Shop Space Comfort

Published by Rob at 8:47 am under Shop Organization,Thoughts and Banter

Got Comfort?

Woodworking season comes around yearly, with Labor Day behind us, many of the summer outdoor oriented activities and chores are soon to be waning. The colder weather will be along soon enough to push us in and keep us indoors.

This is good, it spawns the need to be creative through other ways, and hobbies fill that gap. Problem is, many of us have to use a space for our woodworking hobby that is not exactly comfortable during a good bit of the indoor season. When we are cold, we don’t often enjoy what we want to enjoy as long or as much. We are more in the mode of just do it and get er’ done, rather than enjoying ourselves, where thinking through the process, being in the moment, and feeling like we relieved some stress are all big parts of having a good time. If it isn’t a good time, let’s face it, we generally avoid it.

To add, when you are cold, humans do not think as critically, and can even become distracted from slower thinking. Woodworking, like other tasks that require concentration, really does want your attention in many, many ways, because it is a very detailed endeavor, which can be inherently dangerous as well, so how you help yourself overcome these issues while trying to enjoy the woodworking season is a question that is a good thing to have on your mind.

It isn’t often I am going to endorse a product, in fact I am trying not to, but I am here to speak from the experience I have with the product I bought. This is not a review or a comparison either. I haven’t compared this product to any other. In fact, in this instance, I am using the product I bought more as a frame of reference, so those interested can use this as a frame of reference for their own needs. My want is to help you stay warm in the shop, period. It was my want too. I bought this as a ‘what the heck’ purchase, meaning I did my research, but I really had no idea if my purchase was the best choice or if it was going to work adequately for my purposes. I do not enjoy being cold, and after asking around, no one really knew what to tell me. I got lucky on both counts, because it did work out for me. In fact, it exceeded my expectations. Now that I have tried it, I’ll share my observations with you.

That is the Mr. Heater brand, Big Buddy Heater. In my shop, it is hooked via an accessory hose to a 5-gallon propane bottle. I just use the propane bottle off my BBQ as my fuel source, because both items seem to get the most use during opposite seasons, and as such it just makes sense to use the bottle I already have. I also bought the wall wart DC adapter that powers the small fan in the unit. The unit is user configurable for portability, it can also utilize 2 disposable type propane bottles housed in each side, and the fan can be powered by “D” cell batteries. I did run it off Duracell’s for a while, and the battery life is quite long.

It is a ceramic element heater with built in piezo electric starter. It has it’s own starter with thermocouple, three heat settings that give you 4000, 9000, or 18,000 BTU per hour. It is CSA certified for indoor and outdoor use. It has oxygen and tip over safety switches; you can even mount the bugger to the wall. It would also be a great thing to have during an extended power outage.

My shop space is a 2-car garage. It measures 20×20 so call it 400 square feet, I have 9-foot ceilings so cubed I have 2700 cubic feet. I have insulated walls covered with drywall, and an un-insulated metal garage door. My observations last winter were that the 18,000 BTU setting could raise the temperature in my space 8-10 degrees F per hour on average. Outside was around freezing, my garage is generally 15-20 degrees warmer that outside is in the winter due to the hot water heater and a few other appliances that help warm the space a bit. Once I was between 60-70 degrees, turning down to the 4000 BTU setting would often maintain the temperature or perhaps very slowly gain a degree or so an hour based on the outside temp and the time of the day.

The unit does have a fan, and I do advocate using it. Mr. Heater refers to it as a blower fan. It is not a strong fan; so do not think forced air, because if you do it will disappoint you. The fan is helpful though. The fan does help draw the cold air near the floor, into the heater rather than have it heat the air it can get by it just being a radiant heater. This increases efficiency. I also use a fan in my shop to help circulate the air, and this really was a big help in keeping the entire space in good, comfortable shape. I would definitely use a fan with this heater in the same room, and oh, the fan does not need to be near the heater, all you are trying to do is keep the hot air from stratifying near the ceiling.

