Pentair ETi 400 High-Efficiency Pool and Spa Heater!

What is up ePoolSupply supporters! Back here today with you all to go over another What’s in The Box product manufactured by our beloved friends at Pentair. They make in our opinion the finest and most reliable pool equipment on the market, and I would love to discuss one in particular that sets the industry standard. Now I’m sure you all are familiar with pool heaters and how they operate as well as the different options out there but today we will be talking about one as it pertains to efficiency and the best bang for your buck. Today we will be discussing the Pentair ETi 400 High-Efficiency Pool and Spa Heater (part #461113).

What is a Pool and Spa Heater?

For those of you who don’t know what a heater is and how it operates I will do my best to explain it in a way that makes sense for hopefully everyone. The heater is responsible for warming your water so you can enjoy your pool and or spa in the off-season and the evenings. There are three types of heaters available for your pool and or spa: natural gas, propane, and electric. Each functions a bit differently and is suited for a wide range of pool owners. When talking about gas heaters, are commonly known as a popular choice for pool and or spa owners because of how quickly they can heat the water. The waiting time to enjoy the warmer water is virtually nonexistent because of the high output they can provide (when referring to the spa as a pool will require a little bit of wait time). These heaters also are available in either natural gas or propane. Propane on the other hand will need a separate propane tank whereas natural gas needs only a connection line for fuel. These products do not rely on outside weather sources to heat your water making them a real viable option for most pool owners. There is also another option when it comes to these products known as an electric heater which does use the temperature from the outside air to warm the water. The warmer air is drawn into the heater and then transferred through a heat exchanger to warm the swimming water. These heaters are ideal for spa owners in a warmer climate that’s above 40 degrees Fahrenheit because they do run depending on outside weather sources.

Pentair ETi 400 High-Efficiency Pool and Spa Heater!

The ETi 400 efficiently heats your pool with a blazing-fast performance to reach your target temperature in a snap. Equipped with the industry-exclusive TitanTough Direct-Fire Titanium Heat Exchanger, the toughest heat exchanger ever built, the ETi 400 can deliver years of reliable heating. And with 96% thermal efficiency, more of every dollar you spend goes directly into heating your pool. Paired with simplified installation and an ultra-quiet noise level, the ETi 400 can make your backyard oasis warmer and cozier for years to come. Titanium is known for excellent corrosion resistance, high strength, and lightweight. The job of the heat exchanger is to capture the heat from burning gas and transfer it to your pool’s water—the more efficiently, the better. But, the combination of operating heat and pool water chemistry can be tough on exchangers, leading to corrosion and failure. That’s why Pentair made the ETi 400 High-Efficiency Heater’s direct-fire heat exchanger from titanium. It provides long life under extreme conditions.

Key features and benefits:

• Corrosion-resistant TitanTough Direct-Fire Titanium Heat Exchanger is the strongest heat exchanger ever built for years of high-quality, trustworthy warmth.
• 96% thermal efficiency, the highest efficiency ever built in its class. For every $1 of natural gas that’s piped into the heater, 96 cents go directly to heating your pool, so you get more bang for your buck.
• Flexible installation features, including orientation options for gas line connection.
• Quick access to the keypad controller for user convenience.
• Large Removable panels make accessing the heater internals quick and easy.
• 3-year parts and labor warranty provided by Pentair
• ETi 400 is 400,000 BTUs (BTU is the quantity of heat needed to raise one pound of water by one degree Fahrenheit). The higher the BTUs, the higher the heating power and the faster your pool can heat up.

These heaters are built in a way that can stand up to the toughest conditions 1,800° F flame temperatures and pool water chemistry are all in a day’s work for titanium. Design elements that boost durability and efficiency. No welds, crimps, or joints that reduce corrosion resistance. Tubing is shaped for maximum flow and efficiency. Industrial chemical processors lean on titanium. When handling concentrated chlorine compounds, industrial processors rely on the corrosion resistance of titanium piping and heat exchangers. They do also make a conversion kit for these heaters designed specifically to convert natural gas to propane but we will go over that topic on another blog/day.

Overall the quality and production of this heater are simply unmatched. If you are looking for the best heater on the market at an affordable price then look no further.
