Useful homemade for owners of cottages and private houses, which will always provide hot water. Make her do it yourself from improvised means is very simple!
Water heater - a device providing solar heating of water in the country. It is a home-made solar collector, which consists of two thick-walled PVC pipes with holes in which plastic corrugated pipes of black color are glued with sealant (white can be painted with black paint from a spray can). The tubes should EASY enter the holes. Plugs are also glued to the pipes. Wooden is not very good, as the tree changes in size over time - it shrinks and soaks.
Design of a homemade solar collector for heating water
The design of a homemade solar collector turns out to be similar to a heating battery. An opening for bleeding air may be provided on the upper pipe. It is mounted on any slightly heat-conducting base (for example, on a chipboard plate). Closed by an old frame with glass - a lot of them are now thrown away. The entire “sandwich” is hung next to the shower barrel and connected to it with hoses.
It would be nice to provide a pair of taps for hoses - so that the water heater can be removed if necessary. If you wish, you can rotate it behind the sun, or at least put emphasis under the lower edge of the structure for a more perpendicular incidence of sunlight.
Draining warm water from a barrel in a shower is certainly better with a hose, the end of which is fixed under a float and floats in a barrel. If you wish, you can even put a mixer for warm and cool water, since on a hot day the water in the barrel heats up very much.
