Hello everyone,

We would like to order the components for our heating system soon.
The following information is the basis:
- New detached house built according to legal standards
- Heated living area: 193 m² (2077 sq ft) (floor plans attached)
- Planned heat pump: ground source heat pump Bosch CS 7800iLW 8 F 8 kW
- Planned buffer tank: Stora WH 370 LP1B
- Drilling depth to be determined according to the system
- Designed for a household of 4 people

Questions: Do you consider the 8 kW ground source heat pump sufficient? Is the 350 L (92 gallons) buffer tank adequate? Is a second buffer tank for the heating water necessary?

Thank you very much and best regards

The heating engineer plans to install the heating circuits as close together as possible, so we are aware of that.

I hope he also calculates that properly and doesn't just estimate. Have you discussed the desired room temperatures and the flow temperature with the heating engineer? Focus especially on the bathroom since the floor area is often too small and a wall should also be used.

We have discussed that so far, yes.
We will pay special attention to the bathroom, I will ask again about that. Thanks for the tips.
