The Vent-Axia Lo-Carbon Tempra is available with pullcord control, timer control or humidistat, timer and pullcord. All models are also available in SELV (Safety Extra Low Voltage).\u003cbr\u003e\u003cbr\u003eTypical Installation: \u003cbr\u003eThe Lo-Carbon Tempra unit is designed for installation in a 102mm (4) core drilled hole. All installation can be carried out from inside the building. The units are suitable for external walls up to 318mm thick.\u003cbr\u003e\u003cbr\u003eLegislation Compliance:\u003cbr\u003eThe Lo-Carbon Tempra complies with the air flow requirements of the new Building Regulations Part F 2010 and with the energy consumption requirements of Part L 2010. For best practice, Part F requirements apply to both new build and refurbishment installations. Part F 2010 There are three means of mechanical ventilation specified in the Building Regulations: System 1, Intermittent Extract Fans, System 3, Continuous Mechanical Extract (MEV) and System 4, Continuous Mechanical Supply and Extract with Heat Recovery (MVHR). System 1. Instead of using a traditional intermittent extract fan, the Tempra, running on continuous setting may be used. This method has the advantage of reducing the overall background ventilation requirement by 2500mm sq. and removing the need for background ventilation in the room in which the unit is sited. System 3. Using Tempra in conjunction with MEV\/dMEV permits a reduction in the overall dwelling extract rate. This is particularly useful for extensions, loft conversions and refurbishments which might otherwise be difficult to ventilate. Part L 2010   Building Regulations Part L1A and L1B 2010, Conservation of Fuel and Power refer to the energy performance requirements set out in the Building Services Compliance Guide. Tempra falls comfortably within the specific fan power (SFP) requirement of 1.5 Watts per litre per second (W\/l\/s) for MVHR.","brand":"Vent Axia","offers":[{"title":"Default Title","offer_id":58031898394888,"sku":"VEN 443310","price":274.65,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1044\/2362\/0872\/files\/vent-axia-443310-lo-carbon-tempra-t-heat-recovery-unit-timer-1139-p.jpg?v=1784040862"},{"product_id":"vent-axia-443311-lo-carbon-tempra-htp-heat-recovery-unit-humidistat-timer-pullcord","title":"Vent Axia 443311 Lo-Carbon Tempra HTP Heat Recovery Unit Humidistat, Timer, Pullcord","description":"\u003cstrong\u003eVENT AXIA 443311\u003c\/strong\u003e\u003cbr\u003eVENT AXIA TEMPRA HTP HEAT RECOVERY UNIT\u003cbr\u003eSingle Room Constant Trickle Heat Recovery Unit with Humidistat and Timer\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePerformance:\u003c\/strong\u003e\u003cbr\u003eTrickle Low 6 L\/s \/ 21.6m3\/hr\u003cbr\u003eTrickle High 9 L\/s \/ 32.4m3\/hr\u003cbr\u003eBoost 15L\/s \/ 54m3\/hr\u003cbr\u003e\u003cbr\u003eRequires the following additonal part available at Extractor Fan World:\u003cbr\u003e445529 Wall Sleeve\u003cbr\u003e\u003cbr\u003eHeat recovery is the collection and re-use of heat from extracted air that would otherwise be lost.

Overrun and delay start timers are also available.\u003cbr\u003eSummer Setting: The extract-only Summer Setting helps keep you cool by closing off the intake from outside, reducing the amount of warm air entering the dwelling.\u003cbr\u003e\u003cbr\u003eRange Overview:\u003cbr\u003eRevolutionary patented technology; The Vent-Axia Lo-Carbon Tempra through the wall heat recovery units are suitable for fitting through a 102mm (4) circular hole and are designed for use in bathrooms, toilets and utility areas. Under the new Building Regulations Document F continuous running products, such as the Lo-Carbon Tempra only need to move the amount of air as laid down in table 5.1a of Document F. The Vent-Axia Lo-Carbon Tempra is available with pullcord control, timer control or humidistat, timer and pullcord. All models are also available in SELV (Safety Extra Low Voltage).\u003cbr\u003e\u003cbr\u003eTypical Installation: \u003cbr\u003eThe Lo-Carbon Tempra unit is designed for installation in a 102mm (4) core drilled hole. All installation can be carried out from inside the building. The units are suitable for external walls up to 318mm thick.\u003cbr\u003e\u003cbr\u003eLegislation Compliance:\u003cbr\u003eThe Lo-Carbon Tempra complies with the air flow requirements of the new Building Regulations Part F 2010 and with the energy consumption requirements of Part L 2010. For best practice, Part F requirements apply to both new build and refurbishment installations. Part F 2010 There are three means of mechanical ventilation specified in the Building Regulations: System 1, Intermittent Extract Fans, System 3, Continuous Mechanical Extract (MEV) and System 4, Continuous Mechanical Supply and Extract with Heat Recovery (MVHR). System 1. Instead of using a traditional intermittent extract fan, the Tempra, running on continuous setting may be used. This method has the advantage of reducing the overall background ventilation requirement by 2500mm sq. and removing the need for background ventilation in the room in which the unit is sited. System 3. Using Tempra in conjunction with MEV\/dMEV permits a reduction in the overall dwelling extract rate. This is particularly useful for extensions, loft conversions and refurbishments which might otherwise be difficult to ventilate. Part L 2010   Building Regulations Part L1A and L1B 2010, Conservation of Fuel and Power refer to the energy performance requirements set out in the Building Services Compliance Guide. Tempra falls comfortably within the specific fan power (SFP) requirement of 1.5 Watts per litre per second (W\/l\/s) for MVHR.","brand":"Vent Axia","offers":[{"title":"Default Title","offer_id":58032186032392,"sku":"VEN 403834","price":295.89,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1044\/2362\/0872\/files\/vent-axia-403834-lo-carbon-tempra-lt-heat-recovery-unit-timer-long-heat-exchanger-3898-p.jpg?v=1784041948"},{"product_id":"vent-axia-403836-lo-carbon-tempra-lhtp-heat-recovery-unit-humidistat-timer-pullcord-long","title":"Vent Axia 403836 Lo-Carbon Tempra LHTP Heat Recovery Unit Humidistat, Timer, Pullcord Long","description":"\u003cstrong\u003eVENT AXIA 403836 Tempra\u003c\/strong\u003e\u003cbr\u003eSingle Room Constant Trickle Heat Recovery Unit with Humidistat, Timer, Pullcord and extra long heat exchange unit for thicker walls.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePerformance:\u003c\/strong\u003e\u003cbr\u003eTrickle Low 6 L\/s \/ 21.6m3\/hr\u003cbr\u003eTrickle High 9 L\/s \/ 32.4m3\/hr\u003cbr\u003eBoost 15L\/s \/ 54m3\/hr\u003cbr\u003e\u003cbr\u003eHeat recovery is the collection and re-use of heat from extracted air that would otherwise be lost.

This air passes through a filter to ensure that clean air enters the room. These systems work best in pairs as when one unit is extracting, the other can be supplying air to provide a balanced ventilation system.
