1) In two stories terrace house, (first floor 2 bathrooms, g floor 1 bathroom) , 440gallon water tank is on first floor roof, anyone knows how well usually the water pressure be on the first floor? Good enough for rain shower heaters?
2) Someone suggested me to get the heater with pump first, if the pressure is not good then install the main pump but I am afraid I will waste more money because heater with pump is more expensive, once we have main pump there is no point anymore.
3) Are heater with pump less durable compared to those without pumps?
4) What about the electricity? Will the main pump use more electricity compared to heater w/ pump?

1) Usually not good enough due to low headroom.
2) Heater with pump can definitely increase the pressure. But whether it reach your desire pressure or not is another matter.
3) Usually when there is more components, the tendency of breaking down is higher.
4) Yes, it will cost more. But the amount is not significant.

Do you have outdoor filter with sand type or membrane type ?
I read in other thread that sand type may cause low water pressure when using rain shower.
If the water is come from the roof tank, then i has nothing to do with the outdoor filter.I read in other thread that sand type may cause low water pressure when using rain shower.
