What is the difference between condensing and non-condensing?
The steam or vapour cools and condenses on a surface. The condensation water is acidic and will corrode all kinds of common home appliance materials. A non-condensing tankless water heater will vent these hot byproducts, which cool down outside the unit.
Is condensing better than non-condensing?
The main reason why condensing boilers are better than non-condensing models is that they are at least 25% more efficient. By reaching up to 99% efficiency, condensing boilers can help you lower your fuel bills significantly and reduce your carbon footprint, making them a great alternative heating system.
Are condensing tankless water heaters worth it?
Condensing tankless water heaters save more money by recycling their byproducts to produce extra heat. Depending on how you’ve connected the condensation line, this byproduct can potentially be recycled back into your water lines, thereby reducing your water bills (slightly).
How do you vent a non-condensing tankless water heater?
Tankless water heaters can be vented in two ways: power-vent or direct-vent. Power-vent units use indoor air for combustion and simply vent the exhaust to the outside. Direct-vent units pull in air from the outside, so they have two vents for intake and exhaust.
How does a non condensing tankless water heater work?
Non-condensing technology utilizes a single heat exchanger to heat the water to the desired temperature. Water flows through a heat exchanger where it is heated to the desired temperature by the hot exhaust gases. The excess heat that is not transferred to the water is expelled through the exhaust venting.
Does Rinnai make a condensing tankless water heater?
Rinnai condensing tankless water heaters come from the “Ultra” series, a series of the most advanced and efficient models.
What is the meaning of non condensing?
adjective. 1Not involving the condensation of steam; specifically designating a steam engine in which the steam on leaving the cylinder is not fed into a condenser but is either reused in some other way, or discharged into the atmosphere. 2That does not undergo or cause condensation.
Do tankless water heaters need to be vented outside?
Installing a tankless water heater outside frees up indoor space and requires no additional venting. Traditional gas tank water heater require venting through the roof. Tankless water heaters use fans to blow exhaust from the unit horizontally, allowing vents to terminate on the side of a house.
How long will a Rinnai tankless water heater last?
to 20 years
The life expectancy (or useful lifespan) of a Rinnai tankless water heater is up to 20 years. Actual life is impacted by water quality, usage and proper maintenance. For comparison, a tankless water heater lasts about twice as long as a tank water heater, making them a better value in the long run.
How does a condensing tankless water heater work?
Condensing Tankless Water Heaters extract the additional heat from the exhaust gases through various means and therefore exhaust cooler gases, usually around 100 degree F. As mentioned before cooling the exhaust gases produces condensation, in this case inside the unit.
What is humidity non condensing range?
Relative humidity is the percentage of the total water vapor that can exist in the air without condensing, and is inversely proportional to air temperature. The ambient relative humidity range of 45 to 50 percent is suitable for safe data processing operations.
