Underfloor Heating via Heat Pump
Floor heating is an excellent partner for air source heat pumps. The efficiency of the air source heat pump increases as the required flow temperature decreases. In short, this means that the lower the cooler you can run the system, the lower the operating cost.If designed and installed properly, floor heating can operate at very low temperatures. This makes floor heating and air source heat pumps a perfect combination for ordinary households.
Advantages of floor heating:
Unlike other heating methods, underfloor radiant heating encourages heat to rise through convection instead of forcing it to fall. Floor heating can be in the form of hydraulic heating or resistance heating. We will focus on the first one.
Hydraulic heating involves laying a network of pipes on the subfloor and circulating heating fluid through the pipes. The heated fluid radiates heat to your floor, allowing your home to heat evenly and comfortably. The silent operation of the hydraulic heating is another advantage.
Floor heating heating method:
Fluids can be heated in many ways: using heat pumps, using fossil fuels, or using electricity through boiler heating devices. The heat pump produces hot water at about 40 oC, which is ideal for heating floors. On the other hand, gas and oil boilers heat water to 65-85 oC, which can burn your feet. Using these systems requires mixing hot and cold water to lower the temperature to a comfortable level, which is very inefficient.
The air-to-water heat pump absorbs heat from the environment/outside air and transfers the heat to the water through the heat exchanger in the cylinder. Some heat pump systems can be configured to provide part of the energy required for domestic water heating.
By integrating the heat pump, your floor heating system will have the potential of zone control. This means that the room can be heated on demand, helping you reduce energy consumption. In addition, the heat pump provides the versatility of switching between heating and cooling modes to achieve year-round comfort.
When the target temperature is reached, the heat pump usually uses less energy to maintain heat. Some units can control the temperature as accurately as possible to 0.5 ø C. When there is a large difference between the required temperature and the actual temperature, some heat pumps automatically adjust to a higher frequency to quickly increase the temperature.
Modern heat pump technology also has an intelligent defrost function, which can speed up the recovery speed by reducing the defrosting time and extending the heating time. This further improves the heating efficiency. Since they are designed to work normally in winter, heat pumps usually have built-in antifreeze protection and other protection controls, such as water flow switch protection, compressor overload protection, and high/low pressure protection.
Closing remarks:
By combining heat pump technology with floor heating technology, it will be your wisest choice. You can have the advantages of free design space, powerful heating capacity and no negative impact on health, and you can also enjoy their cost-effectiveness and energy-saving capabilities.
