Do you have tap water in the heating system?
Direct from the tap, here in Sweden we have the best drinking water in the world, but to work optimally as a system fluid in a heating/cooling system, it needs to be degassed. Good drinking water contains oxygen, carbon dioxide and a lot of nitrogen. This makes it excellent for drinking but is devastating for your heating system.
The gases in the water settle along the fins in pumps, insulate sections of heat exchangers, create air pockets in radiators and corrode pipes, valves and radiators from the inside. Poor efficiency, cold apartments and damaged system components lead to unhappy tenants, costly call-out fees and expensive maintenance that could easily be avoided.
The solution is TTM NoXygen! A fully automatic vacuum degasser that cost-efficiently ensures the water is always free from gases and gives the performance you are entitled to expect.
