Recently acquiring a 12-liter Autopro Hermes Green water heater, I encountered a situation where the number "12" intermittently appeared on the display when I turned on the hot water. This article aims to explore this issue, delve deeper into the specifics of the Autopro Hermes Green water heater, and provide a comprehensive overview of butane gas water heaters in general, touching upon various aspects including installation, maintenance, troubleshooting, and safety. The appearance of "12" on the display, while initially concerning, might be a simple code indicating a specific operational status or a minor issue. This article will help decipher such codes and guide you towards resolving any problems you might encounter.
Understanding the Hermes Autopro 12L Water Heater
The Autopro Hermes Green 12L falls under the category of CALENTADOR ESTANCO BAJO NOX GAS BUTANO, meaning it's a sealed, low-NOX emission butane gas water heater. These features are crucial for safety and environmental responsibility. Let's break down these terms:
* CALENTADOR ESTANCO: A sealed combustion chamber prevents combustion gases from entering the room, eliminating the risk of carbon monoxide poisoning. This is a vital safety feature, especially in bathrooms or other enclosed spaces. The exhaust gases are expelled safely to the outside via a flue.
* BAJO NOX: Low NOX (nitrogen oxides) emissions signify environmentally friendly operation. NOX gases are pollutants contributing to air pollution and acid rain. Low-NOX burners are designed to minimize their production.
* GAS BUTANO: This specifies the fuel source – liquefied petroleum gas (LPG) butane, commonly used in portable gas cylinders. This contrasts with natural gas (CALENTADOR GAS NATURAL 12L ESTANCO), which requires a permanent gas supply connection.
The 12L designation refers to the water heater's capacity, indicating it can store approximately 12 liters of hot water. This capacity is suitable for smaller households or apartments with moderate hot water demand.
The Mystery of the "12" Display
The appearance of the number "12" on your Autopro Hermes Green display is likely a code indicating a specific operational status or a minor fault. Unfortunately, without access to the specific user manual for your model, it's difficult to provide a definitive answer. However, several possibilities exist:
* Water Temperature Setting: The "12" might correspond to a specific temperature setting. Check your user manual for a table correlating display numbers to temperature levels.
* Error Code: In some models, numeric displays can signal error codes. Consult your user manual for a troubleshooting section outlining potential error codes and their solutions. Common issues might include low gas pressure, insufficient water pressure, or a problem with the ignition system.
* Diagnostic Mode: Some advanced water heaters have diagnostic modes activated by specific button combinations. The "12" could be part of a diagnostic sequence. Again, the user manual is your best resource.
Troubleshooting Steps:
1. Consult the User Manual: This is the most critical step. The manual should provide a detailed explanation of the display codes, troubleshooting procedures, and safety instructions.
2. Check Gas Supply: Ensure the butane gas cylinder is properly connected and contains sufficient gas. A low gas level can cause erratic operation.
3. Check Water Pressure: Low water pressure can also affect the heater's performance. Check your home's water pressure to rule out this possibility.
