Default Thoughts on electric screen porch heater

We've enclosed our screen porch with EZ Breeze panels and would like to heat it enough to watch TV outside during the winter. We're in Raleigh, NC, so it doesn't get very cold. I'd like to be able to bring it from 35-45 degrees up to 65-70.

Here are some specifics:

Room is about 16x16 with 12 foot peaked ceiling.
Floor is deck boards, so open between the boards and no insulation, about 5 feet off the ground.
8x11 thin indoor outdoor carpet covers floor partially.
EZ Breeze mylar panels provide zero insulation aside from blocking wind.
No venting possible for gas type patio heaters

Multiple, various size indoor type space heaters didn't work at all.

I've looked at some of the box type garage heaters and am not opposed to that. They require running a 220/240 line which isn't an issue. Most are hardwired and I'd prefer the ability to have a plug so I can remove it during the 8-9 months it wouldn't be needed.

Anyone have an alternate thought or suggestions? Anyone used this type of heater that they are happy with?

Thanks in advance.

How about this? Requires 240v.

I recently purchased 4 of them for an outdoor kitchen we are building. Just framing the cover now so I can't report on how well they work.

Have you seen our weather for tomorrow night? 0 degrees Pretty sure my heat pump wasn't designed for that!

I know this probably isn't the solution you're looking for, but one of those cylindrical kerosene heaters would do awesome out there, and you could put it away when not needed. We use ours as emergency backup heat, and it keeps our 2200 sf house comfortable when the power is out. Probably more trouble than you're looking for though for that application.

Do you have natural gas (your porch, not you)? If so, we put a small NG heater in our sun porch 12x24 and while it doesn't get balmy in the winter, it makes it comfortable. We're south of you so not quite as cold.

heating a non insulated,non air tight space is not going to work very well, unless you seal it and insulate it

good place for a fire pit with hood and pipe or wood burning heater with pipe going out the top or side.
all except electric is going to get smelly at times

The challenge is the carbon monoxide for the propane type heaters - those would be great otherwise. It is mostly enclosed, so the venting would be risky.

BH525 - those look interesting. I am checking to see how many might be needed.

Anyone use the box type heaters like this one: https://www.amazon.com/Fahrenheat-FU...=garage+heater

Mr. heater and quite a few others offer non-vented lp and natural gas heaters that have a low oxygen shutoff to avoid this being an issue. Add an off the shelf carbon monoxide detector and you are set.

The radiant heaters you use on top of a propane tank work well and would be portable. A nicer looking one would be the patio heaters. There are some wall mounted propane heaters that don't need power and you could run the propane hose under the deck and leave the tank outside.

A Mr Buddy heater is safe for interior use and can run off a 20# and larger tank. I think that would be a cheaper temporary alternative that a big ass electric heater

You can make a hardwired connection into a plug. Just buy a plug end and receptacle and there ya go.

Get a radiant propane/NG heater. Radiant heats you, not the air. Much more effective. Many are designed for no exhaust vent, so can be used in semi-enclosed areas. But be certain of that and get a CO monitor.

I just installed a smaller version of that heater and it works good. The one you listed was more than I needed but would be my choice in your situation.

So, Mr Buddy has found the secret to combustion without CO? Just askin ...

Your patio will be fine with propane or ng heat.

There is a TON of makeup air available through your deck boards.

Propane heaters made for indoor use are perfectly safe anyways.

Propane burns so cleanly the main problem you have when it's enclosed is moisture.

Had the wall mounted (blue flame) propane heaters in our hunting cabin for years.

propane/NG devices meant for this kind of service create almost zero CO.

Gas stoves are not vented. No one fusses over those.

I just installer a Mr. Heater vent free natural gas heater in my garage. You can always install a carbon monoxide detector. Your floor boards will provide more than enough make up air. It needs no electric and comes in various sizes. I had a coupon for $20 and it was $10 off, so I paid $89 plus tax for a 10BTU unit. Mine is natural convection but you can get a 30k unit that's good for 750 sq. ft. with a fan for $179 from Northern Tool.

Some great feedback here. Still open to other ideas.

I was using one for 2 years in my garage it worked o.k. but you could smell it occasionally. Multiple times when switching from low to high the unit would leak gas and flame up right where my hand was. Last straw was when I spent several hours trying to locate a refilled tank it was a cold day and the home center was all sold out. Fire department restricted a neighboring town from even stocking propane on the premises. Decided to just go with electric and be done with it.

Since that room is covered you might be able to tack up some foam board from underneath to help with any drafts from below

We have a 600w IR heater in the Tiki bar and the Admiral is OK with it. It really just heats you when you are in front of it

I used one of these as my only heat when I lived in a yurt for a few years on my property. I had no utilities so no power choices, etc. Kerosene seemed pretty cheap to me at the time.

No BS, sometimes I would even carry it to the outhouse in the winter. That was morning poopin' in style!

Some nights it really sucked but my yurt was only a glorified canvas teepee and would leak in our pounding rain.

Pretty darn good heaters either way.
