The Duo-tec+ range of boilers is equipped with a digital control panel with backlit LCD display, easy to use thanks to dedicated and independent keys to adjust the temperature of the domestic hot water and the heating. The display allows you to view all the information and set the operating parameters in a clear and immediate way.
The circulation pump can operate at maximum speed, minimum speed or in "automatic" mode: in the latter case, the speed (min./max) will be selected so that the delivery/return ∆T in heating remains constant at 20 °C thus ensuring a significant reduction in pump consumption and, given the lower mechanical stresses (compared to a pump that always runs at maximum speed), also in maintenance costs
Characteristics:
- Wide modulation range up to 1:7 greater efficiency and silence
- GAC (gas adaptive control): automatic combustion control
- High efficiency circulation pump with total modulation
- Digital control panel with large backlit LCD display
- Arrangement for combination with the Baxi integrated solar system
- Ø50 mm exhaust pipe: solution for restoring flues - mod. 24 kW
ErP/EcoDesign – Mandatory labeling from September 2015
Why ErP (Energy related Products)?
To be placed on the EU market, a product must have the brand , or comply with all the European Directives applicable to it.
The Ecodesign and Labeling Directives (eco-design and energy labelling) were created to help the EU achieve the objectives of the EU 20-20-20 Plan, with a particular focus on reducing CO2 emissions by 20%, the increase energy efficiency by 20% and to increase the use of renewable energies by 20%, all by 2020.
For this reason, all heat generators for space heating, appliances for the production of DHW and systems of several of these appliances combined in combination will have to comply with eco-design requirements and be labelled, in accordance with the implementing regulations, for be able to be placed on the market by the producers.
From 26 September 2015 , the directives will affect all products described above with a Pn ≤ 400 kW for eco-design and with a Pn ≤ 70 kW for labeling, intended for markets in all countries of the European Economic Area.
Which directives are affected?
How does the placing on the market take place?
Placing on the market is carried out by the manufacturer (or by the importer from outside the EU) when the product is made available for the first time on the EU market. This happens when ownership changes to a distributor (invoice).
What products can be sold?
All products with the CE mark placed on the market before 01/08 and 26/09 2015 are considered compliant and therefore salable until they run out. All products that will be placed on the market (sold) by the manufacturer/importer after these dates will have to comply with the new standards.
What is a product according to ErP (Ecodesign)?
A luminaire designed to operate at maximum efficiency with minimum environmental impact. To comply with this directive, the product must have Pn ≤ 400 kW and, as regards hot water tanks, a volume ≤ 2000 litres. Manufacturers are obliged to place only ErP-compliant products on the market with these deadlines:
- from 1 August 2015 only products equipped with high efficiency pump
- from 26 September 2015 only products that meet the minimum ErP efficiency requirements
Ecodesign defines the requirements that products must meet in order to be placed on the market, based on:
-
Seasonal efficiency for heating and efficiency for DHW production based on the declared load profile
-
Emissions (NOx values)
-
Maximum permissible noise level of hydronic heat pump outdoor units
What is a Combi product according to ErP?
An appliance (single or with boiler) for heating and DHW production, already equipped with labeling with energy class information relating to a DHW load profile.
What is a load profile in ACS?
For mixed heat generators and DHW producers, the regulations define a certain sequence of water withdrawals as a load profile, essentially a simulation of daily operation of the product, with different withdrawals at established times, flow rates and ∆t . Therefore a product must be able to deliver the declared profile, on which the efficiency in obtaining it will then be calculated, which will determine the class declared on the label. For example:
Examples:
What is the Energy Label?
The labeling directive (2010/30/EU) requires products to be labeled according to a decreasing energy scale ranging from A + + + to G. There is also an energy label for the installed system, depending on the components used ( for example a boiler, DHW tank and room temperature controls). The label was created for the final consumer, providing real and comparable data, to make informed choices and targeting high-efficiency products.
There are energy labels:
