Choosing a hot-water geyser or electric water heater? Compare 50 litre, 100 litre and 150 litre tank sizes, then compare electric, gas and hybrid geysers. ELIOS offers 100 litre and 150 litre inverter water geysers. Contact the team for a quotation for your city. Both run on electricity and need no gas connection.

Measured electricity use: 2.049 kWh to heat 150 L from 9.9°C to 52.1°C in 55 minutes at 16.4°C ambient temperature. Actual use varies with conditions.
See 150 L electricity use →Choosing a capacity
Choose for your busiest hot-water period. Two homes with the same number of people can need different tank sizes if one has short, spaced-out showers and the other has long showers in quick succession.
A simple example: two back-to-back 8-minute showers at 8 litres per minute use 128 litres of mixed shower water. That does not mean you need a 128 litre tank: stored hot water mixes with cold water, and reheating can contribute during use. Your water temperatures, flow and heating rate determine the tank size.
Consider 50 L when demand is lower and there is time between uses to reheat. Before buying, check whether its usable hot water covers your longest shower and any overlapping tap use. If you regularly run out before the next person showers, compare a larger tank as well as the heating rate. ELIOS does not sell a 50 L model.
Consider 100 L if a 50 L tank cannot cover your peak use and 100 L provides enough reserve with time to reheat. It holds twice the water volume of a 50 L tank; that is not a promise of twice as many showers. Check the measured heating cycles and site requirements before choosing.
View 100 L details →Consider 150 L when closely spaced showers or overlapping hot-water use need more reserve than 100 L can provide. It stores 50% more water than the 100 L model. Confirm that the extra capacity, heating time and installation space suit your routine.

In Pakistan, “electric geyser” usually means resistance heating, “gas geyser” uses a burner, and “hybrid geyser” commonly means a unit that can use gas or an electric element. ELIOS is an electric inverter water heater. Its outdoor unit moves heat from the air into the water, with no gas burner or gas connection.

It runs on electricity, but it is different from an ordinary resistance electric geyser. A compressor and outdoor unit move heat from ambient air into the water instead of producing all heat in an electric element.
Yes. ELIOS offers 100 L and 150 L inverter water geyser models. Contact the team for a quotation for your city and site.
Start with the showers and taps used during your busiest period, their flow and duration, and the time available for reheating. A 50 L tank may suit lower demand spread through the day. Consider 100 L when that storage is too small, or 150 L when you need a larger reserve for closely spaced use. Tank litres are not the same as litres of mixed shower water. ELIOS offers 100 L and 150 L models, not a 50 L model; confirm the size against your use and installation space.
Compare the electricity used in kWh for the same amount of water and the same temperature rise, then multiply by your electricity rate per unit. One kWh is one electricity unit. Watts alone do not tell you the cost of a heating cycle. ELIOS product pages give measured heating cycles and their conditions; the geyser comparison page has a running-cost calculator. Daily use also depends on reheating, standing losses and how much hot water you draw.
Yes. ELIOS is based in I-9/2, Islamabad. Contact the team with your location so they can confirm the suitable capacity, site assessment, delivery and installation arrangements.
