Whether such a modernisation is suitable depends, however, on the building\u2019s heat losses and the water temperature required to heat the rooms. The higher the required flow temperature, the more difficult it becomes to achieve high heat pump efficiency.<\/p><p>When assessing the building, factors such as its floor area, wall and roof insulation, the condition of the windows and the existing heating system are taken into account. The parameters of the current heating installation are equally important. For example, in a home with large radiators, a new heat pump may be able to work with the existing heat distribution system. In another building, some radiators may need to be replaced or the insulation improved. The final decision should be based on calculations of the building\u2019s heating demand rather than solely on previous oil consumption.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6221937 elementor-widget elementor-widget-heading\" data-id=\"6221937\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Does the house need to be insulated before installing a heat pump?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5174488 elementor-widget elementor-widget-text-editor\" data-id=\"5174488\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>A full thermal renovation is not a requirement for installing a heat pump. However, if the building has high heat losses, improving wall or roof insulation or replacing draughty windows can significantly reduce the heating demand. This may make it possible to install a lower-capacity heat pump and reduce its subsequent electricity consumption.<\/p><p>If the owner is planning to insulate the house in the near future, it is best to take this into account before selecting the heat pump. A unit sized for the building\u2019s current heating demand may become oversized once the thermal renovation has been completed. It is therefore worth planning the sequence of work and estimating the home\u2019s heating requirements after the planned improvements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c5e6ab2 e-flex e-con-boxed e-con e-parent\" data-id=\"c5e6ab2\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-cb16290 elementor-widget elementor-widget-image\" data-id=\"cb16290\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/5-4-1024x768.png\" class=\"attachment-large size-large wp-image-21425\" alt=\"5 4\" srcset=\"https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/5-4-1024x768.png 1024w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/5-4-300x225.png 300w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/5-4-768x576.png 768w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/5-4-1536x1152.png 1536w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/5-4-16x12.png 16w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/5-4.png 1600w\" sizes=\"(max-width: 640px) 100vw, 640px\" title=\"\">\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-723aa0b elementor-widget elementor-widget-heading\" data-id=\"723aa0b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"How_should_the_existing_heating_system_be_prepared_for_a_heat_pump\"><\/span>How should the existing heating system be prepared for a heat pump?<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-82398d8 elementor-widget elementor-widget-text-editor\" data-id=\"82398d8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>One of the most important parameters is the flow temperature, meaning the temperature of the water supplied to the radiators or underfloor heating system. In installations with oil boilers, this temperature can be relatively high, while heat pumps operate more efficiently at lower values. It is therefore necessary to check whether the existing radiators will be able to heat the rooms effectively at the operating temperatures planned for the new system.<\/p><p>It is worth remembering that radiator output decreases as the water temperature is reduced. A radiator that heated a room effectively with a flow temperature of 65\u00b0C may provide too little heat at 45\u00b0C. One solution may be to install a larger radiator or a model with a higher heat output. It is not always necessary to replace every radiator \u2013 often only selected rooms require changes.<\/p><p>Pipes, circulation pumps, valves and the domestic hot water system should also be inspected. The installer should assess the condition of these components and then determine what changes are required. In a well-maintained system, the scope of the modernisation may be limited mainly to the boiler room and a few selected elements of the installation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b40e67d elementor-widget elementor-widget-image\" data-id=\"b40e67d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/6-4-1024x768.png\" class=\"attachment-large size-large wp-image-21426\" alt=\"6 4\" srcset=\"https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/6-4-1024x768.png 1024w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/6-4-300x225.png 300w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/6-4-768x576.png 768w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/6-4-1536x1152.png 1536w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/6-4-16x12.png 16w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/6-4.png 1600w\" sizes=\"(max-width: 640px) 100vw, 640px\" title=\"\">\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-067e1c4 elementor-widget elementor-widget-heading\" data-id=\"067e1c4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"How_does_replacing_an_oil_boiler_with_a_heat_pump_work_step_by_step\"><\/span>How does replacing an oil boiler with a heat pump work step by step?<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1a734e0 elementor-widget elementor-widget-text-editor\" data-id=\"1a734e0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>The process begins with a technical assessment and ends with commissioning and adjustment of the new heating system.

This ensures that the correct amount of heat reaches each room without unnecessarily increasing the flow temperature. The heating curve is also configured to determine the water temperature according to outdoor conditions.<\/p><p>Before the system is handed over, the owner should receive instructions on operating the heat pump and adjusting the basic settings. During the first heating season, it is worth monitoring electricity consumption and indoor temperatures. If the system operates too intensively or does not provide sufficient comfort, the settings may need to be adjusted.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c411ff2 elementor-widget elementor-widget-image\" data-id=\"c411ff2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/4-5-1024x768.png\" class=\"attachment-large size-large wp-image-21424\" alt=\"4 5\" srcset=\"https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/4-5-1024x768.png 1024w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/4-5-300x225.png 300w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/4-5-768x576.png 768w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/4-5-1536x1152.png 1536w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/4-5-16x12.png 16w, https:\/\/voltmax.lu\/wp-content\/uploads\/2026\/10\/4-5.png 1600w\" sizes=\"(max-width: 640px) 100vw, 640px\" title=\"\">\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-27cb38f elementor-widget elementor-widget-heading\" data-id=\"27cb38f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"What_should_you_remember_when_replacing_oil_heating_in_Luxembourg\"><\/span>What should you remember when replacing oil heating in Luxembourg?<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d4492de elementor-widget elementor-widget-text-editor\" data-id=\"d4492de\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Before starting the modernisation, it is important to check the formal requirements that apply in the municipality where the building is located. Depending on the type of heat pump and where it is installed, a permit may be required. For air-to-water systems with an outdoor unit, Luxembourg\u2019s requirements concerning noise emissions must also be taken into account. After the heat pump has been commissioned, the contractor is also required to register it under the appropriate inspection procedure.<\/p><p>Luxembourg also offers financial support under Klimabonus 2026, including support for the installation of heat pumps in existing buildings. The programme also provides assistance for adapting the heat distribution system and EUR 1,500 towards the removal, neutralisation and recycling of an oil tank, provided that the relevant conditions are met. In the case of the tank, the work must be confirmed by an invoice issued by a specialised company.<\/p><p>The amount of financial support available depends on the type of investment and whether the programme requirements are met. Before ordering the equipment, it is therefore worth checking the current rules, required documents and applicable deadlines. This makes it possible to take potential subsidies into account when planning the overall cost of the modernisation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e3ca40c elementor-widget elementor-widget-heading\" data-id=\"e3ca40c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"How_can_Voltmax_replace_an_oil_heating_system_with_a_heat_pump\"><\/span>How can Voltmax replace an oil heating system with a heat pump?<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c9bebda elementor-widget elementor-widget-text-editor\" data-id=\"c9bebda\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Are you planning to replace the oil boiler in your home in Luxembourg?
