It looks light this has a sylvania instant start ballast which has a starting temp of -20F. Here is a link with the cut sheet for this model. Hope this helps. http://www.lithonia.com/es8/pdfs/osram%20high%20eff%20qhe%20brochure.pdf

That should be fine with this unit. The amount of water makes no difference to the meter, and 180 F is not too hot. I don't see a temperature rating on the unit, but I put 160 F water through it regularly without any problems. I don't see the extra 20 F making a huge difference.

I have used 3 Tempa 20s to replace other standard water heaters in my apt. complex units. #1, I would not consider a 50 gal water heater as needing a supplement. #2 the Tempra 20 is all you need for a bathroom tub or shower. I am in Wisconsin which is too cold for a 20. and yet they seem to work fine (28s are recommended for this cold climate). You may decide later to forget the 50 gal water heater. Hope this helps. Yes, I would recommend you make this purchase. [If you live in a hard water area, be sure to install a whole house water filter (about $40) ahead of the Tempra or the salts will damage the Tempra flow mechn.] I have used 3 Tempa 20s to replace other standard water heaters in my apt. complex units. #1, I would not consider a 50 gal water heater as needing a supplement. #2 the Tempra 20 is all you need for a bathroom tub or shower.

Not very much, I ran on one 12 volt deep cycle for 24 hours but was only 65 degrees outside, I can give you a better answer in a week when home, great unit

It should not be an issue. I am not sure what the cold rating is. It gets down to -20f here and they work fine.

Not a good idea. Temp is 110-115f., too warm for starter. You may be able to hook up to a rheostat; I've never tried it. Bill Leahy

It's 36 degrees F. Depending on the temperature of the room, I doubt it will run that cool. The lowest I've run mine is 64 degrees F. Usually it is set to 70.

I somewhat agree with ChrisMP. This unit can heat a large area (20X20) but not much more than that. I agree that the unit will be on all the time. It does not produce a lot of heat (hot air). It is best used to supplement your house heating system, used at a lower temp. I was using the Enerzen as a primary heater for my finished basement. On cold days (20's or below), this unit could not heat the room above 62 degrees. That's a little to cold for me. Now, on very cold days, I use the Enerzen to supplement a Vornado ATH1 that I purchased. The basement gets quite toasty. I hope this helps. I somewhat agree with ChrisMP.

Temperature-to-required-wattage is pretty nonlinear. I find the 3 o'clock position to be a good starting point. Try starting at 3 o'clock position and adjust as necessary.

Mike, it is a bad idea to buy this regardless of temperature. IF you get one with adjustment screws you might be able to zero it at the common 25m. If it has no set screws then who knows. Save the money from buying this piece of junk and purchase a better made one.

Ralph, my records show that the lowest temp we've had here in Sandoval County, NM since I installed the MA-S01 is 8F on January 13 this year. I don't believe low temps should be a concern and I the unit will work in conjunction with their freeze alarm which is rated at -50F to +300F (probably it's melting point). My only concern would be the batteries. I haven't replaced mine since installing in early January but I know that low temps affect battery performance. I've been completely satisfied with my unit and have had no problems. I put mine in a corner of my shop and the only caution I would observe is to not put or hang objects in front of the unit. My shop gets a bit cluttered at times and I have a tendency to hang bar clamps from a shelf in front of the unit. Bad idea. I entered the shop one day and because it didn't beep immediately I forgot until the alarm triggered. This was because the unit was playing peekaboo from behind the clamps. Great unit for the price, but I wasn't that impressed with the volume of the siren. It would probably send an intruder running but likely wouldn't wake me.

Yes. Definitely. And if you're talking about brewing. You're going to be starting around 140-160F from your sparge. It should take about 30 mins to get up to 212F. This is as long as you have 220-240V/30amp power supply.

You will end up with about 80/85% of your starting volume be it 1 gal. 5 gal. Or 10. Just know the more gallons you start with the the longer it will take to get to temp my 1st try at 10 gal. On hot plate took 3 hrs to get to temp

Hi Melissa, I live in Ct The 20,000 heats my living room,dining room without any problems 74 degrees on the number 3 setting(it goes up to 9) I think you should go with a smaller unit like a 10,000 btu or smaller which would give you more than enough heat. It stands about 24-25 inches high with the legs on ,you also can wall mount it.Steve

This is the unit that I bought and it only has one zone. I keep it set at about 60 F and it works nicely. It is not intended for white wine or soft drinks as it will not chill below about 56 F.

No, I have a thermostat hooked in-line, so it doesn't run below 60 deg. I don't want to be cooling the space in the winter, I want the opposite, so the house stays warmer. This is an awesome unit and works really well.
