Condensing Vs Non Condensing Hot Water Heaters

How it works rheem condesning tankless water heater.

Condensing vs non condensing hot water heaters.

They also produce more hot water at a more. As the end of the last section illustrated there are some serious efficiency advantages to using a condensing water heater. In fact traditional non condensing tankless water heaters lose about 20 of their heat out the exhaust vent. In addition cheaper ventilation materials can be used because the temperature of exhaust gases is around 100 f.

Heating water accounts to about 30 of the average homes energy budget. 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. It loses about 20 of the heat that helps the water become hotter. Since the heat from the steam is recycled you lose a lot less heat in the process.

The condensing tankless gas water heater venting is more straightforward than the non condensing opponent. Non condensing units have efficiencies around 80 meaning around 20 of the heat is wasted and exhausted. 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.

Corrosion is one of the biggest concerns with a condensing tankless water heater. Tankless water heaters only provide hot water when needed saving you 40 on your energy bill. Energy efficiency is amazing it can go up to 98. Non condensing tankless water heaters.

What s the difference between condensing and non condensing tankless water heaters. That s why condensing water heaters are more efficient than the non condensing ones. To counteract this stainless steel alloys are generally the best choice when choosing a condensing water heater. Condensing tankless water heaters also pose a lower risk for unwanted heating or safety related to fire.
