First, nothing is efficient without good windows and insulation. Aside from that you have alot of options but some are better for the layout of the house and the area you live in.
Pellet stoves are very good nowadays and are very efficient. You do need a place to store the bags of pellets, and they do need cleaned once in a while, but you can get them where you see the flame. (very romantic) Good heat.
I just built 4,000 sq ft (2,000 on each level) and went thru the “what to heat with dilema”. And the winner is…
Rinnai heaters. They are AWESOME. Gas or propane fueled, direct vent out a wall with a minimum clearance of only a foot from any door or window, and very efficient. I did build with Logix foam blocks and have R-50 in my ceiling, but I went thru a winter here with temps sometimes at -25*F with only one heater hooked up upstairs on one side of my house. With thermostat at 72, farthest room upstairs (master bath) temp was 69 and it kept my downstairs(unfinished) at about 60 and warmer. Not bad for one heater. I used the larger Rinnai, cost $1400. They pressurize your house as they heat so the heat feels like a blanket around you, very nice heat. Will eventually have three (2 larger, 1 smaller). 1 larger for 2,000 sq ft upstairs, 1 larger for 1,200 sq ft downstairs, 1 smaller for 800 sq ft mother-in-law apt. Total cost of $3600. These units humidify also.
Forced air system bid was $7500. But you can add AC, humidifier, and air filters to this system.
Also if you are redoing floors, look at in floor heating (hydronic or electric). You won’t want anything else for your own house once you go that route.
To many options and good/bad sides to all the ways of heating without knowing more but I’m totally happy with my Rinnai’s and you would be happy with them also or pellet stoves. E-mail me personally if you have more specific questions, or ask here if you want. I’m not a heating guy but I looked at almost everything, so I’m not jaded to any one way.
