How can you reduce your electricity, heating, and cooling costs at home to zero?
Amid the continuously rising cost of electricity and natural gas, energy saving has become more relevant than ever. For this reason, more and more investors are turning to renewable energy sources and exploring ways to make them even more beneficial and efficient for their needs.
In this context, NanoDomi, with years of expertise and experience in the field of renewable energy sources (RES), recommends the combination of a heat pump with a photovoltaic installation (net metering).
How does a heat pump work?
Heat pumps work by absorbing energy either from the air temperature (air-to-water heat pumps) or from the ground (geothermal heat pumps) and delivering it to the user in an amplified form. They operate on the same principle as a household refrigerator or an air conditioner. The main difference is that around 75% of the energy required for a heat pump’s operation is “freely” extracted from the environment. Only the remaining 25% comes from electricity consumption.
How does net metering work?
Photovoltaic systems installed under net metering are connected to the public grid. The electricity they produce is used to meet the needs of the property, and in the case of surplus energy, it is fed into the energy provider’s grid and later offset.
The offset is based on energy (kWh). At the end of each billing period, the amount owed to the utility is equal to the value of the kilowatt-hours resulting from the difference between the energy produced and the energy consumed.
If the difference is zero, then there is no charge for the electricity consumed.
How are a heat pump and a photovoltaic (PV) system combined?
Based on the above, the energy savings in each case become clear. However, when a heat pump is combined with net metering, the goal of reducing or even eliminating the cost of electricity, heating, and cooling becomes achievable.
This is because a heat pump can replace energy-intensive devices such as air conditioners or significantly reduce their consumption, as it takes over their thermal load. At the same time, with net metering, it is possible to cover the electricity needs of other household appliances that the heat pump cannot support, while also supplying energy to the heat pump itself.
In this way, all devices benefit either directly or indirectly from the net metering system. This includes the heat pump, since the 25% of electricity it requires for operation is also covered through net metering.
As a result, this combination can lead to a significant reduction or even complete elimination of electricity consumption costs, and therefore to minimal or zero bills to the utility provider.
Based on all the above, it becomes clear that the combination of a heat pump with self-generation photovoltaic systems (net metering) offers the possibility of achieving free electricity and heating indefinitely.
Through highly competitive pricing, NanoDomi has prepared packages combining photovoltaic systems with heat pumps, giving you the opportunity to eliminate fixed energy expenses with a relatively small investment.
