Hot Water Tanks

Standard hot water heaters are more economical, with a lower up-front cost compared to tankless. They can accommodate steady, high-use demand. Hot water tank heaters are also commonly known as conventional water heaters, or CV Tanks. Capacity of hot water tanks are measured in gallons. The capacity of traditional CV tanks is usually in the range from 20 to 100 gallons, and the most popular sizes are 40, 50, 60 and 80-gallon tanks as they produce enough hot water for the family sizes of 4-6.

Over time a hot water tank will begin to develop sediments, these sediments will then find a home at the bottom of your hot water tank. When the hot water is required these sediments then begin to mix into your water supply. The average hot water tank has a lifespan of approximately 10 to 13-years depending on how hard your water is.  

As the years go by sediments and calcification begin to form a layer at the bottom of your hot water tank and begin to get thicker and thicker. As hot water tanks are heated from the bottom up, they need to work hard to get through this build up over the years. Good quality hot water tanks such as John Wood - AO smith and Bradford White are built with a glass liner unlike some other units that have a metal liner where the water is corrodes and rusts the metal over time and leaves these sediments in your tank.

Power Vented Tanks vs. Conventionally Vented Tanks​

Power vented water heaters are one of the most used gas water heater used on newer houses, it is a storage tank type water heater consist of a gas burner and a steel cylinder with insulations to store hot water. A power vent water heater does not require access to a chimney, it uses an electrically powered fan to move combustion products outside. And requires and electrical outlet near the tank.

When to select a PV Tank:

  • Upgrading an electric water heater with no ready access to a chimney

  • Dedicated access to an electrical receptacle within six feet of the unit

 

Conventional vented water heaters are one of the most used gas water heater used on older houses. A conventional vent is required on most standard natural gas water heaters. Conventional vents can be either type of a double-wall metal vents or a tile-lined brick chimney, a chimney liner is by-law required in Canada for safety concerns. A conventional water tank does not require an electrical outlet near the water tank for installation. And it does not require electricity. If there is a power outage you will still have hot water.

Direct Vent:

In a direct vent water heater, fuel is burned and the heat from the combustion process is used to heat the water. The exhaust gases are then transferred to the outside of the home via the exhaust pipe or chimney.

Direct venting works because the heated air is lighter than cool air and in turn, will rise naturally due to the difference in buoyancy between the hot and cold air. This is a simple system that works well when the exhaust gases can be vented vertically. No extra power is needed and in turn, the overall hot water heating costs are lower.
