Heat pumps for new buildings
Today's new buildings are significantly more energy-efficient than those of decades ago. Modern construction methods and the choice of energy-efficient building materials ensure that houses are built in an energy-efficient and ecological way. The main purpose of an energy-efficient house is to minimise heat loss. Examples of modern energy-saving construction are both low-energy and passive houses. A low-energy house consumes from 15 kWh/m per year2 up to 50 kWh/m2 energy used for heating, plus the energy used to heat domestic hot water. Low-temperature heat pumps, also known as heat pumps for new build, are suitable for this type of building.
Low temperature heating system
Low-temperature heating is heating of buildings with an average up to 45 °C. Such a low heating temperature requires a larger heating surface to cover the heat losses of the building. For low temperature heating underfloor, wall or ceiling heating systems. These systems have the added advantage that they can also be used in summer. for cooling. Heat pumps, currently the most economical, comfortable and environmentally friendly source of heating/cooling, are installed in low-temperature systems.
Heat pump power
Determining the power of a heat pump is very important from two points of view, namely the cost and the coverage of the heat losses of the building. With an oversized heat pump, you may end up with higher heating or cooling costs than you would otherwise have. An undersized heat pump will not provide enough energy to cover the heat losses of the building, or will use an additional heating source (electric heater) too often, which will ultimately lead to higher costs again.
Heat pump design and installation experts have the right tools to calculate the correct output of a heat pump, so it's best to leave it to them to determine the correct output.
Choosing heat pumps for new buildings
You can get an EcoFund grant to invest in a heat pump
Heat pump heating is one of the renewable sources for which the government offers grants and low-cost loans. The installation of a heat pump for central space heating is eligible for grants ECO Fund up to 50 % of the eligible investment costs.
