ECOFIRE® MARTA: the evolution of the species
The star of the fire heating world, once again Palazzetti presents a product with cutting-edge technology: ECOFIRE® MARTA, a hermetic, pellet-burning, water-heating stove with a painted steel cladding and metal side panels that produces hot water for radiators and sanitary use. It can be easily fitted into either traditional or the most modern heating systems and can work in synergy with other alternative heating systems (e.g. solar panels) making it possible to heat the entire home with considerable cost savings.
ECOFIRE® MARTA has an innovative polygonal, semi-circular shaped firebox that is almost enclosed by the combustion chamber that nearly completely surrounds the fire. Heat dispersion through glass is limited to a minimum while still allowing a pleasant view of the fire. Moreover, the area that exchanges heat with the water is extended to the utmost degree. Thanks to this innovation, the power directly transmitted to the water is very high (8.45 kW are transmitted directly to the water out of a global thermal power of 10.2kW), compared to the limited quantity of heat dispersed through radiation. In other words, almost all the energy produced is transmitted to the water.
Why are we talking about transmitting heat to the water?
In water-heating products the important value is not global heat efficiency but the heat that is transmitted to the water. A stove with a high global heat production but with a low heat yield to the water transmits most of the heat it produces through radiation (overheating the room it is installed in) while yielding a small amount of heat to the water which is not able to heat all the rooms in the home.
Marta transmits 83% of the heat it produces to the water: its global thermal power is 10.2kW but all of 8.45 kW are transmitted to the water!
It is also distinguished by its PAC (Primary Air Circuit): the air used to clean the glass is pre-heated (because it is made to flow below the brazier) for more efficient cleaning of the glass. At a closer examination, part of the air taken from outdoors is made to pass under the brazier so that it is heated and then conveyed into the doorframe to clean the glass. At this high temperature the air guarantees a better glass cleaning capacity. It is further perfected by a new system in the glass doorframe that injects the air from the top and bottom in a controlled way (patent pending).
The cleaning system for the heat exchangers that keeps them perpetually clear and guarantees utmost efficiency is also innovative, as is the electronic system that controls combustion by adjusting it to the operating or installation conditions. Thanks to these electronics the stove is pre-set to be flexible and adapt to any heating system (outdoor thermostat, ambient probe, boiler loading with coil, boiler loading without coil). The anti-condensation system is also electronically regulated (patent pending).
