Tankless heaters vs. storage heaters: energy efficiency

If you told a plumber you were installing a storage water heater to save energy, they’d probably look at you funny. Storage tank water heaters are bought for many reasons, but energy efficiency is far from one of them. Traditional storage water tanks waste 40 to 50 percent of the fuel they burn. But for all that wasted energy, the water stays hot for hours, right?

Wrong! Storage tank water heaters heat up and cool down regularly, and this is largely why they’re so bad on energy costs. Moreover, most of these heaters run on natural gas, propane, or fuel oil, and all these fuels are expensive, dangerous, and harmful to the environment.

Advantage: Tankless

Tankless water heaters, on the other hand, are great on energy, and they run on electricity so you don’t have to worry about gas- or propane-related hazards. These systems use a coil to heat water, so there’s no waste from gas or oil use. The Department of Energy has found that 17 percent of energy use in the typical American home is linked to heating water, and across the U.S. homeowners routinely pay high energy bills.

A system that saves energy is a system that saves money, and this truth is one that leads many homeowners to go with a tankless water heater installation. You may also qualify for a rebate if you purchase one of these electric tankless water heaters.

Tankless heaters vs. storage heaters: Affordability

Affordability is an important aspect to consider when choosing a water heater, and you must decide how much you’re willing to spend before selecting an option. While tankless water heaters typically cost more than storage tank water heaters up front, they are designed to be more affordable in the long run.

Consider the following points when trying to decide which is a more affordable option:

  • Electric tankless water heaters cost around $500 whereas storage tank water heaters cost around $1,000.
  • Using a tankless heater throughout the year will cost less than using a storage tank water heater over that same period.
  • Storage tank water heaters are generally much larger than a tankless water heaters, so you may have to spend on creating an installation space. Tankless heaters, on the other hand, can be mounted on the wall to take up very little space.
  • Storage heaters typically run on expensive combustive fuels, whereas electric heaters run on a more sustainable form of power.

Advantage: Toss up

One must also account for risk, as well as for costs that could arise should something go wrong. A gas- or oil-related fire is a lot more costly than an electrical malfunction, and electric tankless heaters don’t pose the risk to life and limb that traditional storage heaters do.

Tankless heaters vs. storage heaters: Usability

Conventional storage tank water heaters have been popular for a long time, mainly because using these systems is not too difficult. It’s when things go wrong, however, that storage heaters reveal their inherent complexities.

For example, realizing that a storage heater is not working usually requires an annoying event, a cold shower for example. Then once the problem is detected, attending to it isn’t always straightforward; in most instances you’ll have to get a professional plumber over to help.

Advantage: Tankless

Electric tankless water heaters are designed with efficiency in mind, and this is largely why they’re so user-friendly. Operating one of these systems does not require a lot of thought, and they’re very good at alerting you of potential issues before it’s too late. Moreover, most tankless water heaters being made today have smartphone-enabled technology inside, and such systems are taking usability to a whole new level.

Tankless heaters vs. storage water heaters: Reliability

Hot water is often a necessity, and most people will tell you there are few things worse than having no hot water during a pre-work morning shower. Reliability is a word often associated with tankless water heaters, and these systems, with their on-demand access to controlled hot water, are installed by an innumerable amount of homeowners specifically because they’re so good at never letting users down.

Storage tank water heaters are reliable systems as well, though their reliability comes at some high costs vs tankless water heaters. You shouldn’t have to spend an arm and a leg, designate a large amount of room, and take on a lot of risks just to heat the water in your home. It’s 2019, and reliability now comes with, not at the cost of, affordability and eco-friendliness.

Advantage: Tankless

There's no doubt about it - tankless water heaters get the nod over storage tank water heaters when it comes to reliability.

Tankless heaters vs. storage heaters: Maintainability

Affordability and usability are the aspects that’ll come to mind first when you’re deciding on which water-heating system to purchase, but you shouldn’t forget about maintaining the system and all the elements associated with it. Maintaining storage water heaters is said to be simple, but many owners of these systems think otherwise after a few problems occur.

When it comes to maintenance, tankless electric water heaters are preferred over traditional storage water heaters. Maintaining these systems is not only cheaper, but maintenance only has to be conducted once a year in order to ensure everything is running at optimal conditions. And if you need to find professionals for a tankless water heater installation, finding reputable and certified electricians is not difficult.

Advantage: Tankless

If you value easy maintenance, go with a tankless water heater.
