Pros and Cons of
A Tankless Hot Water Heater
There are some myths associated with on-demand hot water heaters
One is the expense of operation - regardless how you heat water; electric, gas or rubbing two sticks together it’s a measure of energy: It takes one BTU of energy to raise one pound of water one degree Fahrenheit. It's what you pay for that BTU that counts.
1. Tankless allow you to take two-hour showers and still save on electricity. If having unlimited hot water means taking longer showers then there will probably be less savings.
2. The water will come out of the faucet boiling hot as soon as you turn on the tap. Not exactly, but if you touch the water output at the heater you will feel heat within a few seconds.
3. Everything will be perfect - right out of the box - without any fine-tuning. Adjusting water intake and temperature controls down wil take care of most problems.
4. Can’t run two showers and wash a load of clothes at the same time. It's a different concept - if that is what you need then stay with a tank or be prepared to pay a lot for installation.
Then there are the buyers who didn’t do their homework and they’re mad at the manufacturer when in reality they bought a unit that was:
1. Too small for their needs.
2. Only suitable for an area with warmer ground water temperature than where they live.
But What A Tankless Hot Water Heater Does Offer:
1. An opportunity put it just about anywhere in the house you like.
2. Far more energy efficient - especially electric.
3. An electric tankless is cheaper and easier to install but may cost more in utility bills. But maybe not - compare rates befor you buy. (Larger sizes and older homes will require sub-panels)
4. Can take unlimited showers and clothes washing loads.
5. Waiting for hot water can be eliminated with an easy to install, point-of-use water heater.
6. Less likely to be an environment for bacterial growth.
7. A tankless water heater when coupled with an energy saving device will offer big savings. For many homes this could mean no electrical panel upgrade needed.
8. Less for the landfill and lower energy use - double bonus.
9. Can be adjusted to avoid scalding and paying for over heating.
10. No storage tank means less hard water problems.
