MVHR Design And Install

[Adrock]

Another thread to add to the multitude! 

 

I need a design for my house, I'm happy with installation and construction but I'll need duct sizes and some direction to how I'll get over a couple of tight spots where I have under 90mm from bottom of steel to finished ceiling.

 

I contacted CVC systems over a week ago and the initial emails were very responsive, but nothing at all last week. My situation, which I was very clear about, probably contributed to it. I won't be in a position to purchase or install the MVHR for probably a year or so, but I need the duct installed in the next few weeks.

 

Are on you lovely folk able to point me in the direction of a decent resource to enable progression of the design?

Have you tried BPC Ventilcation? https://bpcventilation.com/

 

Send them your plans, they come back with a design. For a fee I think they then provide you with flow rates etc.

 

I used them for layout design and choice of unit. We had a few back and forth discussions about why certain elements of their layout would not work, but we did arrive at a final design. It was based on using distribution boxes and semi rigid ducting.

I know CVC are crazy busy atm. 
 

Just swap from 92mm round to ‘oval’ (rectangular) duct to pass the steel and then covert back to round. Done it plenty of times.

Some examples of my MVHR installs…

 

 

 

 

 

 

 

 

Hope these examples help. 👍

Cheers @Nickfromwales.

 

I'll chase them tomorrow and if they can't accommodate me I'll get onto BPC and see if they can help. 

 

I'm happy to pay for a design if it helps.

They usually do a design / supply / commission package for self builders who want to DIY, so just ask for a rudimentary layout / design; all you need is the number of ducts and location of terminals, but it’s pretty simple to work out.

 

If you have any long runs to bedrooms, double up on the duct to quieten the airflow as much as possible.

In the process of using Heat Space and Light. Design and supply of parts through them, installation done by the builder or me, and then final commissioning by HSL to get it signed off. Pretty happy with the service so far, at the design finalised stage.

Thanks, I'll look them up. I'm in the process of doing a whole house renovation and I suspect I won't be ready for everything for a very good while. 

 

I might split the the basement and ground floor to get something on the go but that will still be a year in the making.

Its worth getting the design earlier rather than close to when you think you need it, in order to ensure that the various parts will fit where expected. 

 

You may be able to make adjustments to other works to make the MVHR ducting fit better
