All also will recommend 4mm as per ST guidelines. 2.5mm proper cable can still use lah if its 3kW class (divide the 3800W by 230V to get amps 16.52 A). Still within 21A max current capacity of quality 2.5mm² cable. If substandard cable then another story lah.
Quality cable meaning SIRIM approved MS2112:3 compliant cable for the ones concealed in the wall.
Quality cables will print the spec and certified to MS standard blablabla not just to show off, but its a requirement as PVC cables are controlled items -see https://www.st.gov.my/en/contents/files/dow...ble_testing.pdf. Those that never print are suspicious.

Fake certification on cable also a problem here in Bolehland - https://www.sirim-qas.com.my/forgery-on-license-no-pc000218/
You should NOT use a 4.8kW class heater with 2.5mm² cable as it is running at redline for 2.5mm² cable.
