Unionaire iHeat Digital Gas Water Heater – 10 L – White (UGH100D-WT)

The Unionaire iHeat 10 L (UGH100D-WT) is a compact, instant gas water heater that delivers dependable hot water at a single outlet while saving wall space. The clean white fascia and digital temperature display keep control simple, and the chimney configuration supports proper venting for safe, tidy installation in small bathrooms and kitchens.

Purpose-built for everyday reliability, iHeat features automatic ignition triggered by water flow—no standing pilot—so you get hot water on demand. Manual water and gas adjustment helps you fine-tune comfort across seasons, while the unit’s full safety protections are designed to shut down operation under abnormal conditions. Retailer listings confirm the Natural Gas (NG) variant and note availability of chimney and a slim body around 330×185×650 mm, making it easy to place above a sink or beside a shower.

For best results, match the heater to your gas supply (NG; some markets offer LPG/convertible versions—confirm on the rating label), ensure compliant ventilation and flue routing, and periodically clean the inlet filter. With its digital feedback, instant start, and space-saving 10 L format, the Unionaire iHeat keeps running costs in check while providing consistent hot water for everyday use.
