Our house needs a heater. It currently has a hole in the roof for the flue and a chimney on the roof, nothing else. Given that Ballan has some rather cold nights (and days) over winter and well into Spring, we will need some decent heat. I don’t want to be relying on fossil fuels for our heating either which means we are quite restricted with how we can heat the house. In fact, from all I’ve read, there really are few sustainable choices; passive solar housing design, houses with high thermal mass (such as Earthships, straw bale homes, earth-bermed/sheltered homes and rammed earth homes) or geothermal heating (like in Reykjavic). These are the only ones I can think of that are truly environmentally friendly heating options.
The normal options would be electric heating which as we all know, can be expensive. It’s also usually reliant upon fossil fuels unless you buy “green” electricity. Gas is still not a renewable fuel no matter how clean it is, well not unless they start using methane. 😉 Wood fires can cause issues in some areas where the smoke pools and it can cause problems with some people with respiratory problems and not all heaters are efficient. There really don’t seem to be any truly viable in all areas heating options out there and unless you have a house that requires no or very little heating, you will need to make a compromise somewhere.
Passive solar heating is capturing the heat from the sun that’s coming through the northern windows (for us here in the southern hemisphere) and trapping it in flooring such as tiles or cement slab floor. However, our house in Ballan is on stumps and technically faces south. We are considering changing the back door to a larger glass sliding door to add greater glass space for passive solar heating but the house, even if it was insulated to the extremes, will just not generate and store enough solar heat to be solely heated by passively solar. We need to look at another option.
We have chosen to try and kill as many birds with a single stone as possible and have opted for a wood burning heater which has an oven and stove-top (so we can cook once post peak oil prices have driven gas to unreasonable amounts), hot water heating capabilities that can also use hydronic heating to further utilise the heat. It’s a LOT of work being done by each piece of wood and we should truly get full use of the heat.
I love the idea of being able to heat the house comfortably, then further make use of the heat to also bake my bread (I bake bread at least 4-5 times a week) rather than turning on the oven. I can use the stove top to reheat soups, boil the kettle and other such things and I already use cast iron cookware all except for a kettle. They are hard to come by.
We are installing solar hot water too, hopefully at the same time which, although it will have a gas booster for back up, I hope we won’t ave much need for it. The house is only 120 square metres, give or take so we’ve opted against a hydronic heating panel for now but we can retrofit that easily enough if we need it.
The best bit is that I believe they are made right here in Australia. 😀
Anyway, today was all about a trip to actually SEE one of these heaters. It’s bigger than I thought even despite all the pictures I’ve seen and after being warned at the small sized oven I was pleasantly surprised at its size. I hadn’t expected a full sized oven but it’s more than big enough for a casserole dish, roasting tray or 2 loaves of bread which is all I ask for. I am also stoked that I will be able to generate my own wood ash which can be of benefit in the garden.
So, one more task is knocked off the list and we will let our plumber (the installer) now we are ready to go. YIPPEE!
