Do you have an annual consumption value?

Unfortunately not, we didn't get any from the previous owner..
I have calculated that we currently consume about 110m³ of gas per day. I should also mention that my wife is still at home at the moment because of the baby. She will go back to work in April.

You must have received an energy certificate.

110m according to the gas meter?

You need to tackle this immediately, your system is just dumping the gas straight into the chimney. In other words, this is already life-threatening.

That already sounds adventurous... without underfloor heating, gas will probably be the only sensible option.

Maybe have a calculation done to see where the air-to-water heat pump + new low-temperature radiators - subsidy stands. But it's best to have the air-to-water heat pump offered by another company.

Yes, according to the gas meter. There are no values available on the certificate (i.e. consumption values) The energy certificate states:
    [*]Final energy demand: 201.7 kWh / (m²*a) [*]Primary energy demand: 234.1 kWh / (m²*a) [*]CO2 emissions: 56 kg / (m²*a)
We are working on it!
