Cylinder / Storage

Reliable Cylinder & Storage Water Heaters for Your RV

Ensure you always have a steady supply of hot water for showers and dishes with our premium range of storage water heaters. Unlike instantaneous califonts, these systems use an insulated cylinder to keep a reservoir of water (typically 10L to 22L) at a constant, preset temperature. This "ready-to-go" hot water is a favourite for New Zealand caravanners who value consistent temperature and the ability to use multiple heat sources.

Our collection features the most trusted names in the industry, including Suburban, Truma, Isotemp, and Gas Quip, all engineered for the unique rigours of mobile travel in NZ.

Gas, Electric, and Mixed-Mode Versatility

Most of our storage water heaters offer multiple energy options, allowing you to tailor your hot water usage to your location:

• Gas-Only Models: Ideal for freedom camping, these units use a powerful burner to heat your water quickly using only LPG.
• Gas/Electric (230V) Combinations: The most popular choice for NZ travellers. Save your LPG by using the internal 230V electric element when plugged in at a motorhome park, or use both gas and electric simultaneously for a "boost" mode to achieve rapid recovery times.
• High Insulation: These cylinders are wrapped in high-density foam insulation, ensuring that almost no heat is lost once the water reaches temperature.

Marine-Grade and Heat Exchange Options

For boat owners and specific campervan setups, we also stock Isotemp water heaters. These specialised marine-grade cylinders often feature a heat exchanger, which connects to your vehicle's engine cooling system. This allows you to heat your water "for free" while you are driving or motoring, with a 230V element as a backup for when you are stationary.

Essential Maintenance: Anodes and Safety

To keep your water heater in top condition and protect your investment, regular maintenance is required. If you own a Suburban porcelain-lined tank, it is essential to check and replace your Anode Rod annually. This rod absorbs corrosive elements in the water to prevent the tank from rusting.

Note: In accordance with New Zealand safety standards, all gas-powered water heaters must be installed and certified by a registered gas fitter. This ensures correct flueing and prevents hazardous gases from entering your living area. Browse our range today and invest in a hot water system that makes every NZ road trip a luxury.
