Garage heater - low temps
I have an insulated garage that I want to heat, but just above
freezing. All the heaters I have will keep the temperature at 14C (57F) or higher, which I don't want. I just want it slightly above 0C (32F) to avoid the objects in the garage from freezing. Does anyone know of such a heater? I can't seem to find one. Thanks! |

I've never seen lower but that does not mean they don't exist. |

Put a refrigerator in the garage and leave it open. The interior temperature of a fridge should be around 40 degrees, so an open fridge should keep the garage at 40 degrees year round. QED :-) |

Garage heater - low temps
It's a little expensive ($48) but McMaster-Carr has one that you can plug any heater up to 1500 watts into. Go to
www.mcmaster.com and search for part number 1940K8. A bigger issue might be the capability of the heater to maintain the temperature. Unless the garage is *really* well-insulated, and free of significant air leaks (most garage doors leak like a sieve), the heater may have a hard time keeping up when the weather gets really cold. Depending of course on how cold it gets in your area! Eric Law "Mark" wrote in message oups.com... I have an insulated garage that I want to heat, but just above freezing.

These are normally supplied from 240 V, so you can get several kW of heat from ordinary 14 ga wiring. Most makes of baseboard heaters seem to have auxiliary thermostats that you can install inside the wiring box at one end of the baseboard unit, with the temperature-setting knob sticking out through some kind of knockout. If you look closely, you'll probably find that there are two different models of this thermostat offered. One model has an "off" position, allowing you to turn off the heater entirely. The other model does not have an "off" position, and it's deliberately calibrated so that if you set it to the minimum temperature, it will come on about 4 degrees C (about 39 degrees F). That's what you want. Dave |

I've been looking for a 40F degree thermostat for 10 years now, let me know if you find one. I have a boiler that heats the garage slab and the basement slab, and like you I want to keep the garage just above freezing, currently I have to keep it 55F. |

The other poster's suggestion of taking a good look at a few makes of line-voltage thermostats for electric heat is a good one. Over thirty years ago, we found that some thermostats start at around 50F with an offswitch, and others don't have an offswitch, and start around 36F. We wanted the 36F ones to keep a cottage just above freezing. -- Chris Lewis, Age and Treachery will Triumph over Youth and Skill It's not just anyone who gets a Starship Cruiser class named after them. |

You know..."I'm going to Florida for 3 months. What's the lowest I can set my thermostat to?" I don't recall that the answers started with a "3". I'm sure it was much higher - and it wasn't related to the minimum allowed by the thermostat. It was related to actual environmental factors. Can anybody concur with what I think I remember? |

Would depend on the structure and ambient conditions of the location more than just the temperature as to what would/wouldn't be a problem. Here (SW KS) there's no problem from a condensation standpoint in a totally unheated shop area. In a humid area, not so much. Don't believe there's a single right answer (in fact I'm sure there's not) for all situations, but can see something like 50F being ok as a generic answer that would cover most situations that a generic column of the sort would respond with. That's not the same thing as what any individual shop could use a safe minimum by any stretch. -- -- |

In reading some of the questions that get sent to the Home Repair section of our local newspaper, I think I recall something about issues with condensation if the temperature is kept below some magic number (50?). This sort of thing is going to be very dependent on conditions. Not just environmental, but building structure and ventilation. As a simple example: our garage. It's vapor-barriered (6 mil plastic) and insulated with decent attic ventilation. When we moved in, the floor was just gravel. Unheated. Approximately two days per year (usually in the fall), there was a moisture problem that caused bare metal (eg: my tools) to begin to rust. Visible condensation everywhere. A few years later, we had a concrete floor put in with a layer of foam board under it. Moisture/rust problems _completely_ disappeared. There are now heaters in it, and I only turn them on when I'm going to be working in the garage for extended periods during the winter. When the heaters are off, the temperature in the garage can drop as low as -30C or lower during the winter. Zero moisture problems (except when the ceiling vapor barrier fatigued in a few places and fell through, and the attic got too warm - icicles and condensation at the ruptures.) The cottage is similarly well insulated and vapor barriered (kraft insulation). We heated the cottage itself to 4-5C. At first there was a moisture issue _under_ the cottage - concrete block foundation, dirt floor, and we also kept the pump area warmer by enclosing the section with a double "curtain" of 6 mil plastic and a fan heater modified to operate at around 5C. But that was eliminated by power venting the crawl space outside of the "bagged" zone. The only moisture deterioration problems were in the cottage ceiling due to "cathedral ceiling" (2x6 Cedar T&G, 1" foam, sheathing then shingle - no ventilation), no sunlight due to trees (roof stayed damp) and (eventually) carpenter ants. Everything was torn off but the T&G, "joists" were laid over the T&G, bat insulation with a 2" airgap under the sheathing. Moisture problems eliminated. Anyone saying "don't go lower than 50F" or something like that will be doing a CYA because they don't know whether it really will cause a problem or not. Whether it causes a problem is determined by the building and weather conditions. -- Chris Lewis, Age and Treachery will Triumph over Youth and Skill It's not just anyone who gets a Starship Cruiser class named after them. |

