- Manufacturer: GM Modular
- Model: Aeris Plus 15L
- Type: Vertical storage water heater

- Tank: Glass-lined, with rustproof outer body
- Safety: Thermal cutout and multifunction safety valve
- Colour: White · ISI marked
GM Aeris Plus 15L is a BEE 5 Star vertical storage water heater in white — the top efficiency rating, which is the specification that matters most on an appliance you will run for the next decade.
Five stars is worth paying for on a geyser in a way it is not on many appliances. A storage heater keeps a tank of water hot around the clock, losing heat to the room continuously and reheating to compensate. That standby loss is where most of a geyser’s electricity actually goes — not in the initial heating. A 5-star unit has thicker, better insulation, so it loses less and reheats less often. Over years of daily use that difference compounds into real money.
The tank is glass lined, which is the standard defence against corrosion: a fused glass coating over the steel that stops water attacking the metal, and keeps the stored water clean. The outer body is rustproof. Safety is handled by a thermal cutout that disconnects the element if it overheats, and a multifunction valve that relieves pressure as water expands on heating — both essential rather than optional on a sealed pressurised tank.
At 15 litres it is the family size: enough for two showers in succession, or one longer one, where a 10 litre tank generally covers one.
Key Features
- BEE 5 Star rated: The highest efficiency band — less standby heat loss and lower running cost year after year
- 15 litre capacity: Two showers in succession, or one longer one
- Glass-lined tank: Fused coating protects the steel from corrosion and keeps stored water clean
- Rustproof outer body: Built for the humidity of a bathroom
- Thermal cutout: Disconnects the element if it overheats
- Multifunction safety valve: Relieves the pressure that builds as water expands on heating
- ISI marked and vertical wall mounted

Before Installation — Please Read
- Have it installed by a qualified electrician. A water heater is a high-wattage appliance in a wet area — this is not a DIY fitting
- An earthed connection with an ELCB or RCCB is essential on any water heater circuit
- Check your circuit rating before installation — confirm the existing wiring and MCB can carry the load
- Hard water shortens heater life. Scale builds on the element and tank; periodic servicing makes a real difference in Bengaluru
- Living in a high-rise? Check the pressure rating before ordering — upper-floor supply pressure can exceed what a standard heater is built for, and a pressure-reducing valve may be needed
1) Is a 5 star rating actually worth the extra cost on a geyser?
On a storage water heater, yes — more than on most appliances. A geyser keeps a tank hot around the clock, and that standby loss is where most of its electricity goes. Better insulation means less loss and fewer reheats, which compounds over a decade of daily use.
2) Is 15 litres the right size?
It is the family size — enough for two showers in succession or one longer one. A 10 litre tank generally covers one person. For a bathroom in continuous morning use, 15 litres avoids the last person waiting for a reheat.
3) What does a glass-lined tank do?
It is a fused glass coating over the steel that stops water attacking the metal. It is the standard defence against tank corrosion and keeps the stored water clean — the tank is the part of a geyser that eventually fails, so its lining matters.
4) What are the safety features for?
The thermal cutout disconnects the element if it overheats. The multifunction valve relieves pressure as water expands on heating. On a sealed pressurised tank both are essential, not optional extras.
5) Can I install it myself?
We would strongly advise against it. A water heater is a high-wattage appliance in a wet area, needing an earthed circuit with an ELCB or RCCB and correct plumbing. Use a qualified electrician.
