Trusted Hot Water Performance for Homes with Existing Chimneys 

If your home already has a working chimney or vertical flue, a chimney vented water heater remains one of the most reliable and cost-effective hot water solutions available. Bradford White’s chimney vented gas water heaters are engineered for efficient operation in homes that use natural draft venting making them a great replacement for older models with similar setups. 

  

These systems are still used in thousands of Ontario homes today and are known for their simplicity, durability, and performance especially during power outages. 

How Chimney Vented Water Heaters Work? 

Chimney vented (also called atmospheric vent) water heaters operate using the natural upward flow of warm air. When the burner heats the water, it also produces combustion gases, which rise naturally through a metal draft hood and out through the chimney. 

  

This venting method does not require fans or electricity, making it a dependable, low-maintenance choice especially if your home already has a proper flue in place. 

Choosing the Right Water Heater Starts with the Right Info

Can a water heater be vented through a chimney? 

Yes. That’s exactly how chimney vented systems work. If your home has an existing chimney or metal flue, chimney vented heaters are a compatible and affordable option.

How to vent a hot water heater without a chimney? 

If your home doesn’t have a chimney, you’ll need a power vent or direct vent model instead. These use side-wall venting and sealed combustion to safely exhaust gases without a vertical flue.

Why Choose a Bradford White Chimney Vented Model? 

These models are a great fit if: 

  • You already have a functioning vertical chimney 
  • You’re replacing an older atmospheric vent heater 
  • You want a non-powered, electricity-free system 
  • You’re prioritizing simplicity and upfront affordability 

Maintenance Tips For Your Chimney Vent Water Heater 

Although chimney vent systems are straightforward, regular maintenance keeps them running efficiently and safely. Here’s what we recommend: 

  

  • Check chimney draft using a smoke or match test once a year 
  • Inspect the flue and draft hood for signs of rust or blockages 
  • Flush the tank annually to remove sediment 
  • Inspect the chimney liner every 10 years or after major renovations

Frequently Asked Questions

Can I install a chimney vent water heater without a chimney? 

No. These systems require a functioning vertical chimney or flue. If that’s not available, a side-vented (power/direct vent) model is a better fit.

Can you run a direct vent into a chimney? 

No - Direct vent systems are sealed and designed for horizontal side-wall venting. Chimney vent models are the only type made for vertical flue exhaust.

Should a chimney be vented? 

Yes. It must be properly vented to ensure safe removal of combustion gases. Our team will verify your chimney meets all safety requirements before installation.

Do these water heaters work during a power outage? 

Yes. Since chimney vent models use a pilot light and natural airflow, they don’t rely on electricity making them ideal for areas with unreliable power.

What size is best 40 or 50 gallons? 

40 gallons is typically enough for 1–2 people. For households of 3–5, we usually recommend a 50-gallon tank for better comfort and capacity.

Are they energy efficient? 

While reliable, chimney vented models are less efficient than power vent or tankless units. If efficiency is a priority, we can guide you toward upgraded options.
