Mr. HeaterMHVFRD10NG 10,000 BTU Vent-Free Radiant Natural Gas Heater For Office, Home, Garage, Patio, Sunroom & Cabin - White

Came packaged well with easy to understand instructions. My 87 year old mothers furnace doesn't keep up when the temperature drops below 20 degrees. I was able to install this in her living room where she spends most of her time and the radiant heat can be felt 15 ft away where she sets. She left it on during the night with no reservations and it kept her room comfortable. Very happy with the unit. I've had same brand in my garage for years and have had no issues. Worth the money.

Works great

Nice quality, really does the job!

I have an insulated shop that already has a mini split heat source, but I don't like the whole shop to be too warm, so I'd gotten into the habit of running a 500W electric space heater right next to my computer desk area during the winter. If I ran that 10 hours in a day, that could be almost a dollar in electricity. So I decided to buy this little 10kbtu natural gas heater to get some cheaper 100% efficient heat.I was worried it would be too powerful for my needs, but at 4-5ft away from where I'm sitting, it is perfect. Despite being a radiant heater, most of the heat does indeed go straight up, and only a portion is projected outwards.The heater is bigger than I'd prefer (quite a bit larger than an 18kbtu Big Buddy heater), but it is ok and the larger steel frame probably makes it safer. I'm currently running this heater with a 40ft 1/2" flexible gas hose, but a 3/8" hose would be fine. I measured the gas flow at my gas meter and calculated 9,932btu at the high setting, and 7,777.5btu at the low setting for this 10kbtu heater. This is with 6 inches of water column for the gas pressure. I do wish the low setting was a bit lower (5kbtu would be great).So given that this outputs way more than my little 500W space heater, I'm still spending about a dollar a day in gas to run this for 10 hours, but I'm getting five times the total heat output. I expect this heater will easily pay for itself this winter.I also like having gas heaters on hand for emergency situations where we lose power or a furnace goes down during the winter. This heater will serve that need perfectly and I plan to order a couple more (probably 20kbtu and 30kbtu for a whole house backup heat source).

Arrived with grate cracked and i didnt open it till winter when i needed it. It surges and blows its self out. Too late for a return i guess i havent heard from anyone i have messaged. Open when you get it and check it before your time runs out

Heater is okay. Ordered on Wednesday, told would be delivered in two days on Friday. Came on Monday the next week. I would have bought locally if I had known it would take this long, as I needed it to replace a heater that quit working.

Easy install

I already had the next size up that has the temperature control and when I decided to buy another one, that one was no longer available so I opted for this one. It only has two heat setting: Hi and Low. When heat isn't need it can just be set on pilot. I use this to heat a space 10 X 25 that is well insulated. When I come up here this winter it's generally 58 degrees as the heater isn't on over night. The other heater is downstairs so some heat seeps up here overnight. I turn this onto Hi and very quickly have to turn it down to low as it heats up so fast. I came up here today, forgot to turn it down to low as fast as I generally do, and it is now up to 78 degrees after about 35 minutes. So now it's turned down to pilot. That's typically how it has been here this winter where our nights have generally been near zero every night for the past couple of months. If you are going to be in the space while running the stove making the adjustments isn't a problem but you can't walk away with this type of stove as it will continue to heat and it can get pretty hot. It's like having a wood burner and having to chuck in a piece of wood now and then, or if it's getting too warm, letting it cool down for awhile. If you need one to have a thermostat on it, like my other model, they work perfectly, but this model doesn't do that. I had a Rennai vented heater here in this space for about 20 years and it finally had to be replaced. This model isn't vented, so you have to be aware of the potential danger in accumulated gasses. I handle it this way: I have a wall vent here and downstairs and both are on a timer. Up here the vent blades are smaller so I have it come on more often which is 8 times a day for five minutes. There is a lot of fresh air that comes through in that five minutes! It's necessary to have some opening to the outdoors though for the vent fan or it can't pull air through. I leave a downstairs window partly open which more than does the job for both the downstairs as well as the upstairs. You don't want the combustion gasses to build up inside your space. All in all, this is definitely doing the job, and for the low price is worth buying.
