Paloma PH-16SX gas heater replacement at The Lakeshore - 20 May 2024


Replaced Paloma PH-16SX Gas Heater at end of service life.


Replaced Ferroli GS 20 OE TG (I) 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.

New gas heater: Ferroli GS 20 OE TG (I)

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.
