Anyone have any experience/ideas on a friendly hot water system ?? We will be bathing neked under the stars, as nature intended, so getting the water hot the same way might be nice.
We are about to build a small bathroom on the bungalow at the farm....in fact 2, one for the workers is already commencing.
I figured 5 months of bathing in the river morning and night can come to an end and give them a little luxury.
For the workers it is a simple 5m x 1.5m bathroom split into 2, toilet and shower sections.
the shower section we decided upon old fashioned thai style instead of any fancy shower system.
We have a tin sheet roof, rainwater collects and feeds into a large 2m x 1.5m x 2m tall tank with open top and the overflow from this feeds into a small wash tank beside the main tank. Both have drains and taps etc. This enables us to make use of the rainwater during the wet season and then pump from the river into the large tank once a week during the dry season. To me was the most efficient way to enable both.
The toilet is concrete rings with the rings sitting underneath one of the toilets walls, this allows a hole in the top of the pit to be able to pump out the shit if ever required.
Waste water from the shower and washing goes into a drain which runs to a reedbed area on the side of a small incline which drains away to a flat area about 30m from the river.
As for the other bathroom for the bungalow, I want an efficient and friendly system. At first I was going to setup 1inch black PE pipe on top of the concrete water tank behind the bungalow. But problem here is how do you get the water continualy up to the pipe for solar heating ? It can be delivered by gravity, but I do not want to have another pump just for this.
And the use of a pump kind of cancels out any good done by using the sun to heat it.
Any ideas ??
