ᐅ Is it possible to have gas heating without solar panels in a new build?

We are currently planning our new build and struggling with the heating system. The living area of the house is about 165 m² (1776 ft²) plus a heated basement that is rarely used. The house features KfW40-level insulation, controlled mechanical ventilation, and underfloor heating.
Originally, we wanted to install a heat pump, but the prices for heat pumps are outrageous. Even with rising gas prices (electricity prices have also increased), we wouldn’t be able to recoup the initial investment (the additional cost for an air heat pump compared to gas from various builders is around €15,000-20,000). Therefore, we are planning to go with gas heating, with the option to switch to a heat pump later on.
The KfW40 subsidy is no longer available, and I am wondering if it is possible to install a gas condensing boiler without solar thermal panels under the building energy law, given that we already have good insulation and controlled mechanical ventilation. The idea is to save costs and leave more room for photovoltaic panels in the future. Does anyone have experience with this?

Warning, off-topic…
Don’t overestimate the business idea: this thing doesn’t compete with a caravan, as it is far too large, heavy, and expensive. Those who can afford it probably already have a proper boat at their dock, own a lakefront property, or need to spend their money in some other way. Investors are more likely to rent it out than to move it around themselves.
August 27… the date conflicts with the Caravan Salon in Düsseldorf 😳 Unfortunately, it’s no longer an option for us after my husband checked the current price earlier. It was less than half that amount 3-4 years ago and only a few euros more expensive than a good caravan.

Update: It’s no longer relevant. :-( My husband told me earlier that the price of around 99,000/100,000 € from about 3-4 years ago has now increased to 200,180 €. :-( Demand seems to be high; otherwise, such price increases would presumably not be possible. I have read a current starting price of 99,000 €. Even that is far too expensive for leisure and vacation enjoyment just 6 weeks per year.

The better the insulation of the house, the more significant these factors become. Cooking, TVs, people, tea lights... all of these are internal heat gains that the heating system doesn’t need to provide.This really shouldn’t be underestimated. I would never have imagined it in our old rental house, but in a new build, it’s quite intense.
We only have KFW55 standard, but by May you already need to think about shading; otherwise, after a few days, the air conditioning kicks in.
When guests visit -> set the ventilation to party mode or really cross-ventilate, because just 2 additional adults in the living room cause a lot of heat buildup after a few hours. I don’t even bother lighting tea lights anymore. 😀
Hello,

I just took a look at it. It’s basically a fairly standard houseboat with an appropriate trailer. The price is exorbitant, but boat prices are simply absurdly high. You can’t compare it to a €30,000 caravan, even if at first glance it seems to offer more space.
The problem: this thing can’t be towed by a regular car, as it apparently already weighs 3200 kg (7,055 lbs) empty. At least the XL version. So with the trailer and equipment, it’s over 4000 kg (8,818 lbs)!
You’d need to buy a 7.5-ton (16,535 lbs) truck as a towing vehicle… ;-)
The fact that they don’t provide dimensions and weights would always make me suspicious when it comes to boats and trailers!
Best regards,
Andreas

With a one-day course and B96, medium-sized caravans are usually allowed.
