I have some 14x14 rooms that have no source of heat.
Originally, I had purchased five 115-v LG window units which were capable of heating and cooling. (LW8021HRSM) In theory, they're units that can cool 320 sf--- but it wasn't until after they were installed that I realized they were only meant as supplemental heat, not as a primary heat source.
When the cold snap finally hit, the temps dropped to the 30's and 40's, and we started using the heat, I realized pretty quickly that it was inadequate for my needs. I'd set the thermostat for 80*, and the air coming out would be 60*. Brrrrr.
So-- now I'm scrambling to find some actual 115-v primary electric heat to at least get me to March. Originally, I had tried CHA, but couldn't get anyone to quote me what I was asking for. Then, I tried getting mini-splits, and they were just as expensive as the CHA. Then I couldn't put my hands on the actual dual units I was looking for that had the best reviews--- so I ended up driving hundreds of miles all over southern Oklahoma and north Texas trying to put my hands on the few dual units that were available. Except they don't do what I thought they did.
So if I was to find a stand-alone/portable electric heat source that plugs into a regular wall plug, and only care about heating a 200-sf space--- what would be dependable? Our winter temperatures are usually in the 30's-50's for most of the winter, with the occasional 10's and 20's during the coldest part, and very rarely getting into single digits/under zero. --137.118.xx.xxx

Sounds like you wasted a lot of time.
Best you can do is the small ceramic heaters or oil filled heaters.
With you normal household current. 115/120 volt you are limited to 1500 watts of heat.
No matter what package you put it in. 1500 watt of heat is still 1500 watts.
Put it in a 120 volt mini split, a small $30.00 heater for Lowes, or a larger unit which is just a bigger cabinet.
It is still the same amount of heat. --76.104.xxx.xx

I am going to try one of the milkhouse heaters this weekend. I will let you know the result. You can look at my post below "heaters" to see the one that I am referring to. --73.113.xxx.xxx

Indeed. This year was crazy for getting anything done. Everything took (at least) twice as long, and cost (at least) twice as much. This renovation started January 4th. It shouldn't have gone past the 4th of July in a normal year, but this year, I was lucky to be anything near move-in ready by Halloween, and was still troubleshooting the weirdest odds and ends into November.
On the plus side, I'm hoping I can squeeze in one final renovation between now and Christmas. --137.118.xx.xxx

What Homer said. We installed one in an attic space on a rehab we sold years ago. Was installed in the middle of the room on an inner wall. --75.11.xx.xx

I had this problem with converted garages into a pool house. For changing cloths, showering and guest quarters. I had the availability to use any of many sources, natural gas, propane or electric power. I decided to first try 120 volt electric heater.
I purchased several heaters that were designed to be mounted on the wall, away from guest clutter and a potential fire.
These wall mounted heater all had booster fans to circulate the air and thermostats to regulate the heat. They were all rated around 5,000 BTU -- small output. A wall gas furnace can range from 8,000 to 15,000 BTU's -- double or triple the heat of an electric heater.
I hate baseboard heaters. I'm not a fan of free standing heaters with guests or tenant use, but here are some really nice working. Here is one of my best choices for tenants with room ranging from small up to 18x14

The future is to upgrade insulation so to minimize heat loss and heat gain then the HVAC can be downsized. In the house starting to spray foam walls and ceilings where this year installing vents on rafters then going to seal up rafters to isolate from attic so heat loss and heat gain is reduced. Tonight it is slightly below freezing where this year using high efficiency gas furnace less. Most mini splits use 240 VAC as there is more wattage required where 120 VAC is going to limit output. Better quality units will heat down to lower temperatures. In Germany they are installing insulation on outside then stucco over insulation where very buildings there was brick. Sooner or later coal fired power stations are phased out then the cost of electricity is going to go up subatancially. Radiant floor electric heat for a larger room where 240 VAC required which is mor efficient then other forms of electric heat. Also upgrading windows and doors will reduce heat loss and heat gain as well. Since installing a new front door and storm door the heat loss is reduced as now air tight as possible. Here there are net zero houses then have very low Evheat loss and heat gain where the walls have R 50 and ceiings have R 90 along with triple pane low E windows where solar provides power and heat source. If have a thermal camera then will able to see where heat loss and heat gain is. --68.69.xxx.xxx

Deanna, here is an update for the milkhouse heater that I am trying.
The upstairs to my shop is approximately 256 sq ft as it is 16x16. It is 29 degrees outside. The temperature in the building was 39 degrees and one hour later, after turning on the new heater, it was 52 degrees. So, the temperature rose 13 degrees in one hour. It is very similar to my older heater and thus I will buy a few more of these and place them throughout my project house.
BTW, these are insulated walls and ceiling but the downstairs is not being heated and has a garage door to where air comes in to a small degree. --73.113.xxx.xxx

I was looking at wall mounted panel heaters but have not tried them. They should easily be found at Lowes.

