Why we stock the Ferroli.
The Ferroli GS 20 OE BIP combines outdoor mounting with built-in preheat (BIP), so you get hot water the moment you turn the tap and keep the unit outside your living space. 20 L/min flow, no storage tank. Gas water heaters in Singapore must be installed by a PUB-licensed gas service worker — SparkFlow's team is licensed and HDB-compliant. WhatsApp us your gas type (PUB piped or LPG) and a photo of the current unit or install spot for a fixed supply + install quote.
