DC heater for HAM shack
« on: December 06, 2017, 08:30:16 AM »
Hi All

I have been musing in my mind about building an actual HAM shack

Something small, entirely off the grid.

Solar power for electricity.

Lighting is no problem
Radio power is no problem

Heating by DC with solar? Problem

Now I intend to have a small shack. Like maybe 6'x8'

Are there any small DC heaters that are on a thermostat out there?

Thank you
Kid

  Use a lot of insulation and paint the building black outside,wear many layers of clothes because the cost of solar electric heat is way beyond where you want to go.Better if you use a propane or butane gas powered heater ...of a wood stove because a 1500 watt heater takes a large system to power off of solar electric....even if you use 250 watt infrared light bulb to heat YOU (hard on the skin) the solar electrics will be way more than most will want to pay and nearly as large as what is sold as 'whole house' solar.

Yeah I was afraid of that.

Can you get a propane heater that has a thermostat?

It gets 50 below here in the winter. I got to keep my radios from freezing their knobs off.

Do these run off DC, battery or AC for the thermostat controls?

The one I used needed an alkaline "D" cell battery ,this one in the link must use a piezoelectric start as it says:

No electricity is required which is perfect for power outages or any in-house urgencies.

that thing sparked my interest.
In what is the "infrared element" different to the propane and kerosene heaters?

I think you just have higher lower control as I remember mine use a D cell battery to heat a starter and these used a piezoelectric click button...also ,the one I linked is a wall mount while I just linked it as a example and might be able to look up a full ON/OFF controlled thermostat ,probably battery operated one in a day or so as I just got released from surgery and need a few days to recover .

  The infrared light bulb is about the lowest cost and power needed for heat as it heats items,not air and 250 watts will warm a man or a dark metal plate
can be shined at till it also begins to radiate heat...it will develope heat enough to melt some plastics so I would only run it when I was in front of it and needed heat.

I have my shack in a travel trailer a Jayco Jay Feather X213, I use the propane furnace and solar charge the batteries that power the furnace and radios. Works very well and we camp in during the summer. I use about (4) 20 pound tanks winter season, I use the shack/trailer about every weekend. I'm located in the northeast been down to -20 with no problems. I also have a hook up to my 500 gallon LP tank as a backup. I'm not to worried about running or storing the radios below freezing. Some of the old timers with tube radios just powered up and kept it on receive for 20 min before transmitting to warm up the glass. 

Using an electric heater and solar can be done but the system will be huge, far easier to store propane that has an indefinite shelf life and is cheap.

Yes,I agree,they do heat a Hamshack well.
