How to Choose the Best Power Vented Gas Water Heater for Your Needs

How Do Power Vented Gas Water Heaters Work?

Before we dive into the specifics of choosing a power vented gas water heater, let’s go over the basics of how they work.

A power vented gas water heater is similar to a standard gas water heater in that it uses natural gas to heat the water. However, a power vented gas water heater is equipped with a fan that helps expel the combustion gases from the unit. This allows the water heater to be installed in areas where there isn’t a natural draft, such as in a basement or utility closet. 

Some benefits of a power vented gas water heater include: 

- Greater energy efficiency
- A constant supply of hot water 
- Lower operating costs 
- Quieter operation 

What to Consider When Choosing the Best Power Vented Gas Water Heater

When it comes to choosing the best power vented gas water heater for your home, there are a few factors to consider. 

1. Size 

The first thing to consider is the size of the unit. A power vented gas water heater comes in various tank sizes, ranging from 40 to 75 gallons. The size you choose will depend on the hot water demand in your home. 

2. Energy Efficiency 

Another important factor to consider is the unit’s energy efficiency. Look for a model with a high energy factor (EF) rating. The EF rating measures the unit’s energy efficiency, with a higher number indicating greater efficiency. 

3. Venting Requirements 

Since a power vented gas water heater expels combustion gases through a vent, it’s crucial to comply with manufacturer’s venting requirements. If the unit is not installed correctly, it could Lead to harmful gases leaking into your home. 

4. Cost 

Of course, cost is also an essential factor to consider when choosing a power vented gas water heater. While a more expensive unit may seem daunting, it could save you money in the long run with lower operating costs. 

Now that we’ve covered what to look for when choosing a power vented gas water heater let’s go over some of the best options currently available.
