Mains Pressure Indoor Single Thermosiphon Wetback Coil

A thermosiphon coil allows you to have a mains pressure cylinder connected to a wetback fire

Wetback is something that you mostly associate 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.

Thermosiphon coil for wetback
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 water, you can still heat your water even if there's a power cut.

Eco inlet
Added benefit of an eco inlet that allows connection to an open loop* (potable) solar system, or a hot water heat pump.
