- Oliver: If you current discussion around the building of modernization law, you might think gas heating could celebrate But it's not easy. Because even if the planned GMG to install new gas and oil heating, the decisive question what does it over the next 20 years and is it And this is it exciting. Because many owners look at the purchase cost Of course, gas heating is often cheaper in the purchase than, for example, heat pump for funding. actual costs are not created when buying, but in running operation, over a period of 10, 15 and 20 years, for which they are designed The planned building modernization law suggests that fossil fuels should step by step with renewable energy carriers. The model is often called the bio staircase. Specifically, this Earth gas is to with biomethane or hydrogen. Biomethane is bit likely than hydrogen, but that's a completely different topic. The goal is to CO2 emissions with these technologies. The problem is that the energy carriers are relatively short and in the end much more expensive than conventional earth gas. Current calculations from CO2 Online show that the heating costs can be significantly increased. Over a period of 20 years, a classic earth gas heating costs around 55,500 euros. If biomethane or hydrogen are the total costs even to over 65,000 euros. For comparison, a heat pump has running operating costs of 22,000 euros, air-water heat pumps of 24,500 euros, wood pellets that are then at 32,500 euros, remote heating, which is still relevant is around 46.000€. Earth gas is around 55.500€. And really expensive is earth gas with biomethane, earth gas with hydrogen and heating oil. All of around 65.000€ to 67.000€. The differences are really huge. A water-fuel pump causes, according to this prognosis, 20 years, more than 30.000€ less heating costs than a gas heating. In contrast to an oil heating, is even 40.000€. Why is that? The decisive advantage of the heat pump is the efficiency. From a kilowatt hour of it average of 4 kilowatt hours of heat. This is the so-called annual labor number and thus it significantly less energy than conventional fuel heating. At the time, electricity from the expansion of renewable energies Fossil energy carriers remain dependent on international markets and are additionally burdened rising CO2 costs. And they not even so exogenous shocks like the Iran war or something like that. Of course, this does not that every property is automatically for a heat pump. There are buildings where the heat is more useful. There are also cases where individual renovation measures are necessary, especially to the heat load and then a heat pump efficiently. There may even be existing buildings that with hybrid solutions. But one thing shows this development very clearly. The question today is no longer heating is the cheapest The crucial question is which solution over the next 20 years. And that's why we just at investment costs, but always the overall picture of the means of cost of energy consumption and long-term economy. And if you assessment of how gas heaters can meaningful way, then the number is really close to zero. Because in the end, price of heating over the economy but the sum. at costs over the entire life span.
