This can be done in two ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>through partial decentralisation in summer<\/strong>, by adding a small boiler to heat the domestic hot water. It will allow to shut down the main boiler in summer but will still be connected to the hot water system. Decentralisation can also not be total if the domestic hot water production system is separate, either following the installation of a thermodynamic water cylinder operating at high temperature (advantage of the COP on electricity consumption linked to the production of DHW compared to an electric boiler)<\/li>\n\n\n\n<li><strong>through the installation of a boiler sized to cover the DHW requirement<\/strong>, or the installation of suitable electric boilers with storage capacity to limit power demand peaks.<\/li>\n<\/ul>\n\n\n\n<p>This technology is particularly suitable for hotels with a high demand for domestic hot water. Setting up this new technology will allow the company to save energy, while reducing its carbon footprint. However, implementing this measure can be rather complex with a medium-to-long-term return on investment, and requires the temporary shutdown of production during the technical installation stage.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h3 class=\"type-numerotation\"><span class=\"type-numerotation-span visually-hidden\"><\/span>Energy and environmental impact<\/h3>\n\n\n\n<p>The two joint positive effects are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Energy savings on DHW production because the energy evacuated to the outside is recovered (= waste heat).<\/li>\n\n\n\n<li>There is an environmental gain because final consumption for the DHW production is lower than the initial consumption.<\/li>\n<\/ul>\n\n\n\n<p>The estimated energy savings are around 60% for the domestic hot water production system. This translates into a positive impact on the carbon footprint, particularly if the DHW was initially produced using a fossil fuel (although dependent on the initial energy production method).<\/p>\n\n\n\n<h3 class=\"type-numerotation\"><span class=\"type-numerotation-span visually-hidden\"><\/span>State subsidy application<\/h3>\n\n\n\n<div class=\"wp-block-group has-light-green-background-color has-background\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h4 class=\"wp-block-heading\">State subsidies<\/h4>\n\n\n\n<p><strong>Please note: any application for government or non-government subsidies must comply with the \u201cincentive effect\u201d, subject to compliance with the subsidy conditions.<\/strong><br>To ensure that the \u2018incentive effect\u2019 is respected, no binding commitment (signing a quotation; paying an advance) may be made BEFORE submitting the application file or receiving the agreement in principle from the State or the electricity and natural gas supplier following an application for subsidies.<\/p>\n\n\n\n<p><a href=\"https:\/\/guichet.public.lu\/en\/entreprises\/financement-aides\/regime-sme-packages\/soutien-pme\/sme-packages-sustainability.html\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>SME Packages &#8211; Sustainability<\/strong><\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Financial Aid for small and medium-sized enterprises covering up to 70% of eligible costs for the implementation of a project aimed at reducing the environmental impact.
