.
