125L Hot Water Cylinders

Hot water cylinders come in two types, direct and indirect, giving you the flexibility to match your system setup. A direct hot water cylinder has a built-in immersion heater to warm the water, making it ideal where no external heat source is available. An indirect hot water cylinder works with a boiler or other external system for integrated performance. For modern systems, an unvented hot water cylinder provides strong water pressure and a consistent supply, making it a popular choice for domestic and commercial installations. At Builder Depot, you’ll find a range of direct and indirect unvented hot water cylinders from trusted brands like Heatrae Sadia and Main, all built for reliability and performance.
