Hot Water Heater Buying Guide Basics – Common Types of Water Heaters

There are several different types of water heaters to choose from. Each type offers different advantages and disadvantages and will be more suitable in some households than others. 

Before you buy a new hot water heater, familiarize yourself with these different options.

When it comes to different types, here’s what to know when buying a hot water heater.

Gas Hot Water Heaters

Hot water heaters that are powered by natural gas are very common in households throughout Canada, including in Edmonton. This type of water heater is often recommended by hot water tank buying guides and heating and plumbing contractors in Edmonton because of its various advantages.

Pros

• Water is heated faster than with electric water heaters
• More cost-effective in the long run (due to the low cost of natural gas)
• In the case of a power outage, you will still have hot water

Cons

• More difficult and expensive to install
• Typically larger than electric heaters

Electric Hot Water Heaters

Although less common than gas water heaters, electric water heaters can also be a suitable option for some households.

Pros

• Easier installation (than gas water heaters), as no venting is required
• Usually less expensive than gas heaters
• Physically smaller than gas heaters

Cons

• Cost of electricity may be higher than natural gas, making an electric water heater more expensive to run in the long term
• If the power goes out, you may not have hot water

Propane Hot Water Heaters

Hot water heaters that run on propane are also less common than gas water heaters. However, they do have several advantages. Therefore, we’ve included them in this 2025 hot water tank buying guide.

Pros

• Water is heated quickly
• Doesn’t rely on electricity (in case of a power outage)
• More cost-effective than electric water heaters
• More environmentally friendly than natural gas water heaters

Cons

• More difficult to install
• More expensive to buy and install

In addition to these three types of traditional hot water heaters, you also have the option of going tankless. 

Tankless water heaters can be electric or gas-powered. Like traditional water heaters, each type has different advantages and disadvantages, including initial and long-term costs, maintenance needs and efficiency.

For a detailed list of pros and cons, and our recommendation for the best tankless water heater, check out our article about tankless water heaters.

Tankless water heater vs water heater

Tankless hot water heaters offer many advantages over traditional hot water tanks. However, in this hot water heater buying guide, you’ll discover that they are not for everyone. 

Here’s what to know when buying a hot water heater that’s tankless.

What is the difference between a tankless water heater and a regular water heater?

The difference between a tankless water heater vs a traditional water heater is the tank. 

A traditional water heater stores preheated water in a tank. When water is required, the hot water from the tank is delivered. The water heater then refills the tank and heats more water to be kept on standby.

A tankless water heater, on the other hand, does not have a large storage tank. Instead, it heats water on demand. Tankless heaters can rapidly produce hot water using high-powered elements. As a result, you will never run out of hot water.

Other hot water heater buying guides might recommend a tankless water heater from the get-go. However, we’re here to tell you that tankless heaters are not for everyone.

For example, if you live in a climate that is cold most of the year, a tankless water heater is likely not for you. The biggest downfall of a tankless heater, however, is that it costs significantly more to purchase and install. In fact, a tankless heater can cost up to three times as much as a traditional hot water tank (when comparing a low-quality traditional tank with the newest tankless unit). As well, cold temperatures (like that during an Edmonton winter) can be hard on tankless heaters. These drawbacks shouldn’t be overlooked by a hot water tank buying guide.

IMPORTANT NOTE: The notion that tankless water heaters don’t work in cold climates is more dependent on the type of tankless heater. Gas tankless water heaters tend to do well in Edmonton’s colder climate. However, electric tankless water heaters can have trouble keeping up in the cold. For this reason, ProSolutions Inc. provides and installs gas tankless water heaters in Edmonton homes.

If a tankless heater is right for you, it can have many benefits over traditional hot water tanks, including:

• Longer lifetime (in many cases, double the life of a traditional heater)
• Unlimited supply of hot water
• More energy efficient
• Lower utility bills
• Less space required

Are you considering buying and installing a tankless water heater? Below, we’ll discuss more about how to choose a tankless water heater.

What to know when buying a hot water heater and important factors to consider

To choose the perfect water heater for your home, there are a few important aspects you’ll need to consider. Here’s what to look for when buying a water heater.

• Size
• Efficiency
• Costs
• Tank type (if you decide to purchase a tank water heater)

Here’s what to know when buying a hot water heater when it comes to sizing, efficiency ratings and initial and long-term costs.

Size

When purchasing a new water heater, you’ll want to ensure that it’s big enough to meet your hot water needs. Selecting the proper size will also maximize the efficiency of the unit.

Ultimately, the size will depend on the amount of hot water you use. Therefore, the number of people in a household is often used to determine size requirements. Keep reading our hot water heater buying guide for size recommendations based on average household sizes and water usage. 

Keep in mind, however, that each household is different. You may have a hot tub or several showers with rain heads, meaning you’ll use more hot water than the average household. Working with a professional Edmonton plumbing services provider is, therefore, the best way to determine what size of water heater your household requires. This will ensure that your water heater isn’t too small, causing you to run out of hot water, or too big, resulting in more energy consumption and higher utility bills.

The size recommendations below are for traditional hot water tanks.

While the size of a traditional hot water heater is measured in litres or gallons, the size of a tankless water heater is expressed in GPM. GPM stands for Gallons Per Minute and represents how much water your tankless heater can heat in one minute.

GPM recommendations based on family size can be found here – How big should my tankless water heater be?

