We will have two full floors plus a sizable attic space above (2.50m (8.2 feet) at the highest point). The attic will be insulated anyway, and the mechanical ventilation system will be installed in the attic.

The gas heater is, of course, nowadays a very compact unit (60x60x180 cm (24x24x71 inches), including a 200-liter (53-gallon) hot water tank), but a pipe will still need to be run upstairs. This could be either natural gas or exhaust gas.

Naturally, one wonders whether it might be better to run non-toxic natural gas through the house (which can only explode at very high concentrations and can definitely be smelled well before that because suppliers add odorants; it is non-toxic) instead of potentially toxic exhaust gas. However, these systems are fundamentally very safe, and a €40 (approximately $43) carbon monoxide detector provides additional security.

Utility room. The technician needs to access it. The chimney sweep for the flue gas measurement. Why place it upstairs without a good reason?

Space saving on the ground floor.
That would be much more important to me than making the annual visit of a tradesperson more convenient. One square meter of living space costs 1800€ (about 1930 USD).

1 m (3.3 ft) of gas piping is more cost-effective and takes up less space than a chimney.

-> Attic, for me, would be no question.

Additionally, the noise is further away from the living area.

Under these circumstances: attic.

We installed the boiler along with a 150 L (40-gallon) hot water tank in the attic, even though we have a basement. The mechanical ventilation system is also located there. You have to duck your head even under the ridge beam.

Sorry, in this profession, you have to expect to kneel or lie down sometimes. As I’ve mentioned before, I’m not going to design my house just to make things as comfortable as possible for the contractor.

The space gained in the basement was used for an additional bathroom for guests.

Water damage would of course be much worse. Our boiler and hot water tank are each placed above a drip tray with a water detector (works like a smoke alarm). This helps, of course, only if someone is at home. Otherwise, you have to rely on insurance. In theory, the trays can also be connected to a drain pipe, but unfortunately, that didn’t work out for us.