Deana, I suspect that you have good reasons for avoiding conventional Central heat and air.
The type of heat/ac unit often found in hotel rooms will get the job done. However, your requirement that it plug into your existing wall receptacle raises concerns that the circuit has too light wire/ breaker to handle a unit that is adequate for the job.
This job will likely require an electric circuit upgrade.
Primary Electric Heat (by WMH [NC]) Posted on: Nov 19, 2022 9:32 AM
You've probably heard me say that we rely on through-wall heat pumps by Amana (similar to PTAC units in hotels, but smaller - easier to cut and frame out the wall around them. About $900 on ajmadisondotcom (at least $100 more on Amazon and Home Depot.) They are 220 though. We've never found anything 110 that is sufficient.
We have them in many many units, sole source of heat and air, and no one complains about them ever. It's kind of shocking because some tenants will complain about anything, as we all know. We actually get more complaints / issues / problems with the central units. --50.82.xxx.xxx

VTACs are also a installed in hotels. They are vertical units. I am looking into them for an ADU, as I think I can run some ducting with them. They should also be tax efficient, like PTACs. My understanding is that they are considered appliances, so you can deduct the entire cost of them during the year of installation. I am not an accountant. --154.21.xx.xxx

True, the stucco over exterior insulation originated in Germany, but it has been used on this side of the pond for a very long time. My father started installing it here in Indiana nearly 50 years ago. It's called EIFS: Exterior Insulation Finish System. Some people call it synthetic stucco. A great way to add insulation to new or existing homes or commercial buildings.
Sorry for going off on a tangent. It felt like a good time for an EIFS commercial. --107.141.xx.xxx

Find a way to have a 220 outlet and cut into the exterior and frame an opening for a boxed cool/heat pump, like a hotel PTAC but this is off the floor in the wall. --76.190.xxx.xxx

Most jurisdictions will not permit space heaters as primary source of heat where have to careful as make sure wiring is not overloaded. Use only when working along have a fire extinguisher on hand. Drywall renovation will create a lot of dust where that can be a real problem with a forced air furnace which can clog up heat exchanger. If water is drain out then that will minimize pipes freezing up. Air filtration will cause a lot heat loss in a building where sealing up would reduce heat loss. In the house there is garbage moldy fiberglass insulation where when some walls were broken out then spray foamed along with installing a bubble wrap where heat transfer from wooden studs were reduced along sealing up tape then the wall was completely air tight. Here the government insulation programs push fiberglass insulation which is the lowest cost but after a while develops air pockets and mold. Roxul batt remains constant along no mold problems. Water has four times the thermal conductivity of air where once there is condensation where the insulation is useless. Once at the HD people are still buying that garbage insulation. I would give them for free the fiberglass insulation that taking where in the ceiling there is less mold but some is still good. Solid board insulation is ideal for basements where sealing up then drywall. --68.69.xxx.xxx

Do you have an existing dedicated 115 circuit for the wall unit? Is the house wired for 220?
If so it is fairly simple and cheap to change the dedicated circuit to 220. Making this change would double your available amps using the existing wire. Code MAY require a new 4 wire run, so check first.
If you have 220 available, I'd definitely use it. Much safer. Does not overload the wiring and overheat it. --216.218.xxx.xx

Scott IN, I have been thinking about this stucco insulation for a long time, as in inventing it. Glad it exists. I think this is the answer to staving off any energy problems and avoiding the solar panel issue here in NJ where the Dems are in charge of everything. I think people won't like their houses looking funny but that's OK. I have distressed brick and a Dutch colonial and dad had it built to look like houses in a nearby park, Washington's Crossing. I will look up your Exterior Insulation Finish System and probably get it if it doesn't smell bad or have any emissions.
Isn't Deanna the one with the windmill and panels who lives way out in Nowhere TX? How about propane for your heat source with an additional heater and a tank? You are trying to kill an elephant with a fly swatter. --71.188.xx.xxx

Wnat is done with exterior insulation is solid board insulation is installed over brick then stucco is installed over. It is possible to paint what colour that suits people. No emissions as stucco will seal everyting up. Air filtration is the greatest source of heat loss where a air tight building will keep heat in winter and heat out in summer. The future is using less natural gas, less oil not some political donation to a political party that is going backwards. It is common here every once in while people vote for a provincail Socialist Democratic Party where most never last more then four years then voted out. I remember the one term Socialist Democratic Party was voted in the province of Ontario then next election the Progressive Conservatives came in with a majority. Those fools listened to leftist hate groups who do not believe in private sector ownership of rental housing where they brought in penalties for energy conservation where tenants could apply for rent reduction under rent control if annual operating costs were reduced where one November 20th day 20,000 jobs were lost where the building owners cancelled plans to replace boilers with high efficiency gas boilers where most of job loss effected tenants who never voted for that regressvie party again as what good is rent control penalties if you do not have a job. Rental housing here employs local people with good paying jobs. Around the world regressive governments last one term where never elected again. Last provincial election here the Liberal leader did not even win a seat in riding where that was how was how unpopular the Liberals were in Ontario. He went on to be elected as a mayor where a lot of leftist policians do that. Like any private for profit industry people look for reducing operating costs where the building goes up in value along with a lower emissions More insulaiton the HVAC system last longer less breakdowns as there is less wear and tear. You can not reason with stupidity of the leftist nutcases. --68.69.xxx.xxx
