I hve a building of about 2200 square feet per floor and 2 floors. Id like to install heating system that doesn't require all kinds of retrofit.
I was considering 2 pellet stoves and was advised against them due to care nd maintenance needs.
I am hoping I could use a gs system. Anybody have experience with ventless gas heaters in spaces like I seek to warm?
The heater will be on and off as we occupy the studio space in winter nd workshop. I don't need much heat on the ground floor since it maintains good conduction from the foundation until mid winter, then the "heat sink" of the subsoil goes away.
In the ground floor Ive used a kerosene "Salmnder" (65K btu) and it does a good job but I don't want that noise that a salamander makes .I like to listen to CD's and audio books

@farmerman,

Since no one with experience has responded, I'm going to give you some links to read...I know, folks hate when I do this. But, if I don't have personal experience, it is one of the ways I try to learn so I might be of help.

This is pro-ventless from the industry

This is a long article from Consumer Reports on various types of space heaters, including ventless

@farmerman,

It isn't gas, but what about portable baseboard heaters? You could install enough to warm the entire space and adjust them individually according to use and need for warmth.

BBB had them in her condo years ago when the cinder block walls required something portable. Just two of them (with thermostats and timers) strategically placed in a bedroom and living room were enough to keep the two-bedrm condo toasty warm in each of the rooms as needed.

@Butrflynet,

I don't hate it at all. As I mentioned, it's kind of nice to be spoon fed at times, and you find stuff quicker than I ever would.

@Butrflynet,

we have some of the oil filled portable baseboard radiators in a florida room (It was an old rear porch that we had enclosed and walles and insulated. Its full of huge windows so the basebords fit nicely. They are terribly xpensive to operate even with our "Shopped around" electricity rate.
If we have months with company in the winter, everybody loves living out there an watching the deer and birds. It really jcks our electricity bills up to 6 and 700$ a montg. NAaahh.
Id like to stay with gas even if I need to install a small furnace. Our gas prics have been plummeting and I can float or "lock in" prices for two year plans now. I cant lose with gas.

@Butrflynet,

PS thank for the consumer -like links. Im especially interested in the "Againsts". I decided against a peelet stove heater because they are so damn finicky an the reviews I finally found had the damn thing either cleaned weekly or they lose efficiency quickly.

I've used ventless gas heaters to supplement the wood stoves in our cabin. If you have the clearance I found the radiant type to be better to my liking than the convection units for living spaces and light shop (low dust) areas.

@raprap,

radiant being without blowers and just a huge blinding gas heating some kind of metal parabola or some shape like that?

The second floor has rather high ceilings aso Im going to need at least 2 fans. Ive made a budget of like 6K and I wanna stay within that (not including a buried LPN gas tank cause we live far away from any nat gs lines)

@farmerman,

Not parabolas..they use ceramic plates to burn gas (propane or natural gas depending on the orifice). Units come in various capacities (max~30,000 BTUH). I'd recommend using ceiling paddle fans to distribute the heat in large rooms with high ceilings.

@raprap,

Im going to want at least a 50K and a rapid warm up with a remote start up and a thermostat because the rooms wont be occupied all the time. .
I am planning to install ceiling fans anyway because Ive seen from other rooms that heat loves to hang out at the room peak
HAve a Merry Christmas rap.

@farmerman,

For my larger areas I had more than one--and they're available with thermostats.

BTW the only noise they make is a heat ticking when they start up.
