If you are considering switching over from a tank water heater to a tankless one, or you are making decisions for a newly constructed home, it's important to know about both the benefits and the disadvantages of a tankless water heater. Whether you choose a traditional hot water heater, or you decide on a tankless gas or electric system, will depend on your budget and your current water heating needs.
The Initial Cost of a Tank vs. Tankless Water Heater
A tankless water heater is roughly three times the cost of a traditional tank water heater, a factor that makes the decision easy for many homeowners. If your budget does not have enough money in it to allow for a tankless water heating system, a simple tank water heater will be fine. While the tankless system will save money on heating costs over time, the savings are not significant enough for most people to make the switch from a tank system to a tankless one.
Tankless Systems Never Run Out of Hot Water
If you have a number of people living in your home who enjoy hot water showers and baths, a tankless system is perfect for your needs. This type of system does not run out of water, as water is heated on an as needed basis. A traditional water heater using a tank will eventually run out of hot water, creating the need to wait until the tank fills up again to enjoy hot water.
Other benefits of a tankless hot water tank include:
- Many come with a federal rebate that will give you cash upon installation.
- The systems generally last 5 or 10 years longer than a traditional tank system.
- The system won't flood, as there is no tank to rupture.
- You can control the unit by remote control in most cases.
- No greenhouse gases are created when the electric model is used.
- Tankless systems don't require as much space, and can be placed in inconspicuous places.
Here are some disadvantages associated with the tankless hot water tank :
- If you are using natural gas, you may need a larger line to provide enough gas to heat your water.
- They are more expensive than tank units.
- Electric models are not energy saving, and gas models produce greenhouse gases.
As a homeowner, you will have to decide whether you want hot water on demand, or you are willing to take the chance that your hot water tank is going to run out of water. Weigh the pros and cons of both styles, and come up with a choice that works best for your family.
