Frequently Asked Questions

Q: I’m a homeowner. Why would I want to go tankless over owning a conventional storage water heater?

A: There are many reasons why purchasing a tankless water heater is the way to go. First of all, tankless water heaters are simply more efficient (they are twice as efficient as a conventional storage water heater. Secondly, the lifespan – tankless water heaters can last more than 20 years (with proper maintenance) as opposed to storage tanks that usually last five to 10 years. Thirdly, you won’t run out of hot water (hence the alternative name, on-demand water heaters). You will have an endless supply of hot water whenever you need it. Lastly, tankless water heaters save space, time, and money in the long run. Overall, buying a tankless water heater is a win-win. 

Q: How much money does buying a tankless water heater save in the long run?

A: Since tankless water heaters are 50 percent more efficient than conventional water heaters, they save money in utility expenses. If you have propane or natural gas, your energy costs will drastically decrease your propane or natural gas consumption.

Q: What is the typical lifespan of a tankless water heater?

A: A tankless water heater lasts 15 to 20 years (or more). It is crucial to maintain your tankless water heater every year. You may have to replace a part of your tankless water heater every once in a while (similar to auto care).

Q: How long does it take to install a tankless water heater, and what is the process?

A: The entire process usually takes about four hours. We specialize in retro-fitting residential tank water heaters with tankless. In this process, we first pull out the water heater. Then we move the vent system from the ceiling (or, depending on the type of tankless water heater, we will install directly outside). We cannot use existing vents – we need to replace that with another one and screw the unit to the wall in order to run the gas lines and water lines to the unit.

Q: What type of hookups do I need in my home/place of business to have a tankless water heater installed?

A: They would be the same hookups that you’d need for a storage tank heater. You would need a hot water line, a cold water line, and a gas line. Sometimes, you will need to upgrade the gas size, but this is very rare. We would need access to vent it, whether through the ceiling or taking the vent off the top of the water heater and shooting it outside through an exterior wall. You would also need 120 watts for your energy. And that’s it!

Q: What is the best tankless water heater model, and why?

A: We exclusively install Noritz tankless water heaters because they are one of the best brands in the industry. Noritz Tankless Water Heaters has been one of the leading water heater manufacturers since the 1950s and provides exceptional quality and craftsmanship in its products. We recommend the EZTR tankless water heaters.

Q: Do tankless water heaters really provide constant hot water? Are there any exceptions?

A: Yes, tankless water heaters mean an endless supply of water. If there is a disruption in hot water, most of the time, it’s not related to the tankless water heater – it’s the tankless water heater reacting to a low flow of water. A tankless water heater needs a half-gallon of hot water to keep running. If you’re taking a shower or running a faucet – and not using a lot of hot water – the unit will turn off every so often. However, that’s an easy fix! The solution is to use more hot water. Thankfully this is not an issue with Noritz’s tankless water heaters.

Q: Does Arnett’s Water Systems offer any maintenance services for tankless water heaters?

A: Yes, we do offer maintenance and repair services. We also offer a membership program that provides discounts on maintenance services.
