Whether you're trying to save the planet or save money on your utility bills, it never hurts to invest in more efficient appliances. If your hot water heater seems to be on its last legs, then it may be time to consider an upgrade. While modern storage tank units can offer significant efficiency improvements, you can realize far greater gains by upgrading to a tankless unit.
Tankless water heaters may not be right for all budgets or situations, but many households will benefit from installing one. Keep reading to discover three reasons why a tankless unit can help to make your home more efficient and save you money.
1. Less Unused Hot Water
Storage water heaters work on a relatively simple principle: keep a large volume of water heated so that hot water is available when needed. This brute force approach solves the practical problem of providing on-demand hot water, but it comes with a significant downside. If you don't use the water in the tank, it will eventually cool down, essentially wasted the energy used to heat it.
Tankless water heaters only heat the water that you use. Ultimately, this means that you aren't burning fuel to heat a tank full of water that you will never use.
2. Less Time Spent Running
The loss of heat from a conventional water heater tank can waste water in other, more subtle ways, as well. Since your storage heater doesn't know when you'll need water, it must keep the water in the tank at your setpoint temperature. As the water cools, your water heater will turn on its burner to raise the temperature back to the appropriate level.
Since tankless water heaters only heat water on demand, they spend significantly less time running. Your water heater will run when you use hot water and stop running when you shut off the tap. This shorter duty cycle means that tankless heaters are more efficient and last longer.
3. Better Versatility
When you select a storage water heater, you need to choose a unit with sufficient capacity for your whole house. You can take the same approach with tankless heaters, but this can sometimes lead to demand issues. Instead, tankless heaters offer another option: you can install multiple units to serve individual rooms or fixtures.
While this approach can cost more upfront, it can offer significant energy gains. Point-of-use units only need to provide enough hot water for a single fixture at a time, allowing them to be smaller and more energy-efficient. This versatility means that you can design a hot water system for your home that perfectly matches your unique plumbing needs.
