Clean energy for free.
There are several solutions able to satisfy every possible need.
Their differences are related to the provided comfort level, architectural compatibility and the economical value both in terms of installation cost and operating cost savings.
Another relevant factor is the different environmental impact associated to the several solutions, or better, the relative greenhouse gas emission saving compared to a traditional heating/cooling system.
All the proposed solutions are applicable to both new and existing buildings; the latter has the extra-benefit of 55% tax detraction on the total cost.
Furnace replacement
It’s the replacement of the traditional furnace with the heat pump, leaving untouched the existing radiant system.
Particularly suggested in those cases where the customer wants to minimize installation time and costs, avoiding any construction work (for example in case of fairly new buildings or buildings recently retrofitted).
In cases where the house already has a low temperature radiating system (for example floor heating) then the furnace replacement with the heat pump guarantees a higher level of comfort and an even more relevant money saving.
In this case is possible to use the geothermal energy for summer cooling as well.
Heat-pump for heating, cooling and hot water
Unlike the previous case, in new building or in case of retrofit the system is designed from scratch to optimize the performances all year long, giving the maximum comfort and a higher economical saving.
The same low temperature radiating system (floor, ceiling or walls) will provide heating during the cold seasons and cooling during hot seasons.
Furthermore, hot water is guaranteed in every moment.
One heat pump fully replaces the three traditional systems.
Integration with solar-thermal panels
It is possible to improve the already excellent system-efficiency by integrating it with solar-thermal panels.
The result will be a further reduction of the fossil fuel consumption (electricity).
Integration with photovoltaic panels
A geothermal system needs electricity to feed the compressor and the electrical pumps used for the fluid motion on the primary and secondary circuits.
The electricity needs can be covered, partially or totally, by photovoltaic panels feeding directly the heat pump or stored in the grid and used later on when needed.
This way it’s possible to reduce or even cancel the operating costs, reaching the complete autonomy of the geothermal system.
Integration with both solar-thermal panels and photovoltaic panels
Achieved by the integration of the two previously described cases, it represents the most advanced solution, able to provide the best comfort, the cheapest operating economy and the energetic auto-sustainability (zero-emission).
