Honeywell HM750A1000 Electrode Steam Humidifier

The Honeywell HM750A1000 Electrode Steam Humidifier is a specialized product designed to work with a ducted HVAC system. It heats water to create steam that is then distributed throughout the house via a heat-resistant hose inserted into the ducts. It is not suitable for use as a room humidifier or in any other manner. The unit can be easily integrated into an existing system if the appropriate wiring connections are in place. It can be connected to a thermostat and controlled based on humidity levels. Some users have added a Honeywell differential pressure switch to ensure that the humidifier only runs when the furnace blower is on. This helps optimize energy efficiency. The unit does not require heat from the system itself, as it boils water to generate steam. However, it does need to be connected to a water line. The control unit of the HM750A1000 is not weather or water proof, so it should not be installed outside. It is recommended to install it on the furnace exit air duct. The unit can operate on either 110V or 220V, depending on the jumper setting. While it delivers more steam with 220V, it is still efficient on 110V, and many users have reported satisfactory performance on this voltage. There is some uncertainty about using reverse osmosis (RO) water in the humidifier. While RO water has minimal minerals, which can extend the life of the canister, some minerals may be necessary for proper functioning. It is advised to contact Honeywell directly for clarification on this matter. Overall, the Honeywell HM750A1000 Electrode Steam Humidifier is well-received by users. It is praised for its easy installation, compatibility with existing wiring, and effective control of humidity levels. It is Considered an improvement over previous models, such as the Honeywell TrueSteam. However, some users have experienced issues with fault codes and sediment buildup, which can be frustrating.
