In the unlikely event that the upper part of this article has not been helpful enough in addressing any queries you may have about Noritz tankless water heaters to be more specific, here are some of Noritz’s most frequently asked questions to help you out;
How many Noritz tankless heaters do I need for my home?
Noritz manufactures different tankless water heaters with variance in size and thus heat capacity ranging from 6.6 gallons per minute to 13.2 gallons per minute. Basically, you need just one Noritz tankless water heater so long as it’s the right size depending on the size of your home and thus the gallons of heated water you would need per minute.
Can I install a Noritz tankless water heater in a mobile home?
Yes, you can if you get yourself the Noritz Direct Vent and outdoor tankless water heater models.
How much can I expect to save on my monthly bill?
Given the tankless water heater technology that applies the use of gas to heat water on demand you get to save up to half the initial energy and hence cost of heating water within your premises.
Can I use my existing venting for Noritz tankless water heater?
No, you cannot, because tankless water heaters are required to be Category III stainless steel venting to prevent corrosion from the slightly acidic condensate that forms during combustion.
Do I need to upgrade my gas line?
Yes, you do since tankless water heaters need relatively larger gas lines given their higher BTUs. The gas line upgrade will be determined by the tankless water heater model that you choose.
Why do I need electric power?
Even though the Noritz tankless water heaters strictly use natural or propane gas they are designed with digital remote applications, and PC boards that need the electrical power as a fundamental aspect of their functioning. Their electrical consumption is however very minimal.
How long do Norizt tankless water heaters last?
Noritz tankless water heaters are quite durable having been tested and proven through very rigorous quality control tests. Also, all tankless water heater parts for Noritz products are replaceable.
Will I get instant hot water with a tankless water heater?
No, you will not. Unlike what most people mistakenly think a tankless water heater will take around the same time as a tank water heater to heat the water through your plumbing system. However, this can be alleviated by hooking up your tankless water system with recirculation pumps.
Which recirculation pumps does Noritz recommend?
Noritz recommends the following recirculation pumps that keep full warranties;
- ACT/Metlund® Hot Water D’MAND® S-70T
- ACT/Metlund® Hot Water D’MAND® S-02T
- Taco D’MAND pumps 008-DM-P
- Taco D’MAND pumps 0011-DM
