Ferroli GS 20 OE BIP TG water heater replacement at Starlight Suites - 29 May 2024


Replaced Ferroli GS 20 OE BIP TG Gas Heater at end of service life.


Replaced Rinnai REU-2024W-RS and corroded sections of cold water copper piping with new piping. Utilised single-use fittings during the replacement to ensure optimal joint integrity. Reconnecting old fittings again risks erosion, particularly in high-speed water systems, and raises the chance of corrosion in water and gas piping. This increases the risk of water or gas leaks. Replaced the faulty cold water sensor as part of overall maintenance to ensure optimal functionality.

The final result

Old gas heater:

Ferroli GS 20 OE BIP TG

The Ferroli GS 20 OE BIP TG Gas Heater is a product manufactured by Ferroli.
Ferroli is an Italian company known for producing heating and air conditioning systems.
Here are some general details about this gas heater:
1. Type:  The GS 20 OE BIP TG condo model is an outdoor gas water heater with a weatherproof body for installation on the external AC ledge of buildings.
It provides instantaneous hot water with a flow rate of 20 liters per minute.
Capable of supplying hot water to four points of usage.
Comes with a digital wired remote control for easy operation.
Features hydraulic-type pulse ignition for efficient starting.
Utilises forced exhaust for optimal performance.
Includes a built-in pump, allowing water to be pre-heated in a hot water pipe loop to reduce wastage, especially in larger apartments with hot water usage points more than 10 meters away from the heater.
2. Installation: Proper installation is crucial for safety and optimal performance.
Gas heaters need professional installation for proper venting, gas line connections, and compliance with safety standards.
3. Safety: Ensure gas heater safety to prevent accidents like fires, gas leaks, or carbon monoxide poisoning.
Following manufacturer instructions and ensuring proper ventilation is essential for safe operation.


New gas heater: Rinnai REU-2024W-RS

The Rinnai REU-2024W-RS is a gas water heater manufactured by Rinnai, a well-known brand in the heating and water heating industry.
Founded in 1920, Rinnai & Co. first manufactured and sold pressurized oil stoves.
By the late 1920s, it was a reliable maker of gas tabletop stoves, ovens, heaters, and hot water units.
The Rinnai REU-2024W-RS is an outdoor gas-fired water heater. It’s weatherproof for external installation and suitable for AC ledges.
It provides a flow rate of 20 liters per minute. It offers hot water to four points simultaneously.
Here’s some information about its type, efficiency, and safety features:
1. Type: The REU-2024W-RS is a gas-fired instantaneous water heater, meaning it heats water on demand as it flows through the unit, rather than storing hot water in a tank.
This ensures a continuous supply of hot water without the need for storage, making it an efficient choice for many applications.
2. Efficiency: While specific efficiency ratings may vary depending on factors such as installation and usage conditions, gas-fired instantaneous water heaters like the REU-2024W-RS are generally known for their high efficiency.
By heating water only when needed, these units avoid the standby heat losses associated with traditional tank-based water heaters, resulting in potential energy savings for the user.
3. Safety Features: Rinnai water heaters typically come equipped with various safety features to ensure safe operation.
Gas heaters should always be used with caution to prevent the risk of fire, carbon monoxide poisoning, or other hazards.
Following manufacturer instructions and ensuring proper ventilation is essential for safe operation.
