A power vent water heater is a type of water heater that uses a fan to push exhaust gases created during the heating process outside through a vent pipe. This allows for more efficient operation and energy savings compared to conventional atmospheric vent water heaters. When shopping for a new power vent water heater, the price is often a major consideration. In this article, we’ll break down the factors that influence power vent water heater costs and provide average price ranges so you know what to expect.

What is a power vent water heater?
A power vent water heater, also known as a direct vent water heater, is a gas-fired water heater designed to be vented horizontally through an exterior wall rather than vertically through the roof. It uses a fan or blower to force combustion gases through plastic pipes to the outdoors. This creates a “power vented” system.
The key components of a power vent water heater include:
– Gas burner – Heats the water in the tank. Runs on natural gas or propane.
– Blower motor – Provides forced draft to vent exhaust gases.
– Vent tubing – Plastic pipes that run from the water heater to the exterior. Usually 3-5 inches in diameter.
– Vent termination – A hood installed on the exterior wall that allows gases to vent outdoors.
– Electronic ignition – No standing pilot light. Only fires burner when heat is needed.
– Flue – Carries combustion byproducts from the burner to the vent tubing.
– Condensate drain – Collects and disposes of condensate from the flue gases.
Some of the benefits of a power vent water heater compared to conventional models include:
– Increased energy efficiency – Uses less energy by completely venting all exhaust.
– Flexible venting options – Can be vented horizontally through walls up to 50 feet away.
– Low standby heat loss – No chimney effect wasting heat.
– Peace of mind – Exhaust gases are safely vented to the outdoors.
– ADA compliance – Can be installed at any height without vertical venting.
Factors That Influence Cost
When buying a new power vent water heater, the price can range quite a bit depending on the size, fuel type, efficiency rating, brand, and features. Some of the key factors that affect the cost include:
Tank Capacity
The tank capacity, measured in gallons, determines how much hot water the heater can store and deliver. Larger tanks cost more but provide more hot water. Tank sizes typically range from 30 gallons up to 120 gallons for residential power vent models. Here are some example price ranges:
– 30-50 gallon tank – $400-$1200
– 75-100 gallon tank – $800-$2000
– 105-120 gallon tank – $1200-$2500
Fuel Type
Power vent water heaters require gas for fuel. You can choose between natural gas and propane (LP) models. Propane heaters often cost $100-$500 more due to the tankless features.
Energy Factor
The energy factor (EF) measures how efficiently the heater uses energy. The higher the EF, the more efficient the water heater. High-efficiency models with an EF of .67 or higher cost $200-$500 more than standard models with an EF around .60.
Venting Materials
Power vent water heaters are designed to be vented horizontally with plastic piping. More affordable units come with 3-inch diameter PVC pipes. Upgrading to 4-inch or 5-inch pipes adds $50-$100 to the total cost. Stainless steel venting can add $200-$300.
Special Features
Upgraded features like WiFi monitoring, leak detection, recirculation pumps, and multiple anode rods add to the price. Expect to pay $50-$300 more for models with extra functions and accessories.
Brand
The brand and quality of the unit impacts price as well. In general, you can expect to pay:
– $400-$800 for budget/off-brand models
– $800-$1500 for mid-range brands like Rheem, AO Smith, and Bradford White
– $1500-$2500+ for premium brands like Rinnai and Noritz
Professional Installation
DIY installation can save on labor costs, but having a professional install your new power vent water heater averages $400-$1200 depending on the complexity. Many homeowners choose to have installation handled by a licensed plumber or HVAC technician for safety and to ensure proper code compliance.
Average Cost by Gallon Capacity
Here is an overview of the average price range for common power vent water heater sizes, excluding professional installation costs:
| Gallons | Average Cost Range |
|---|---|
| 30-50 | $400 – $1200 |
| 55-66 | $600 – $1500 |
| 75-100 | $800 – $2000 |
| 105-120 | $1200 – $2500 |
As you can see, the average cost ranges from a few hundred dollars for small capacity units up to $2500 or more for extra large tanks. The good news is there are power vent models available at various price points to suit different budgets and hot water needs.
