Once you know the capacity and Geyser type, you can choose between a vertical vs horizontal geyser. In this guide, we explore the pros and cons of both approaches. At the end, you will get clarity on taking a horizontal vs vertical geyser.
Try to choose the right geyser by answering simple questions without reading any Buying Guide.
Traditionally, Geyser water heaters are vertically mounted. Horizontally mounted geysers are new to the market. For electric instant Geysers come only in a vertical mounting style. There are no horizontal instant geysers in the market.
The reason is that instant geysers take so little space on the wall, and there is no point in changing the mounting style. The stored geysers with at least 15 litres capacity come in two flavours – vertical geysers and horizontal geysers. These are also known as V-Wall geysers and H-Wall geysers. A table with short differences is given below.
| Feature | Vertical Geyser | Horizontal Geyser |
|---|---|---|
| Requirement | Need vertical space | No need of vertical space |
| Price | Cheaper | Costlier |
| Aesthetics | Looks ok | Looks beautiful |
| Energy efficient | Best efficiency in heating | Moderate efficiency in heating |
| Installation | Very easy to install | No need for vertical space |
| Example | Bajaj New Shakti Neo 15L Vertical Geyser | AO Smith HAS-X1-025-RHS Storage 25 Litre Horizontal Geyser |

When to Choose Horizontal Geysers?
Vertical geyser water heaters require at least two feet of vertical length on the wall. If your bathroom ceiling is low, you have decorated with a false ceiling, or have an attic, then you won’t have enough vertical space on the wall to mount the geyser vertically. In this case, horizontal geysers make sense.
Apart from that, horizontal electric geysers aesthetically look very beautiful in the bathroom. While installing a horizontal geyser, make sure there is enough space adjacent to attend to minor repairs. It is a very bad installation if, even for minor repairs, you need to unmount the geyser from the wall. Confirm with the plumber whether they have expertise in installing horizontal electric geysers, as it is little difficult compared to vertical and requires little expertise.

Horizontal Geysers vs Vertical Geysers
If you have sufficient space on the wall, you can choose between horizontal and vertical. The real question is whether I have space to install both types of electric geysers, and then which one to consider.
Traditionally, electric geysers are vertically mounted, and it is a natural method as well. Horizontal geysers are introduced to address space constraints. It is believed that Vertical electric geysers are more efficient. The reason is stratification. Stratification is a measure of the ease of mixing cold and hot water. The explanation is as follows.
Hot water has less density, so it tends to go to the top of the water tank of the geyser. The cold water stays at the bottom. When both waters mix, there is some turbulence and friction when water is pushed out of the geyser. This turbulence is less in the vertical geyser model compared to the horizontal model. So water is dispersed very easily in the vertical model.
Apart from that, vertical models are generally considered energy efficient. This is a general opinion, but few horizontal manufacturers can go beyond and try to achieve efficiency. Pricing is another criterion.
Horizontal electric geysers tend to be costlier than vertical electric geysers. The price difference goes from 20 to 30%. For example, AO Smith 15-liter vertical geysers’ price is around Rs. 7,000, whereas the horizontal ones’ price is around Rs. 9,000. Gas geysers usually do not come in horizontal models.
Bajaj, Havells, Racold, V-Guard, AO Smith, Kenstar, and Crompton are well-known brands with varying capacities like 10 ltr, 15 ltr, and 25 ltr. You can buy these electric geysers online from Amazon and Flipkart.
Frequently Asked Questions ( FAQs ) on Vertical vs Horizontal Geyser
1. Can a Vertical Geyser be Installed Horizontally
A vertical geyser is a water heating device designed to stand upright. It looks like a tall cylinder and helps heat water for homes.
Safety Reasons
- Internal parts are designed for vertical positioning
- Horizontal installation can cause water leakage
- Risk of damaging heating elements
- Potential warranty cancellation
2. Can a Horizontal Geyser be Installed Vertically
A horizontal geyser is a water heating device designed to be mounted sideways. It’s typically wider and flatter compared to vertical models, making it unique in water heating technology.
Why Vertical Installation is Problematic
- Designed specifically for horizontal placement
- Internal components are configured for side-mounting
- Vertical installation disrupts water flow
- Can cause serious functional issues
Potential Risks of Incorrect Installation
- Water distribution complications
- Increased pressure on internal pipes
- Reduced heating efficiency
- Potential complete system failure
- Immediate warranty cancellation
3. Can we install Vertical Geyser horizontally
A vertical geyser is a water heating device designed to stand upright. Its tall, cylindrical shape is specifically engineered for vertical positioning.
Technical Limitations
- Internal components are designed for vertical placement
- Specific water flow mechanisms require upright positioning
- Horizontal installation disrupts the entire heating system
- Risks of damaging critical internal parts
Critical Installation Challenges
- Uneven water distribution
- Reduced heating performance
- Potential water leakage
- Complete system malfunction
- Immediate warranty voiding
