It is designed for efficient space heating and is suitable for private houses, apartments, townhouses and heating system modernization projects.<\/p>\n<p data-start=\"9153\" data-end=\"9432\">The Bosch GC7700i W 15P has a nominal heating output of 15 kW and a seasonal space heating efficiency of 94%. Thanks to condensing technology, the boiler uses heat from flue gases more efficiently, helping to reduce gas consumption compared with older non-condensing gas boilers.<\/p>\n<p data-start=\"9434\" data-end=\"9742\">This model is not a combi boiler with instant domestic hot water production. For hot water preparation, Bosch GC7700i W 15P can be connected to an external hot water cylinder. This makes it a good choice for homes where a separate cylinder is already installed or where a larger hot water volume is required.<\/p>\n<p data-start=\"9744\" data-end=\"9949\">We provide sales, installation, replacement, connection, setup and maintenance of Bosch gas boilers in Tallinn and Harjumaa. We can also help select a suitable external hot water cylinder, replace an old gas boiler and prepare the system for safe operation.<\/p>\n<h2 data-section-id=\"1sj2pn2\" data-start=\"9951\" data-end=\"9974\">Technical Advantages<\/h2>\n<ul data-start=\"9976\" data-end=\"10525\">\n<li data-section-id=\"10arjja\" data-start=\"9976\" data-end=\"10008\">Model: <strong data-start=\"9985\" data-end=\"10008\">Bosch GC7700i W 15P<\/strong><\/li>\n<li data-section-id=\"yzx2rg\" data-start=\"10009\" data-end=\"10044\">Series: <strong data-start=\"10019\" data-end=\"10044\">Bosch Condens 7700i W<\/strong><\/li>\n<li data-section-id=\"oc9ry\" data-start=\"10045\" data-end=\"10074\">Type: gas condensing boiler<\/li>\n<li data-section-id=\"1io5j9w\" data-start=\"10075\" data-end=\"10103\">Application: space heating<\/li>\n<li data-section-id=\"18bd79j\" data-start=\"10104\" data-end=\"10144\">External hot water cylinder connection<\/li>\n<li data-section-id=\"10kp5yj\" data-start=\"10145\" data-end=\"10180\">Nominal heating output: <strong data-start=\"10171\" data-end=\"10180\">15 kW<\/strong><\/li>\n<li data-section-id=\"fg4z0u\" data-start=\"10181\" data-end=\"10222\">Maximum output at 50\/30 \u00b0C: <strong data-start=\"10211\" data-end=\"10222\">16.1 kW<\/strong><\/li>\n<li data-section-id=\"v532ue\" data-start=\"10223\" data-end=\"10263\">Minimum output at 80\/60 \u00b0C: <strong data-start=\"10253\" data-end=\"10263\">1.9 kW<\/strong><\/li>\n<li data-section-id=\"pu86k9\" data-start=\"10264\" data-end=\"10308\">Seasonal space heating efficiency: <strong data-start=\"10301\" data-end=\"10308\">94%<\/strong><\/li>\n<li data-section-id=\"3p0e14\" data-start=\"10309\" data-end=\"10341\">Energy efficiency class: <strong data-start=\"10336\" data-end=\"10341\">A<\/strong><\/li>\n<li data-section-id=\"1sr9xmn\" data-start=\"10342\" data-end=\"10372\">Sound power level: <strong data-start=\"10363\" data-end=\"10372\">45 dB<\/strong><\/li>\n<li data-section-id=\"1cg74cm\" data-start=\"10373\" data-end=\"10396\">Net weight: <strong data-start=\"10387\" data-end=\"10396\">43 kg<\/strong><\/li>\n<li data-section-id=\"1kalcyg\" data-start=\"10397\" data-end=\"10427\">Product code: <strong data-start=\"10413\" data-end=\"10427\">7736902882<\/strong><\/li>\n<li data-section-id=\"1ds069v\" data-start=\"10428\" data-end=\"10455\">Wall-mounted installation<\/li>\n<li data-section-id=\"sedkn8\" data-start=\"10456\" data-end=\"10485\">Bosch HMI700 control system<\/li>\n<li data-section-id=\"7hlhpn\" data-start=\"10486\" data-end=\"10525\">Ready for Bosch K30RF wireless module<\/li>\n<\/ul>\n<hr \/>\n<h2 data-section-id=\"1hryhf7\" data-start=\"10916\" data-end=\"10922\">FAQ<\/h2>\n<p data-start=\"10924\" data-end=\"11052\"><strong data-start=\"10924\" data-end=\"10971\">What type of boiler is Bosch GC7700i W 15P?<\/strong><br data-start=\"10971\" data-end=\"10974\" \/>Bosch GC7700i W 15P is a wall-mounted gas condensing boiler for space heating.<\/p>\n<p data-start=\"11054\" data-end=\"11225\"><strong data-start=\"11054\" data-end=\"11109\">Does Bosch GC7700i W 15P produce instant hot water?<\/strong><br data-start=\"11109\" data-end=\"11112\" \/>No. It is not an instant combi boiler.
