OP (Rob) were you able to wangle a discount code on the NoX kit for a non heated HC model. The wife has given me my orders to get it sorted and stop being a tight bd.

Will do.

(Don’t see any one from vent axia doing this do you?)

Hi Rob

Apologies if I've missed it, but is there any discount available on a heated model with the controls? Also, my neighbour has a log burner that smells a bit when we open our windows, I guess it would also smell from the loft via the vents, would a NoX filter version stop this? If so you can sell me one of those too.....

Although just noted that you appear to be out of stock of the heat and nox version, any idea when you'll be back in stock?

Did you check I-sells on amazon? They have them in stock.

I think all of those items are on the quote. You’ll have to go back a few pages I’m afraid.

Picked up the phone to Rebecca yesterday, ordered the Eco-Heat HC with 4 way switch, arrived this morning. £80 cheaper than the next cheapest place I could find online, so a quick thanks to Rob and to highlight the great service.

Well I've finally fitted mine - it was purchased with the intention of fitting it much earlier but it was a domino situation requiring a few prior steps before I could fit it

I needed to move the Cold water tanks in the loft to create some space

Re do the insulation and flooring in the loft

Move a load of stuff (I don't know why we keep) to site the unit where it would work best

Get the wiring done so it powered by the the upstairs ring main

I had no issues getting the ducting over the outlet or the PIV unit but that might be because I could get it over the heater unit and then clip that to the outlet (when installed in the ceiling)

I am a bit confused by the temperature operation modes so currently I've just set the fan speed to 5 and I'll worry about that aspect later

I'm going to replace the hanging cord with a wire strop because although the unit isn't very heavy I don't trust string

[MrJuice]

Good point

How did you put insulation around the device in the loft?

What is?

I didn't it's suspended 3 feet in the air

I did however cut the loft insulation out where the grill and heater sat between the joists (leaving a small air gap around it but I might do a better job with some PIR

In other news shower room humidity prior to PIV install



Post PIV install



Quicker recovery to pre shower base line without a wide open window to assist

60 is a little bit high. Hopefully over the next few days that will start to get closer to 50.

I've put a humidity/temp monitor in the loft to see what level the air being brought in ranges between

It reached a min humidity of 51% at a temp of 20 deg C at 3pm today (we get a lot of solar gain on the loft due to a large expanse of roof being south facing

It's currently 59% at a temp of 14.9 deg C at 10pm tonight

This morning it was 62% at a temp of 12.4 deg C at 7am

It's never going to be better than the air it's using to source if it did it would be amazing

[Snow and Rocks]

I'm assuming it isn't 12 degrees in your bathroom however?

If you warm up that 62% 12 degree air to 20 degrees it's relative humidity drops below 40%.

Good point - nope it's been a pretty constant 17 deg (except for shower time when it hit 19

According to Mrs BC we are currently in a new "ice age" and we should still be running the heating

Didn't happen today - perhaps I need better "tools" to measure it

[B'stard Child]

Well bugger - unit stopped working, loft temp hit 23 deg - go back and read the destructions

programme 1 means it shuts down above 23 deg (goes into standby mode)

So when I got home power it down and the back on again

Use the two min window to select programme 2

This shuts the unit down over 30 deg C so less likely to go into standby mode during the day when I want the unit to steal heat from the loft (mainly spring and autumn - Summer it’s going to spend a lot of time during the day in standby mode as my loft gets unbearable in the summer)

Next pair the remote controller - got that done

Then I go to select the fan speed and I get nothing

Stuck on fan speed zero

I’m guessing I need to wait till the loft cools down a bit before I can get it running again and select a suitable fan speed

[Gazzab]

My view is that the system isn’t really required in the summer anyway. So if it turns itself off then that’s fine with me.

I can agree with that :-)

In other news loft temp is down to 19.3 and it’s now running again

All that remains to be done is to get the speed right for house size

[remedy]

In the summer, we just get a nice airflow into the house at night.

My measuring device probably isn’t that inaccurate it seems

Loft temp hit 23 deg C and humidity at that point was measured at 41%

[Snow and Rocks]

What makes you think that's wrong? Sounds reasonable to me.

I’m not saying it’s wrong - I’m just surprised it lined up with your calculated (assuption) values

Cheap units from far east

[B'stard Child]

OK Program 1 meant the unit wasn't running for most of the day due to loft temps over 22 deg C

So I tried Program 2

Option	Temp Operating Mode
1	Below 19 "Normal Operation Mode", 18 - 24 "Intelligent Heat Recovery Mode", Above 23 "Standby Mode"
2	Below 19 "Normal Operation Mode", 18 - 31 "Intelligent Heat Recovery Mode", Above 30 "Standby Mode"
3	No Temp Sensing - Constant Normal Operation Mode
4	Below 16 "Normal Operation Mode", 15 - 28 "Heat Recovery Mode", Above 27 "Standby Mode"
5	Not Applicable for Heat Model

This meant de-powering the unit and going through the whole install/Set up procedure (40-50 seconds is a long time to hold buttons for so not totally keen on doing this repeatedly)

The result was same as Program 1 - Unit was off for most of the day and restarted when temps dropped below 22

I wonder if it's the "intelligent" aspect of the heat recovery mode so I'm going to try Program 4 as it doesn't have the "intelligent" aspect according to the destruction manual
