First I laid ventilation, then I realized how much money I spent, now I understand where I could save money. I share the details.
Why didn’t I come across self-builders like me, who are ready to go through all the mistakes at their own expense 😀? Everything has to be learned through experience. And the question is always tormenting: why is the truth so simple, lies on the surface, but you notice everything after???
Many will immediately have a question: why is this forced duct ventilation needed at all? And the main reason for installing it in my house will be the presence of a heat exchanger, which I made with my own hands.
Yes, I know, I delayed with his check in the case, but I hope the weather will allow, and one of these days I will get at least some results.
In the meantime, I am finishing the installation of air ducts throughout the house.
And approaching the finale of this work, some moments begin to clear up in my head, which I did not think about at the beginning.
✔ The amount of work seemed small(that there is a small house 8 by 8 meters, with an attic).
But when I sat down to count everything, a normal amount came out. The first, main purchase came out at 20,000 rubles (and these are only pipelines, connections, and fasteners).
Plus, I still had to buy more later.
When everything is almost installed, I understand that it was possible to avoid unnecessary expenses.
All additional, auxiliary elements are always disproportionately expensive (I came across this even when installing the roof, and when I did the wiring of HDPE pipes). And in the case of ventilation, some things can be dispensed with.
For example, fastenings for pipelines. The thing is certainly convenient, but easily replaced by the same perforated tape. And in some places there is no need for fasteners at all.
But most importantly, you need to carefully approach the ventilation scheme.
When the work is almost done, I understand that there is a lot of excess in my system.
I divided the whole house into three groups:
- Two bedrooms.
- Entrance hall, bathroom, toilet, cellar.
- Kitchen-living room (the largest room).
And for some reason, I decided that each group needs a separate supply and exhaust. This of course allows you to make the system separate (ventilate only the necessary rooms), and perhaps the air exchange rate will be better. But is it so critical in such small volumes as mine?
It was possible to make sure that the hoods were in the kitchen, bathroom, toilet. And put the inflow on the bedrooms and living room.
In this case, it would be possible to save decently on ventilation ducts.
But the main results will be at launch.
- How will my recuperator work?
- What will be the air exchange in general, with the fans and ventilation ducts I have chosen?
- And most importantly, will all this bring any benefit to my house at all?
The answers to all these questions will only be in practice, and I hope soon (I try my best).
Friends, I look forward to your opinions and advice in the comments. It's always beneficial.
