Every unit manufactured and supplied by Bobaas Donkies comes standard with a SABS-approved safety valve, with compression outlet (400 kPa pressure rating). This red-indicator valve acts as a dual-purpose safety valve – to relief overheated water, and to relieve excess water pressure.
Combo Valve = R600

We are very excited to offer an upgraded safety valve option for our fire-heated water heaters, enhancing safety, convenience, and ease of use for our clients. (Not recommended for use with pressure pumps)
Spark Arrestor (made from stainless steel mesh - R600)

Spark Arrestor
Our spark arrestor is a safety accessory that fits securely over the chimney pipe of your Bobaas Donkie wood-fired water heater. It is designed to catch and prevent hot sparks or embers from escaping the chimney, reducing the risk of fire—especially in dry or grassy areas. We highly recommend this add-on for extra peace of mind when operating your unit near flammable materials or during windy conditions.
Key Features of the New Safety Valve (Priced at R600):
3-Bar Safety Release Valve: Automatically releases pressure when it exceeds 3 bars to prevent overheating or damage.
Integrated Pressure and Temperature Gauges: Conveniently monitor system performance, ensuring optimal operation and safety.
Plug-and-Play Design: For existing users, the new valve and gauges are easy to install – just remove the old valve, and replace with the new combo-valve.
Pressure Tested for Reliability: Our wood-fired water heaters are pressure-tested to withstand up to 5 bars, ensuring long-term durability.
Compatibility with Municipal Water Supply: Designed for pumped water systems with average municipal pressures of 2.5 to 3 bar.
When pressure reaches 3 bars, the safety valve vents to release excess pressure. We strongly recommend installing a breathing/discharge pipe directed towards the ground or a waterway for proper operation, which can be done by a professional plumber.
STANDARD OPTION:
For those seeking a simpler solution, we continue to offer our standard safety valve, which includes:
4-Bar Pressure Valve: Provides safety at higher pressure thresholds but lacks the advanced monitoring features.
No Integrated Gauges: Monitoring requires separate tools.
Why Upgrade?
The new Combo-valve not only provides enhanced peace of mind with built-in gauges for easy monitoring but is also designed for hassle-free installation. Current users can quickly upgrade their system with our plug-and-play design. Choose the safety solution that best suits your needs and ensure your water heating system operates at its best!
DO I NEED AN ANODE ROD?
Where poor quality is a concern to clients, for example, where there is a lot of impurities/chemicals in the water, or in instances where the household hot water usually usually turns a brown colour when the tap is opened, we would typically recommend an anode.
At an additional cost, we can fit any unit with a sacrificial anode rod, but we need to state that there is no guarantee, nor any specific assurance that the anode provided will resolve problems as a result of poor water quality.
The anode is said to be "self-sacrificing" because it serves as a corrosion magnet to keep the geyser tank from rusting, safeguarding the exposed metal parts of the geyser.
Because the rod has a larger current potential than other metals in the water heater, the anode is typically constructed of magnesium or aluminum wound around a steel core wire. This ensures that the galvanic current travels from the rod to other exposed metals, preventing their corrosion.
