I just replaced the 50 year old Hydronic Unit Heater in our garage. The fan motor had finally given out and parts were not available. It had a 2 speed fan and I usually ran it on the slower speed to cut down the fan noise. We have a bedroom on the other side of the back garage wall.I bought a Modine model HC33 unit heater with a 1/25th HP single speed fan motor rated at 1550 rpm. The fan is pretty noisy so I needed to add a Solid State Speed Control to slow it down. 1/25th HP at 120 vac draws about 0.3 amps. I ordered the KB Electronics 8811006 Solid State Variable Speed AC Electric Motor Control, 2.5 Max amp, 115V, KBWC-13K from Amazon. The on/off switch was a bonus!I am also using a Honeywell Aquastat to turn the fan on when the water is hot and off when cold. That should add some longevity to the motor.It works great! I turned down the speed until the heater is quiet and it still keeps our garage warm!

Easy to install, works good, but would have preferred for lower rpm on low.

This speed control installs as if it were a simple switch in the hot wire line, plus a ground. That makes it easy to install ... make certain the breaker is off and no AC is present. Cut or unfasten the hot line to the original switch (probably a pull chain ... I did this in the fan switch box) and run a two conductor plus ground cable to where you want the speed control. Install a heat resistant box (the control does get warm, not hot) Connect the two insulated cable wires to the two wires on the motor control and connect the bare ground. Splice the other ends into the original switch hot wire that you cut. Do this in a junction box. I was able to squeeze these "fan side" connections (including ground) into the existing box that holds the pull chain switch. I set the pull chain switch for "high" (it has high, low, off settings) and then I removed the chain since the speed control would now control on/off/and speed functions. To be as "correct" as possible ... Since the new cable going to the speed control now technically carries "Hot" to the control and then back to the fan motor, use a black magic marker to color the ends of the white wire black. That gives fair warning to others that both lines in the cable are hot.I mounted the speed control in a hallway from the garage into the house, just below the fan. I noticed that the speed control housing itself is a heat sink that sits out about a half inch from the wall, so I mounted the switch above shoulder high so that we would be less likely to bump into it.After setting the "lowest speed" adjustment so that the shutters would not flop closed, all works perfectly. My fan is a direct drive motor that pulls 5 amps and this particular speed control is rated for 8 amps. The control gets slightly warm to the touch when it has been running on low for a long time, but the heat sink dissipates the heat very well. If your fan has shutters, make certain to keep the low speed high enough so that the shutters don't start to close. If they do, it is progressive. The shutters close a bit; the fan pulls harder and slows a bit, and then the shutters close more. Eventually the shutters are almost completely closed and flopping. In that case the fan motor is working hard and getting no air movement so it could overheat .... NOT a good thing!
