Hello everyone,

How large are your domestic hot water tanks? We are planning a heat pump system with a separate 300 L (79 gallons) domestic hot water tank. Our installer wants to install a unit with an integrated tank of only 170 L (45 gallons) and says that would be 100% sufficient.

We have two bathrooms, one with a bathtub measuring 180 x 80 cm (71 x 31 inches) plus a rain shower, and the other bathroom has only a shower. Ideally, we will have four people living here eventually: two adults and two children.

What are your experiences, and how large are your domestic hot water tanks? Do you think the smaller tank would be enough?

We are 5 people and also have 300 liters (79 gallons). 170 liters (45 gallons) would not be enough for us.
