Condensing Tankless Water Heaters
The main advantages of tankless water heaters include:
New NPE-S2 Series
All the hot water you need, for as long as you need it.
CONDENSING AND NON-CONDENSING TANKLESS WATER HEATERS.
Condensing and non-condensing tankless water heaters differ primarily in how they handle exhaust gases and heat transfer.
Condensing tankless water heaters utilize a secondary heat exchanger to extract additional heat from the exhaust gases before they are vented outside. This allows them to achieve higher efficiency by capturing heat that would otherwise be wasted in non-condensing models. The captured heat is used to preheat incoming cold water, reducing the amount of energy needed to heat the water to the desired temperature.
On the other hand, non-condensing tankless water heaters do not have a secondary heat exchanger. As a result, they do not capture as much heat from the exhaust gases, leading to lower efficiency compared to condensing models. However, non-condensing tankless water heaters are typically simpler in design and may be more affordable upfront.
In summary, condensing tankless water heaters offer higher efficiency by capturing additional heat from exhaust gases, while non-condensing models are simpler and may be more budget-friendly.
