The only alternative here is a storage facility that can be buried in the ground.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">THE SOLUTION<\/h3>\n\n\n\n<p>With the T 300, Haase offers a buffer storage that can be retrofitted to any heating system without taking up additional space in the house. With the standard sizes and equipment, there are already many options for effectively integrating the storage tank into the heating system. In addition, special solutions in terms of size and equipment are also possible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\">THE ADVANTAGES&nbsp;<br>OF THE HAASE UNDERGROUND HOT WATER TANK<\/h3>\n\n\n\n<div class=\"wp-block-columns has-2-columns is-layout-flex wp-container-core-columns-is-layout-2 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div id=\"featurelist-block_f5e42e4a9ed44838711bd5c55cd5c2e2\" class=\" multiple-columns\">\n\n\t\n\t\t<ul class=\"features\">\n\n\t\t\t\t\t\t\t<li class=\"feature-item\">\n\t\t\t\t\t<p class=\"feature-item--title\">Solves your space problems<\/p>\n\t\t\t\t\t\t\t\t\t\t\t<p class=\"feature-item--text\">because the hot water tank is built into the earth.

The possible volume is between 1,900 liters and 14,300 liters.<br>The tank consists of a steel pressure vessel, which is insulated with 100 mm thick polyurethane foam all around. This insulation is protected against the presence of rain or ground water by a cover made of glass fiber reinforced plastic (GRP). GRP is dimensionally stable, age and temperature resistant and 100% corrosion-free and therefore ideally suited for protecting the heat accumulator. If the groundwater level is high, the T 300 underground hot water tank can be equipped with cost-effective buoyancy protection.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-columns has-2-columns
