Please give the technical data: the combined resistance of the two heater elements, how many watts of electricity does it draw, BTU of heat it produce

just off my head, the current draw is about 1 amp with a 3.7v lithium battery. You can calculate watt and resistance from there. It's too hot to keep it on all the time. The heating element is rate for 3 Watt max. Using 2 NiMH AA batteries, you can leave it on all the time. It doesn't warm up a cool feet, but does keep feet from getting cold. Don't use Alkaline batteries. Don't know about BTU.

120 Volts, 60 Hz; continueous draw = 12.5 amps, minimun draw = 5 amps, BTU = 2,050-5,200; power use = variable from under 50% to 1,50eatts @ 100%.

The heating element uses 1500 watts or 1.5 kw per hour. Multiply the number of hours you plan to use your heater times 1.5 kw to get the kw hours. For example: 1.5 kw x 10 hours =15 kwh. Multiply the kwh x rate/kwh to get the cost. Let's use 12 cents/kwh. The cost would be 15kwh x $0.12 = $1.80 per day. 30 days would be $54.00.CFinch

Depends on the amp rating of your outlet. You will need to be able to draw more than 4000 watts from the outlet to have 4000 watts available from the heater.

BTU's and watts are both measures of energy. A BTU is approximately equal to 0.29 watts, so a 1000 watt heater that is 100% efficient would equal 290 BTU's.

I'm pretty sure it's a 750 watt heater and since it's a resistive load the AC power factor is 1. That translates to a little less than 7 amps at 120 Volts (US).

The installation instructions require a 60 amp circuit beaker. I had mine connected to a 60 then I moved and now have it hooked up to a 50 amp. I had my brother test the amp usage of my unit and it uses between 42 - 44 amps at full draw. It has two heating elements and uses only one at 21 -22 amp draw unless you use enough water to kick in the second unit. Then it draws the full 42 - 44 amps. The heater only uses one heating element for a shower, but if you run the showing and a sink, then it uses both heating elements to meet the demand. They require 60, but mine runs on 50 just fine. I hope that helps with your decision.

I don't remember the btu's but don't waste your money on it. It worked for the first 15 minutes and hasn't worked worth a crap since. It came with all the fittings loose underneath it and the valve to switch from propane to gas is broken. Got to buy something else now

This one uses 120 VAC and draws 8 amps. Watts = Volts x Amps so 120 volts x 8 Amps = 960 Watts. I didn't like this unit, it's very loud and you are limited by the cord. I like the one that runs on propane MUCH better.

If this is the same model you are looking at: Manufacturer Model: CF1500UV-WTA Coverage: up to 1000 square feet Watts: 1500 per hour (1.5 kw per hour) Amperage: 12.5 BTU Output Rating: 5600 Power Requirements: 115 volt AC, 1500 watt Quartz Infrared Heating System: four quartz infrared heating elements (lasts a minimum of 20,000 hours) Diffusion Coil: stainless-steel, designed to increase the heating efficiency Heating Chamber: copper lined for optimal heat transfer

It doesn't say in the manual but using standard conversion table the heater produces 750 watts which at US standard 110 volts which converts to 6.25 amps and on high it produces 1500 watts so draws 13.64 amps. Hope this helps. Side note, we have been using this heater almost daily for the past four months and think it's the best of 5 or 6 heaters (different types/brands) we've tried over the past few years.

It (was) 1300 Watts. But I would not recomend the Item anymore . It worked fine for less than one year and the little Knop on the Handle (connection) broke. then the heating element broke also.( I was told by the Company to ship it back in the Original !! box) Repair is more $$ then what i paid for. I bought a similar one (less $$ ) at an Aldis Store. And it works fine. Also 1300 Watts. Hope that helps ? good luck

Per another site (https://answers.yahoo.com/question/index?qid=20081023082349AAiiA4y) there are 433,000 BTU in a 20lb (BBQ size) tank. At max, the Mr Heater is rated for 45,000BTU/hr. 433,000/45,000 = 9.62 hours of run time.At min, it is rated at 10,000BTU/hr. 433,000/10,000 = 43.3 hours of run time.

I wish I knew, I don't know. Check the BTUs but the one I bought works great. Nice and warm in the in between seasons. For everyday use the home version is fine. Possibly the grade of metal is better?

The amount of BTUs. One model puts out 333,000 BTUs and the other 400,000 BTUs, so one will heat up your spa or pool much quicker

I checked the back of mine and it doesn't list BTU's it just lists 1500 watts. But I can tell you that this has been the best heater I love it! I purchased it last year around this time. I use it to take the chill off In my master bedroom and can adjust it with no problem without getting out of bed. I'm very pleased and think you will be happy and it not u can always return it . I have had no issues or problems with this heater. Good luck !

About 1700 BTU. It must be hardwired to a 240volt supply. Hope this helps you. King used to make a portable 120volt heater. You might try their website King-electric.com for more info
