This is a Grandio Ascent in 8x8 feet. I have both ventilation and humidity control set up, next is heat. I'm considering a Williams direct-vent propane furnace. Does anyone have any experience with this?

Welcome to NGA, @Neuraleanus -- and congratulations on your new greenhouse!

I'm not at all familiar with that type of furnace, but it might be helpful if we knew where you are located. Smiling

I'm located in southern Wisconsin, zone 5b. ACF greenhouses sells the Williams furnaces and from their website I figure a 10,000BTU capacity should suffice.

Aha! Wisconsin is my 2nd favorite state! Big Grin

How are you planning to use the GH? Will you be heating it all winter? What sort of plants will be in it? I'm all ears!

I would like to grow both tomatoes and bell peppers year round. So, I think this means a minimum temperature of about 40 degrees F and 40 percent humidity (this is a guess). I have the greenhouse wired for 110VAC and with a water line which will be soon buried just under the grass. The greenhouse is too far from the house for electric heat, natural gas install is too expensive, so this means propane.

By the way, I like your picture, we currently have three cats living with us.

Thanks, the photo is of my goofy cat Ziggy.

One thing to consider is that there are other factors at play besides temp and humidity for growing things like tomatoes and peppers throughout the winter -- mainly, light. I believe you will also have to provide additional lighting to get those plants to flower and set fruit during the winter. However, you can certainly extend the season and get fruit that has already set on the plants to continue to ripen.

There are also a lot o f things that you can grow -- or at least maintain -- during the winter with only minimal heating. 'Four Season Harvest' and 'The Winter Harvest Handbook," both by Eliot Coleman, are both excellent references!

Best of luck to you, and I hope you will continue to keep us informed about your progress with the greenhouse! Thumbs up

The Williams propane heater arrived yesterday. The first step is to make a mounting bracket from some aluminium bar.

The heater is installed, but not yet operational. Tomorrow I'll put in the thermostat and after that I need to have a plumber hook up the gas.

I hope it will be a LONG time (relatively speaking, anyway) before you need to use that heater this year! Smiling

@Neuraleanus I am interested in how your direct vent propane heater did during the winter. Were you pleased with its performance? What do you see as the pros and cons?

Besides the heater, have you done anything to insulate your greenhouse?
