 What’s Good — Where it Fits

• Affordable “instant-hot water” solution: Since it’s a 4.5 kW water heater and non-tank, it’s suitable if you want hot water for showers without needing a big storage tank or bulky system.

• Compact & simple: Tankless design means less space used; easier installation than storage-type heaters.

• Basic but solid safety & heating spec: Offers essential safety protections (thermal cut-off, proper materials), reasonable heating power for household shower needs.

• Works if your water pressure is sufficient: As long as your water supply meets the minimum pressure requirement (~9.8 kPa), it should heat water properly.
