This small heater was perfect for my small 6'x8' plastic covered greenhouse and kept the temperature a toasty 50° when it was 19° outside

Ordered this for my coworker to put under her desk. She is always cold and I got it for her as a Bday gift. She loves it!

I ordered two of these for the winter. One for my garage and one for my nook by the back door. I have a lot of plants to bring indoors during the winter and needed the garage warm as well as near my back door (due to a doggie door it gets colder in that part of the house). These heaters are AMAZING!!! HIGHLY recommend! Adjustable temp setting and you can set it to warm or just fan. It shuts off when the desired temp is reached and I have had zero issues. It warms my entire 2 car garage with ease. There were mornings the garage was warmer than inside my house and I only had it turned about halfway up! 5/5

I bought this for my little greenhouse. It has been doing just fine until now. I bought it almost 4 months ago. It has been used when the nights got down into the 20's and 30's. The temp is going down tonight and it all of sudden no longer works. Disappointed and now worried about my plants.

Thank you for fine product! It really came in handy because last night we experienced a hard freeze and the heater saved the plants in the greenhouse!

Used in a fairly small, plastic covered greenhouse, about 6'x6' and 7' tall, and another heater in a another greenhouse about 8'x8'x7'. This heater is much smaller than the 10-years old heaters that they replace. Heats up quickly and the fan flow is strong enough to fill the area of each greenhouse. No issues with the heater keeping the greenhouses at 50 degrees, even when the temperature drops to 12-15 degrees. (The floors of the greenhouses are insulated, as well as the first 2' of the walls, so that admittedly helps.)

I needed a heater for my little green house. It’s an 8 x 12 with 10ft peak.Until this past week it was just handling lows at night, usually in the 40s. The past 5 days we’ve had some freezing temps and some as low as 26. So far this little heater has had no trouble in maintaining 55-75 range I have set on my programmable power controller. In years past I have used the milk shed style heaters. This little heater is just as good and is more efficient. The plants are not just surviving they are growing!

2024-09-05. Greenhouse heater by TRUSTECH. Thermostat. Space heater. 3 Modes. Fast heat. PTC. Overheat protection. 90° tilt. 1500W. Portable. Black/Orange.This heater by TRUSTECH is you old school heater with more efficient heating technology. TRUSTECH uses just one acronym which is PTC.PTC stands for Positive Temperature Coefficient. It's a technology used to generate heat. PTC heaters use conductors made of variable resistor materials. When electricity passes through these conductors, they create resistance, become hot, and generate heat in the surrounding area. The more electricity that is passed through them, the hotter they get. This is the same technology being employed in many Battery Electric Vehicles (BEV's) today. PTC heaters are very efficient at generating heat as they consume very little energy when compared to traditional heaters. Another great thing about PTC heaters is the "ptc effect". Because PTC heaters generate heat in the surrounding area, they never reach temperatures high enough to cause combustion or fires making them not only efficient, but very safe as well.I also want to point out the that this little unit is a power hog. Wait, whut? Didn't you just say it's energy efficient? Well yes, but it's not the heating that's consuming the power, it's the blower motor or fan. This unit advertises 1500W. Wattage is a unit of power in terms of energy consumption, not potency of efficacy. Volts × Amps = Watts. There are three fan settings on this unit, and between power the PTC heater and the fan, it can consume 750W (low fan) or 1500W (high fan). The fan is rated for 120V which is the voltage of wall receptacles in North America. Doing the math 1500W ÷ 120V = 12.5A. Most wall receptacles are rated at 15A, so if you're using this, make sure you don't have some other power hungry device plugged into the same wall receptacle otherwise you're trip the circuit breaker.Aside from the three fan settings, there is also a gradient heat dial. The dial doesn't really indicate temperature, and I wish that they did, but the amount of heat is continuously variable, so you can tweak it in small increments.The power cord is NOT grounded and only measures 6 ½ feet in length. This is quite short in my opinion, especially if you do plan on using it in a greenhouse. The cord is also loose, and they could have built a cord wrap into the unit for tidy storage. Speaking of storage, the unit also doesn't come with any type of storage case or storage bag.Functionally, the unit is very effective at what it does. It does heat up quickly and I love the 90° tilt. The "analog" dials make this unit "old school", and many may prefer it as there's no worry about faulty software or burnt out displays. The short cord and the lack of temperature reference is the biggest drawbacks of this unit, but it takes nothing away from it's simplicity and functionality.
