Single MVHR Question

[renovator]

Hi All,

 

So I've been reading up on single room MVHR systems for a renovation and extension and have decided the following, but wanted some feedback:

 

1. Current kitchen which will turn into a utility room (3M2):
   1. BSK single room MVHR https://www.bpcventilation.com/bsk-zephyr-single-room-heat-recovery-unit#accordion OR:
   2. Brookvent https://brookvent.co.uk/product/aircycle-one-heat-recovery-ventilation/?attribute_model-type=aircycle+ONE+100mm&gclid=CjwKCAiA9ourBhAVEiwA3L5RFsRvLKJZyJIA4ZR3gmahafMMbTbu96ibDdKDjs1hWNp0IvgjLYA7fhoCmzIQAvD_BwE
2. New open plan lounge (6M x 6.5M): I'm not sure if the flow rate capacity of the BSK can meet the demands for open area lounge, so I was thinking the PRANA 160 Pro:
   1. https://ecostream.org.uk/prana-160-erp-pro/

 

Question for the lounge is can I use one of the cheaper units for the open plan lounge? Also, has anyone come across Brookvent?

 

Thanks for your time.

Anyone have any views?

Wrong the below but never submitted it

 

Look at noise specs before you decide. Some are quite noisy - so be careful with your choice.

One like the Brookvent are used in pairs, so possible use them in the lounge also.

Thanks John - when you mean used in pairs can you elaborate? 

 

Looks like the BSK has IR and Wifi but ever to slightly louder: dba at 3M: (10/18/26) vs (11/19/27)

 

Second question for the lounge / open plan kitchen: Will two of the BSK or Brookvent meet Part F or will one Prana 160 be sufficient? Total area is ~39SQM.

 

Thanks!

Two work in unison, one is sucking the other blowing, for around 20 seconds, then they reverse together and blow and suck. That way the air moves between rooms and a whole space is ventilated. Read the data sheet on the Brookvent ones.

 

When comparing noise levels 3dB is a doubling of noise levels, small number change, big noise increase.
