Solar Powered Water Heater

This water heater was made to keep our above ground pool warm to help teach our children to swim during lockdown. Now I am trying to improve its efficiency and sharing this info with you.

Newest Info at the Top


This has taken some time to put together, where I needed just the right weather to show all the data clearly.

I've put all the information into graph form from the raw data and shared all this in a PDF document



Plus my latest Video explains through this experiment and shows the truthful performance of these systems.

Pool Temp Logger?

It's all built and installed.

There are now 10 temperature sensors placed at various points on the equipment with readings sent to the receiver in the house, plus this data is logged to an SD card at the transmitter side every 15 seconds. I will now be able to track exactly what the system is doing and find the most efficient use of the solar heaters. I'll make another video with this data.

Plus when the panel temp drops below a set temp the pumps turn off.

I will share the code on GitHub once finalised.
