Water Heating · Power-vented
Dependable Hot Water. Built for Everyday Living.
Discover reliable gas storage water heaters with power-assisted venting, available in configurations designed to support your household’s hot water needs.
How it works
What is a power-vented water heater?
A power-vented gas water heater stores heated water in a tank and uses a powered blower to push combustion gases out through an approved venting system.
Power venting is a venting configuration. It does not by itself mean the water heater is more energy efficient.
- Cold water enters the bottom of the tank.
- A gas burner under the tank heats the stored water.
- A blower on top pushes the exhaust out through a vent pipe.
- Hot water leaves from the top of the tank when you open a tap.
Why power-vented
Benefits of power-vented water heaters
Reliable stored hot water
A full tank of hot water ready when you need it.
Powered exhaust venting
A blower pushes exhaust out, so it can often vent sideways through a wall instead of a chimney.
Different tank capacities
Sizes to suit smaller and larger households.
Familiar storage-tank operation
Works the way most households are used to.
Options for a range of households
Standard and higher-efficiency models are available.
Sizing
Understanding tank capacity
No tank size suits every household of a given size. How and when you use hot water matters as much as how many people live there.
Tank capacity
How much water the tank holds. Common residential sizes run from about 40 to 75 gallons (roughly 150 to 285 litres).
First-hour rating
How much hot water the heater can deliver in an hour starting from a full tank. It is the best single measure of a busy morning.
Recovery rate
How quickly it reheats water after the tank has been drawn down.
Simultaneous use
Showers, laundry and the dishwasher at the same time draw the tank down faster.
Household demand
Two people who shower at different times may need less than a smaller household that all showers at once.
Compare
Power vent or tankless?
| Compare | Power-vented tank | Tankless |
|---|---|---|
| How it heats | Stores heated water in a tank | Heats water as it flows |
| First-hour delivery | Set by tank size and first-hour rating | Not applicable; limited by flow rate instead |
| Continuous flow | Runs out when the tank is drawn down, then recovers | Continuous, but only up to its rated flow |
| Venting | Blower-assisted vent, often through a wall | Dedicated vent; condensing models use plastic pipe |
| Maintenance | Flushing, anode checks | Descaling, especially with hard water |
| Space | Floor space for the tank | Compact, wall-mounted |
| Installation | Gas line, vent route, outlet for the blower | Larger gas supply, vent, condensate drain |
| Operating costs | Includes standby losses from the tank | No tank losses; efficiency depends on the model |
Running costs
What would a power-vented tank cost to run?
Includes the heat a tank loses while standing. A like-for-like replacement often changes reliability more than running cost.
That suggests about 150 litres of hot water a day. Change it under the assumptions if you know your use.
Adjust the assumptions
Incoming water is colder in winter, which raises the energy needed. The default is a yearly average for your province.

How this is worked out
- Hot water: about 150 litres a day, heated from 10 °C to 55 °C (about 2,865 kWh of heat a year).
- Efficiency is based on each system’s UEF rating. Storage tanks also lose heat while standing, which matters more when a household uses less hot water than the rating test assumes.
- Power-vent blowers, tankless electronics, fixed monthly charges and maintenance are not included.
- The 10-year figure is the yearly difference × 10 at today’s prices. It does not include equipment, installation, rebates or financing.
- This is an estimate, not a guarantee. Real use varies with household habits and the season.
Incentives
Power-vented water heater rebates
Answer a few questions to see which programs you may qualify for. You do not need to give us any contact details.
Installation
Installation considerations
Gas connection
A properly sized gas line to the water heater.
Electrical supply
An outlet for the blower. Without power, the heater cannot fire.
Approved venting route
Vent pipe to the outside, within the manufacturer’s length and clearance limits.
Combustion air
Enough air for the burner to work safely.
Tank dimensions
Height and diameter must fit the space, with clearances.
Drainage
A drain or pan for the relief valve and for flushing.
Local code requirements
Gas, venting and safety requirements must all be met.

Questions
Frequently asked questions
What is a power-vented water heater?
A gas storage water heater with a blower that pushes its exhaust out through a vent pipe, instead of relying on a chimney to draw it up naturally.
How is it different from a conventional gas water heater?
Both store and heat water the same way. The difference is venting: a conventional unit vents up a chimney by natural draft, while a power-vented unit uses a blower and can often vent through a side wall.
Does it require electricity?
Yes. The blower needs power, so it needs an outlet nearby.
How much hot water does a storage tank provide?
It depends on tank size and the first-hour rating. Once the stored hot water is used, it takes time to recover.
How long does a power-vented water heater last?
Many storage tanks last about 8 to 12 years, depending on water quality and maintenance.
Can I replace my existing tank with a power-vented model?
Usually, with a suitable vent route and an outlet. If your current tank is rented, check your rental agreement’s terms for returning or buying out the tank first.
Is power venting more efficient?
Not automatically. Power venting is about how exhaust leaves the home. Efficiency depends on the model’s UEF rating, so compare those.
What maintenance is required?
Periodic flushing to remove sediment, checking the anode rod, and keeping the vent and blower clear.
Are rebates available?
None of the provincial programs we track currently offer a rebate for a gas storage water heater. The checker above shows what is listed for your province.
What happens during a power outage?
The blower stops, so the heater cannot heat more water. Hot water already in the tank is still usable.
