As the technology of tankless and on-demand water heaters has improved, more and more people are considering tankless as an option in their home. They are a bit more expensive than their more common counterparts, but far more energy-efficient and less invasive (taking up much less space). Figures from the U.S. Dept. of Energy indicate that a tankless water heater is about 30 percent more efficient than a tank-style heater in homes using less than 41 gallons of water per day.
On-demand units don’t yet have the lifespan to match their predecessors and with more moving parts, they can cost more in maintenance and replacement. In short, there are pros and cons to owning either design. Whether you should make the switch will depend on your usage, expectations and budget.
The Cost of Energy
Tank-style water heaters apply a low level of energy to keep a large volume of water heated and ready for you when you need it. Since the insulation of the tank is not perfect, a low level of energy—by way of electricity or gas—is applied to offset the loss and maintain the hot water.
Tankless models on the other hand apply a large amount of energy when called upon. In doing so, they do not expend excess energy compensating for heat loss, meaning they’re more efficient.
Of course, this efficiency doesn’t come without a price. You’ll pay more upfront for a tankless heater. They also cost more in upkeep, maintenance and still have a shorter average lifespan than tank models. Of course, the idea is that you’ll recoup your losses over time in energy savings, and while this is generally true, it’s not the case for everyone.
What You Should Know
There are a few things you’ll want to consider before you make the switch to tankless.
It’s a good idea to consult a licensed plumber, who can install the unit or help you select a tankless water heater setup that works for your needs.
