Solar preheating
Solar preheating is always worth it. The lower heat requirements in low-energy houses in combination with increasingly efficient solar systems lead to savings of total heating needs of up to 50%. However, even existing systems can be retrofitted to support solar preheating, usually without much effort. That way, a great deal of heating oil or natural gas can be saved.
