As the greenhouse interior temperature rises above approximately 72°F (22°C), the paraffin expands and pushes the piston outward, which in turn pushes the roof window open. As the temperature drops, the paraffin contracts and the piston retracts, allowing the window to close. Over time, the paraffin can degrade or the piston seals can wear, causing the opener to lose extension force or fail to retract. Replacing the piston restores the original opening performance without replacing the entire opener assembly.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know if I need a replacement piston or a complete opener?\u003c\/strong\u003e\u003cbr\u003eIf the opener housing (the outer cylinder body) and the arm\/quick-release mechanism are physically intact and undamaged, a replacement piston is likely all you need.

It is the best match for the Riga 5, which is designed around a 16\" fan. It also works on Riga 2, 3, and 4 models (though those are typically fitted with a 12\" fan) and on Riga XL series models (though XL units are designed for a 20\" fan — very large XL structures may benefit from two solar kits).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the solar fan work on cloudy days?\u003c\/strong\u003e\u003cbr\u003eIn direct sun the fan runs at full speed. On overcast days output is reduced. Adding two 12V backup batteries (not included) to the included battery case allows the fan to continue operating when solar input is low or at night.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size wall opening does this fan require?\u003c\/strong\u003e\u003cbr\u003eThe fan requires a 16.25\" × 16.25\" square opening, the same as the corded 16\" exhaust fan.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it come with a thermostat?\u003c\/strong\u003e\u003cbr\u003eYes. A thermostat controller is included in the kit and enables automatic on\/off operation based on your set temperature threshold.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need an electrician to install it?\u003c\/strong\u003e\u003cbr\u003eNo. The system runs on 12–26V DC from the solar panel — low-voltage DC that does not require a licensed electrician for installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the motor warranty?\u003c\/strong\u003e\u003cbr\u003eThe brushless motor carries a lifetime guarantee. The kit is manufactured by a factory with a long track record producing exhaust fans for major retailers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does this compare to the corded 16\" exhaust fan?\u003c\/strong\u003e\u003cbr\u003eBoth use a 16\" blade and require the same wall opening. The solar kit adds a 50W panel, thermostat, and battery case for fully off-grid operation, making it ideal for greenhouses without a nearby power outlet. The corded fan ($370) is the lower-cost option when a standard outlet is available.\u003c\/p\u003e","brand":"Exaco","offers":[{"title":"Default Title","offer_id":59770874790174,"sku":"Exaco Solar Ex B","price":849.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/1802\/5246\/files\/solar-exhaust-1.webp?v=1786656855"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/1802\/5246\/collections\/Riga_Roof_Vent_Opener.webp?v=1787346903","url":"https:\/\/rigagreenhousekit.com\/collections\/ventilation.oembed","provider":"Riga Greenhouses","version":"1.0","type":"link"}
