It is true that a solar water heater DIY costs much less than a commercial for the homeowner, but what is not so clear is the extent to which the performance is affected by the fact that the system is home.
The cheapest does necessarily worse in terms of performance?
Is it possible to build a system itself that can heat the water, as well as units of professionally designed, built and installed cost thousands more?
The measured results of efficiency below specifically solar water heaters DIY already installed in homes around the world have the answers.
They were measured by system manufacturers use a variety of different temperatures and energy monitors.
If you have built and installed its own water heater solar DIY, please consider making a difference to save the planet by measuring the efficiency of your system and sharing with me, if possible.
