ᐅ Can you place a hot water storage tank directly on the screed?

Hello,

We are currently building a semi-detached house and are deciding whether to have the technical room of about 18m² (190 sq ft) tiled by the developer at €15/m² (€1.40 per sq ft) for €1,400, or to do it ourselves afterwards.

The problem is, if we don’t order the tiles, they will place the 150-liter (40-gallon) hot water tank directly on the screed floor. Is this a problem? Can the hot water tank simply be placed on the screed?

As far as I know, it should be placed on a platform (which they won’t provide), so either on the screed or on tiles (if ordered).

What do you think?

1400€/18 sqm (193.8 sq ft) = 77.8€/sqm (7.2$/sq ft) with a material cost of 15€/sqm (1.4$/sq ft) (plus adhesive). Nice hourly rate, but that's probably how it is with very small quantities.

I would skip that. I don't see any disadvantages, except that water tanks are usually round, which means more cutting afterwards.

It’s also on top of our screed, since it’s a basement :-D only the basement hallway is plastered and tiled

In our case, it is placed in a basin with a drain in case it leaks.

The problem is that if we do not order the tiles now, they will place the 150L (40 US gallons) hot water tank directly on the screed floor.

As far as I know, it should be on a pedestal (which they won’t do)—so either on the screed or on tiles (if ordered).

If you do it yourself, you can also do it in stages.
Our process was: pour the screed, wait 14 days, install tiles where the heating unit will be, have the heating installed, heat up the screed, then install the remaining tiles in the utility room once the screed was dry enough.
