Condensing Vs Non Condensing Hot Water Heaters

The condensing tankless gas water heater venting is more straightforward than the non condensing opponent.

Condensing vs non condensing hot water heaters.

In the end it still depends on the venting system if you re going to install a condensing non condensing tankless system. In addition cheaper ventilation materials can be used because the temperature of exhaust gases is around 100 f. How it works rheem condesning tankless water heater. They also produce more hot water at a more.

Condensing tankless water heaters. That s why condensing water heaters are more efficient than the non condensing ones. Energy efficiency is amazing it can go up to 98. Non condensing tankless water heaters.

Since the heat from the steam is recycled you lose a lot less heat in the process. Non condensing units have efficiencies around 80 meaning around 20 of the heat is wasted and exhausted. To counteract this stainless steel alloys are generally the best choice when choosing a condensing water heater. This type of tankless water heater which heats the water by the gas burner and since the gasses are vented right away.

What s the difference between condensing and non condensing tankless water heaters. Compared to condensing water heaters that vents exhaust gasses inside the unit non condensing will immediately vent the exhaust gasses outside. In fact traditional non condensing tankless water heaters lose about 20 of their heat out the exhaust vent. The act of condensation results in several components having a shorter lifespan.

Corrosion is one of the biggest concerns with a condensing tankless water heater. Heating water accounts to about 30 of the average homes energy budget. Tankless water heaters only provide hot water when needed saving you 40 on your energy bill. 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.
