I am purchasing a 34 ft trailer with 3 slides, aprox. 350 sq ft. What size BTU heater would be best. This would be the secondary heat source in cold.

I run the Wave 8, comfy when Temps are in the teens in a 28 footer with a super slide.

I bought the 6000 BTU size for my 30' camper, which is a high quality and well insulated unit. When the weather temps dropped to the mid teens and lower it would not even begin to adequately heat the camper. I will be replacing it this winter, don't waste your money, they will not do the job if your in cold weather.

the largest one you can get. i bought the small one and it is not big enough. i have a 32 ft with one slide.

This is a big heater for such a small space. However, there are a lot of variables to consider. Is this enclosed porch addition well insulated or is it mostly glass walls. Is it in the shade with a N. exposure or in full S. exposure shade free sun. Assuming the worst with poor insulation, single pane glass and a northerly exposure this is the heater for you if you want to keep plants alive or sit in this porch in the evening in the winter. An over-sized heater will cycle frequently. You may not want to sit or even have furniture within 2 feet or so from this heater. It is more efficient to have a small heater running a high percentage of the time than having a behemoth turning on for five minutes every half hour. When in doubt it is probably best to error on the side of a little extra capacity. There are internet sites that will work the math for you if you know square footage of wall area by type, wood, window, etc. You can calculate your heat loss in thermal units given a certain outside temperature. In this way you can precisely calculate your BTU needs. This is a good little heater. I use it to assist heat pumps on cold evenings as they don't work well below a certain temperature. It makes a big difference in an area 5 times the area of your patio, but it is not the sole source of heat for the space. One last thought, if possible position the heater along the new outside wall facing in toward the original structure. If any of this is masonry the thermal mass will absorb heat when the heater is on and let it out slowly between cycles. This will allow your heater to cycle less often. Regardless, even with no masonry you don't want to be sending radiant heat into glass. I hope you find this helpful.

My wife and I are going full-time in a travel trailer. We look forward to continuous hot water. Thanks for the advice!

I have the 12000 btu unit in a 700 sq ft cabin and it keeps up until the outside temp gets below 15 degrees and it still puts out a fair amount of heat down to 5. I would think it shouldn't have any trouble in the space you are putting it in but it might be wise to keep a back-up just in case.

My garage is well insulated just shy of 900 sq. ft. This little heater will have my garage heated to 60+ degrees with the thermostat barely on the medium setting. That is with outside temps in the low 20's.Great heater,don't buy anything else,

Inground. The 250,000 BTU I bought heats my 9 x 30 pool in Palm Springs quickly (about 2 to 3 degrees an hour with air temp of 75 degrees) and at about 30% less cost than 14 year old heater it replaced. I would guess you would need at least a 400,000 BTU for your pool to get the same performance. A 250 may work but it would have to run much longer than a larger heater. If you go Haywards web site I'd be surprised if they didn't have a calculator that would tell you exactly which of their products would work best on your size of pool.

Our trailer was pre-wired for a rooftop ac. We just installed it & attached to existing wiring. It is designed to run off electrical hookups. If you have a large generator to run your trailer I believe that would work also. We have a Salem 19' LE which is insulated for all weather. Hope this helps.

I was using a 6500 BTU unit for a meat cooler long before I heard of the CoolBot system. When I bought the CoolBot I figured I had nothing to loose by hooking up the old 6500 AC. They recommended a 12-12,500 BTU unit for my size cooler. The smaller unit froze up. It just wasn't enough to handle the colder temps.Go to their website. They tell you the capacity you need, and also the brand and models to avoid. I was about to order a 12,200 BTU unit when I read their data again and they said never to buy that model. It was not sufficient and would not work. I followed their brand rec. and my unit works like a charm. There is about 4-5 years of customer info on the website. Hope this helps.Roy210-508-8600 I was using a 6500 BTU unit for a meat cooler long before I heard of the CoolBot system.

I would look for an infrared "radiant" heat source. If propane works then the previous responder is right. If you need electric then you will want a radiant heat source. The "ProFusion Heat Ceiling-Mounted Workshop Heater with Halogen Light - 5200 BTU, 1500 Watt" is the style I would recommend. Anything with a fan isn't going to be much use unless you can have pointed directly at you, but then you might actually get hot. This 5600W Portable Industrial Heater is a 240volt unit so a place to plug it in can be an issue. The item I mentioned earlier is 110/120 standard wall outlet plug in. If you mounted a couple of those on the ceiling at the end furthest from the house directed toward the house I think you might get what you're after.

I would have to agree w/ Toshi...if you are going to use this for primary heat, you should get a larger capacity tank else you will be RE-filling it ALL the time! :P...I only use this heater as my back-up emergency heat source & I run it off a 20lb (think BBQ tank!) & 30lb (travel trailer size) tank for convenience...one 20 lb tank heating about 1000sq. ft will only last me about 1-2 days when extremely cold out (less than 20 degrees or so), otherwise if the temperatures are 'moderate' you may actually get a few days from a 20lb tank! Hope this helps! ;)

If you are looking to buy this brand, please DON'T. Mine totally quit. They are impossible to get in touch with. The heater can't be repaired. Believe me, I wished I had spent a few dollars more for a name brand. But to your question, a small heater would work in one room, but not the entire trailer. Again, please do yourself a favor and AVOID this brand.

it sounds as if your trailer is not tight. if you are only using this unit to heat a small area rather than the whole trailer, it should work quite nicely. I use mine in a room that has no heat whatsoever and it does the job for me.

Usually consider 30 BTUs per square foot. But this is a general rule of thumb and many other things can effect the heat load.

I use this to heat 350 square feet in Durham, NC. The winters are mild and the unit is most always on the low setting. I would buy the next size up and you can keep it on low instead of using this one with little to no spare capacity. I hope this helps.

Mine is on 24x7 in my trailer, without bad smell. It simply has a heating element. Possible something (small) got in or on the heating element. Manufacturer recommends keeping thing away to assure air flow. Good product for me.

Hmm. Aren't you supposed to put a fanless convection heater in front of the coldest area. A sliding door should be ideal. That's how the heat spreads around because of the differential in temps. That's the point of getting a fanless convection, I thought.

I think the answer depends a lot on the size of the pipe, the severity of the weather, and how often the pipe is used to transfer fluids or if it is under pressure 100% of the time. The other answers all have merit, and the newer heat tapes work better than those 40 years ago. Always insulate and then i recommend waterproof with a layer of plastic (4mil) closed with Duct tape. I did the insulation and waterproofing times two and never went under the trailer again while in Connecticut in colder times.
