This reference article is focused on the electricity powered tankless systems. For gas powered tankless hot water heaters, please reference this page. We will help you understand the various features of the many types of water heating systems so that you can make a well-informed decision.
The Conventional Storage Tank System
Many homes today are built with a conventional hot water storage tank. This is the model most people think of and or decades, they were the systems of choice. They are still are a good choice depending on your needs and price point.
These systems consist of a large insulated storage tank, with capacities ranging from 30 to 80 gallons. It works by heating ALL of the water in the tank at once, providing it on demand and then heating fresh water as it comes into the tank.
Electric storage water heaters have usually two heater elements, much like you would find in a kitchen kettle, but much larger.
Electricity powered heaters, tend to be the least economical and most expensive to run when all other considerations such as size are factored in. This is based on the current energy costs. Natural gas is usually more cost efficient if it is already run to your home.
Sizing a Storage Hot Water Tank
When choosing a storage heater, base your requirements based on the table below.

Water Heater Recovery Rate
A water heater recovery rate measures how long it takes to heat up the entire tank of hot water. It’s normally expressed in how many gallons of water can be raised by a specific temperature in one hour. The higher the number, the quicker your water is heated. This is important if you have a large family and hot water is being used for showers in a short space of time.
The larger tanks take longer to heat the water up to the desired temperature.
This is one of the negatives of a storage tank system when compared to a tankless system, which effectively provides hot water on demand.
Storage Tank Size
New water heater regulations have been introduced by the Department of Energy, to increase maximum energy efficiency standards. The NAECA (National Appliance Energy Conservation Act) guidelines came into force in 2015. Dimensions will generally increase by 2 inches wider in both width and depth compared to previous heaters. If the location of your tank is somewhere that has plenty of space, then this is unlikely to present any problems. But if your current heater system only just fits into its current location then there are a couple of options available to you Once you discuss your situation with our expert plumbing team, we can either:
- Install a lower capacity storage tank system.
- Upgrade you to a tankless system.
- Try to find an alternative location for your new water heater
Tankless Vs Storage Tank System
When thinking about upgrading to a tankless unit, there are many factors to consider. Refer to the table below.
|Conventional Storage Tanks
|Hot water is available on demand – and shouldn’t run out
|Pre-heats and then stores hot water in tank – limited amount of hot water.
|Economical once installed- only heats the water you need
|Heats the entire tank of water, regardless of if its needed or not.
|Environmentally friendly – only heating what is required
|Not an intelligent or adaptive system therefore not as environmentally friendly.
|Longer life span 15- 20 years
|Shorter life span 7 – 13 years
|Potential space saving – no need for a storage tank
|Can require a lot of space.
|Higher installation costs.
|Cheaper to install.
|Can only cope with so many appliances running at once – washing machine, dishwasher, shower.

How Does an Electric Tankless Hot Water System Work?
Cold water runs through small pipes (usually made out of copper) through the heating unit.
Heating rods similar to those found in a storage tank variety rapidly heat up the water as it passes over those elements. There might be between one and four of these heating elements depending on the rate of hot water that is required. This produces a constant supply of hot water.
For the purposes of this article we are going to focus entirely on the electrical powered variety of tankless water heaters.
What Should You Consider When Buying a Tankless Hot Water Heater?
Water heating is responsible for approximately 20 percent of an average home’s energy bills. With the new tankless water systems you need to consider the Gallons Per Minute (GPM) rating. This is basically how many gallons per minute you can get continuous hot water. It is also worth noting, that physics does come into play here and every time an additional faucet, dishwasher or washing machine is being operated this will have a detrimental effect on the water flow rate. If that scenario is a regular occurrence in your household, then it may be worth considering two separate heaters. Prior to speaking with our plumbing experts, consider your personal household usage. To give you a reference point, here are some examples of hot water appliances and their average usage.
Due to the lack of a tank, the options now available for placement of your heater have drastically increased. Think about empty cupboards, or out of the way places where your heater can be installed, freeing up more valuable real estate. Once you have worked out where the heater will go this will assist you in choosing the most appropriate model. Our trained plumbers can also complete a site visit prior to installation, just to confirm the optimum location for both convenience and regulations. Also take into consideration the removal of the old tank, a service which our experienced and professional team will be happy to provide.
