How much condensate comes out of a tankless water heater?
Although only a maximum of two gallons of liquid per hour is released, it will accumulate if improperly drained. Another consideration when draining condensate is the liquid’s acidity. “Water-heater condensate usually has a pH of two or three,” says Oshiro.
What is a good flow rate for a tankless water heater?
SELECTING A TANKLESS WATER HEATER
For a home with 1 bathroom, we recommend 6-7 GPM; 2 bathrooms, 8 – 9 GPM; and 3+ bathrooms, 9-11 GPM. In our experience, smaller 4-5 GPM units are suitable for studio apartments and small one bathroom homes or other application specific needs.
How many gallons per minute is good for a tankless water heater?
In a tankless system, water is heated only as it is needed. The best sizing factor for a tankless water heater is its flow per minute rate. A 3.2 gpm, tankless heater can heat 3.2 gallons of water per minute, which is roughly enough to provide hot water to a shower and a sink.
Is a condensing tankless water heater worth it?
Condensing water heaters are worth it due to their lower cost and increased efficiency compared to non-condensing heaters. Installing a condensing water heater will drive down your energy usage, contribute less to environmental degradation, and improve your water heating efficiency from 85% to 95%.

What is the advantage of a condensing tankless water heater?
A condensing tankless water heater can recycle that extra heat. It only vents the vapor when it is no longer useful for the heating process, and is known as a closed system. The vapor from a condensing tankless water heater is much cooler. Therefore it doesn’t require the same expensive and elaborate venting material.
Is condensing better than non-condensing?
Condensing and non-condensing boilers both burn fuel, such as gas, but the main difference is that the energy efficiency of condensing boilers is up to 99% efficient while non-condensing boilers are only up to 78% efficient.
Which is better navien vs Rinnai?
Navien Water heaters have an advantage when it comes to being energy efficient. Navien units have UEF ratings of up to 0.96 while Rinnai Units max out at approximately 0.93. The more efficient the unit is, the less energy waste which translates to more energy savings.
Do tankless water heaters need a drip pan?
A: Drain pans are not required for tankless water heaters at all. They are required for tank type water heaters located where a leak will cause damage to the building.
Are tankless water heaters less likely to leak?
If your tank gets a leak, that could cause a huge mess and a lot of water damage! Tankless water heaters don’t have that risk, since there’s no tank that holds water. A tankless water heater could only cause about as much damage as a leaky faucet, so you don’t have to worry about a catastrophe!

Can I use existing vent for tankless water heater?
Tankless units require 1/2″ or 3/4″ water lines and 3/4″ gas lines. Keep in mind that the new tankless heater cannot be connected to the existing exhaust pipe from your old heater. All tankless direct vent heaters require a stand-alone intake/exhaust system.
How do I insulate my tankless water heater in my attic?
