Insulation, ventilation or heating - what gives the best savings?

A calculation:
  • If you reduce your room temperature in winter from 23° to 18°, you will save 30% of your heating energy without incurring any more costs.
  • New windows are the most expensive renovation option: A kilowatt-hour saved in this way costs around 43 pence.
  • It is cheaper to completely re-insulate the walls. If you take a chance on this investment, you will pay 4 pence for each kilowatt-hour saved.
  • The best choice is to change the heating system: With efficient combustion and condensing technology, the price for a kilowatt-hour saved reduces to to less than a penny!

Weishaupt. That's reliability.