If you have some way to calibrate it, it may be possible to tilt one of the mercury switch thermostats enough to lower its operating point adequately. It may be possible to alter the internal spring mount to accomplish the same thing. Some RV thermostats have no OFF position but I so not know what the minimum setting is. Don Young |

There is something called a "frost cube" ? thermostat that you can control any heater with. I'll see if I cand find the information. |

I have a ceiling mounted electric heater with fan. Not sure of the exact thermostat range as it's unmarked except for little dots and an off position. I keep at "just on" over the winter and it keeps my insulated shop at about 40 degrees. When I want to spend time out there working, I just pop in, turn it up a bit and within 15 minutes or less I can work in my shirtsleeves. At a rate of ~ $0.1035 per kWh the affect on my monthly electric bill is negligible. If you can't find one looking through Grainger, et al, let me know and I'll pull the model number and make for you. Alternatively, I suspect that it might not be all that difficult to find a line voltage thermostat that would operate in the range you want/need. Just wire it into the circuit and leave the thermostat on the heater set to your preferred "working temperature". Crank up the external line voltage stat when you want to work out there, turn it back down when you just want to keep it from freezing. |

I agree with the poster that you would think there would be more quality choices available for that kind of thing, but I couldn't find any other choices either when I was looking. I've used those Thermocubes for livestock tank heaters, to prevent them from staying on when the air temperature rises above freezing. They are not very reliable. I wont buy them again. They do sell thermostatically controlled fan switches, made for large barn fans, which are intended to turn on the fan when the barn temp rises above a set temp, such as 70deg. They are 120V switches. But I dont think they go down to freezing temps. I believe they make similar things for heating controls. Check out www.grainger.com They sell a lot of that type of thing. The OP could make a control if they are handy. Mount a relay in a suitable electrical box. The relay contacts must be at least 15A. (20A is better). Put a plug on cord and an outlet on this box. The plug goes to a wall outlet, the outlet feeds the heater. Then mount a 24V transformer on the box, and run wires to a plain thermostat (not programmable). The relay must have a 24V trigger coil, the wires from the thermostat feed that relay trigger coil. It's hard to explain without a wiring diagram, but it's a simple circuit. A thermostat is really just a switch that is controlled by temperature. It's just switching the relay to the ON position when the temperature falls below a certain temp, such as 40deg. The relay contacts are 120V and they turn the heater on and off. I built something similar once, but in my case the relay turned my furnace on and off, based on a sensor on a woodburner. When the woodburner got above a certain temp, the furnace was turned off. The reason for this was because both shared the same ductwork. If both the furnace and woodburner fans ran at the same time, the big blower in the furnace would overpower the small fan on the woodburner, and cause it to self destruct. This relay insured that both blowers did not run at the same time. Relays are very useful for lots of things. |

Has double attached garage insulated like main building. Small potable heater rated at 1500W max. keeps things from freezing. |

Us folks closer to The Equator have a problem when Canada sticks it icy cold tongue out at us in wintertime. ^_^ [8~{} Uncle Freezing Monster |

Garage heater - low temps
I have an insulated garage that I want to heat, but just above freezing. All the heaters I have will keep the temperature at 14C (57F) or higher, which I don't want. I just want it slightly above 0C (32F) to avoid the objects in the garage from freezing. Does anyone know of such a heater? I can't seem to find one.

The description at the on-line Honeywell store says: "It's important to note that this unit will not work with line voltage systems, multi stage systems or heat pumps with or without auxiliary heat." However, I would think that any number of low-voltage-line voltage relay would work, no? http://www.grainger.com/category/ecatalog/N-1z0dqxk |

On at 35F, off at 45F. If you want to work in the shop, unplug the heater from the thermocube and plug it in directly, letting the built-in thermostat do it's job. |

IF it was my problem, I would take the thermostat apart and adjust/bend something associated with the temperature sensor. Nothing to lose and maybe a lot to save/gain.

Thanks! my best friend put a engine heater on his vehicle, with a heavy duty timer turning the heater on at 4am so his vehicle would be always ready to go at 6am for work. perhaps the OP wanted his vehicle above freezing? |
