Hello everyone,
We are about to decide which offer to choose from the heating installer!
As always, the quotes and sizing vary widely!!!
A few facts:
Annual primary energy demand targeted at 42.5 kWh/m²a (according to the latest calculation), which is 31.5% better than a new build.
The house will have about 240 m² (2,583 ft²) of heated space, including bedrooms, dressing rooms, hallways, and a basement party room (which will only be fully heated at certain times), so not all areas will be heated equally. In addition to the 240 m² (2,583 ft²), there are about 60 m² (646 ft²) of basement space.
Currently, 2 people are planned to live in the house, but up to 4 people maximum are expected 🙂
The most attractive offer is for a Vaillant flexoCOMPAKT VWF 88/4 with 8.9 kW, a 185 L (49 gallons) domestic hot water tank, and a 50 L (13 gallons) buffer tank.
On the other hand, I received an offer for a Buderus system with over 13 kW, a 390 L (103 gallons) hot water tank, and a 300 L (79 gallons) buffer tank.
We have a “normal” showering habit and rarely take baths, so very large amounts of very hot water are unlikely.
Every opinion counts, the order is to be placed on Friday.

We have a 160-liter (42-gallon) hot water tank for our house, and my wife also enjoys taking baths. So far, the water has never run cold. However, if you want to install solar panels or something similar on the roof, you should consider choosing at least a 300-liter (79-gallon) tank.
A 160-liter (42-gallon) tank is more than enough for showers for four people. A larger tank is mainly necessary if you have specific cases where a lot of hot water is needed at the same time (for example, a giant bathtub). It doesn’t matter whether you use it often or rarely— even if it’s just at Christmas, the bathtub should be able to fill up with warm water. Otherwise, it’s a one-time use, and the expensive large bathtub just takes up space.

Hello .... maybe let's get back to the topic and avoid private conversations here .... Bad mood?
One thing leads to another; the discussion can certainly drift a bit; after all, we are not on a military parade ground 😉
Best regards, Bauexperte
