MVHR, 9 Supply, 6 Exhaust connections

I hope i can balance the flow rates once i get to that stage but i have a different number of inlet & exhaust ports.  I guess the flow is the important parameter here.

Pretty normal to a mismatch in supply and extract count.

 

The important bit is the correct supply or extract, whichever the greater, then match both supply and extract flow rates.

Yup. Never had one in stall where these ‘match’ tbh. The balance is achieved via commissioning and setting of flow rates according to spaces and what-not.

 

Relax, once installed and you’ve a year under your belt you’ll see how inconsequential these things are vs the cost of beer etc  

 

MVHR requires very little science in actuality, but one thing I can promise you is that once you’ve had a home with good air tightness & MVHR I doubt you’d ever go back to living in a home without it.

I was ready to hit the 'buy now' button this morning on a unit from a company called Intovent in the Netherlands.  I thought i would check first. They cannot deliver to the U.K. 

Which is a great pity because the price is amazing. 2267 Euro.  Less than £2k
