Vent Axia Lo-Carbon - Intro
For the most part the instructions give a good of idea how to install this thing. But the template that comes with the heat recovery fan is pants.
Vent Axia Lo-Carbon - Install Guide
There is one inadequacy with the instructions provided. That is the cable entry point, and also no description of how long the cable should be.
1 - The Cable Needs to be Long
The cable entry point (centre left of template) is around 15 - 20cm away from where you need to connect the cable internally (top left of unit). After leaving 10cm of cable sticking out of the wall, I was left short. Despite the requirement for a long cable there is very little room behind the unit for connectors etc. which makes adapting cable length with clamp type connector difficult.
2 - Cable "Threading"
You also have to thread the cable through the body of the extractor fan. This would be relatively hard to do with 2.5mm cable. Bit probably OK with 1.5mm or flexible.
3 - Template
There is nothing wrong with needing a long wire, but wire not mention this on the template!
4 - Run Off a Socket?
Yes you can run this off a socket. Handy if you want on and off to be timed.
Vent Axia Lo-Carbon - Review
It seems to work OK, in terms of heat recovery. It is a bit noisy however. I used to ventilate my garden office with a couple of 120mm fans from a PC, which was better in terms of noise.
If I went again I would likley buy a passive MHRV unit for £99, some ducting and use PC fans again.
This vent axia lo carbon does have a boost function which shifts a lot of air, and also a summer bypass flap, so you can set it to just extract in the summer.
Its a good bit of kit . . . . just a little too noisey.
All the best,
Obviously this system could burn your house down if connected up incorrectly, and any cutting of wires will void any warranties. Do all of the above at your own risk. After all I have just written about what I am doing, it is your choice if you decide to do any of the above.
