heimWatt Tech Stack

Heat pump and solar installer with digital order management in Northern Germany

Services for Renewable Energy Salzhausen, Niedersachsen 51–200 employees Founded 2020 Public Company

heimWatt installs heat pumps and photovoltaic systems across Northern Germany, operating a 51–200-person business founded in 2020. The tech stack is almost entirely no-code/low-code (n8n, Zapier, Make, Airtable, HubSpot, Personio) — no custom engineering infrastructure — which maps directly to their pain-point focus: process automation, order management, and cross-team communication. Active hiring is concentrated in engineering (12 roles), suggesting they're moving toward custom tooling to replace the workflow orchestration layer.

About heimWatt

heimWatt designs and installs heat pumps and solar systems for residential and commercial customers in Northern Germany. The company operates a vertically integrated model spanning system design, installation, and ongoing energy management. Core functions include installation teams (SHK trades), order management and logistics, customer service, and sales expansion. The business model is capital-intensive and field-heavy, reflected in the hiring mix: engineering roles outnumber sales 12-to-5, and active projects span both hands-on installation (Wolf heat pump deployment, radiator replacement, inverter setup) and internal operational scaling (digital order processing, partner ecosystem, sales data tools).
