Frequently Asked Questions - wood-fired Hot Water Bega Valley.
Can I connect a thermosyphon system to my existing wood heater or stove?
In many cases, yes – provided your heater has a wetback fitting or can be retrofitted with one, and the storage tank can be positioned correctly above it. Patrick will assess your existing heater and property layout during the free site visit and confirm whether a connection is practical or whether a new setup is the better option.
What happens to my hot water in summer when the fire isn't lit?
This is the most common question about wood-fired systems. The cleanest solution is to add a solar boost – solar panels are plumbed into the same storage tank and heat your water through spring and summer when the fire isn’t running. Alternatively, a small electric boost element can be added to the storage tank as a backup for occasional use. Patrick will talk you through both options.
Does the thermosyphon system need electricity to work?
No. The thermosyphon principle relies entirely on natural convection – hot water rises, cooler water falls – with no pump or electricity required. This makes it one of the very few genuinely off-grid capable hot water systems available. The only electricity involved would be if you choose to add an electric boost element as a summer backup.
Does the storage tank have to be above the wood heater?
Yes – this is fundamental to how a thermosyphon system works. The tank must be positioned higher than the wetback coil for water to circulate naturally through the system. Patrick assesses tank placement during every site visit and designs the pipe runs to ensure correct gradient and flow.
Is a licensed plumber required to install a thermosyphon system?
Yes – a licensed plumber is legally required to install any wetback or thermosyphon hot water system in NSW. It is not a DIY job. Patrick holds NSW Plumbing Licence No. 5731 and carries full insurance. All work is completed to Australian Standards.
Is a wood-fired thermosyphon system suitable for a new build in the Bega Valley?
Absolutely – new builds are an ideal opportunity for a thermosyphon system because the tank location and pipe runs can be designed into the build from the start. If you’re building in the Bega Valley and want to explore wood-fired hot water with or without a solar boost, get in touch with Patrick early in the planning process.
