Noritz Water Heater - Review of Tankless Appliances
Noritz
heating
company carries a variety of gas operated on demand water heaters that
are
environment friendly and using the advanced, green technology. They
also put an emphasis on energy and space conservation and
production of high efficient tankless appliances that are Energy Star
recognized.Using the finest and superior technology, Noritz instantaneous or on demand water heaters are producing hot water with 83-94% thermal efficiency, which means more savings on energy and money for you, when comparing to standard or conventional units.
Easy installation
Noritz on demand, natural gas and propane gas appliances can be installed virtually anywhere (there are restrictions also); saving you lots of space with wall mounting installation. As they are eco-friendly, they emit less greenhouse gases like CO2 and NOx. Models are combustion sealed and have a great advantage over atmospheric units as they are not using the internal air for combustion.Advanced features
Another great benefit for Noritz tankless water heaters is the longevity; so less waste goes into the landfills than tank type, units are also smaller, more durable and with the high percentage of recyclable materials. Since every heater's part is replaceable there is no need to replace the whole unit when there is a malfunction; replacing the damaged part is enough.The advanced condensing Noritz water heater units are using superior and greener technology, while taking the advantage of available latent heat and with a condensing process they are providing terrific 93% of thermal efficiency.
All water heater units are over 82% energy efficient and therefore Energy Star qualified with significant reduction in pollution.
Like any other water heating tankless manufacturer, Noritz on demand models are providing an endless and instant hot water. Noritz water heater is designed to be safe, to protect you and your kids from sudden burns, thanks to the electronic system called Advanced Q Function.
Available units are with the capacity and power output enough for one to five bathroom houses. If you need even more power and hot water, there is an option to link up to 24 units using a Multi-System or Quick-Connector.
All Noritz tankless hot water heaters are using minimal electricity; mainly to light the gas burner with the electric direct ignition, to power the vent and PC board which controls the system.
Simple troubleshooting
With a PC board and smart technology error codes are used to detect what is wrong with the unit.The common problem with any water heater is sediment buildup inside the copper piping and heat exchanger. Noritz recommends three solutions:
- Flushing the tankless unit periodically
- Installing a water softener
- Use ScaleShield to prevent from forming
Noritz Water Heater - Main Features
Every Noritz tankless model has a TurboFlow that allows the unit to meet any hot water demand, especially in the summer when the incoming water is warmer and when the heater automatically boosts its output to provide more flow capacity.
Noritz gas appliances are the only products of all manufacturers that are using Dual Flame Burner. This dual principle element utilizes the latest combustion technology that is electronically controlled and therefore provides hot water with very low temperature fluctuation, maximizing the heat output and maintaining high efficiency.
Dual flame burner technology uses two rows of burners, where second one burns the unlit gases escaped from the first row burners, so the result is an increased output efficiency, stabilized (less fluctuations) hot water temperature and increased performance; (not available on the N-0531S (new NR66-SV) and N-0631S (new NR71-SV) models).
Above the gas burner, water is heated in a commercial grade heat exchanger that is built from thick commercial grade copper piping, making it tougher on stress and even more durable.
With resin-coated PC board and on-board memory chip that stores the error code history maintenance and troubleshooting are very easy to do.
Noritz condensing water heaters are performing so well because of its advanced design. Condensing units feature a dual heat exchanger that combines stainless steel and copper heat exchanger.
The stainless steel component is designed to use the residual heat from the exhaust gases to preheat the incoming water before it runs through the main copper heat exchanger. The result is a significant reduction of carbon dioxide and the increase of the heater's efficiency to over 93%.
New 2009 models; N-0841MC (NCC199) and N-0842MC (new NRC111) are the only available condensing water heaters.
