FAQ:

Q: Are tankless water heaters worth it?

A: Of course, tankless hot water heaters are worth it. They have a higher upfront cost, but a lower running cost and last twice as long as the conventional tank water heaters. You will find the full summary with calculated savings costs at the end of the article (we’ll calculate them using best rule-of-thumb estimations).

Q: What size tankless water heater should you buy?

A: Tankless or on-demand heaters for water are also called instantaneous water heaters. There is no need to use a storage tank for these types. A good choice would be 20 inches for its height, 14 inches for its weight, and 6 inches deep.

Q: How much electricity does an electric water heater use?

A: Electric water heaters are typically running for 3 hours a day to heat water, newer more efficient models may run for only half the time during each day. A typical water heater will use around 4000 watts.

Q: Does Rinnai make an electric water heater?

A: Unless you have a Rinnai recirculation solution, tankless water heaters do not produce instant hot water, but a Rinnai Tankless Water Heater does produce an endless supply of hot water.
