Vent Axia Lo-Carbon Tempra P Heat Recovery Unit (443312)
-
DETAILS
Constant trickle speed with pullcord to boost or intermittent operation by pullcord.
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).
Range Product Specification
Complies with Building Regulations Part L 2010:
Low energy consumption means the Tempra exceeds the energy-saving requirements in Part L, Conservation of Fuel and Power.Versatile control:
Switching on/off or from a trickle to boost speeds is possible in several ways: Switched Live, Pullcord or Humidistat. Overrun and delay start timers are also available.Summer 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.Fits 100mm diameter hole:
The Tempra will fit 100mm through the wall applications as a straight replacement for a traditional extract fan.Continuous or intermittent flow rates:
Air flows can be set to quiet, low-speed continuous rates or high-speed intermittent boost rates.Low energy consumption, low noise:
The unique twin impeller design consumes as little as 2.0 Watts and operates almost silently on trickle setting.Long Life ECDC Motor:
The units are fitted with a 24V ECDC motor with a state of the art built-in power supply. This has the ability to operate at only 2 Watts power consumption on normal setting, offering a 90% energy saving over conventional AC equivalentsMaintenance:
Apart from removing odours, providing fresh air and recovering heat, this appliance extracts airborne impurities such as dust, dirt and grease. These gradually build up and detract from the efficiency and appearance of the appliance. To ensure peak performance, the heat exchanger should be cleaned as required in accordance with the instructions supplied.Typical Installation:
The 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.Easy installation and maintenance
With simple construction, Tempra is both easy to fit in the same location as an existing 100mm diameter fan, and with easy access to the heat exchanger for maintenance.

Great price, delivered fast and not too hard to fit - be sure to fit a 100mm pipe for it to slide through - this makes installation much easier. Full power is quite loud but the standard low power is acceptable. Not sure you would sleep that easily with it running - hence the four stars, I had hoped it would be quieter. On a cold day the incoming air is noticeably warmer than the outside air temperature. -

Does exactly what it says on the tin. Little noisier than i expected but does the job.Many thanks i-sells. -

Fan is clearly audible at low speed & is quite noisy at boost - I'm glad I have a manual pull cord to keep it at low speed unless the shower is/has just been on. I wouldn't put this in an en-suite because it might still be audible at low speed even with the door shut. It does keep steam levels down when showering and on boost speed. Note that even with the heat recovery - the incoming air feels cold - I've yet to take actual temperature readings though.

Replied by i-sells, 03-03-2016#5InstallationIs this suitable for a ducted application, duct length approx 2 m.
Question by Eamonn Nolan, 17-08-2016Hello Eamonn
Looking at the data sheet it states the unit is suitable for walls 385mm thick. There is no extension kit available and this indicates it may not be suitable.This doesn't mean it can't be done but the likelihood is that the efficiency will be compromised.The Kair K-HRV150 can be extended up to 1 metre and does have an extension kit option however longer than that and air movement is compromised.Depending on the installation limitations either the range of in-line fans or Centrifugal extract systems (some very low energy) such as the Vent Axia Solo range Quick Search QS3284 would be suitable for long duct runsReplied by i-sells, 18-08-2016#6Fan fittingHi My wall is only 250mm thick, is it ok to have the flue sticking out By how much? Does it come with manual control switch for speed?
Question by Ted Lee, 21-03-2017The minimum length of the duct is 320mm so there would be an extra 70mm of exposed duct in a 250mm wall. The fan is a pull cord version so does not require any other control.
Replied by i-sells, 21-03-2017#7Fitting locationHi Can this be fitted directly above bath, shower. If not how far away it needs to be? Thanks
Question by Ted, 21-03-2017This system should not be located in zone 1 above or in the shower or above the bath, for that you should look at the Lo-carbon Tempra SELV versions
Replied by i-sells, 21-03-2017#8fittingHi can this unit be fitted in the basement ? Dose this unit circulates the air? Thank you
Question by sazid, 29-06-2017Hello Sazid
The unit is a heat recovery ventilator that is continuous running and both extracts and supplies air, therefore it also creates air movement. It is classified as a single room system so should be fine for a basement.Replied by i-sells, 03-07-2017#9BedroomWould this product be good for a small bedroom with bad condensation ?
Question by Peter McGuinness, 03-02-2021Hello Peter
Thank you for your question. This model is not designed to be installed in a bedroom. Our HRV150 is as it has a night sensor so the unit will not boost when you are sleeping. Unfortunately we do not have this item in stock until the 12th April but you can place an order to be put on back order and as soon as they come in you will be allocated one. To have a look at the product the code is QS2838. If I can help any further please do not hesitate to contact meKind RegardsAnitaReplied by i-sells, 03-02-2021#10Part DefectDear Sir or Madam, This is in reference to: https://www.amazon.co.uk/gp/product/B00274THNI/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 I bought this product on Amazon and after installing it, we noticed that the shutter is not opening or closing. The electrician said the little brown piece that pushes the mechanics for opening it is not working. We would like to get that replacement only, rather than replacing the whole unit, which will also cost the electrician to install it again. Where can I find the piece? I wanted to send a picture, but I do not think it is possible in this format. Please contact me via Email so that I can send you the picture. Thank you Kind Regards Gemma
Question by gemma fernandez, 03-02-2021Good morning. If you send an email to hello@i-sells.co.uk it will be picked up by the relevant department.
Replied by i-sells, 04-02-2021#11extensionIs it possible to extend this item? The maximum length seems to be 46cm. Due to the position of a stud in my basement I need it to be 125cm in straight length, is this possible?
