Masser

What Masser does

Masser NV is a Belgian family-owned renewable energy company headquartered in Erps-Kwerps, founded in 1948, that designs, manufactures, installs, and services heat pump and electric heating systems for the residential market. The company's core product portfolio spans four heat pump architectures — Sol/Sol (direct expansion ground-source), Sol/Eau (geothermal ground-to-water), Eau/Eau (hydrothermal water-to-water), and Air/Eau (aerothermal air-to-water) — supplemented by thermodynamic hot water systems (Aquaplex 200, Aqua-A), electric supplementary heating (Bali/CES convectors, MASB off-peak accumulators), radiant floor panels, and a spare parts catalog. Reported COP values range from 3.9 to 5.07, with the proprietary Sol/Sol direct expansion technology eliminating circulation pumps and heat exchangers as a claimed efficiency differentiator.

The company operates a vertically integrated direct-sales model with no intermediaries: in-house technico-commercial representatives perform on-site consultations, an engineering bureau calculates heat losses and designs each installation, and Masser-employed certified refrigeration technicians execute installations and after-sales service under site-manager supervision. Coverage spans all three Belgian regions (Flanders, Wallonia, Brussels), with national reach including secondary cities such as Liège, Namur, Charleroi, and Bastogne. Marketing leverages the bilingual (Dutch/French) masser.be website, an annual booth at the Batibouw construction trade fair (stand 12.100), newsletter, and Facebook presence. The company holds CEBEC, AIT, and VINCOTTE certifications, qualifies customers for federal subsidies up to €8,000 per certified installation, and claims to have served over 100,000 families with 40,000+ ventilation systems and 1,000+ new heat pump installations per year.

Revenue is generated through four streams: (1) hardware sales of heat pump systems, (2) professional installation services, (3) maintenance/repair contracts executed by certified technicians, and (4) direct-to-consumer spare parts e-commerce plus electric supplementary heating products. Pricing is unit-based for parts (€18-€2,225 depending on component) and quote-based for full heat pump installations. Spare parts, thermostats, filters, and resistance elements form a recurring aftermarket revenue layer on top of the project-based installation business. Masser self-describes as the "undisputed Belgian market leader" in residential heat pump and geothermal solutions, with all products developed and manufactured in Belgium.

Core offering

Masser develops, manufactures, sells and installs residential heat pump systems (Sol/Sol direct expansion, Sol/Eau geothermal, Eau/Eau hydrothermal and Air/Eau air-source) along with thermodynamic hot water tanks, electric supplementary heaters (Bali/CES convectors, MASB accumulators, Panotherm radiant panels), mechanical ventilation, central vacuum systems and a full spare-parts catalog. The company delivers end-to-end service through its own engineering bureau, in-house certified technicians and after-sales maintenance contracts for Belgian homeowners.

Product overview

Masser is a Belgian company (founded 1948) offering a comprehensive portfolio of heating solutions centered on heat pump technology. The core product line consists of four heat pump types: Sol/Sol (direct expansion ground-source), Sol/Eau (geothermal ground-water), Eau/Eau (hydrothermal water-water), and Air/Eau (air-source). These are complemented by sanitary hot water systems (Aquaplex 200, Aqua-A), electrical supplementary heating (Bali convectors, CES convectors, MASB accumulators), and optional equipment (Panotherm radiant panels, central vacuum systems). The company also provides a full range of spare parts including filters, thermostats, heating elements, and boiler components. All solutions are 100% Belgian-developed and manufactured.

Products and services

• Heat Pump Sol/Sol (Grond-Grond / Ground-Ground direct expansion heat pump) Direct expansion ground-source heat pump that extracts solar energy stored in the ground through a network of refrigerant-filled buried pipes and transfers heat to the home via floor heating. Eliminates circulation pumps and heat exchangers. Targets Belgian residential new-build and renovation customers seeking fossil-fuel-free heating.
• Heat Pump Sol/Eau (Grond-Water / Ground-Water geothermal heat pump) Geothermal heat pump that extracts heat stored in the soil and transfers it to living spaces via floor heating, with reported COP values of 4.84-5.07. For Belgian homeowners replacing or installing heating in new construction or major renovation.
• Heat Pump Eau/Eau (Water-Water / hydrothermal heat pump) Water-source hydrothermal heat pump extracting heat from groundwater, wells or streams (where temperatures oscillate between 7°C and 12°C), with COP of 4.08-4.22. For Belgian homes located near a viable water source.
• Heat Pump Air/Eau (Lucht-Water / air-to-water heat pump) Aerothermal air-to-water heat pump that draws heat from ambient air and delivers it to the home via floor heating. Requires no drilling or excavation, with COP of 3.9-4.1. For residential customers who cannot install ground or water loops.
• Aquaplex 200 Thermodynamic Boiler 200-liter thermodynamic boiler that extracts heat from ambient air to produce domestic hot water, with integrated anti-legionella system. For Belgian households needing renewable domestic hot water.
• Aqua-A Air-Source Hot Water System (A2 / A3) Air-source thermodynamic system for sanitary hot water production using ambient air as the cold source; available with a 210-liter (A2) or 270-liter (A3) tank, with ~70% of required energy drawn freely from air. For residential customers.
• Masser's electric supplementary heating range (Bali convectors, CES convectors, MASB accumulators, Panotherm radiant panels) Electric supplementary / complementary heating products — flat-front Bali and CES convectors, dynamic MASB off-peak accumulators and 75 mm Panotherm PA36/PA18 radiant floor panels (for large volumes such as churches or halls). Used as auxiliary heating or where heat-pump-only heating is insufficient.
