Choosing the right range hood depends on your market's cooking habits and kitchen design. For Asian markets with high-heat wok cooking, choose powerful wall mount or ceiling mount hoods (airflow 800+ m³/h). For European markets, slim built-in or telescopic hoods suit modern minimalist kitchens. For commercial kitchens, opt for canopy hoods or island hoods with heavy-duty filters. HouseTech offers various extraction capacities from 400 m³/h to 1200 m³/h to meet different requirements.

Gas Stoves: Use natural gas or LPG, provide instant heat control, preferred in many Asian and European markets. Ceramic Cookers: Use radiant heating elements beneath a smooth glass surface, easy to clean, medium heat control. Induction Cookers: Use electromagnetic technology, most energy-efficient (90%+ efficiency), safest option with automatic shut-off when no cookware is detected. Each type has specific certification requirements depending on your target market regulations.

Voltage requirements vary by region: 110V/60Hz is standard in North America, Japan, and some Latin American countries. 220V/50Hz is used in Europe, Asia (including China), Africa, and Middle East. HouseTech products can be customized for either voltage. For dual-voltage products (110V/220V), we use universal motors and heating elements that work in both systems. Always specify your target market's voltage requirements when requesting a quote to ensure compliance.

Market-specific certifications: Europe: CE marking (mandatory), includes LVD, EMC, ErP directives. North America: ETL or UL listing required for electrical safety. Middle East: SASO certification for Saudi Arabia, GCC certification for UAE, Bahrain, etc. South America: INMETRO (Brazil), IRAM (Argentina). Asia: PSE (Japan), KC mark (Korea). HouseTech can advise on and arrange necessary certifications. Contact our sales team with your target market for specific certification guidance.

Built-in Ovens: Installed into kitchen cabinetry for a seamless look, typically 60cm or 90cm wide, popular in modern European-style kitchens. Freestanding Ranges: Stand-alone units with cooktop and oven combined, often preferred in American and Asian markets. HouseTech offers both types with various capacities from 45L to 100L. Built-in models require precise cabinet measurements, while freestanding units offer easier installation flexibility.

Instant (Tankless) Water Heaters: Heat water on-demand, no storage tank required, compact size, energy-efficient as no standby heat loss, ideal for point-of-use installation. Storage Water Heaters: Store and pre-heat water in a tank (10L-100L), provide continuous hot water supply, better for multiple usage points simultaneously. Choose instant for small apartments or single-bathroom installations; choose storage for larger homes or commercial applications with higher hot water demand.
