What It Is

Heat-Box is specialized calculation software for the HVAC industry, focused on design work related to heating, cooling, domestic hot water, and ventilation. According to the website, it can quickly generate standards-compliant heat-loss calculations and produce professional reports with a company-branded look. In the Flanders region, PRO-level building and room-level calculation reports can be used as an EPB stavingsstuk — supporting documentation for scenarios such as low-temperature heating.

Core Features and Standards Support

The core product is heat-loss calculation, available in two versions: EASY and PRO. EASY is intended for the quotation stage and provides a quick estimate in around 5–10 minutes. PRO follows NBN EN 12831-1, typically taking around 30–60 minutes for a standard home, and is suitable for execution-stage design and EPB documentation. The software also supports underfloor heating calculations, including pipe spacing, floor temperature, number of circuits, pipe length, and regulated flow rate. Radiator selection is supported through built-in databases from brands such as Radson, Jaga, and Vasco. Other modules include domestic hot water storage tank sizing based on NBN EN 12831-3, cooling load calculations based on NEN 5067, and ventilation layout drawings for homes and small offices.

Pricing, Trial, and Integrations

The captured content does not disclose specific plans, pricing, or payment methods, but the website offers multiple options to request a free trial or demo. To request a demo, users need to provide a contact name, company, email address, and phone number; the company says it will get in touch within 2 business days to arrange an online meeting. In terms of integrations, the site explicitly mentions the ability to import EPB reports, which can save up to around 50% of data-entry time. It also improves selection efficiency through branded radiator databases. We did not find any mention of APIs, developer support, or deep integration with BIM/CAD platforms.

Pros, Cons, and Best-Fit Users

Its strengths are its highly focused use cases, clearly stated calculation standards, and reports that can be used directly for project communication and certain compliance documentation. It is well suited to HVAC installers, design consultancies, heat pump/boiler/radiator manufacturers, and distributors. The downside is limited disclosure around enterprise SaaS capabilities: there is no clear information on team permissions, data security certifications, deployment options, or pricing. The ventilation module is also explicitly not suitable for complex projects such as large hospitals. Its standards framework is oriented toward Belgium and Dutch-speaking markets, so projects in other countries should verify applicability carefully.

Access from China and Alternatives

Access from China cannot be determined from the available text, and both the product language and applicable standards are clearly aimed at the European market. Even if accessible, Chinese users may still face issues around local payment, Chinese-language support, and compatibility with Chinese standards. Users in China would likely be better served by first evaluating tools such as T20 HVAC, Hongye HVAC, Glodon, PKPM-related tools, or Revit combined with local HVAC calculation workflows.
