Condensing Vs Non Condensing Hot Water Heaters

What s the difference between condensing and non condensing tankless water heaters.

Condensing vs non condensing hot water heaters.

To counteract this stainless steel alloys are generally the best choice when choosing a condensing water heater. Energy efficiency is amazing it can go up to 98. Non condensing tankless water heaters. This type of tankless water heater which heats the water by the gas burner and since the gasses are vented right away.

Tankless water heaters only provide hot water when needed saving you 40 on your energy bill. Non condensing units have efficiencies around 80 meaning around 20 of the heat is wasted and exhausted. Compared to condensing water heaters that vents exhaust gasses inside the unit non condensing will immediately vent the exhaust gasses outside. In addition cheaper ventilation materials can be used because the temperature of exhaust gases is around 100 f.

The condensing tankless gas water heater venting is more straightforward than the non condensing opponent. Heating water accounts to about 30 of the average homes energy budget. How it works rheem condesning tankless water heater. As the end of the last section illustrated there are some serious efficiency advantages to using a condensing water heater.

They also produce more hot water at a more. In the end it still depends on the venting system if you re going to install a condensing non condensing tankless system. Corrosion is one of the biggest concerns with a condensing tankless water heater. 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.

Since the heat from the steam is recycled you lose a lot less heat in the process. Condensing tankless water heaters. The act of condensation results in several components having a shorter lifespan. In fact traditional non condensing tankless water heaters lose about 20 of their heat out the exhaust vent.
