Is there an inexpensive MVHR diy option?

[Post and beam]

What i saw at the show when i looked inside their unit.  Cheap looking bent tin and electronics that looked like a 4th form GCSE project using an Arduino. Untidy & cheap looking. 

Their summer by-pass was an extra cost add on, dont like that.

Rega vents design was a branched  idea as well which i expressly did not want.

Care to expand why?

 

I was also quoted a similar amount for a REGA unit - £5k for supply only, £7k for supply and install. Chose to go with Zehnder based on recommendations (which has turned out to be much more expensive sadly!) but I'd like to understand why REGA are considered so bad.

I could show some pics of installs, ducting like tumble drier hose, held up (strangled) with cable ties, and other such very 1st year apprentice stuff. Looked like fed up teenagers fitted it as part of community service. 

 

Just worse than bread & butter stuff, and failures of whole house systems which needed total gut out by replacement suppliers and installers.

 

As said, avoid. Or don’t.

@Wadrian . I did it. That's all you need to know for how easy it was. I think from memory and some years ago unit and pipework maybe 3k ish.

Think I had read £10k on earlier post on Buildhub. Would be good to know if this is wrong 

10K is correct. That's what I charge.

He actually only charges £9k, the rest is my manager's fees.
