Why can the Holland Damp Proof System® lower my heating bills?
Since the Holland Damp Proof System® dries out the walls, they become better insulators, keeping the heat inside the house. By lowering the humidity level of the air in the house, you will feel more comfortable at a lower temperature, which leads to lower heating costs. Less energy is required to warm air with a lower humidity level. (See also: Will the Holland Damp Proof System® make my house colder?).
