The Best Tankless Water Heaters for Endless, Luxurious Showers
If you’ve had enough of running out of water during your shower, or if you just know it’s time to replace your old hot water heater, you might be thinking of upgrading to a tankless hot water heater. Understanding a little bit about what sets tankless models apart from older tanked versions along with their possible limitations can make you feel more confident when you begin comparing models to find the one that best meets your needs.
The first thing to understand is that tankless water heaters will not ever run out of hot water, but too many applications running concurrently could make it impossible for the heater to keep up, resulting in a loss of hot water pressure. The other misconception that many people have is that tankless heaters eliminate the need to wait for hot water at all of your faucets. In fact, how long it takes hot water to get to a faucet doesn’t have anything to do with the kind of water heater you have. Instead, this depends entirely on how far away from the hot water heater your faucet is located. A tankless model can’t make water travel through your pipes any faster than a tanked model can. If you want instant hot water, you’ll need a point-of-service tankless heater installed at each of the faucets where you desire instant hot water. These point-of-service units work in the same manner as whole-home tankless water heaters (but smaller), so keep reading for more details about the advantages of tankless systems.
Old-fashioned water heaters all rely on a tank for water storage. That water gets heated to a temperature of your choosing. When you use water, more water is pumped in and has to be heated. If water sits in the tank for too long, it slowly cools, which results in the heating process restarting. This means that you’re spending money to heat and reheat water that isn’t being used when you’re at work, asleep, or out of town. Also, since these tanks can only hold so much water, too many hot water applications going at once could result in all of the hot water being used, leaving somebody in the cold until the tank refills and reheats.
Tankless water heaters, as the name implies and as you’ll find out on tankless.reviews, don’t rely on a tank for storing heated water. Instead, water is instantly heated as it passes through the heater. This saves energy and money because there’s no constant heat-cool-reheat process happening. It also means that there’s no tank to empty, so there’s no running out of hot water, which means you don’t ever have to worry about getting to the shower first. Another advantage to tankless heaters is that there’s no worry about the tank rusting, leaking, or bursting, resulting in potentially significant water damage in addition to a major mess.
As mentioned earlier, tankless heaters can’t process an unlimited amount of water all at once, which means that you might not be able to run all of your hot water taps at once without losing water pressure. Different tankless models are rated to handle different amounts of water. A tankless heater’s capacity is measured in gallons per minute (GPM). More GPM equals better water pressure for more concurrent applications. As a point of reference, faucets and showers usually flow at a rate of somewhere around 2.2 GPM to 2.5 GPM. If you like washing clothes in hot water or use a dishwasher that doesn’t have it’s own hot water source, you’re looking at 2 GPM to 3 GPM. These guidelines can help you determine your ideal GPM level for the tankless model that will meet your needs. It’s also possible to install multiple parallel-running tankless heaters to increase the amount of hot water that can be delivered.
Tankless hot water heaters, especially the point-of-service models, do cost more than traditional tank models. Keep in mind, though, that you’ll be able to recoup this cost on your energy bill by not having to pay for the heat-cool-reheat cycle. The extra added cost of point-of-service setups can be offset through less water wasted while you wait for it to get hot. View this for recommendations on electric tankless water heater brands.
