I hope I don’t have to write all of this again! Do posts often get lost here?
Anyway, the topic was about choosing between a gas condensing boiler or a heat pump for a house with 140m² (1507 sq ft) of living space, 23cm (9 inches) exterior walls and 13cm (5 inches) Unipor interior walls, triple glazing, and photovoltaic panels on both sides of the roof (producing a maximum of 13,000 kWh per year).
It used to be a night storage heater house, and now I want to equip it with radiators and am considering two types of heat generators. A friend has been doing this for over 30 years with a heat pump and radiators. He says he maintains 25°C (77°F) in winter on 400m² (4,306 sq ft) and has costs of around €1,200.

What kind of custom-made items are those?Well, as far as I know, Unipor produces cellular bricks. I am not aware of any brick format that would allow for a 13cm (5 inches) wall thickness. Are 23cm (9 inches) exterior walls supposed to consist of 15cm (6 inches) calcium silicate brick and 8cm (3 inches) external thermal insulation composite system (ETICS), or how should this be understood?

In any case, €1200 electricity costs for that area, the age of the building (only 10 cm (4 inches) insulation), 25 degrees, and using radiators is not realistic.
That corresponds to about 4,500 kWh electricity consumption.
Check the heat pump consumption database. There you will find real figures – usually for new buildings (extract for 2019 and areas larger than 200 m² (2153 sq ft) below / some consumption is extremely low if the system was only put into operation during 2019). The

Well, as far as I know, Unipor produces porous bricks. I’m not aware of any brick size that would allow for a 13 cm (5 inch) wall thickness. So for 23 cm (9 inch) exterior walls, is it supposed to be 15 cm (6 inch) sand-lime brick and 8 cm (3 inch) external insulation, or how should that be understood? Okay, let’s put it this way... the plan specifies Unipor, and I thought those were Hebel blocks, but in any case, they are aerated concrete blocks or gas concrete blocks.
