Heating: the new generation appliances
They are beautiful, compact, efficient and connected : the new heat generators - gas or oil boilers, hybrid heat pumps or not - have more to offer than those of previous generations.
Constrained by successive regulations imposed by Europe In the context of the reduction of pollutant emissions, industrialists heating continue to improve the performance of heat generators. Already, low temperature boilers are no longer relevant, rejected by the regulatory requirements for the benefit of condensing boilers, which emit less nitrogen oxides (NOx). The latest models still marketed, said "B1", and installed in collective buildings, will no longer be permitted from September 2018.

Mixed boiler of 24 kW. Power modulation from 9.5 to 24 kW. Hot water flow 11.5 l / min. "Acléis".
Boilers and heat pumps: together or separate, models for the future
Compact gas wall-mounted boiler for heating alone or heating and hot water by micro-accumulation or 100 or 150 l flask. White or black facade, modulation from 10 to 100%. Remote control. "Condens 8300i" and "Condens 8700i".
In addition to improving yields and pollutant emissions, industrial at the same time boiler dimensions, especially murals, and improve aesthetics to facilitate their integration into the living space. However, more than classic boiler, the generator of the future is, according to the specialists, the boiler called "hybrid". It combines the energy adding to oil, natural gas or propane, renewable energy, usually a hybrid heat pump (PAC) or solar, or, recently, micro-cogeneration (Viessmann). This one provides someelectricity at the price of gas, while ensuring the production of heating and domestic hot water.

COP 4.4. PAC air-water with external unit "Inverter" (modulation of the power of the compressor). Management of 2 independent heating circuits and hot water of a 300 l. Can be associated with a boiler. Remote control. "Teamao".
Unlike a heat pump installed next to the existing boiler to take over, the boiler or hybrid PAC integrates a regulator optimizing the separate or simultaneous operation of one and the other, depending on energy (yield), environmental (pollutant emission) or economic (price of each energy) criteria. Both of them generators work separately or simultaneously according to these different criteria ... Thus, the CAP is cut off when the external conditions cause a higher energy consumption than the boiler or when its efficiency generates a cost per kWh of heat higher than that obtained with the boiler. Thanks to this flexible regulation system, the boiler or hybrid HP improves, compared to a single boiler, the annual operating cost of heating.

Other PACs that have proven themselves, drawing on natural energies
PAC air-water, to be installed in new or existing boiler relief, compatible floor heating and radiators, on 2 separate heating zones. DHW preparation 180 l. Refreshing mode. "Lizea lv2000".
In 4, 6 and 8 kW of power, the air-water heat pump "Altherma" evolves technologically, operating up to - 25 ° C outside, ensuring the production of domestic hot water all the year, as well as the cooling the summer.
The Air-water PACwhich dominates the french market, is ideal in replacing a boiler, especially in houses equipped with a heating floor. It is indeed more powerful than it works at low temperatures. The Air-to-air or air conditioner is recommended in heated housing in all-electric, replacing convectors. When it is reversible, it ensures the summer air conditioner equipped rooms. A model says "Multisplit" can power two to five indoor units. However, beware of periods of extreme cold, likely to significantly increase the heating bill. Extra energy is needed. The Geothermal heat pump has the advantage of drawing the calories into the Earth, using a vertical probe or horizontal sensors. Its advantage: its temperature is much more stable than outdoor air; that's why this CAP is more efficient than air-water models. She does so without extra energy, which allows to amortize the additional cost related to the installation of sensors or the vertical probe.

Between connectivity and regulation, on-page heating generators
Intelligent, the "Easy Control CT 200" regulation detects the inhabitants' rhythm of life and anticipates their needs. She even uses the smartphone's GPS to measure distance from home! Expected savings: up to 25%.
With connectivity, the regulation of heating generators no longer obeys only the room thermostat and / or the regulator on the outside temperaturebut to the inhabitants of the house, via a smartphone or computer. With a boiler existing, it is possible to make important energy savings by installing a connected thermostat connected to the thermostatic valves of the radiators. The latter, for this to work, must incorporate a head or control with an electric motor (intended to ensure a rapid reaction) and a room temperature sensor. Linked to a programmable thermostat of the same brand - they must speak the same language - they allow the control and programming room by room of the heating. When this thermostat is connected, we can give him some remote orders, without even taking into account the boiler which, she adapts according to the temperature return water from the heating.

Gas condensing boiler ultra-compact (40 cm wide) and connected, yield up to 109.7%. For new and renovation. "Mira C Green Link".
The "Smart TC" room thermostat is connected to different models of the De Dietrich boiler, allowing remote control of the heating and DHW.
If the boiler is new, the connectivity can be a connection between the boiler and a housing that gets in touch with the family internet box via Wi-Fi. An application on the smartphone allows to control consumption, change the ambient temperatures, start or shut down the heating system, etc. This type of solution is proposed by the boiler manufacturerbut is not open to the control of other objects. However, some industrial heating have partnered to allow it - for example Atlantic, Somfy, Velux, Sauter... -, so that their connected objects speaking the same language can be controlled by the same application, via the same housing.

Quick, we replace his old oil boiler, soon obsolete
Oil condensing boiler, connectable to a heat pump, solar panels or an external balloon, for a more flexible use. Remote control via a smartphone or tablet. "A2".
The oil is no longer in the small papers of the public authorities. However, replace old boiler a more efficient model still gives the right to state aid. The boilers so-called "very high energy performance" allow to benefit from Cite (15%) in certain terms. The boilers "high energy performance" whose expenses will be paid before 31 December benefit from this 15% rate, provided that the estimate was accepted and a deposit paid before 1 January 2018. In addition, the modest households who replace a fuel oil boiler with a generator using the renewable energies are also entitled to a bonus (see Anah).
