The concept of a variable speed pump is pretty simple when a centrifugal pool pump runs at a slower speed the resulting energy use reduction is the cube of the speed reduction resulting in an exponential savings of.
How fast should water run through my pool solar panels.
A solar collector the device through which pool water is circulated to be heated by the sun.
However when you heat pool water with solar panels before the cleaned water returns to the pool it passes through pipes leading to a solar collector.
The system also requires a check valve flow control valve and a sensor in order to keep the pool temperature in check.
In fact the opposite is generally true.
This advantage reduces cost and you can consider it a form of energy conservation.
A filter removes debris before water is pumped through the collector.
Aiming for peak water temperature at low flow may be a valid concern when using solar heaters for domestic hot water but that is not what we are talking about here we are talking about heating a swimming pool.
Solar pool heating panels work most efficiently when the difference between the panel surface temperature and the pool water is greater.
Each gallon of evaporated 80 degree f water removes about 8 000 btus from the pool.
Solar pool heating systems use the existing pool filtration pump to circulate water so the selection of a pump can have a profound impact on solar pool heating performance.
Most think that running water fast through solar panels will not let them heat the water adequately.
So your goal here should not be trying to make the return water as hot as possible by lowering the total flow instead it should be to transfer the most btu s into the pool itself.

First pool water is pumped out from the pool through a filter then to a solar thermal collector where solar energy heats the water before returning it to the pool.
You may decide to increase the surface area of your solar collectors just so you don t have.
Actually solar pool heating is the most cost effective use of solar energy in many climates.
How fast should i run water through my solar pool heating system.
When you use a regular swimming pool pump water is pulled out of the pool pumped through a filter for cleaning and returned to the pool.
Flat rate time of use tou either of these can be used to power a hot water element in conjunction with solar hot water solar pv and possibly a controlled load tariff see below.
In australia there are two primary types of electricity tariffs.
Your pool system already includes the pump controller and filter along with pvc pipes that route the water flow.
Type of electricity tariff.
Simply break into the pvc line after the filter and run a couple of flex hoses or pvc if you prefer to the solar collector panel which you can lay out on the ground or set against a hill to achieve some tilt toward the sun.
Example of a tankless water heater by rheem.
The water coming out of the jets feel like the same temperature as the pool water there is a common misconception that the water returned to the pool should be and needs to be significantly warmer than the pool water.
You do have to place covers onto the water and then remove them which can be a hassle.
You can heat your pool using solar power.
