How does the Central gas water heater Work? From Flame to Floor
The mechanism is simple yet powerful. When the thermostat detects a temperature drop, the gas valve opens and the burner ignites. Heat rises through a central flue to heat the water. This process explains why the Central gas water heater vs electric recovery speed is much faster, making gas the ideal choice for continuous hot water.
- For Domestic Use: Hot water is pumped to showers and kitchens.
- For Heating: The heater acts as a “Boiler,” circulating hot water through a network of pipes under the floor (Underfloor Heating) or through radiators to provide consistent, healthy warmth without drying out the air.
Central Gas Water Heater Installation Requirements
To ensure safety and longevity, Greenwell follows strict international standards:
- Venting System: Must have a dedicated chimney or stainless steel flue to exhaust CO2.
- Gas Pressure: Requires a stabilized gas line with a dedicated regulator.
- Location: Should be installed in a well-ventilated area (roof or dedicated mechanical room).
- Drainage: A floor drain must be available for the pressure relief valve and tank flushing.
- Expansion Tank: Essential to absorb water pressure increases during heating cycles.
Benefits & Importance of Central gas water heater
- High Volume: Provides thousands of liters of hot water daily.
- Dual Purpose: One unit handles both bathing water and home heating. The central gas heater acts as a Dual-Purpose unit, providing domestic hot water and supporting Underfloor Heating systems through efficient heat exchangers.
- Cost Efficiency: Natural gas is up to 60% cheaper than electricity for large-scale heating.
- Reliability: No “cold spots” in the house and works during power outages.
