Is it possible to retrofit a masonry stove or does it have to be built directly into the screed?
It can be done afterwards. We are having ours installed/built next year. The screed is needed as a base, but that’s due to the statics. Because they can quickly weigh over a ton.
Are you building new? I would plan it in right away. For us, it’s being installed in a 101-year-old house. In our case, in a load-bearing wall because we have vaults underneath. In a new building, it probably shouldn’t be a problem, but I’m not a structural engineer.
A friend who works at Stiebel Eltron reports similar, the production capacities are absolutely maxed out.
On "Face Buch" I have been observing for a few weeks that there are companies that have ordered heat pumps in stock and now have to get rid of them since there are fewer new buildings. You just must not focus too much on one manufacturer. especially when the house gets cold.
So at least with industrial automation components the situation is slowly improving a little. One no longer generally waits for all components for 1 year or more. Taiwan and China have been rattling their sabers for decades. Taiwan is much, much more important than Ukraine and will be defended by the USA. China knows that. And China is still far from being technologically advanced enough to take on the USA in an open battle in the South China Sea and clearly win the battle.
