This also includes solid reinforced concrete for industrial applications, or homes with floors made out of natural stone flooring.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><br>How long does it take to complete the UFH Installation?<\/h4>\n\n\n\n<p>Most home installations can be achieved in as little as just one day. This is depending on the floor construction and the size of area we are installing the system into.<br>At what depths are the grooves cut into the floor?<br>The JK\u00ae floorgrinder cuts approximately 16 [mm] into the floor construction. The 14 [mm] JK\u00ae flextube pipe is installed directly in to the cut channels thereafter. The ultimate aim is to have the heating pipes flush, or just under the floor surface.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><br>How much dust is created from the machine during the cutting process?<\/h4>\n\n\n\n<p>The JK\u00ae floorgrinder is fitted with HEPA filter technology, and an industrial on-tool extraction (LEV). The installation is therefore virtually dustless.<br>When can I use the underfloor heating system?<br>This differs depending on each flooring product and the drying time of the adhesives used. Generally, the start-up period may begin a few weeks after installation. However, it is important to begin by using the lowest temperature setting and increasing by a couple of degrees per day to ensure the system correctly integrates.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><br>What if I have timber sub-floor construction? Is installation still possible?<\/h4>\n\n\n\n<p>The JK\u00ae fermafloor is the perfect solution for this, whether it be on the ground or upper floors. For more information visit www.JKfermafloor.com.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"wp-block-heading\">How warm will my house get?<\/h4>\n\n\n\n<p>This is a function of your home\u2019s heat losses versus the heating system\u2019s output. The moment the heat output achieves the required demand, the home will be warm. Modern homes will have no problem heating above 20\u00b0C. Older homes generally do not experience any issues, especially if roof insulation and double glazing is present in the property. However, if you are concerned about this, the best thing to do is get a heat loss report done on the property to see how much energy you need to put into the rooms to heat them comfortably. The JK\u00ae system is fully tested and heat performance reports are available.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Will it work with an uninsulated slab?<\/h4>\n\n\n\n<p>The JK\u00ae system accommodates both insulated and uninsulated slabs, including integration with low-energy systems like heat pumps. We have diligently followed industry guidance to quantify energy loss in uninsulated slabs and meet criteria outlined in Part L (UK) of the building regulations. This is crucial not only from an energy perspective but also in terms of CO2 emissions. The embodied energy within the in-situ slab cannot be compensated by the reduction in subsequent savings achieved through the removal and reinstatement of this building element, as per the guidelines set forth in Part L, building regulations, and SAP.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><br>Should I use a JK\u00ae Ecoline manifold with my ASHP\/GSHP?<\/h4>\n\n\n\n<p>JK\u00ae recommend that the heatpump should be allowed to operate on weather compensation and ideally limited to 45\u00b0C. Using a JK\u00ae ecoline manifold with a heat pump to reduce the water temperature would lose the efficiency gained by using a heat pump. We would recommend the JK\u00ae LT manifold for any low temperature heat source.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><br>Can I use wooden floors or LVT with underfloor heating?<\/h4>\n\n\n\n<p>Wood, LVT and other sensitive floor finishes are excellent choices for use with underfloor heating, however, you must make sure to protect them by installing floor temperature sensors. Flooring manufacturing companies have strict stipulations regarding floor-surface temperatures and these must be monitored. Floor temperatures should be limited by electronic means through your control system and not necessarily by controlling the water temperature, as this is inaccurate.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"Is my existing floor construction suitable for a JK\u00ae system?
