Advanced all-electric systems now offer remarkable comfort not only in the production of abundant hot water for multiple bathrooms, but also in heating and cooling both in new homes and in major renovations and buildings retrofitted with thermal insulation and photovoltaic systems. All this is achieved primarily using heat pumps: highly efficient appliances that generate up to 4 kW of thermal energy with just 1 kW of electricity. The high efficiency of all-electric appliances allows for the construction of even zero-energy homes and helps builders comply with European regulations that severely limit harmful emissions. Precisely because of their characteristics, these types of appliances are highly sought-after, and the most advanced models offer significant advantages.
