I will be using this in a barn with two water bucket heaters that will be on 24/7 in the winter (70W each). How big of a system will I need?

70w x 2 at 110 volts? Amps = watts/volts. Amps needed 140/110 x 24 hours =30 amps in 24 hrs. A Renogy Starter kit of 3 panels puts out 300 watts, roughly 1500 watts, or 13.6 amps daily. So 9 panels? Ask Renogy. Also need batteries (golf cart batteries are great) and inverter.

It depends on where you live and how much sun you get. Based on 140W 24/7 the 300W "kit" won't be enough. That doesn't mean you couldn't do it with more panels. Just don't buy a "kit". That comes with a dedicated charger for the wattage the kit comes with. Check on line or with someone who can give you the calculations you will need for wattage and but individual panels and then size a charger for your needs. I had to do the same. The panels that come with the kit are top notch and can be bought by themselves.

There's multiple sizes selectable here. I prefer yo run two undersized heaters so if the thermostat goes bad i in one it won't cook the fish. For a 39 gallon I'd think you'd want like two 100w heaters.

If it's working there will be no ice in the center. After a heavy snow you may have to remove the build up in the center. It runs on only 100 watts so it won't get supper hot. You can get a much higher wattage heater at a farm supply store but they cost a lot more to run.

1500w - 2000w. If the heater is turmed on for longer time (hours or more) I would recommend 2000w.

Depends on how much temp change you need. If your ambient room temp is in the high 60's or low 70's and you're looking to get closer to 80*, a 50 or 75 watt will work in a 30g. If you need more temp increase than that, or just want a more efficient heater, I'd look at a 100W.

This is Generac's basic automatic standby system and also you it's output depends on what fuel type you'll be using (7kw - LP, 6kw - NG). It should be sufficient enough to run your furnace (provided it's oil or gas fired), your fridge, your well pump, a microwave, and some lighting/receptacle circuits. This is all we would typically load this unit. No split system A/C, electric range, dryer, wall ovens, electric heat or similar large demanding loads should be put on this unit. Most whole home applications require 14kw and up (depending on load calculations and Generac's recommendations).

I use it in a 24x28 garage. I do work in the garage in the winter and it will keep it at 70-75 degrees. I was usi9ng milk house heaters before and they kept burning out the thermostats . For me this heater works great. Lloyd Jones

I'm also in Ohio, and I doubt several of these could heat 800 sq. ft. decently even if your wiring could handle the load. It would take some calculating, but I suspect the electrical cost would match the propane unless you are willing to tolerate cold indoor temperatures.

I have in a room in the garage that is 8x20ft and no problem in getting this room to 70F, takes about 10 minutes and stays there until I shut it off. Have seen other comments about this heater for room sizes up to 200 sq ft.

It depends on the capacity of the thermostat. If you have 3 heaters of 1200 watts each, and your thermostat is rated for only 3000 watts, you are only able to run 2 together.

I own two of these heaters one purchased on 2010- it is now on its fifth winter and the newer one (2012) on its third winter, in use in my bedroom. I needed one left mostly on 400 watts (the top rod) and sometimes on 800 watts - aimed towards my outside wall in my laundry room to prevent frozen pipes. It is on 24/7 and I have had NO problems with either of them and simply store them in the box they came in when I warm up. HIGHLY recommended.

No.... not simply. The existing power wires to your heater is not enough. You will need to upgrade the power to 2-each 40 amp circuits. If you only have 2 people in your household you should have enough capacity with the 18kw model. It all depends how many hot water faucets are turned on at the same time. With this unit I would estimate 2. Also make sure to figure in the dish and clothes washer.

According to Eheim, the following heaters should be appropriate:Model 3616 150W heater: 53-79 gallons (US)Model 3617 200W heater: 79-106 gallons (US)If your tank is in a room that gets very cold in the winter, you might want to go with the 200W heater.

I've had the same basic question for some time now. It's surprisingly hard to find out how much water a specific machine uses, but you could try researching that first. (Personally I had no luck.) One estimate that's out there is that a typical front loader uses 15 gallons of water. I figure slightly more than half of that is for the (cold) rinse, meaning in a worst case scenario (cotton whites) you would need about 7 gallons of hot water. That said, most water heaters start delivering cooler (i.e., warm) water as they approach their capacity. In other words if you have a 10 gallon tank the temperature might start dropping off significantly after using only 8 or 9 gallons of water. So you (I) might be better off with 10 or even a 20 gallon tank. My problem with all these small "point of use" tank type heaters is that they are low power, which means easy electric hookup but really long recovery times in terms of gallons per hour. My advice for someone building from scratch and wanting point of use for a laundry room, even with a slop sink, would be a small tank-less heater. You could use a 30 amp unit like the Bosch AE7.2, have limitless hot water with zero recovery time and about the same up front cost, though you would have to run however many feet 10/2 wire (relatively cheap) and add a 30 amp 2-pole breaker, also cheap if you have the room in your electrical panel. I wish someone made a high-power (30 AMP 220V) small-tank (10-gal or less) heater, but so far I haven't been able to find anything like that. That would be the best of both worlds, since experience has shown that small tankless heaters can be finicky, delivering bursts of cold water, needing to be reset occasionally, and are extremely sensitive to changes in water pressure, which is a big factor if you live in certain areas or are on a well like me.

Very happy with the heater. Can set temp very low and the 10' by 16' room in the barn will stay just above freezing. Also if you turn it up it can run you out.

We run one of our kozy world heaters off our big 300 tank, but for our guest cottage we use a 20lb, about to increase to a 40lb just to keep from refilling. Runs fine for us.

A room about 10 ft long by 13 to 15 ft wide (130 -150 square feet) with average insulation. The 475 watt envi heater has been specifically designed to heat an average room measuring 130 - 150 square feet in floor area, to between 68 and 72 degrees, even in the coldest parts of the country. In rooms that have one or more of the following conditions: inferior insulation, many windows, staircases leading upwards, adjoining rooms that cannot be closed off (open plan) or outside entrances - this ratio may have to be lowered slightly. For rooms with above average insulation or warmer climates this ratio might be able to be increased. You can add as many heaters as you like to heat any size room, home or office. For rooms with no insulation or for rooms such as sunrooms with entire walls made of glass we recommend a ratio of one 475 watt heater per 60-80 square feet of floor area.
