I have a 10-litre fish bowl and I recently got home a young betta fish. I’ve read that I these fish like warm temperatures ( 23-27 deg C )…but the water in his bowl gets cold and most of the times is at 21-22 deg C. I tried finding a water-heater for bowls but I couldn’t find one anywhere. What other way can I keep my betta fish a bit more warmer??
First off don’t panic, if the water never goes below 21C your betta will probably survive OK. They are a tropical fish, and 21C counts as "tropical".
See I would never even consider keeping a betta without a heater, but in winter I could have tank temps down to 10C on a cold morning. That wont worry a goldfish, but it’s fatal for betta.
But they are happier in warmer water, up around 25C. They will be more active, healthier and hopefully live longer.
Small tanks and bowls are difficult to heat reliably. I would suggest you leave they fish where it is for now, it not in serious danger, and save up for a bigger aquarium that you can heat and filter properly.

If you are keeping a betta in a fish bowl and are not sure how to keep its water warm, here are some ideas
Get a heating pad, like those used for reptiles
Wrap the fishbowl with fairly thick towels, making sure not to cover up the opening.
3
Consider getting a larger tank. Anything 2.5 gallons or larger can be heated with an aquarium heater.
4
Aim for a temperature of 75-82 degrees F. Anything colder or warmer is bad for your betta’s health.

Use the towels all the time if your fish is really sensitive to cold
I have used the light that came with the tank as a heater which worked quite well. Try keeping the tank or bowl away from the window where temperature changes are more prevalent. Also, if you don’t have a filter for your fish bowl I would consider getting a new one with a filter and a heater if possible.
I have a fish tank that is approximately the same size that you have for your betta. I have successfully kept 3 different bettas in this tank, not at the same time of course! The first two lived for about 4 years each and my current one is two.
No fish can live in a bowl. Bettas need at least 20 litres worth of tank space, along with a filter and a heater. Without this equipment you will soon find yourself the owner of a dull, dying fish.
They sell betta tank sized heaters at Petco/Petsmart, and maybe even your local fish store.
Consider geting a larger tank. Bettas do best in 5+ gallons with a heater AND filter.
