The PRO R SLIM 40 (SHE) keeps the slim 353mm horizontal body of the 30L but steps up to 40 litres for higher demand in concealed ceiling installs. Enamelled-steel tank (tested to 16 bar) with a large magnesium anode and high-precision thermostat. Electric water-heater hookup in Singapore must be done by a licensed electrical worker — SparkFlow is BCA ME05 L1 registered, so every install is by-the-book for HDB and condo. WhatsApp us a photo of your current heater or the install spot for a fixed supply + install quote.
