Water pipes

BACKGROUND
In older houses and condominiums, the issue of renovation the water pipes and other plumbing will sooner or later come up for discussion. An alternative to replacing the water pipes is a total reconditioning. This can include the water distributing system and/or a water mediated heating system.
RESULTS

The mean value of increased temperature was 13°C and in some rooms the increase was almost 20 °C. The cost for a successful cleaning is ~10.000 EUR compared to the cost for replacement of the total system, ~100.000 EUR. Furthermore, a cleaning takes ~2 days depending on the size of the house, but replacing the heating system will take a number of weeks, a time quite inconvenient for the people living in the house.

SAVINGS
Om det finns galvaniserade rör i systemet måste en passivisering utföras efter reningen. Gamla rör kan ha sprickor som är täckta av beläggningar. Efter rening kan dessa sprickor börja läcka. Detta beror inte på reningen men rörtester bör göras.
