ᐅ Energy Saving Regulations with Gas Boiler and Heat Recovery Ventilation Instead of Solar?

Is it not recommended for cost reasons? I mean, solar thermal is only for water heating – and I’ve read that an average person uses about 1000 liters (260 gallons) of water per year – is it worth it?

Subjective opinion: Solar thermal for domestic hot water is only useful in special cases (pool or similar). Currently, at an outdoor temperature of 5°C (41°F), I need about 2 to 3 kWh for hot water (air-to-water heat pump) per day (which costs about 40 to 60 cents). In my opinion, this is something solar thermal can never really make up for...

I didn’t want to start a new thread since my question is quite similar.
Our plots will be allocated in Q1, and we have already been thinking about the floor plan and so on. In terms of interior fittings, +1 and I have very similar ideas so far; the only open topic is still the heating system.
You hear 20 opinions from 10 people, but so far, what we liked most from acquaintances (new build from 2013) was a gas boiler with controlled ventilation and heat recovery. A friend is currently planning their build with an architect (supposed to meet the 2016 energy saving regulations), and they were told that gas plus controlled ventilation with heat recovery is not sufficient for the 2016 energy saving regulations. Is this information reliable, or is it outdated knowledge?

That is possible.
For the thermal insulation certificate, you will need an energy consultant anyway. Discuss this with them (and make sure to hire one who does this as their main profession).

It is definitely possible and is standard practice with our general contractor.
