Good evening, i am looking for higher output system for community center

below are reply for the guide question:

1. landed or condo? landed community center

2. how many pax in your household? about 200-500 depends on occassion

3. got senior / babies / people with disease like kidney failure for example in the house? yes

4. can you able to do some small DIY installing yourself or not? (like replacement filter yourself?) yes

5. how much u afford to installment per month for at least 5 years? 50/mth or 100/mth or 150/mth?
6. or do u prefer 1-time off purchase? below 1k or 2k or 3k?
Prefer 1 time purchase, budget to be determined still looking for options

7. do you own external water filter yet? no

8. hot/water function is it a must for you? will you willing to fork out another RM50/mth electricity bill for the feature? or you just stick with thermal pot + fridge cold water? only need normal room temperature water no need hot/cold

actually we just need to provide normal drinking water, instead of ordering 5 gallons bottle every time, mainly for events like charity or community activity.

Apology if this is the wrong section, since this is not exactly a home requirements.

Thanks in advance.
