A lot of reasons exist why solar water heaters should be built. Most will simply want to have smaller bills while others are actually thinking about protecting the environment and cutting down on fossils and trees as supplies. The truth is that a water heater can really help out any home out there. Many good variations are currently available for everybody. We recommend that you choose a solar water heater that is passive and will not need an extra energy source to work.
When beginning building solar water heaters you need to think about the personal water needs that you have. A regular person will use around 30 gallons of water daily. Costs can be reduced if you are thinking about looking for discarded electrical heater tanks that have good sizes to suit your needs. Think about the location of the new heater. It should be placed outside the house with it facing south so that good sun ray exposure is possible.
The tank must be painted black so that more sun energy is to be absorbed. Also, you need to build or buy a good plywood box for the water tank. It has to feature an incline in order for the heater to be placed in an upright position. In order to maintain a small level of energy loss you will need fiberglass insulation for the interior of your box. Then just install your water tank.
Different pipes and plumbing fittings have to be linked to the bottom of your tank. They are to carry water from home to a solar heater. Then you can connect another set of pipes from the heater top. Such pipes will be linked to a simple heater that you already have attached inside the home. It is highly recommended to own one in order to properly have backup units and maintain water warm for longer periods of time.
Exposed pipes have to have insulation so that they do not freeze during winter. Fiberglass is the most effective but alternatively the use of insulation foam also gives good results. Now you do have to cover the box by using clear plastic and/or window glass. When doing this anyone can easily keep the heat inside the box.
