ᐅ Planning a Central Vacuum System

Hello,

We are currently undertaking a full renovation of our house. Since we are adding an additional floor, we also want to install a central vacuum system... but which one?

Here are the key details:
The ground floor is about 100m² (1076 sq ft), the new upper floor around 60m² (646 sq ft) (1st floor),
the longest distance on the ground floor is 11.20m (36.7 ft), and upstairs 7.10m (23.3 ft).
The central unit can be placed in the basement but it doesn’t have to be, as the garage is about 4m (13.1 ft) away from the house, so a pipe could also be routed into the basement.

My idea was to install 2 vacuum inlets on the ground floor plus a cleaning hatch at the base of the kitchen cabinets, on the 1st floor just one in the hallway, and possibly one in the garage as well for vacuuming the cars.

Of course, I’ve already read quite a bit here and found a lot on the internet, but every house and its occupants have their own specific needs. I will install the system myself as I do almost all other work on the house.

What I want to know is...

Which manufacturers are recommended?
How powerful (in air watts) should the vacuum be?
Do the pipes have to be from the system manufacturer, or would 50mm (2 inch) HT (drain) piping with double seals work as well?
etc.

The budget is around 5000€ (about 5000€), but there is some flexibility.

If you need more information like plans, I’m happy to share them.

Best regards, Markus

But isn’t that also the case with vacuum cleaners that have a HEPA filter? I also find it strange: you build your house as airtight as possible, and then you blow the warm air out through such a device...

And how many of the new airtight houses operate without controlled mechanical ventilation and just blow the warm air out the “window”? The warmer air is already at the top; near the vacuum cleaner head, it’s actually cooler.

We have a vacuum cleaner with a HEPA filter, which we bought shortly before building our house last year because the old one was broken. Unfortunately, it was an expensive, good model, and at that time the idea of a central vacuum system wasn’t even known yet—it only came up later during the planning. But it wasn’t really impressive, especially since my wife has a typical house dust allergy; we noticed the exact difference, and the central vacuum system clearly has the edge.

@Manu: By the way, my wife also wanted a regular vacuum cleaner again. She still has the relatively new one we had stored at my parents’ place, intending to use it for the car, etc. Then we brought it back home, but she didn’t really like it compared to the central vacuum system. I think you need to have both and be able to use them separately to know which you prefer.

We vacuum daily or even twice a day because of pets and children. I always vacuum in the evening since I manage better with the longer hose thrown over my shoulder, rather than my small wife carrying it upstairs. Also, she’s a bit lazy and doesn’t like vacuuming under the couch :-P The central vacuum system takes up about as much space as a good large upright vacuum, like a Vorwerk (brand referenced only as comparison). We collapse the telescopic tube together, toss the hose over the holder three times, and the hose is kept slim at 35cm (14 inches) width with side holders, so the full 8 meters (26 feet) uncoil quickly. If it ends up “messy” in the living room, it’s more the user’s fault than the vacuum’s.

For us, the regular vacuum was often left standing or lying around in the hallway or bedroom because no one wanted to carry the thing back down the stairs and put it in the storage closet, where the vacuum pipe would slip away or fall over. But you have to learn to handle the long hose properly, that’s true. It was probably easier for me because I was used to handling hoses over my shoulder from my work with the fire department.

Personally, I find stairs more awkward with a regular vacuum cleaner—carrying it in one hand upstairs while vacuuming with the other, managing a trailing power cord, etc.—but everyone probably has different pros and cons.

We don’t have a central vacuum system.

Because of the dog hair on the stairs, we bought a Dyson cordless vacuum, the Animal Pro model. By now, the big upright vacuum cleaner is hardly used anymore. At some point, strangely, there was also one of those Dyson units mounted on the wall on the second floor. You basically keep it handy like a broom.

Sorry for going off topic. But I had to smile about our “decentralized alternative.”

Hello!
I have had a central vacuum system for several months now, and I would never want to give it up!
I suffer from a house dust allergy myself, and since installing it, I feel almost cured.
The dust is collected directly into a container, which in my case is located in the basement. With regular vacuum cleaners, dust and dirt are only filtered and then blown back into the room. That means the fine dust particles return to the indoor air, which is why my allergy never improved before!

Regarding noise, I can only say positive things! The sound is minimal, and I can even have a phone call while using it!
I also can’t imagine using a conventional vacuum cleaner for cleaning my car anymore. With this hose, I am completely flexible, no more dragging around a heavy machine.
So, I can fully recommend a central vacuum system!
I got my system from STREAMVAC.
