I ve been following your threads. It's nice to see a fellow ecorenovator enjoying the power of the sun. I was looking at your results of doubling your living space and reducing your power usage by almost half. Impressive.
Another ecorenovator is just starting to understand the power the sun wields. Geo-NR-gee is playing with some flat plate collectors and making steam. Soon he should be harnessing that heat and hopefully heating his living space. All for FREE.
Here in Canada the summer has been consistently warm. We have a ground source heat pump which is a water to air unit so the humidity is controlled and our cost to air-condition is very very low. Another big plus is we are essentially storing heat in the ground for the impending winter.
The solar hot water provides 100% of the domestic hot water. Now that October is here and night time temps are dropping into the negative numbers the solar hot water is heating the concrete floors keeping us very comfortable. As the weather becomes increasing nasty and the sun disappears for weeks at a time we resort to a water to water HP to heat the floors.
Our cost for operation of air-conditioning maybe a little less Kwh per day would be around 15 kwh. However the price per Kwh is 0.18 Euro. And we understand another sizeable increase is coming in Nov. We are conditioning 330 sq m.
Kudos to your efforts in harnessing the sun and phase change of gases.
