It is suitable for private houses, townhouses, larger apartments and properties where a modern and efficient gas boiler of around 30 kW is required.<\/p>\n<p class=\"isSelectedEnd\">The Bosch GC9800iW 30P is not an instant combi boiler. For domestic hot water production, the boiler is connected to an external hot water cylinder. This solution is suitable for properties where a separate hot water volume and stable heating system operation are required.<\/p>\n<p class=\"isSelectedEnd\">The boiler has a nominal heating output of 30 kW and high seasonal space heating efficiency. The modulation range of up to 1:10 helps the boiler adapt to actual heat demand and operate more efficiently during the heating season.<\/p>\n<p class=\"isSelectedEnd\">Condensing technology allows the boiler to use heat from flue gases more efficiently, helping to reduce gas consumption compared with older non-condensing gas boilers. Bosch GC9800iW 30P is suitable for replacing older gas boilers, modernizing heating systems and creating a modern heating solution with an external domestic hot water cylinder.<\/p>\n<p class=\"isSelectedEnd\">The Bosch Condens 9800i W series features modern design, Bosch UI 800 control and connection options through Bosch K30 RF or K40 RF modules. This makes boiler operation more convenient and modern.<\/p>\n<p class=\"isSelectedEnd\">Before installing Bosch GC9800iW 30P, the gas connection, flue system, ventilation, condensate drain, heating system, water pressure and safety requirements must be checked.<\/p>\n<p class=\"isSelectedEnd\">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<p class=\"isSelectedEnd\">Technical Advantages:<\/p>\n<ul data-spread=\"false\">\n<li>Model: Bosch GC9800iW 30P<\/li>\n<li>Full designation: Bosch Condens 9800i W GC9800iW 30 P 23<\/li>\n<li>Series: Bosch Condens 9800i W<\/li>\n<li>Product code: 7736702499<\/li>\n<li>Type: gas condensing boiler<\/li>\n<li>Version: heating boiler with external cylinder connection<\/li>\n<li>Application: heating + external domestic hot water cylinder<\/li>\n<li>Domestic hot water: through external cylinder<\/li>\n<li>Instant domestic hot water: no<\/li>\n<li>Nominal heating output: 30 kW<\/li>\n<li>Maximum heating output: around 30.2 kW<\/li>\n<li>Minimum heating output: around 3.0 kW<\/li>\n<li>Cylinder heating output: around 30.2 kW<\/li>\n<li>Seasonal space heating efficiency: 94%<\/li>\n<li>Heating energy efficiency class: A<\/li>\n<li>Annual energy consumption: 61 GJ<\/li>\n<li>Sound power level: 50 dB<\/li>\n<li>Modulation range up to 1:10<\/li>\n<li>Bosch UI 800 control system<\/li>\n<li>Bosch K30 RF \/ K40 RF module connection option<\/li>\n<li>Hybrid-ready system capability<\/li>\n<li>Suitable for up to 20% hydrogen blend<\/li>\n<li>Flue connection: 80\/125 mm<\/li>\n<li>Wall-mounted installation<\/li>\n<li>Suitable for replacing older gas boilers<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">FAQ:<br \/>\nQuestion: What type of boiler is Bosch GC9800iW 30P?<br \/>\nAnswer: Bosch GC9800iW 30P is a wall-mounted gas condensing boiler for space heating and external hot water cylinder connection.<\/p>\n<p class=\"isSelectedEnd\">Question: Does Bosch GC9800iW 30P produce instant hot water?<br \/>\nAnswer: No. The P version is not an instant combi boiler.
