This system distributes hot water from heating plants to houses and apartments through underground water pipes, meaning that heating sources are centralised, rather than individual houses or apartments having their own heating source. If you're renting and you pay varmhyra - rent with heating included - then you won't save money directly, but heating your home wisely could make it less likely for your landlord to raise your rent to cover increased heating costs. Turning your heating down a couple of degrees can make a big difference to your heating costs, but you can also save money on heating and make your property feel warmer by making it more energy effective.
