If you own a condensing tankless water heater, your installer should have included a drainage system to drain your water heater.Don’t worry, it’s not leaking, but rather undergoing a normal process called condensation, and Noritz makes the removal process easy with its condensing tankless models.
Does a non condensing tankless water heater need a drain?
The excess heat that is not transferred to the water is expelled through the exhaust venting. This exhaust is higher temperature than on a condensing tankless heater to lessen the risk of corrosion. However, non-condensing heaters generally require metal exhaust venting to withstand the higher temperatures.
Can you install a tankless water heater on an interior wall?
Electric tankless water heaters are designed to be installed indoors in the garage, basement, or interior wall. Both natural and propane gas tankless water heaters have indoor and outdoor models. Indoor models can also be installed in the garage, basement, or the exterior wall’s interior side to provide venting.
What is the difference between non condensing and condensing?
What Are the Differences Between Condensing and Non-Condensing Boilers? The main difference is that condensing boilers are up to 99% efficient while non-condensing boiler are only up to 78% efficient.
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.
Do tankless water heaters produce condensation?
Condensing Tankless Water Heater: A Condensing Tankless Water Heater extracts heat from the exhaust gases and produces gases around 100 degrees. These cooled gases produce condensation inside the water heater.These gases cool outside of the water heater.
What is water heater condensate?
Condensate is the result of airborne water vapor being chilled below the dew point. The dew point is the temperature at which water vapor turns into a liquid. Low incoming water temperatures cool the piping and the heat transfer surfaces of the water heater.
How much condensate does a heat pump water heater produce?
Moisture or condensation can be a by-product of the GeoSpring Hybrid electric water heater depending on humidity and the run time of the heat pump. Condensate amount will vary according to these conditions (approximately one to two quarts per day).
Can PEX be used for condensate drain?
You could use PEX tubing or Vinyl, but you need to make sure that it does not get kinked in any way and that it has a large enough ID to accomadate the flow of water or you will be asking for trouble. Also make sure that you are allowed to tie into the main drain line.
Why is my Rheem tankless water heater leaking?
A tankless water heater can develop leaks inside the heat exchanger.If the tankless water heater doesn’t properly vent out exhaust gases from the heat exchanger, it can cause the heat exchanger to corrode, and this can be potentially harmful to your house.
Why is my tankless water heater dripping?
If your tankless water heater is leaking, you may have one of the following problems: Sediment buildup. Improper venting (only in gas units) Faulty water pipe connections.
Can I put a tankless water heater in a closet?
Your tankless water heater can be installed just about anywhere! Due to the small size of your water heater, it can be mounted in many small spaces, including closets, under sinks, in pantries, or under stair storage areas.
How close can a tankless water heater be to an electrical panel?
The only code requirements I’ve found regarding clearances around an electrical panel are allowing at least a 30″ working space (side to side).
Where should a tankless water heater be installed?
The ideal location for your water heater is inside the home. Most installations are small and unobtrusive so they will easily fit in a pantry, under the stairs, or under your sink. If you must place the water heater outside, make sure it’s safe from direct sunlight, rain, and insects.
Does Rinnai make a condensing tankless water heater?
Rinnai condensing tankless water heaters come from the “Ultra” series, a series of the most advanced and efficient models.
What type of vent does a tankless water heater use?
Tankless water heaters can be vented in two ways: power-vent or direct-vent. Power-vent units use indoor air for combustion and simply vent the exhaust to the outside. Direct-vent units pull in air from the outside, so they have two vents for intake and exhaust.
Navien is a solid choice when it comes to tankless water heaters. Their units are manufacturered by a company that takes pride in quality, design, and user friendliness. In fact, there’s no shortage of satisfied customers!
Are electric tankless water heaters condensing?
Electric tankless water heaters are priced similarly to natural gas tankless water heaters. They are also comparably efficient to condensing tankless water heaters, and do not have the same venting issues that gas water heaters do.
How many gallons per minute do I need for a tankless water heater?
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. To find the correct capacity, add up all of the fixtures that you expect to use at the same time.
Are condensing hot water heaters worth it?
The thermal efficiency of a condensing storage water heater typically exceeds 90% far better than your current conventional tank, and it avoids some of the problems that tankless systems may have.
Why is the insulation in my water heater wet?
A fitting leak on the outside can cause premature failure, as water collected on top of the water heater can soak the insulation, and once that gets wet, it doesn’t dry out. It stays wet.
