Another heat source would be a 20 or 40 watt reptile heater available from Amazon the will screw in the same as a light bulb. The danger with light bulbs are they are fragile and water Vapor condensing on them is also a danger.
Fair point although i have used this method along time and have not had any issues. Since regular bulbs are getting harder to find your idea may be where i end up going. Thanks for the tip and thanks for watching!
I have to heat a small well box (around 4 by 4) and a pump house (around 8 by 10). I use a decent oil filled heater and a cheap resistance fan heater in the pump house. The well box has one cheap fan heater. I set the fan heaters to 1200 watts output. This arrangement works well using commercial greenhouse thermostats to control the heaters. The cheap fan heaters have very unreliable internal thermostats so I set them to a higher setting than the greenhouse thermostats. This means the greenhouse thermostats control the heaters. It only takes a minute to set a heater and its external thermostat, along with testing them. The greenhouse thermostats work very reiliably, and you can accurately set the working temperature with them. One odd thing to watch -- most greenhouse thermostats have a switch to select "heating or cooling". For an application like this, it is critical to set the thermostat to "heating" or else you will have a real problem. I have the switches locked on "heating" so that I can't accidentally bump them to the wrong setting. The well box sits close enough to the house for a wireless indoor/outdoor thermometer to work, so I can easily monitor the temperature. All this his makes for a bit of overkill, but it works.
@@frankshomestead No, not impreseive. I had a freeze-up in the well box just after moving into this house. I wanted something very reliable, and installed these components. I trust the commercial greenhouse thermostats because the people that use them have part of their income riding on the reliability of these devices.
Can you add a thermostatically controlled switch so you don't have to do the plugging/unplugging routine? Also a computer case type fan would keep circulating the air for pennies as well?
Nice stuff man! Quick question... how far is your farthest faucet from your pressure tank? Putting my pressure tank about 120 ft from my farthest faucet, but not sure if pressure will hold?
I adjust them as the temp rises and falls. For example, right now we are experiencing a warm spell so I have unpluged all of the lights. I will start plugging them back in when the temp gets closer to freezing.
