What does the 2500- 5000 watt mean? Which is it? And is this unit noisy when blowing? thank you...

The thermostat on this unit will turn the unit on and off at different temperatures (I found low is about 0C - Freezing). But it is either on or off, full heat or none. The 2500-5000 W is that it is field adjustable to different wattages by taking the bottom of the unit off and changing some jumper wires to different terminals. So you don't have to worry about buying a heater that has too much watts. My wife works in a 600ft area with this ceiling mounted and says it's not too noisy at all.

It means that the unit can be configured to draw 2500W, 3kW, 4kW or 5kW, corresponding to 15A, 20A, 25A or 30A breakers. How much power it will draw is configured via jumper wires. Moving the jumper wires essentially disconnects parts of the heating element, so it draws less power overall. The jumper configurations are printed right on the access panel. They're also in the manual on the marleymep website. I'll also paste them here:BTU/HR, VOLTS, WATTS, BREAKER SIZE, AMP DRAW, JUMPERS17065 240 5000 30 20.9 NONE14215 240 4165 25 17.4 BLUE11365 240 3332 20 13.9 BLUE & YELLOW8533 240 2500 15 10.4 BLUE, YELLOW & REDIt's not noisy at all.

You can adjust from low (2500) to high (5000). I do not think the unit is noisy at all. I run it in my business and hardly notice it's on.

It is equal to having a box fan on high in my opinion. Not loud but you know it it on.

The wattage is the amount of heat produced by the unit. So 2500 watts is low heat and 5000 watts is twice the heat produced at 2500 watts and it would be high heat. The higher the wattage, the more area you can heat. When the blower comes on you can hear it but it is not loud.

Wattage is the amount of electricity the heater uses. Your electric company bills you in kilowatts therefore 5 kilowatts. 5000 watts is equal to about 17000 btu,s. 2500 watts would be half as much. I don't think the unit is noisy but then I am hard of hearing. Keeps me warm in two car garage.

Not sure... But I have 2 of them plus a 3000 watt amp all running off of a normal 15 amp outlet with know problems and I like it loud!

The unit is loud with the fan and burner going. Also you have a confined space, where the outlet is pointed is of concern. Again confined space, air quality will be an issue, possibly lethal.

This fan is absolutely quiet when running. In fact, I have had to go up on the roof to make sure that it is running after the last hail storm (it was OK). Very high quality unit. I don't know about Sone ratings, but I suggest the 30 watt over the smaller one. Hope this helps!

I just installed the 1575 in my RV, hooked to two 6v golf cart batteries. My observations; Does not show output wattage at all times, is very LOUD when the fan/s come on. They run for about 5 - 7 minutes and is almost unbearable.I returned this item due to the noise when the fans came on. It did run my Refrig without a problem using my batteries.Again, the only problem I had with this item was the Noise.

Watts are how much power it uses. BTUs are how much heat it puts out. Not the same thing. I'd also like to know but assume it's not great since it's not mentioned. Quality similar models, at only slightly higher cost, can put out 5200 BTUs.

I don't know but I do know that it these units are extremely noisy and I returned it.

It is similar to a large box fan on the high setting, which is fairly noisy. Be aware that this unit will suck a lot of air into the room you are trying to cool. If the air coming in is not already fairly cool, this unit won't do much to cool your room. It's kind of like trying to cool a room while leaving another window in the room open. Sealing the room up tight will cause the unit to overheat and cycle on and off. See Hoofhoof's (or my) review.

I don't know how much power it uses but it was so noisy that I returned it. Good luck.

Honestly I have no idea about the efficiency of this unit. However I must say that this is the loudest little power inverter I have ever owned. I don't use it because it has a cooling fan that runs all the time and is quite loud.

Joan,I measured the first of the two heaters I bought using a Kill-A-Watt meter. It said 7.5 Amps on Low and 12.5 Amps on high, so that would be 900 Watts and 1500 Watts on high. The fan always is on "high", which to me is a benefit because the volume of air is the same, just warmer or cooler. Or unheated, if you use the fan-only setting.Martt

Mr. Heater seems to keep improving these units. I just bought mine in September of this year, and it was manufactured in May of this year (2013). I bought it at a local big box store.The fan on this unit seems pretty quiet. Certainly not noisy as others have reported in the past. You will hear the fan, but is smooth sounding an not obtrusive. My guess is that they've improved the fan quality in these current units.

Most 7500 watt models make some noise. The Champion 7500w is rated at 74db which is on the low end, but don't put it under your bedroom window. I bought a 40ft power cord to connect to the outdoor transfer switch input to keep it some distance from the house. There is a low oil shutoff and a gas gage.

It is a fan forced unit. It will blow out about 8 to 10 feet. This heater is quit a work horse. On high it really heats quick. On low it will maintain. Not sure what the power consumption is yet, as we have only had this heater about one month. Hope this helps.

It sounds like you are building something heavy-duty. The largest one I have built used a 750 watt. I found the engineering first class and the performance solid. I would buy it again. Built like a gamer, it's still running well after two years. On a smaller machine, the tickler starting circuit failed and they sent me a new PSU, postage paid. Your UPS needs to produce a full sine wave for it, is all. That's what Thermaltake told me, anyway. Good Luck.

All I can say is how I use it. I use it daily for 4 hrs constantly on a unit that demands 2500 watts. I don't have any issues to date. I hope this helps you.

Rather than a blower per se, it has a circulation fan. It can be heard from across the room but not overly noisy. Also a filter for that on the back of the unti can be washed time to time. On my second winter season with this unit and it is going strong and warms my loft nicely. Much prefer this over the forced air furnace.