Efficiency

Are you looking to reduce your carbon footprint? There are many energy-efficient hot water heaters on the market today. Unfortunately, these heaters often come with a steep price tag. However, it’s important to keep in mind that although a more efficient water heater costs more upfront, it will save you money in the long run.

The efficiency of a gas-powered water heater (tank and tankless) is rated using the unit’s energy factor (EF).

What is the energy factor? 

EF = hot water produced / amount of gas used (in 24 hours)

That is, a water heater’s EF is calculated based on the amount of hot water produced divided by the amount of gas used within 24 hours.

The higher the EF, the more efficient the water heater.

The efficiency of electrical hot water tanks, on the other hand, is measured by standby loss (in watts).

What is standby loss?

Standby loss measures the amount of heat loss from the tank. The lower the standby loss, the more efficient the hot water heater.

Hot Water Heater Buying Guide Efficiency Rating Update

There’s a new efficiency rating in town! The U.S. Department of Energy introduced a new efficiency rating that now replaces Energy Factor (EF) in Canada. 

This new rating is referred to as Uniform Energy Factor or UEF.

What’s the difference between UEF vs EF? The two ratings do not differ in what they measure (i.e. the energy efficiency of gas hot water heaters). Instead, the difference between EF and UEF is the testing methods. The test procedure for UEF is meant to make it easier for homeowners to compare water heaters and to choose the right one. In addition, this new testing method better reflects how hot water is used in homes in 2025.

To determine a water heater’s UEF rating, it is first assigned to one of four bins, or categories, based on hot water usage. Then, the water heater’s performance is evaluated compared to the other units in that bin. For this reason, UEF comparisons can only be made between water heaters within the same bin. For instance, a high bin water heater with a UEF of 0.95 won’t perform the same as a low bin water heater with the same UEF. 

Like EF, the higher the UEF value, the more efficient the water heater (compared to other water heaters in the same bin).

To determine how efficient a given appliance is, look for its EnerGuide label. This label can be found on the appliance and in its product literature. The label will show you the appliance’s UEF. EnerGuide labels can also help you compare the efficiency of units that fall within the same bin – so you can decide which is right for your home.

A comparison of the old EnerGuide labels (using EF) and new labels (using UEF) is shown in our hot water heater buying guide below.

How to Choose the Most Efficient Water Heater

When looking for the most energy-efficient water heaters, look for an ENERGY STAR symbol. Products that have this symbol meet or exceed energy efficiency requirements set out by the government.

To be awarded an ENERGY STAR label, the following efficiency ratings must be met:

• Gas water heaters:
  
  
  • With tank volume greater than 20 gallons (75 L) and less than or equal to 55 gallons (208 L) – Medium draw: UEF ≥ 0.81; High draw: UEF ≥ 0.86
    
    
  • With tank volume greater than 55 gallons (208 L) – UEF ≥ 0.86
    
    
• Gas tankless water heater:
  
  
  • UEF ≥  0.95

Initial Costs vs Long-Term Costs

Before making your purchase, you’ll also want to consider the upfront and long-term costs of different types and models.

For example, some water heaters, especially highly efficient models, can be very expensive to buy and install. High-efficiency tankless heaters, in particular, can cost up to three times more than a less efficient, traditional heater (when comparing a low-end traditional tank with a new tankless heater). However, these models will save you money in the long run by cutting down your energy consumption. Also, their lifespan is much longer. Therefore, you’ll want to consider the pros and cons offered by a more expensive model before making your decision.

Maintenance costs should also be considered when evaluating the long-term costs of owning a hot water heater. Like any appliance, both tank and tankless hot water heaters require regular home maintenance. For example, the following annual maintenance is recommended: 

• Pilot assembly cleaning
• Inspection of flame sensors, thermocouples, and drain valves
• Tank flush

Although this annual maintenance will increase long-term costs, preventative upkeep will extend the life of your water heater and help minimize unexpected (and expensive) repairs.

Type of Tank

There are three main types of tank water heaters to choose from when buying a hot water tank. 

1. Atmospheric
2. Power Vent
3. Power Direct Vent

Each tank type has advantages and disadvantages. The type of tank you choose will also affect the upfront price and long-term operating costs of the unit.

Atmospheric

Atmospheric tanks, also known as conventional or natural draft tanks, are the most common type of gas hot water tank. They operate via natural convection, relying on the buoyancy of hot water to rise as cooler water enters from the bottom. Atmospheric tanks have a vent pipe positioned vertically or sloping upwards so the rising hot air can exit. Although typically more affordable upfront, their energy efficiency tends to be slightly lower, leading to higher long-term operational costs compared to other types of water tanks.

Power Vent

Power vent tanks overcome atmospheric tank limitations using a powered venting system to expel combustion gases. These tanks force exhaust gases out through a vent pipe with the help of a blower fan. Power vent tanks are more flexible in terms of installation locations since they don’t rely on natural draft and can vent horizontally or vertically through sidewalls or roofs. These types of tanks also harness exhaust heat to warm water, enhancing energy efficiency and savings. In addition, lower exhaust temperatures allow for PVC piping, a cost-effective alternative to the standard metal venting used with atmospheric tanks.

Power Direct Vent

A power direct vent tank draws combustion air from outside the home. This enhances efficiency and safety by minimizing the risk of backdrafting and indoor air contamination. Like power vent tanks, this type of tank uses a blower fan to expel combustion gases through a vent pipe. Power direct vent tanks are ideal for spaces with limited ventilation, ensuring safety and improved indoor air quality. In addition, PVC piping can be used with power direct vent water heaters to reduce installation costs.
