BEAM AXCO C130 MHRV

Dingodongo · 31-10-2018 10:48pm #1

Have a beam AXCO c130 system installed in my house, just finished. I've been finding the rooms a drafty with the system running. It's set to run at 46% but I usually keep it turned down to 18% on holiday mode to minimise the drafts.

The inlet air also seems cold to me. I was under the impression that the inlet air would be heated to near room temperature.

There are two figures shown on Aurastat controller. One is currently 5° and the other 10°. Pretty sure the 5° is the external temperature so does this mean the 10° is the inlet temperature?

If anyone can shed some light on this or pass on their experience that would be great.

‘Heated to room temp’ - did you buy an integrated heat pump or what is your heating system?

You need to heat your house for the mvhr heat exchanger to work.

I attached my diy temperature monitoring dashboard.

The outside IN temp are very low,at 9.9
The inside IN temp are the highest ones at 18.7 ,as they collects the warm air from within the house,from various rooms and temperatures.
It mixes the cold fresh from OUT with warm dirty from IN and send it dirty outside at 11.5.
The resulted mixed warmed fresh air is pushed down the internal ducting system,back in to your rooms at 17.6

I have one inlet fitted in the hot press room,where the warm equipment is installed...that takes the warmer air from the house and warm-up the cold outside.
Normal you should have one inlet in each room.

Each of my feeding fresh warm air from the rooms have one temperature monitor off ebay,like one below.
Thats just to confirm the temp and humidity.
Im working in getting one centralised but no time left for this challenge.

Based on above, can we figure out what's the issue with your system !?
I guess is the IN fresh at 5" and OUT dirty at 10" !?

OP - check your summer bypass settings.

Is all the ducting insulated or at least within the insulation envelope?

It’s worth remembering that firstly heat recovery ventilation will have some heat losses so the incoming air will never be the same temp as the outgoing air. Also moving air will always feel cooler than still air.

BryanF's questions are right - those internal temps seem quite low. How are you heating the space? Is the heating source operational?

I also have the same system in my house. I'm a bit concerned that some rooms in the house are not as 'fresh' as they should be namely my bedroom with adjacent en suite. I often wake up to condensation on the bedroom windows. In the past I attributed it to having a shower the night before and there being moisture in the air. However the en suite outlet should be capable of taking this moisture out of the bathroom. I've even used the 'boost' put to increase the outlet capacity for a short period of time. Is there any device like the temperature monitor in the picture above that would give me an accurate recording of the air quality in the room.

I've called the installer on this before and wasn't exactly happy with his response to the issue. As I've no stats on the air quality it's hard to pin them down on the systems performance. However if I had Data to inform me of the air quality there would be know ambiguity as to the performance of the BEAM system .

Distinct possibility that yours is not balanced right. You need specialist equipment to confirm that.

You could also just get a cheap humidity sensor but ultimately you need to check the balancing. You certainly shoud not have condensation on the windows the following morning.

Just looking to replace my filters, which direction should the arrows for airflow be pointing? Towards the unit or away?

Where are you getting your filters for the c130?

53€ from beams when ya add vat and delivery is steep

I'm in the same boat. I found a website called filteria24 dot com but it doesn't look professional and gave an error when I tried to checkout using PayPal.

In the end I ordered replacement filters for my C130 from "The Filter Business" in the UK. There are two filters required for the C130, here's what I was quoted (incl. VAT) from them in Feb 2020 to replace the two G4 filters that originally came with my unit.

£7.51 - G4 Pleated Panel (405h x 230w x 25d)
£7.51 - G4 Pleated Panel (335h x 230w x 25d)
£18.00 - Next Day Delivery to the UK only (up to 15kg)

Delivery to the UK only wasn't a big deal, I have an AddressPal UK address, collection from my local post office is then an additional €4. But £18 delivery on a £15 order is hard to take. So I ordered 3 sets of filters (6 filters in total) and the delivery charge was the same. I also upgraded from G4 to F7 for the outside air filter.

£22.13 - F7 Pleated Panel (405h x 230w x 25d) x 3 = £66.39
£7.51 - G4 Pleated Panel (335h x 230w x 25d) x 3 = £22.54
£18.00 - Next Day Delivery to the UK only

Total = £106.92

That ended up being €128.94, plus €3.95 for AddressPal delivery, so say €133 for 3 sets of filters, €44 per set delivered. Better than the €53 per set from Beam. If I hadn't upgraded to the F7 filter it would have ended up at under €27 per set delivered, which is half the price from Beam.

So if you're willing to stump up more to lower the per-unit cost of delivery, it's well worth it.

Hope this helps.

How did you resolve this problem As I have the same issue
