I’ve got a solar hot water system (i.e. solar thermal) rather than a heatpump that I want to use this kit to monitor the energy being delivered off the roof.
Is this possible ?
More info.
There is a small fixed speed circulation pump and two pipes connected to the cylinder: one at the base that has the colder water that flows out of the cylinder to the pump (which delivers it to the panels on the roof), and another return pipe about 25% of the way up the cylinder where the warmed up water is returned. A controller measures the temperature at the cylinder and roof to control the pump on/off.
I’m interested in measuring the actual performance of water leaving and returning to the cylinder :
- to ensure system performance does not degrade over time, and
- for curiosity’s sake e.g. payback period etc.
