You can charge the tank as many times as you like. JP Walther can offer tanks for technology rooms with volumes of about 500 liters and tanks for the laundry room that measure 60x60 cm to fit in a closet space. There are thoughts for most needs. Being able to combine a water jacketed fireplace with an existing or a new heat pump makes you less electricity dependent. With a stove from JP Walther, you can get as much as 70% of the heat to fill the accumulator tank with. This means that you can fire longer without it getting too hot indoors and that you can use this stored heat the next day when you are not at home. A nice way to save electricity. This solution is installed at several retailers and in JP Walther´'s exhibition. Read more about which water-jacketed fireplaces are available to find just the solution that suits you.
