Experience with Solar Heaters?
Comments (113)@solarventi, Hi, sorry, I didnt work it correctly, It is an interesting concept, but I am not getting it>>> bit slow... How do you heat up in winter in Vic when we get very little sun and the weather has turned Artic this year, Main reason I am noticing the cold, especially when working outside. I do have low blood pressure so feel the cold, but the red clothing next to skin works a charm. I would like to understand... I have seen on uTube where they DIY passive heat I liked the pictures but no explanation and these were using exisiting windows .. I this with gap at bottom on outside so cold air comes in and gap at top on inside so warm air into house.... but got to technical for me. And I get confused, as hot air rises and I dont understand why fans are at the top in newer models not at bottom [of heaters] But I would mind understanding how it works.. Am going to check the website, TU very much. I have bats to put in kitchen reno but would like something to attach to the corrogated iron so there is no gap between iron and bats. Appreciate your help and will check again on your site to see if I missed anything :)...See MoreHelp solve a passive solar dispute with my husband...
Comments (16)I would have to agree with envirotechure...and I would look it like this - if it is sunny, warm and no wind and you open the door/window you will be warm and so will be the room. If it was sunny and windy, the wind will cause a decrease in temperature and you will be cold and so will the room, so sit behind the closed glass window and you and the room will be toastie. If it is overcast and cold, you won't get any heat from the sun, so close up the room and put the heating on or go back to bed and snuggle up. When the sun moves and it is no longer heating you and the room, close the window and door and go catch the sun in another part of the house. I think we all do that naturally anyway, it's just common sense. And in a really hot summer, you will be wanting to shade that room to cool it and yourself - the exact opposite. Obviously, if you have good insulation, thermal mass etc etc the effect of heating that room will last much longer than that moment, but you will still want to catch the sun in winter and you will want shade in summer....See MoreNew Off Grid Rural Solar Passive Design for Wide Bay
Comments (69)we're building in Childers Qld (Zone 2) on top of a hill 120m above sea level with no chance of being built-in as we are on a 69 acre block. Quite windy all the time predominately from the SE. All outside doors will be security. Roof has vents in the gables on all four sides so I can leave open to purge heat during summer and close off in winter. Bed 2&3 doors used to be adjacent bathroom door for cross breezes but a layout change in the bathroom meant having its door on the east now. Not ideal but necessary. Dark colour unfortunately is dictated by our very red soil that will stain any light colour so had to go dark, would of preferred light. So I should make my eaves 1200mm all around?...See MoreSolar panels or not
Comments (3)Hi Marjory, Highly recommended, they are becoming much more affordable now. 1.5kW is a basic system, 3kW should create a significant dent in your power bills, and a 5kW should cover most. Most suppliers will provide you with a calculation on payback periods. Anywhere between 3-7years. Unfortunately, buy back rates (your energy pumped back into the grid) for energy suppliers is getting smaller. Lots of things to consider: I highly recommend the SunnyBoy range over inverters Tesla and several others are bringing out battery systems, which increases your efficiency. That is, absorb solar energy during the day, store it in a battery, then use that at night or at other time when peak energy rates are higher. Also, during your "energy saving transition" - consider changing appliances that have a significant influence on energy usage. (see attached chart) - This indicates where the majority of people spend money within their home electricity bills. Increasing the efficiency of your heating cooling, water heating and appliances may be money (or habit changing) well spent. Regards, Doug Perth WA...See More
