Recently, the "Line Fault" indicator of my 6 years old Alpha Smart 18EP instant shower water heater in one of my bathrooms had changed from its usual green light to red light. This is the same shower heater that was repaired in 2017 before.
I have replaced it with a new Joven SL30iP shower heater with DC inverter pump.
I bought the model without rain shower head for a cheaper price at around RM440, and managed to use back the rain shower head of the replaced Alpha Smart 18EP.
I have chosen Joven SL30iP this time, because:
- It has a very high performance/cost ratio, even higher than Alpha Smart 18EP.
- While the Alpha Smart 18EP has an AC pump, this Joven SL30iP has a DC inverter pump, which is much silent and saves electricity. More importantly, DC pump is less prone to electric shocks than AC pump.
- It has a built-in double poles Electronic Earth Leakage Sensor (EELS) with a very good 10mA sensitivity.
- It supports a lower minimum water pressure at 10kPa / 1.45 psi / 0.1 bar.
- It supports a lower minimum water flow at 2 litres per minute.
The only thing I don't like about this Joven SL30iP instant shower water heater is that its pump on/off switch, EELS test switch and EELS reset switch are located at its side instead of its front, making it harder to locate the right switch you want to press on.
Note that the water inlet and outlet of this Joven SL30iP are on the opposite side compared with the Alpha Smart 18EP. If you connect its water inlet and/or outlet on the wrong side, the water heater will not operate.
Same with Alpha Smart 18EP, the casing of this Joven SL30iP is IP25 splash proof.
If you are surveying on your new instant shower water heater, perhaps you can consider this one.
