General characteristics
RESIDENCE EXTERNAL
Residence Externa is specifically designed for outdoor installation and stands out for its extremely small dimensions; built with specific materials to operate in absolute reliability even in difficult environmental conditions. Residence Externa is available in powers of 24 and 28 kW.
High-efficiency hot water heat generator for both exposed (Residence Externa) and built-in (Residence IN) outdoor installation, consisting of:
- A wall structure with an open combustion chamber with natural draft.
- atmospheric primary air burner in stainless steel equipped with automatic ignition.
- ionization flame control and proportional regulation system of gas flow and air flow both in heating and DHW.
- CTR system for more rapid achievement of the desired comfort and a reduction in consumption, the formation of limescale in the boiler and temperature changes in the heating bodies.
- Low consumption circulator (IEE 0.20).
- Remote control panel and external probe (optional) allow you to activate the climate control.
- Double exchanger: domestic hot water production with plate exchanger.
- Coating in weather resistant material.
- electrical protection degree IP X5D.
The equipment is completed by:
Antifreeze function (up to -3°C for Residence Externa and up to -5°C for Residence IN): which protects the heating and DHW circuits up to -5°C with the possibility of extending the protection down to -15° C (optional) Antifreeze: when the boiler water temperature drops to around 7°C, the circulator is activated and remains in operation until the temperature rises to around 10°C; if, on the other hand, the temperature drops below 4°C, the burner also switches on at minimum power until, with the boiler in heating mode, the water temperature reaches 30°C; then the burner switches off and after 30” the circulator. Furthermore, when the temperature of the water in the DHW circuit drops to approximately 5°C, the circulator is activated and the burner ignites at minimum power until, with the boiler in DHW function, the temperature of the water in the boiler reaches 55°C; then the burner switches off and after 10” the circulator.
Circulator anti-blocking:
the circulator is activated for one minute approximately 18 hours after the last operating cycle. Three-way valve anti-blocking: the valve is activated to carry out an operating cycle (heating position and return to DHW position) approximately 18 hours after the last intervention .
The new European regulations for heat generators
ErP is the acronym for " Energy related Products " and is the abbreviation that identifies the European Directive ErP 2009/125/EC, defined by the EEC with the intention of reducing energy consumption of products through eco-design (“eco-design”).
The field of action of this European Directive is extremely broad as up to now it has involved products such as light bulbs, air conditioners, washing machines, fans, etc. Following the publication in September 2013 of a series of implementing regulations, starting from 26 September 2015 it will also apply to heating products and the production of domestic hot water.
From the same date, other regulations will also become effective which will implement the energy labeling of the same product families. The transitional period between the publication of the regulations and their activation throughout the territory of the European Community was necessary to allow the full implementation of the contents by companies and market players.
The energy labeling of products for heating and domestic hot water production.
The regulations issued require that all products intended for heating and/or for the production of sanitary water, with a nominal thermal power lower than or equal to 70 kW, are placed on the market with an energy label that highlights their efficiency class.
Note: the regulation provides for the mandatory presence of the energy label for the release of the product from the factories to the market. All products previously introduced, for example present in distribution warehouses, can be regularly marketed even if they do not have an energy label. Various energy labels have been provided based on the use of the generator used: for heating from A++ to G; for the production of domestic hot water from A to G.
A new way to guide the consumer
The purpose of energy labels is to allow the consumer to easily identify the level of efficiency of a product and to be able to make a homogeneous comparison between products that use different technologies. For products whose transformation efficiency is influenced by external conditions, such as heat pump products, as has been done for air conditioners, the efficiency figure is reported for the average climatic range.
In addition to the product energy labels, the European regulations have also provided for the creation of a system label in the event that a plant is created in which various appliances, components and controls operate.
This labelling, thanks to the combinations of the data of the various elements used in the plant, will make it possible to create systems capable of reaching levels of efficiency even higher than those of the individual generators. The European regulation states that the system label must be made available by whoever supplies and/or puts the system into operation (sellers-installers); however, this option is also granted to builders.
