It seems that the iPhone SDK for Snow Leopard (downloadable at /iphone and released in June 2009) installs outdated MobileDevice Extensions that are incompabile with the final release of OS X 10.6 Based on usage this first winter a typical 1000L oil tank will I believe last us for two years between refills.I ran into a pesky problem after I installed the iPhone SDK (before that I installed XCode 3.2 from the Installer DVD) under Snow Leopard: My iPhone/iPod Touch was neither detected by Xcode nor by iTunes anymore. I am in Scotland and we use around 2.5L of oil, and a basket of wood a day in the depth of winter. The oil is typically only to keep the background temp overnight, provide our hot water requirements for showers in the morning, and any daytime running before we start the wood fire. This heats up a thermal store like yours (by gravity feed), but I also have a thermostatic backup oil fired boiler that cuts in if the wood burner isn't running or isn't providing enough heat. My primary heat source is a wood burner stove with wrap around boiler. The concrete was vibrated in using a hand held vibrator whilst being levelled.Īlso I have allowed for thermostats in a number of locations, with electrically controlled valve actuators as well as the pump start up to control it. I laid my own floor, in 1.5m wide strips using temporary edges to run a spreader bar along. We are living in the house and the system works great. There are a few micro cracks, but I will be laying a tile isolation mat to ensure these don't carry through to the tiled floor when I finally get around to it. I decided to reduce the thermal mass of mine (to reduce heat up time) so I only laid a 40mm slab, to do this I decided to reinforce it with chicken wire. I also installed my own system and congratulate you on a neat system. Wouldn't it make more sense, for comfort, to reverse the direction so the hotter temp water is coming into the center of the rooms and the colder is going out around the perimeter, or, is it done the way you have it because the colder temp of the room would be around the perimeter because of exterior walls and windows? Again, good instructable! The systems depend largely on radiant heat transfer - the delivery of heat directly from the hot surface to the people and objects in the room via infrared radiation. I have a question about the flow direction of the water. The hydronic heating system should be flushed to remove and flux or solder that may be mixed in the water. Radiant heating systems supply heat directly to the floor or to panels in the wall or ceiling of a house. Not something that is easily, and inexpensively done, as an afterthought. If I were to have another house built, I would have a heated water floor system included, as my feet are always cold in the winter. I have needed to refer to those photos often over the years. I did the same when my house was constructed so I knew where interior pipes and wires were run. I, too, took plenty of photos as the system was put in incase I needed the info later. I appreciate your instructable and your undertaking such a project. Now that I'm retired, I only turn it on when we get a freezing rain that leaves an ice coating on the driveway. I had a heated driveway put in a number of years ago.yes, it's expensive to run but at the time I was concerned with getting to work on time and since my garage faces north, it wasn't uncommon for the bottom of my garage door to get frozen to the cement making it impossible to get my car out of the garage. With me doing all the work, the total cost including everything involved was about $1,700.Ī shorter version of this story originally appeared on my blog: Wildcat Man.

I bought a spare pump just in case of an emergency, and the only other component that can wear out is the water heater which I made sure is easily accessible. I mentioned that fact to our electric company energy expert and he said, 'Wow!' He meant that in a good way. And as for efficiency, in our 980 square foot well-insulated house, we average 33 KW a day during the coldest months in western Oregon. There is no hot air blasting dust from vents, and no more feeding a wood stove and having a house that's either too hot or too cold. There is no noise other than the quiet hum of the little pump and the usual water heater sounds. The inside of the house feels like a nice day all winter long, staying at a consistent 68, our chosen setting. The pets have figured out where the supply pipes are and love to lay down on the nice warm floor.
