I live in a storey house, got centrailized pump and a common water heater. The pressure is good but flow is not huge as hotel rain showers. Also, water is not hot enough at night. Do I need to install tank-based water heater? also, will I need additional pump after the water heater tank? couldn't find much information on setting up hotel-like rain shower at home.

Also with tank-based heater, if i do not back home for 1 month, it will heat up the water inside everyday?

Thanks.