Mr Heater claims that depending on the settings you use, and it is going to vary, that the 5-gallon or 20 lb bottle will get you 25-110 hours of use. Not bad really, when you consider the amount of shop time most woodworkers average per setting generally speaking. It is also not bad when you consider that the Big Buddy is making heat from propane pretty efficiently with the fuel it is given, so if heating your space is of value to you, improving your spaces’ ability to retain heat should be as well.

For your own research, I’ll include Mr. Heaters online product sheet of the big Buddy Heater here: Big Buddy Indoor Safe Heater and let you know that the heater, short hose and electrical converter for the fan will run you in the ballpark of $160, though you may find alternative pricing, taxes and shipping from nearly anywhere.

Your space may be just like mine, or it may be smaller, larger, with more or less insulation, and your weather may be far more severe. This may be all you need, or you may need two, or less or something bigger. The main things I want you to take from this is that this heater works well, given the range of heating capability it has, coupled with the space and conditions I describe.

You are welcome to think about your own space and how you may need to augment the non-scientific observations I gave for performance to best gauge your own best guess at estimated outcomes. You are welcome to use my comments section or my contact page to ask any questions that you may want help answering, I will give them my best, based on my own observations. Please feel free to comunicate any time. I felt the product is a good fit for a 2 car garage sized space, a good value for the money spent, and I would buy it again.

So if you are thinking you want to enjoy a warmer woodworking season, a heater with 4000-18,000 BTU capabilities may be just what you are looking for.

Happy Woodworking!

    I bought one of the cheaper radiant heaters that mounts directly on the propane tank, and have regretted it every since.

    This is just what I need! It will work well in my shop.
    Thanks,

    I typically work in my basement but I will be setting up some work this winter in my 2 car garage. Like you my garage is unheated and I’ve been wondering how I could keep it a comfortable temperature during “working hours”. This article was very helpful. Thanks

    I think the most important thing you is *insulate*. Walls. Ceilings. Insulate.

    I too had one of those 1 topper propane heaters in my uninsulated bay of a three car garage. I have the burn marks on my forearms to show it… :)

    A few years ago, I wall off the bay and insulated everything. I can now keep the “sharage” at 70* with a $39 oil filled radiator heater and a simple box fan. When the temps dip to 7* outside.

    Like Rob said – you need the fan to circulate the warm air. But, in my opinion, the most significant contributing factor was the insulation!

    Hey, Rob. Greetings from the upper left corner. I thought you moved down south to get away from the cold and damp.

    I have the little brother of your heater, and use it as a “spot” heater in the bathroom during power outages (frequent here, as you know). Haven’t tried it in the shop, that’s a good idea. I also have one of the other kind that screws on top and it flares up sometimes, though I usually keep my forearms out of the way. Sure can cause a moment of excitement when it lights off the varnish fumes.

    The bad weather here doesn’t keep me indoors much, in fact I just finished cutting up the blowdown from the big windstorm that caused our last power outage. Firewood warms you twice… (but I still use a lot of those pocket handwarmers).

    Hi Parker,

    I did move here to escape, er, get away from that cold wetness, and for the most part, My heating costs are a lot lower. (lets not go into the cooling costs eh?) But I do prefer this climate over the one you have. I spent many a year there working outside in it. I’ve had my fill. Still, I have used the heck out of this Big Buddy heater for three years. It warms my shop daily as I work in there daily, all winter. On High setting, (18,000 BTU) I find it will make a 10 degree difference in my 2 car garage with an uninsulated metal door in one hour, or slightly less.

    I have also used it in the house in conjunction with carbon monoxide detectors and have had zero detection issues. It heats the house more slowly than my garage due to many more square feet to heat, (typically 2.5 hours for 10 degrees of change) but once warm it will maintain the temp in the house on low setting with occasional bump-ups to medium. That is 4000 BTU on Low, 9000 BTU on Medium I’d buy it again, but heck, I have two of them.

    I agree, if your going to finish, particularly with really flammable finishes, heat up the shop and shut this off then finish. Fwiw, adequate ventilation is pretty important when finishing anyway. Just sayin.

    Pocket warmers are never a bad thing. I used to buy them by the box full!

    Bests,

    Rob
