Also connect to an open loop solar system or hot water heat pump using the eco inlet connection.
Wetback is something that is mostly associated with an old house with a low pressure copper cylinder connected to an old wood burner. With a Rinnai thermosiphon cylinder you can now have a new modern house with mains pressure water heated by your wetback fire, saving you money on your power bill.
Choose from either a 190, 250 or a 300 L cylinder.
Thermosiphon coil for wetback
The water is circulated through a coil inside the cylinder by a thermosiphon effect i.e. warmer water rises and cooler water falls, creating a natural flow. This means there is no need for a pump to circulate the water, you can still heat your water even if there’s a power cut!
Designed for high temperatures
The duplex stainless steel inner cylinder means it can be used in solar systems with high incoming water temperatures.
The eco inlet also allows you to connect to an open loop (potable) solar system, or a hot water heat pump.
Peace of mind
This range of electric mains pressure hot water cylinders comes with a 10 year warranty, and is backed by Rinnai after sales service and support.
* Refer to the owner and installer guide in the 'Technical' tab for full warranty details.
** For open loop solar systems the potable (water suitable for drinking and food preparation) from the cylinder flows through the collector—water that flows through the system is used directly by the household.
• Indoor installations
• Mains and low pressure systems
• Connection to a wetback fire and/or an open loop solar system or hot water heat pump
• Residential and light commercial water heating applications
Not suitable as a pool or spa heater, or for underfloor heating.
Rinnai water heaters are manufactured to suit most New Zealand council water supplies. However some water supplies can have a detrimental effect on the water heater, its operation and life expectancy. Stainless steel cylinders are not suitable for bore or tank water.
Single thermosiphon coil lower element
For new builds and renovations connecting to a wetback fire, where the homeowner will have full electric boost when there is not enough heat from the wetback fire. System can also be connected to an open loop solar system or hot water heat pump.
Single thermosiphon coil dual element
For new builds and renovations connecting to a wetback fire, where the homeowner wants faster recovery times, and to reduce the risk of running out of hot water. Cylinder will have higher running costs. System can also be connected via the eco inlet to an open loop solar system or hot water heat pump.
Single thermosiphon coil upper element
For new builds and renovations connecting to a wetback fire, where the homeowner relies heavily on heat from the wetback and/or open loop solar system or hot water heat pump. Upper element is only used to quickly heat water in the top of the cylinder.
