ᐅ Is the hot water storage tank sufficient?

and here comes the next question^^

We currently have a setup with a 180 L (48 gallons) hot water tank. What are your experiences— is this size sufficient, or is a larger one recommended?
Background information:
Ground source heat pump Nibe Fighter 1245 with the 180 L (48 gallons) tank
Currently a household of 2 people (but it may grow in a few years^^)
Mainly showering habits, but there is also a large spacious bathtub
(either 200 L (53 gallons) or maybe even one with 350 L (92 gallons), although I understand that I can’t fill it completely hot with a 180 L (48 gallons) tank ^^)

What do you think about Nibe?

Best regards

Hello,

we have planned a 300-liter (79 gallon) hot water tank, and I wouldn’t recommend going smaller.

I’m not exactly sure what size my parents had, but it was definitely small enough that during Sunday showers with two teenage girls, the hot water ran out quickly.

Please provide the basic data of this design!

Especially for hot water preparation with a heat pump, large heat exchanger surfaces are important. The majority of such complete offers are rather not very "heat pump friendly."

Best regards

Hello €uro,

could you please specify your question and let us know exactly what information you need?

We had also planned for 300 liters, 180 liters seems quite low to me.

Well..

The thing is.. the 180-liter (48-gallon) model is included..
there is also the +300 version available for an extra 1500€, but then we have 480 liters (127 gallons).
