How to Install a Solar Pool Heater
Solar pool heaters are certainly the most cost-effective way in pool heating mechanisms available out there, and they work just as well as any other heat pump. The only difference between heat pump and solar pool heater is that pool heater will only work at full capacity when it’s hot out, or else its effectiveness will drastically reduce when it’s cloudy.
The installation of solar water heaters depends on many factors. These factors are solar resource, climate, local building code requirements, and safety issues;
Plumbing and other conventional water heating elements need the same preservations as conventional systems. Glazing is required for cleaning in dry climates where rain doesn’t provide a natural wash.
The basic steps of a solar pool heating system are:
- Install solar collectors on the roof
- Installation of solar water tanks and heat exchangers
- Installation of water pipes
- Install the controls
In some cases, the collectors are mounted on a roof and the piping is run through a wall vertically instead of the roof. Seal all roof penetrations with silicone sealant.
Find the rafters to which you will be attaching the collectors. You may be able to do this with a stud finder, or you can go inside the attic space and make a small hole next to a rafter to locate it. Drill the hole, and then pass a wire out of the hole to help trace it on the outside. Seal the hole with silicone sealant.
Use the manufacturer’s recommendations to seal around the roof pipe Use a water heater sealant to install the roof water heater board to make sure it does not leak.
Test the cold water energy in the house to the inlet of the storage tank, and the outlet of the solar storage tank to the inlet of the conventional water heater. Fit valves and unions on the inlets and outlets of the tanks.
If the heat exchanger is external to the storage tank, a natural convection loop between the heat exchanger and the solar storage tank can be used, or you may fix a pump to force water through the heat exchanger and tank. If you are installing a pump to force the water you can use the inch copper pipe for it.
The controller must have a differential controller installed to sense the temperature difference between the water at the bottom of the solar tank and the top of the solar collector. Attach the censor to the pipe by a hose clamp
The collectors, piping and storage tank should be checked for leaks, the system should be flushed from time to time to remove the tank and collected impurities. The collector’s glass can be rinsed periodically to remove dirt collected in order to improve collector performance.
