Gas Water Heaters Buying Guide
When it comes to choosing a water heater for your home, there are several options available in the market. However, gas water heaters are a popular choice among homeowners due to their high efficiency and quick heating capabilities. If you are planning to purchase a gas water heater, you need to consider several factors to make an informed decision. This guide will help you understand the essential features you need to look for in a gas water heater and make the right purchase decision.
1. Size and Capacity
The size and capacity of the gas water heater are the essential features you must consider before making a purchase. The size of the water heater will determine its efficiency and how much hot water it can provide in a single cycle. A gas water heater with a higher capacity can heat up more water, making it ideal for large families or properties with high hot water demand.
The water heaters are available in different sizes and capacity. The standard capacity is 40-50 gallons, which is enough to meet the hot water demand of an average household. However, if you have a larger family or high water demand, a larger capacity of 60-80 gallons will be an ideal choice. Always consider your hot water demand and the size of the water heater before making a purchase.
2. Type of Gas Water Heater
There are two types of gas water heaters available, namely storage tank water heaters and tankless gas water heaters.
Storage Tank Water Heaters
These are the traditional gas water heaters with a storage tank that stores hot water until it is needed. They are a popular choice among homeowners due to their affordability and reliability. However, they take up more space and are less efficient than tankless water heaters.
Tankless Gas Water Heaters
These are the modern gas water heater that does not come with a storage tank. They heat water on demand, which means they only consume energy when you need hot water. This feature makes them more energy-efficient, and they take up less space in your home. However, they are costly compared to storage tank water heaters and may require additional installation costs.
3. Energy Efficiency
The energy efficiency of a gas water heater is a crucial factor to consider as it will significantly impact your utility bills. Always choose a gas water heater that has high energy efficiency and is Energy Star certified. The Energy Star certification is proof that the product meets the minimum energy efficiency requirements and is an excellent energy-saving product.
The energy efficiency of the gas water heater is measured by its Energy Factor (EF) rating. The higher the EF rating, the more energy-efficient the water heater is. For example, a gas water heater with an EF rating of 0.67 is more energy-efficient than a water heater with an EF rating of 0.57.
4. Venting System
The venting system is an essential component of a gas water heater, and it ensures safe and efficient operation. The venting system works by removing the harmful gases produced during combustion, such as carbon monoxide, and expelling them outside your home.
There are two types of venting systems available for gas water heaters, namely atmospheric venting and power venting.
Atmospheric Venting
Atmospheric venting is the most common venting system used in gas water heaters. It uses natural convection to vent the harmful gases outside your home. This venting system is suitable for homes that have a vertical vent that extends through the roof of the house.
Power Venting
Power venting uses a fan or blower to expel the harmful gases outside your home. This venting system is ideal for homes that do not have a vertical vent but have a horizontal vent that extends through the wall of the house. Power venting is more expensive than atmospheric venting, but it is more efficient and safer.
5. Warranty and Repair
When purchasing a gas water heater, check the warranty and repair policies. Always choose a gas water heater that comes with a warranty to ensure that you are covered in case of any defects or repairs. The warranty may vary depending on the manufacturer and the model of the gas water heater.
Also, check the repair policy of the manufacturer and whether they have authorized repair technicians in your area. In case of any repairs, it is always better to have authorized repair technicians handle them as they are familiar with the product and can provide quality service.
Conclusion
Choosing the right gas water heater can be a daunting task due to the several options available in the market. Therefore, it is essential to consider the size and capacity, type of gas water heater, energy efficiency, venting system, warranty, and repair policy before making a purchase decision. This guide will help you understand the essential features you need to consider before purchasing a gas water heater and make an informed decision that suits your needs and budget.
