Confused about which geyser to buy? Here’s a simple guide to help you choose the right UNIGAS geyser for your home whether you live in a high-rise, use tanker water, or face salty water issues.
Choosing a Geyser That Fits Your Home
Buying a geyser might seem simple until you realize how much depends on your home’s water type, pressure, and usage.
At UNIGAS, we’ve been helping families across Pakistan stay warm since 1968, and we know every household has unique needs.
Here’s how you can choose the right geyser that lasts longer, saves gas, and delivers consistent hot water year after year.
1. Know Your Water Type
Not all water is the same. In Karachi and many other cities, people rely on tanker or bore water, which often contains salts and minerals that can corrode regular tanks.
If your water is salty or comes from a tanker:
Choose a geyser with stainless steel or painted/powder coated E.G. sheet protection.
Try UNIGAS Standard Plus (for moderate use) or Super Deluxe and Supreme (for long-term salty water resistance).
2. Check the Pressure Rating
High-rise apartments and buildings have strong water pressure that can damage ordinary geysers over time.
Each UNIGAS model is tested to handle specific PSI (pressure levels).
If you live in a high-rise building:
Go for geysers that can handle 45 PSI or more:
UNIGAS Super, Super Deluxe → up to 45 PSI
UNIGAS Super Heavy, Supreme, Platinum → up to 60–75 PSI
This ensures your geyser performs efficiently even at the top floors.
3. Understand the Gauge (Thickness)
The “gauge” indicates how thick the geyser’s tank steel is. Lower numbers mean thicker metal and higher durability.
UNIGAS standards:
10 gauge = strong (for normal homes)
8 gauge = extra durable (for high pressure)
6 gauge = ultra-heavy duty (for long-term or high-rise use)
If you want a geyser that can last 10+ years, the UNIGAS Platinum (6-gauge) is your best choice.
4. Consider Maintenance & Longevity
Even the best geysers need care but UNIGAS designs make it easier.
Our G.I. and stainless-steel tanks are resistant to rust, and powder coating prevents corrosion.
Pro Tip: Drain your geyser once every 6 months to remove mineral buildup and keep it running efficiently.
5. Match Capacity to Family Size
Choosing the right capacity avoids gas waste and ensures enough hot water for everyone.
Small family (2–3 people): 25–35 liters
Medium (4–6 people): 40–55 liters
Large household: 60–70 liters
All UNIGAS models are available in multiple sizes to match your family’s needs.
Final Word
Every home is different but with UNIGAS, you don’t need to guess.
Whether you’re in a high-rise apartment, a coastal area, or using tanker water, there’s a UNIGAS model built exactly for your conditions.
