HEAT ST – Autarcic heating

03/06/2024

Summer Term 2023 / HEATST

EXECUTIVE SUMMARY

We, Dominik Kern, Florentina Steindl, Jona Kislinger, Stefanie Bauer and Laurenz Roth, are HEATST. With our Project that has arisen from the Garage, we want to be part of the energy transformation to a sustainable and autarkic future.

Goal

Our vision is to create a heating system which is completely CO2 emission free, based on local available resources and provides safe, reliable heating. Because people deserve a climate friendly future but also not to worry about where their energy comes from and being independent from suppliers. Today we’re in the middle of the climate crisis and we need a transition to sustainable and renewable sources as fast as possible. That’s why we want to be part of this transition with our heating system. The effects of the climate crisis have already arrived in Europe, noticeable by ever-increasing temperatures and natural disasters. This is demonstrating to us that the time available is running out. In 2023 Russia's war of aggression against Ukraine showed us the effects of a gas dependency. This has directly affected the Austrian citizens which is why the attention of politics rose. In November 2022 in the “Erneuerbaren-Wärme-Gesetz'' was presented, with the plan that from 2023 onwards it will be prohibited to install gas or oil heating systems and by 2040 there should be no more gas/oil heating systems in Austria left.

Methodology

With our start-up idea we want to provide a direct solution for the big problems for heating. The initial idea is to create a seasonal heat storage on a large scale to supply several one-family houses or large apartment buildings, that makes it possible to reach a nearly energy-autarkic level heating system. After five rounds of improving our business model, with developing a technology that is feasible and some Interviews with experts for energy and renovation projects, we could create a 3D Model Prototype of our tank system.

Results

We created a system that can store the energy of the summertime for heating in the winter. For that we created a water-tank with an energy-store capacity of 20.000 kWh. The benefit of our system is not only that it is autarkic and sustainable but also is more efficient than other systems. With the use for bigger houses the tank gets bigger and so the volume surface ratio decreases, which leads to fewer losses. The plant itself is capable of saving up to 60% of the energy needed to heat apartments. Though the heat sales a transition towards a new heating system will also become profitable and attractive for house owners. The surplus of energy can then be sold to the residents. To guarantee a smooth heat delivery HEATST will take care of the maintenance of the system during its lifetime. In return, the value of 15% of the energy sold is paid to HEATST. Regardless of the share of energy sales, the breakeven point for the plant will still be achieved within 10 years for the owner. This ensures a financially viable and profitable outcome, incentivizing the adoption of sustainable heating systems that contribute to long-term savings and a positive return on investment.
