Heat

What is the best way to heat a smaller shop. I have switched to propane from kerosene.

Larry,

What size of shop are talking about? What is the building type/construction.
Where are you situated compared to utilities?
There are a lot of unknowns, but generally the most efficient way to heat a building is with natural gas, it is cheap and burns clean. There are a lot of appliances that can be used with natural gas, all the way from your smallest unit heater to your largest make up air units and then there are options like radiant tube heaters, furnaces, boilers for hot water heating with a variety of heat exchanger options.
There is also the option of electrical heat if the area is small, it is generally more expensive than natural gas.
Another option is wood, again there are wood boilers away from the building or wood furnaces or wood stoves in the building. Where I am located some insurance companies frown on having a wood burning appliance in a wood shop, something you would have to check out.
Propane can be used just like natural gas, it is generally more expensive than natural gas and you require a storage tank for it nearby. You can use a furnace or a unit heater, make up air unit, but the appliance has to be approved for propane as the burner orfaces are a different size.
All heat methods of course require the proper venting so you don't fill up your building with carbon monoxide.

There is no "best system" for all small shops. There is only the best system for your given situation.

Propane is a good step up from kerosene assuming that you are going from an unvented kerosene unit to a vented propane unit.

Instead of telling you what is the best system I would tell you what to avoid. That would be any unvented system and any heat source, vented or unvented, that uses indoor shop air for combustion. Wood dust is explosive and should never be exposed to open flame.

I think in floor radiant with a NG boiler is the most cost effective and comfortable way to heat a woodshop.

In floor sounds nice. We are drilling holes in the floor constantly. That would scare the hell out of me.

My slab is 6" thick, the pipe for the heat is stapled to the foam insulation under the slab. You just don't drill all the way through, and when you abandon pins in the floor, you cut them off instead of pounding them in.

I get squeamish drilling holes in the floor though, but most anchors don't have to go terribly deep to do their job. The only thing I'm concerned about is a pipe not being where it's supposed to be and being too close to the surface.

The heat is outstanding, it keeps everything warm. Material, equipment, feet. Recovering time from doors being opened is surprisingly quick. My little shop has almost 600k pounds of concrete in the floor, once the floor is up to temp, there isn't much fluctuation.

Plus there's no air being handled or heating equipment being affected by dust. I wouldn't heat a woodshop any other way unless heat wasn't needed often. I'm in Minnesota, it runs almost 5 months a year.

You can pretty easily see the tubing in the floor with an infrared gun. My heating guy located tubing for me.

Best heat source for my shop.

On a professional site like this one, a smaller shop could mean 10,000 square feet to some. You might want to narrow it down a little.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
