Water-to-water (or "hydrothermal") heat pumps for "sustainable heating": sustainability is in fact at hand if correct and informed choices are made. To do this, it is good to investigate the innovations that improve the sector and among them are the TEON water-to-water heat pumps. Courageous, because they face the main defendant of urban pollution, showing that "it is not true that" and above all, that "it will not always be like this". Let's see why.
Heating and pollution
For some time now, the contribution of traffic to pollution has been decreasing, as has that of industry. On the contrary, the heating of our homes, schools and offices has an inexorably growing contribution. And it will continue to be so as long as we burn fuels to warm ourselves (a practice that dates back to the Paleolithic!), Despite the recoveries of technological efficiency (more touted than real) or switches to methane. But let's try for a moment to consider the idea of not burning to warm up and therefore not emitting pollutants; like? By replacing boilers with heat pumps, that is, with “Objects” more efficient than boilers, and especially cleaner because, in addition to use renewable non-emissive resources (unlike, for example, biomass) they eliminate all pollutants on site.
If starting from now more people choose heat pumps, then we would not have phenomena like those observed and perhaps no one would prevent us - given the ineffectiveness and contingency of the remedy - from using the car in the city in a few days of the year.
The numbers speak for themselves: in terms of PM10, heating contributes on average about 43% to primary particulate emissions in the city and has increased by 47% since 2000. Over the same period, industry and road transport have reduced their emissions by 63% and 50% respectively.
Hydrothermal heat pumps (water-water heat pumps): what it is
The heat pumps (PdC) they extract and transfer energy from resources found in nature to rooms to be heated in winter and cooled in summer. The "transfer" occurs through the "drive torque" of the compressors, powered by electricity. The technologies available are distinguished, among others, according to the source from which to subtract heat (or cold in the case of summer air conditioning). The principle is more familiar than we think: the refrigerator, for example, is a heat pump that extracts heat from the food placed inside it, to expel it through the coil located in its rear part.
Until now, the constraint on the expansion of PdC it was due - in addition to a widespread lack of knowledge of the object and little sensitivity to the subject - to the maximum temperature they could reach, which limited its use to low temperature systems. But innovation has done its job, and today the solutions developed by TEON can also be adopted in existing buildings, on average old or historic, which house radiator systems, and which are heated exclusively by boilers: and this without having to resort to costly terminal replacement interventions.
And here the heating sector can also start that green proposal that we have seen take off in the production of electricity and sustainable mobility.
Why the Hydrothermal heat pumps are they more efficient than a boiler? Soon said. To provide 100 units of thermal energy in an environment to be heated, the boiler must burn on average "120 units" of chemical energy of the fossil fuel or biomass while heat pumps use no more than “30 units” of electricity - the rest comes from the water. To deliver 30 units of electricity to the building, the Italian power plant fleet today consumes (away from home, it should be remembered) approx. 38 chemical energy units of fossil fuel (o primary energy): two thirds less. And if the electricity needed to operate the HP is produced on site, for example with a photovoltaic system, then the question is closed.
Teon's water-water heat pumps: TINA and RETINA
TINA and RETINA (the reversible version for summer cooling) are hydrothermal heat pumps for central heating: that is, they use water (groundwater or other available water resources) from which they take energy to deliver it to the room to be air-conditioned. They use new generation natural refrigerant (and not the F-GAS banned by European and Italian legislation, although still very common) to deliver 100% of the thermal power at 80 ÷ 85 ° C.
This does not make it necessary to renovate the existing system and allows periodic anti-legionella cycles (essential in promiscuity contexts such as schools, hospitals, hotels), without the aid of electrical resistances.
Water-to-water heat pumps: benefits
In addition to the elimination of pollutants in the place where you live, which we have already spoken about, TINA is RETINA they reduce the energy bill up to 60%, as well as the maintenance costs are reduced to a minimum. The use of a renewable source to heat an environment determines the requalification of the energy class and enhancement of the property. Added to this is access to tax deductions (65%) and to the Thermal Account incentives.
If we then consider the reduction in the purchase of primary energy (fuel) at the system level, we also make a contribution to the trade balance of our country.
Not only centralized: MICROTINA and MINITINA
For those who live in villas or in condominiums with two or three floors, and need heating or domestic hot water (perhaps even cooling if there are fan coils) TEON has developed pumps with the same performance characteristics, but more refined in aesthetics: MICROTINA and MINITINA. And with the savings - up to 60% - and the deduction (65%), you pay for the investment.
If we're undecided between the two, here's how they differ. MICROTINA is the smallest of the family, has a variable thermal power from 9kW to 17kW, and absorbs approx. 3kW of electrical power. MINITINA it has a variable thermal power from 31kW to 60kW and absorbs approximately 11kW of electrical power.
