iHeat – digitally planned from the outset
iHeat is a young, nationwide company specializing in heating and solar technology. Since its inception, iHeat has been working with autarc to efficiently and digitally map the entire process from the initial inquiry to the final planning. Whether heat pumps or PV – all projects are implemented with precise building data, standard-compliant calculations, and fully digital customer processing.

Challenges facing autarc
High costs for building data
From the outset, iHeat required a digital solution to reliably and uniformly record room data and heating surfaces for projects throughout Germany.
Slow bidding processes
With the start of PV planning, the quotation process became more extensive. iHeat therefore needed a digital solution that could map heat pump and PV projects in a uniform process.
Complexity of funding applications
As a digital provider, iHeat wanted to process subsidy applications efficiently, accurately, and correctly throughout Germany—without complicated Excel spreadsheets or manual research.
Availability in customer support
With customers from all over Germany, the team reached its limits: requests came in at different times, and it took a long time to document them in a structured manner.
