Heatset

What Heatset does

Heatset OÜ is an Estonian private limited company operating as an authorized sales and maintenance partner for Weishaupt, Europe's leading industrial burner manufacturer. The company is headquartered in Alliku village, Saue vald, Estonia, and serves industrial and commercial customers requiring high-capacity heating solutions across the country. Its portfolio covers the full Weishaupt burner range — from compact 16–550 kW WL5-WL40 small burners, through 55–12,000 kW WM Monarch series, up to 1200–17,000 kW WKmono monoblock industrial burners and 900–32,000 kW WK dual-block industrial burners — in gas, oil, and gas/oil combination variants.

The company operates a B2B sales-led go-to-market targeting industrial facilities (heavy industrial users, manufacturing, processing) as the primary segment, with commercial and small-industrial customers (16–550 kW applications) as a secondary segment. Revenue is generated through one-time burner sales, recurring maintenance contracts, custom solutions (including burners from other manufacturers, fuel conversions, and specialized equipment integration), burner configuration using modern exhaust gas analyzers, gas installation and pressure equipment supervision, and burner rental. Pricing is uniformly quote-based with no publicly disclosed rates, and customer acquisition relies on direct phone, email, and website inquiry channels, supplemented by digital advertising on Facebook, Instagram, YouTube, and Google.

The core technical differentiator rests on Weishaupt's patented 3LN and 4LN burner technologies, described as best-in-class, and a 24-hour spare parts delivery system that supports installed-base reliability. Heatset layers local technical expertise — described as decades of accumulated practice and training — onto this brand foundation, providing calibration, preventive maintenance, and regulatory compliance services for gas and pressure equipment. The business is single-geography (Estonia), with no disclosed headcount, revenue, funding, parent company, or M&A activity in the available data.

Expansion highlights4 records

Direct peers

• Dreizler: Dreizler is a German manufacturer specializing in industrial gas burners and combustion technology for high-temperature processes. Comparable in industrial burner specialization and European service-and-distribution go-to-market to Heatset's authorized-partner model.
• Baltur: Baltur is an Italian industrial burner manufacturer offering gas, oil, and combination burners across a wide kW range with a European service and distribution network. Highly comparable in product offering and target industrial heating customer base to Heatset's Weishaupt portfolio.
• Saacke: Saacke is a German manufacturer of industrial burners, combustion systems, and firing plants for industrial process heat. Directly comparable in industrial burner focus, kW range, and service-heavy business model to Heatset's core offerings.
• Riello Burners: Riello is a major Italian/European manufacturer of gas, oil, and dual-fuel burners across residential, commercial, and industrial capacity ranges. Heatset competes by servicing and distributing the competing Weishaupt brand, but the customer base, application set, and burners offered are directly comparable.
• Oertli: Oertli is a European (Swiss-origin) manufacturer of heating burners for residential, commercial, and industrial applications. Comparable product range, technology positioning, and target customer segments to Heatset's Weishaupt burner offering.
• Eclipse (Eclipse Fuochino / Eclipse Inc.): Eclipse manufactures industrial combustion equipment including burners for process heating applications across a wide power range. Directly comparable in industrial burner manufacturing and service-heavy business to Heatset.

Others

• Weishaupt: Weishaupt is Heatset's core product and technology supplier — the manufacturer of the WL, WM, WKmono, and WK burner series Heatset distributes and services. As Heatset's enabling partner providing the underlying product, brand, technology patents, and 24-hour spare parts supply, Weishaupt is ecosystem-enabling rather than directly competing with Heatset in Estonia.

Broad incumbents

• Bosch Thermotechnology: Bosch Thermotechnology is a broad-established European heating and hot-water solutions provider covering residential, commercial, and industrial heating including burner-based systems. Larger and more diversified than Heatset, with overlapping industrial burner capability as part of a wider heating portfolio.
• Viessmann: Viessmann is a broad European incumbent in heating, industrial, and refrigeration systems, including burner-based industrial heat generation. Larger and broader in scope than Heatset, but addresses the same industrial heating customer base with overlapping burner technology.
• Kromschröder / Elster (Honeywell): Kromschröder (now part of Honeywell/Elster) supplies industrial gas combustion and burner control technology across Europe. Overlaps with Heatset on burner regulation and gas installation components within a broader combustion and metering portfolio.
