Well where I am living, you would need a heated greenhouse to maintain a working temperature 68 F and above for more than 3 months of the year. Also, even unheated greenhouse space is expensive and you want to use it for food production to the max.
Using a heater to run the biogas digester would only make economic and 'green' sense if you have a heat source powered by solar, wind or another 'clean' say carbon-free energy source. Our grid electricity is partly hydro but still some fuel is burned to make up the difference in our needs. So even if you could afford a heated greenhouse space for biogas, burning fuel to heat the digester would defeat the purpose.
