Hi, im looking at self installing an MVHR system into my house, it is a 3 bedroom detached house with 1 kitchen and 1 bathroom roughly 130sqm, early next year we will be adding a side extension which will add 1 utility room, 1 bathroom and an office which will take the house to 170sqm. the unit will be placed in  the loft which is boarded out and well insulated and i have a good idea where the ducting can run to be able to reach each room. i am wanting to do the design calculations myself to select the best unit and correct size ducting and looking for a good spreadsheet to start off with, i thought this forum would be the best place to start, thanks

Welcome to the forum.

Sounds like you have researched it well, it’s easy enough to self install. You will need to insulate the unit, ducts & manifolds in the attic.

I can’t help with the calculations but others certainly will.

Welcome to BuildHub.

 

I get the impression that a lot of members don't check the Introduce Yourself forum, and/or stick to sub-forums that interest them. You're therefore going to increase your chances if you ask your question in the MVHR sub-forum: https://forum.buildhub.org.uk/forum/79-mechanical-ventilation-with-heat-recovery-mvhr/

Good luck.
