Energy-conscious use of water
Energy-conscious use of water can reduce your bills consid-
erably. For example, taking a shower instead of a bath:
whereas about 150 litres of water are required for a bath, a
modern shower equipped with water-saving fittings only
requires a third of this water quantity.
By the way: A dripping water tap wastes up to 2000 litres
of water and a leaking toilet flush wastes up to 4000 litres
of water each year.
Run circulation pumps only if needed
(VU only)
Circulation pumps increase convenience when it comes to
hot water production. But they also need power. And circu-
lating hot water that is not used cools off when passing
through pipes and then needs to be reheated.
> Operate circulation pumps only when hot water is actu-
ally needed for the household.
> Use a weather compensator or autotimers to set time
programmes for your circulation pump.
> Or turn on the circulation only for specific needs for a
specific period of time by using a button or switch
installed near a frequently used draw-off point.
> For more information, consult your competent person.
