There are definitely more benefits to a tankless water heater than any potential disadvantages, so I’ll get the two cons out of the way. First and foremost, if your residence doesn’t have either natural gas or LP gas, and electricity is all that’s available, you can take tankless water heaters off of the table (unless you’ve already decided to add gas to your home). This can definitely be a frustration point when choosing a new water heater. Tankless water heaters that use natural gas or LP gas are the only effective option. Unless it’s a secondary getaway cabin that doesn’t get much use, we do not recommend electric tankless water heaters.
The other con is the sheer upfront cost of a tankless water heater. Of course, you’ll get a lot of benefits by investing in a tankless water heater, but it’s going to be one of the most expensive options. You’d have to factor in what you’re actually getting for what you’re spending upfront in order to justify the cost. With those two potential cons out of the way, let’s get into all the benefits you’ll experience by deciding to get a tankless system.
The small size of the system is one of the first benefits that comes to mind. A tankless water heater hangs on the wall, which frees up the space where a larger tank system would be. This is especially useful in an apartment or smaller residence where space is at a premium. (Some tank water heaters can be unusually large in size, too.) In the right situation, like in a closet, it can really make a big difference.
Next, the lifespan of a tankless water heater is nearly twice that of a tank water heater. Yes, it’s much more of an upfront cost, but it starts to pose a very attractive cost of ownership over its lifespan. Going from a 50 gallon electric water heater to a gas tankless water heater can actually save 70% on your electric bill. If running your tankless water heater would cost about $180 a year, an electric tank water heater would have definitely exceeded $600 a year (or more, based on age). It’s a big overall cost savings when you combine the total cost of ownership and overall efficiency.
One of the coolest benefits of a tankless water heater pertains to something we’ve all experienced at least once. Think back to the last time the hot water ran out and you had to take a cold shower. A tankless water heater provides endless hot water as long as you provide some kind of fuel and power. You can fill up a large soaking tub in one go, take a long shower, or let several family members take consecutive showers without running out of hot water. Those things might not have been practical with a tank water heater. It’s really great when you don’t have to wonder if you’re going to have to take another cold shower.
