Before ordering a Rinnai hot water system or part, check the existing unit and compare the product specifications carefully. Rinnai hot water products can vary by fuel type, flow rate, capacity, dimensions, pressure rating, connection layout and required accessories.
Check these details before buying:
Rinnai model number
System type
Natural gas, LPG or electric requirements
Storage capacity in litres
Flow rate in L/min for continuous flow units
Water pressure rating in kPa
Hot and cold water connection locations
Inlet and outlet connection sizes
Indoor, outdoor or external suitability

Delivery access for larger products

If you are replacing an existing Rinnai unit, matching the model number and key specifications is the safest way to reduce ordering mistakes.
Rinnai continuous flow hot water systems heat water as it passes through the unit instead of storing heated water in a tank. These systems are commonly selected by customers who want a compact hot water option and are usually compared by flow rate in L/min.
When comparing Rinnai continuous flow systems, check the fuel type, flow rate, temperature settings, connection positions, dimensions, power requirements and whether the unit is suitable for the intended location. Natural gas and LPG models are not the same, so always choose the correct gas type before ordering.
Rinnai gas hot water systems may include continuous flow or storage-style options, depending on the products available in the collection. Gas systems must be matched to the correct fuel type, either natural gas or LPG.
Rinnai electric hot water systems are often selected for storage hot water replacement, apartments, smaller homes and properties where electric supply is preferred.
Rinnai heat pump hot water systems may suit customers looking for an energy efficient storage hot water option, using heat from the surrounding air to help warm water in the tank.
The right Rinnai system depends on the property, hot water demand, available space, power or gas supply, pressure rating and product specifications.
A Rinnai hot water order may require more than the main system. Valves, pipework, fittings and accessories can be needed to suit the water pressure, connection layout and system requirements.
Common products used with Rinnai hot water systems include:
Tempering valves
PTR valves
Pressure limiting valves
Expansion control valves
Isolation valves
Non-return valves
Duo valves
Hot water connection kits

The right Rinnai hot water system depends on your household size, hot water usage, available gas or power supply, space, water pressure and preferred system type. Storage systems are usually compared by litres, while continuous flow systems are compared by flow rate in L/min.
Natural gas Rinnai hot water systems are designed for properties connected to mains natural gas. LPG Rinnai hot water systems are designed for bottled gas. They are not interchangeable unless the product is specifically designed or converted for that fuel type, so always choose the correct version before ordering.
Rinnai continuous flow systems are generally compared by flow rate in L/min rather than tank capacity. The right flow rate depends on household demand, number of outlets, climate, incoming water temperature and product specifications.
You may be able to replace an existing Rinnai system with a newer Rinnai product where the specifications, fuel type, water connections, pressure rating, dimensions and product requirements are suitable. Always compare the current model details with the new product before ordering.
New valves may be required depending on the system type, existing valve condition, pressure rating and connection layout. Common hot water valves include tempering valves, PTR valves, pressure limiting valves, expansion control valves, isolation valves and non-return valves.
Check the model number, part number, fuel type, connection size, pressure rating, voltage where relevant and product compatibility. Matching the details from the existing unit or part helps reduce ordering mistakes.
