Owner of Bobaas Donkies, Johan Maritz, has over 30 years of experience working in the general steelwork industry, primarily producing security gates, entrance gates, fencing, burglar bars, and other steel products. 

Looking for a highly durable, and affordable off-grid water heating solution, Johan initially designed and created the BBD prototype in  2018, and since then, the original design was only changed twice. The positive feedback and response from clients pay testimony to the effectiveness, and great quality of the product! 


What is a donkie?

A Bobaas Donkie is an off-grid, hot water system, or a domestic water heating appliance that uses a water storage tank (100l, 150l or 200l) to maximize heating capacity, and provide instantaneous delivery of hot water to a variety of applications, including farms, lodges, hunting camps, bush camps and normal households. 

Because we are committed to creating high-quality products, we place a lot of emphasis on the manufacturing process, and since maintaining a very high standard of customer service is also a top priority, we go to great lengths to ensure customer satisfaction.

How does it differ from other products?

Whereas conventional storage water heaters use a variety of fuels, including electricity or gas, our water heating technology uses wood only, and when used with a geyser blanket, it can result in less dependency on grid energy, and subsequently, huge monthly savings on your electricity bill. Remember, you only need a small fire!

It is recommended that the unit be placed outdoors. A simple foundation (such brick/paving or a concrete slab) can be laid to secure the installation of the unit. The foundation can also be raised, for more convenience when making a fire. Bobaas Donkies is recommended to be used as a ‘stand-alone’ unit and it is highly recommended that a qualified/certified plumber do to the installation, for safety purposes. It is essential that every installation complies to SANS 10254, just like any other electrical, gas or solar geyser. 

With a Bobaas Donkie, you can have warm water in half an hour (30 minutes), and really hot in 45 minutes with the minimum amount of dry wood pieces (for the device with a 100-liter capacity). 

Warning: Never touch the surface of the unit while in operation, as it will become very hot. The unit should only be operated by an adult.
