Hello!
We are currently renovating an old building from 1895, consisting of a ground floor, upper floor, and attic, fully basemented, with a total living area of about 330 sqm (3552 sq ft), used as a single-family home for 4 people.
For hot water supply, we have two options:
1. A hot water storage tank in the basement (160 liters (42 gallons))
2. Two instantaneous water heaters (tankless) in two bathrooms, and a small storage unit in the kitchen and guest toilets.
Apart from installation and energy costs:
Is there a significant difference between these two options regarding water pressure or flow rate when showering? In other words, if you want to shower with strong water pressure, is one system clearly better than the other?
Thank you in advance for your answers.

Hello
My recommendation is also to use decentralized domestic hot water preparation. Choose a solar storage tank right away. Insulate the pipes properly (100%) and, for example, use circulation controlled by a push button. The disadvantage of a point-of-use water heater is the low flow rate when filling a bathtub or using a large rainfall shower.
