Hi,
I am currently planning the modernization of our 29-year-old house.
Apart from recurring renovation work inside the house, no major (modernization) measures have been carried out so far.
We have additionally insulated the walls ourselves in the past.
Nothing else.
That means the house:
- still has the original roof
- the original gas heating system
- the original windows on the ground floor
What is already fixed and will be carried out in late summer/early autumn is the roof modernization according to [KFW] guidelines. That means the roof will be completely rebuilt and insulated.
Additionally, I have budgeted about 13,000 euros for a photovoltaic system.
However, I am still not sure how sensible the installation of a photovoltaic system really is.
The company I am in contact with recommended using the electricity and feeding the rest back into the grid.
My first considerations were actually to have a storage system to be able to use the electricity at night or during bad weather...
The location would be ideal for a photovoltaic system, as our roof faces southeast.
Therefore, I have now thought whether I should rather invest the money in a new heating system.
Our heating system has been in use since the house was built and has never caused any problems.
However, I think that new gas heating systems should work more efficiently and reduce gas consumption (I hope).
In addition, I would probably still have a few euros left over to possibly replace radiators.
Provided radiators can contribute to efficiency...
Maybe you have some advice or would share what you would do.
Regards
