Question about room size for heating technology

Hello,

we now have the plan from our architect. The room marked as Hauswirtschaftsraum is quite inconveniently shaped for us.

5.7 sqm (1.50m by 3.80m).

That is a bit too narrow for washing machine and dryer. So we want to use a different room as Hauswirtschaftsraum.

No problem so far.

Now the heating system should be placed in this room.
Dimensions: (TBH) 70cm x 65cm x 182cm (the intake unit is outside)

and the ventilation system.
Dimensions: (TBH) 35cm x 60cm x 65cm

in this room. I have already rounded the numbers a bit.

Does anyone have experience with these devices? Considering that some cables, pipes, and everything else that belongs to it still have to be connected. This is not a shelf that I can just push directly against the wall.

How many cm should I add / do I have to leave from the wall so that it fits?
Is the room sufficient?
How many sqm do the systems take up in total?

Thank you very much.

Hello,

....Now the heating system is supposed to go into this room.
Dimensions: (WxDxH) 70cm x 65cm x 182cm (the intake device is outside)

This will probably be an air heat pump as a split system with an integrated hot water tank in the indoor unit! Is it suitable at all? Heating load, room heating load, heating surfaces, hydraulics?

...How many sqm do the systems take up in total?

I think there is an architect being paid for this!
This seems to be quite a botched system! My condolences!

Best regards

The only thing I know in more detail about the system so far is that there is a 300-liter domestic water tank included. The systems have to warm 170sqm of usable area, with a ceiling height of 2.50m. KfW is around 60 - 65....

As already mentioned, heartfelt condolences!

Regards

Really very helpful and qualified statement.

We planned a somewhat smaller utility room two years ago at the customer's request and had space for a dryer and washing machine; however, nothing more can be accommodated

UPS, well then I'm curious. Mine is also planned that small. According to the plan, a freezer combination also fits in there, and all the doors still open, as I said, according to the plan...

Hello,

Bauexperte do you think that fits? How many square meters do such devices with connections take up? Unfortunately, I have not yet seen such a system fully installed.

I don’t know which system you are talking about – there are combination units ranging from – so I really can’t tell you if it would fit.

The utility room I mentioned measures about 2.70 x 2.47 x 2.60 m, with 3 doors opening from it, so only one completely free wall is available. Along this wall go the main lines, the meter cabinet, and the sub-distribution for the underfloor heating of the ground floor is mounted there. Facing this wall, to the left is first the door to the kitchen and on the remaining section of the wall the washing machine and dryer find their place. Opposite the doorless wall another door leads to the attached garage and to the right of this doorless wall there is enough space for the domestic water tank and the indoor unit of the air-water heat pump, before this wall ends with another door leading to the entrance area.

The only thing I know in more detail about the system so far is that there is a 300-liter domestic water tank included. The systems have to heat 170 sqm of usable floor space with a ceiling height of 2.50 m. KFW is around 60 - 65.

Then it’s high time you get information about the system from the seller/general contractor; you wouldn’t be the first to have to redesign under the trades because the dimensioning of the energy supply was neglected to be discussed.

Kind regards
