Why choose a Gas Geyser for Your Home or Solar Backup?

Save Money and Never Run Out of Hot Water — Even During Power Outs or Rainy Days

 

Instant and unlimited hot water

Never run out of hot water. Enjoy a continuous and reliable supply of hot water for showers, kitchens, and more—whenever you need it.

Always on – No electricity or sunlight needed

Unlike electric and solar systems, gas geysers work seamlessly through power outages and cloudy days, keeping your water hot no matter the conditions.

Efficiency – heat-as-you-go, no wasted energy

With on-demand heating, water is only heated when needed, reducing energy waste and ensuring optimal efficiency.

Tankless, no risk of burst geysers

Built with safety in mind, Dewhot gas geysers eliminate the risk and inconvenience of burst geysers and severe damage to your home.

Space saving and easy access

Compact indoor designs and outdoor options are available for optimal convenience while delivering instant hot water without bulky storage requirements.

Significantly more energy efficient than electric

Gas water heating is much more efficient than electric geysers because it only heats the water you use, instead of keeping a whole tank hot all the time.

Significantly lower setup costs than solar

Installing a Dewhot gas water heater is more affordable than solar water heating systems, offering a budget-friendly way to enjoy energy-efficient hot water.

Boost solar geysers in cloudy weather

The Dewhot solar-to-gas valve seamlessly integrates with solar water heating systems, automatically switching to gas when the water is not hot enough.

Save your costly solar batteries by reducing battery drain

Using electricity to heat water drains a lot of power and shortens your battery life. Switch to gas geysers to preserve your solar battery.

Gas Geyser FAQs

Dewhot offers a wide choice of indoor or outdoor, multi-tap or single-tap geysers in various sizes. To choose the perfect geyser, consider your household size, the number of bathrooms and water outlets (taps), whether you need to serve multiple taps at once, your water usage habits, and the flow rate of your taps. An average shower uses 8 to 12 liters of water per minute.

Follow these 2 easy steps to find the right model

  1. Determine your flow rate bucket test
    Watch the video on how to do the quick Bucket Test to determine the flow rate of your taps.
  2. Choose your geyser model tool
    Once you have determined the flow rate of your taps you can head to Dewhot’s Help Choose my Geyser Guide to determine the perfect geyser for your home.

 

Gas water heaters, also known as gas geysers, are popular for hot water heating because they are efficient, reliable, and affordable. They are also relatively easy to install and maintain. Here are some of the benefits of using a gas geyser:

Efficiency: Gas geysers are much more efficient at heating water than traditional geysers, which can save you money on your energy bills. Dewhot geysers are rated up to 88% energy efficient

Reliability: Gas geysers are reliable and can last many years with proper care. They are also less likely to break down than other types of water heaters, such as electric geysers.

Affordability: Gas geysers are relatively affordable to purchase and install. They are also much cheaper to operate than electric geysers.

Ease of installation: Gas geysers are relatively easy and quick to install. A qualified LPG installer will set up the gas and a plumber will connect your water.

Ease of maintenance: Gas geysers are relatively easy to maintain. They only need to be cleaned and serviced every few years.

The cost of a Dewhot gas geyser depends on the size and model and range from R2,195 to R16,670.

Gas Geyser Model Pricing

Added Long Term Cost Savings

Electric geysers preheat water, so when compared to gas, which instantly heats the water as you need it, the energy savings are huge. Dewhot’s gas geysers are 84-88% energy-efficient and will slash more than 30% off your water heating bill.

Dewhot gas geysers come in various models to cater to the needs of different households.

Dewhot’s fan-forced geyser model is ideal for larger households or homes with high hot water use. It can service multiple taps at once using a powerful fan to circulate the hot water and deliver an even flow with a consistent temperature regardless of the demand. These models have a temperature sensor which means they can also be used as a backup solution to heat solar water.

Our Constant Temperature geyser model is a great option for medium to large sized households. It can service multiple taps at once and uses a thermostat to automatically adjusts the water temperature to your desired setting, constantly delivering a consistent temperature.  These models also have a temperature sensor which means they too provide an ideal backup solution to heat solar water.

The Low-Pressure Eco-Flow geysers are designed to operate with very low water pressure. It has a special valve that prevents the geyser from turning off if the water pressure gets too low. This makes them ideal hot water heaters for camping or to use with gravity fed tanks.

Diaphragm-activated geysers are the oldest type of gas geyser. They work by using a diaphragm to control the gas flow. Diaphragm-activated geysers offer simple functionality at an affordable price.

The best gas geyser for your home depends on your unique hot water needs and budget. The Geyser Guide can quickly help you to identify the perfect geyser for your home based on the size of your family and the number of bathrooms in your home.

A certified LPG gas installer must install your Dewhot gas geyser to ensure a correct and safe installation.

Dewhot gas geysers can be purchased online from Dewhot’s website or authorised dealers. An authorised installer can help you choose and install the perfect geyser. Email us today, and we will connect you to one of our qualified installers within a few hours.
