HE250 TrueEASE 17 Gallon Advanced Bypass Evaporative Humidifier

Product had a faulty part from the factory but they issued me a replacement part immediately and it works great now.

Used this humidifier to replace a fan powered humidifier on a return duct. The old humidifier could hardly raise the RH at all due to there being no room to install it on the supply side. The automatic damper on this is worth the additional cost as it improves efficiency of the system greatly when the humidifier is not in use.

I chose the largest unit, because the air flow through it is low in my system. I installed a Double Hybrid geothermal heat pump (by Energy Catalyst Technology of Albany NY), which circulates both water (to baseboards) and air (via ducts). The air flow is fairly low and I knew I wouldn't get anywhere near the advertised 17 gallons per day of water in the air. That's OK. The amount of energy needed to vaporize 17 gallons a day would be huge. I am happy with 3 or 4 gallons a day. Of course, I have no way to measure the water usage - I am just comparing the humidity level, which is running a bit higher than with the portable unit, which used 2 gallons a day.

On average, I install a half dozen of these things per year. I have found them to be the most reliable humidifier on the market. That is key with me. I've had zero call backs or warranty claims. After installation, they require nothing more than a $15 water panel and a quick clean-up with a shop vac once a year. No fancy steam canisters, or special water filters needed. Plus they only use a fraction of the electricity that the steam units require. The HE250 is the advanced model. It cycles the water on and off, just enough to keep the panel wet, but not waste a bunch of water. Be aware of this, before you claim the unit is faulty. It's designed to minimize a steady flow of water down the drain. The manual states it can be installed on supply or return ducting. I only install on return ducting. The laws of physics say water will evaporate faster when atmospheric air pressure is less. Tapping into a hot water pipe also seems to help.

Fast delivery and easy install. Working perfectly for a month.

Worked for a day, Honeywell support would not help beyond the person reading diagnostic steps from a computer. The solenoid would no longer pick, I told her the coil metered ok, 24v ok, humidistat would call for water but no pick. Board had to be bad. Support said no parts because I installed, not a contractor. Supplyhouse was awesome, sent it back and bought a Aprilaire. The Honeywell had a automatic damper that only opened when there was a call for humidity, pretty cool, The Aprilaire is not as advanced, has a manual damper, no control board, just a simple 24vac solenoid

i installed this myself in a few hours. instructions were easy to follow. it very quickly improved the comfort level in my home.

Great just what I was looking for
