I use a oil type hooked to a johnson controls thermostat I had to bypass the oil heater controls and wire the thermostat directly to the coils because the heater had a digital settings panel and it wouldn't turn back on after the thermostat cut the power, if I get a new one I would get one without any digital parts to avoid the extra wiring hassle. I had a really hard time maintaining humidity during winter months. So after alot of wasted money on the small "room" type humidifier I got a while house one for that room, works great