Saving on Installation Costs
One way to save money when buying a new power vent water heater is to handle the installation yourself if permitted by local codes. Here are some tips on installing it as an affordable DIY project:
– Review the manufacturer’s installation guide for safety tips and step-by-step instructions.
– Shut off water and gas supply lines and drain the old tank.
– Determine the optimal location – garage, laundry room, closet, etc.
– Install approved venting materials through the exterior wall.
– Carefully connect the water, gas, and electrical lines.
– Attach earthquake strapping and condensate drains.
– Adjust thermostat and confirm proper operation.
– Budget $100-$300 for venting supplies, pipes, and wiring.
– Total DIY installation time is 6-10 hours for most homeowners.
While a professional installation generally costs $400-$1000, a DIY job can be done for under $500 in most cases, saving you quite a bit of money. Just be sure to get proper permits and ensure safe operation.
Power Vent Water Heater Replacement Costs
If you need to replace an existing power vent water heater rather than installing a new unit in a new location, your costs may be lower in some areas. Key factors in replacement costs include:
– No need to purchase new venting – Reuse existing exhaust pipes. Saves $100-$300.
– May only need minor electrical work – Expect $50-$100 in electrical costs.
– Potential pipe modifications – Could require $50-$200 in plumbing modifications.
– Removal of old unit – Budget $50-$150 for removal and disposal fees.
– Labor – Hiring a pro for a replacement averages $350-$850. DIY is under $500.
In many replacement scenarios, the total costs can be $200-$800 less than installing a power vent water heater in a completely new spot. Reusing existing vents, wiring, and pipes helps lower the overall replacement costs.
Comparing Installation vs. Replacement Cost
Here is a side-by-side comparison of typical installation and replacement costs:
| Cost Factor | New Installation | Replacement |
|---|---|---|
| Water heater unit | $400 – $2500 | $400 – $2500 |
| Venting materials | $100 – $300 | $0 |
| Electrical work | $100 – $300 | $50 – $100 |
| Plumbing modifications | $100 – $300 | $50 – $200 |
| Removal fees | $0 | $50 – $150 |
| Labor fees | $400 – $1000 | $350 – $850 |
| Total Cost Range | $1100 – $4400 | $900 – $3850 |
As you can see, directly replacing an existing heater can potentially save $200-$800 compared to installing a completely new power vent model from scratch.
Ways to Save on Power Vent Water Heater Costs
Here are some tips for getting the lowest price on your new power vent water heater purchase and installation:
– Get multiple quotes – Prices can vary greatly between plumbing companies.
– Consider lower tank capacity – Buy only as much capacity as you need.
– Shop end of season sales – Dealers offer discounts on remaining inventory in fall/winter.
– Choose basic models – Avoid unnecessary premium features you may not use.
– Install it yourself – DIY installation saves hundreds if permitted.
– Reuse vents/pipes – Don’t pay for new venting when replacing existing heater.
– Enroll in rebate programs – Many utility companies offer rebates of $100-$500.
– Use tax credits – Can qualify for renewable energy tax credits up to $500.
Taking advantage of these savings opportunities can potentially knock off 10-40% from your total power vent water heater costs.
Conclusion
The cost of a power vent water heater can range from as low as $400 for a basic 30-gallon model to $2500 or more for a premium 120-gallon tank. Key factors impacting price include tank capacity, fuel type, energy efficiency, venting needs, brand, and extra features. Installation costs also vary significantly by location and complexity. While purchasing and installing a new power vent model averages $1100-$4400, replacing an existing unit can be $200-$800 cheaper by reusing venting and existing connections. With smart shopping and cost-saving installation options, you can find an affordable power vent water heater suitable for your budget and hot water requirements.
