Hello dear builders,

my better half is currently drawing our new "dream house" in CAD. She planned a very large (approx. 13 sqm) utility room to fit everything in and still use this room as a passage to the carport or cloakroom (rubber boots, etc.) for our little son. I had the idea to install the entire system in the attic, since with a pitch of about 40 degrees, the attic only has a height of about 1.83 meters in the middle, so it won’t be usable as living space and is mainly intended for storing boxes. I assume we will build a KFW 55, but at least 70.

For this reason, attached is the question of the advantages/disadvantages of heating and hot water storage in the attic?

Best regards

Bernd

Hello Bernd,


But you do know that you need an architect, right?


This room is big enough to also accommodate the technology.


KfW 70 is a reasonable calculation size; KfW 55 depends on the material used for the outer wall/masonry and is a cost matter in the range of up to an additional EUR 25,000.

The disadvantage of this positioning of the technology is that you have to spend more money; the utility company always installs up to behind the first wall. This means you have a longer pipe run. Another aspect you have to consider is that a tray must be placed under the domestic hot water tank in case the container becomes porous at some point, and generally no concrete ceiling is poured above the attic. And finally a personal decision: "is it okay with me that during maintenance work the technician walks through my house."

Kind regards

One can also have a different opinion. KfW 70 and 55 differ not only in Ht but also in the Qp’’ value. Sometimes, with very little extra effort, a single-family house 70 can be represented as a single-family house 55. On the other hand, a single-family house 55 that looks good on "paper" can turn out to be just an energy saving ordinance standard in practical reality!

Best regards.
