The CALEFFI BIOMASS® product series has been created specifically to be used in circuits ofsystems with wood solid fuel generators, operating at high temperature with water or glycolsolutions as thermal medium. The materials of the components and their performance takeaccount of the specific system needs in terms of efficiency and safety of the generators andsystems.
Biomass is “the biodegradable fraction of products, waste and residues from biologicalorigin from agriculture (including vegetal and animal substances), forestry and relatedindustries (including fisheries and aquaculture), as well as the biodegradable fraction ofindustrial and municipal waste”. Biomass can be in the form of a solid, liquid or gas.This line of Caleffi products has been specifically designed for wood solidbiomass (solid fuel).
Solid fuel generators can be classified in two macro-categories:1) Boilers: generators “for solid fuels, hand and automatically stoked”, to be installedin specific technical rooms. Heating takes place via a hydraulic connection to theheating system.
2) Residential devices: “residential solid fuels burning appliances with boiler, notexceeding a total nominal heat output of 35 kW”, installed directly inside the dwelling.Hand or automatically stoked. Heating takes place via air and water circulation, witha hydraulic connection to the heating system. Residential devices can be classifiedin three types:- Fireplace heating systems- Thermostoves- Thermocookers
The generators are further divided according to their fuel stoking system:Hand stoking, typically that of log-burning generators, requires an operator to putthe blocks of wood into the generator stoking compartment.
Automatic stoking refers to the last device conveying the fuel (for example pelletsor woodchips) from the storage tank to the combustion chamber.

ANTI-CONDENSATION VALVE
Function
The anti-condensation valve, used in heating systems with a solidfuel generator, automatically regulates at the set value thetemperature of the water returning to the generator. Keeping the boiler at a high temperature prevents condensation ofthe water vapour contained in the flue gas.Condensation produces tarry deposits that, accumulating on themetal surfaces of the flue gas-system water exchanger, causecorrosion, reduce the thermal efficiency of the flue gas-systemwater exchanger and are a source of danger for the flue gaschimney as they are flammable.The anti-condensation valve gives the generator a longer life andensures greater efficiency.

Valve selectionThe valve selection should be made according to the Kv value(corresponding to a specific DN body size) and not only according tothe threaded connections. Given the system flow rate, thecorresponding head losses on the valve should be calculated by usingthe Kv value. The sum of the head losses on the valve and the headlosses of the rest of the system should be compatible with theavailable head of the generator pump.

ANTI-CONDENSATION VALVE
Operating principle
The thermostat, completely immersed in the medium, controls the movement of an obturator that regulates the flows in by-pass and toward thesystem. On starting up the generator, the anti-condensation valve recirculates the flow water so as to bring the generator up to temperature asquickly as possible (1). When the flow temperature Tf exceeds the set of the anti-condensation valve Tset, the valve’s cold port starts openingto produce the mixing Tmix: in this phase the system loading begins (2). When the generator return temperature Tmix is greater than the settingof the anti-condensation valve by approximately 10°C, the by-pass port gets closed and water returns to the generator at the same temperatureof the system return (3 and 4).

Construction details
Single casting and reversibilityThe compact brass single casting, that houses the pump andfunctional components, enables immediate installation of thedevice, either on the right or left of the solid fuel generator,respecting the flow directions as shown. The temperature gaugescan be extracted from the housings and re-inserted in the sameposition on the back side of the unit.
Anti-condensation valveThis device incorporates a thermostatic sensor to control thetemperature of the water returning to the solid fuel generator so asto prevent condensation. The sensor has been specifically realisedto be removed from the valve body for maintenance or replacementif necessary.
Natural circulation clapet valveThe function of this clapet device is to ensurenatural circulation of the medium in the event ofpump stop due to an electric power failure.When the pump is active, the thrust of mediumkeeps the valve closed, forcing the water to flowthrough the anti-condensation thermostaticvalve. If the event of pump stop, when the waterwithin the boiler is at high temperature, a naturalcirculation of the water begins, by-passing the anti-condensationvalve, thus preventing the temperature in the generator fromreaching dangerous high levels. The unit is provided with naturalcirculation valve locked. To activate its function, remove the lockingscrew.
Dirt separatorIn order to carry out continuous dirt separationin the system it is available the 5462 seriesDIRTCAL® dirt separator as accessory.

Operating principle
The thermostat, completely immersed in the medium, controls the movement of an obturator that regulates the flows in by-pass and toward thesystem. On starting up the generator, the recirculation unit recirculates the flow water so as to bring the generator up to temperature as quicklyas possible (1). When the flow temperature Tf exceeds the set of the anti-condensation valve Tset, the unit’s cold port starts opening to producethe mixing Tmix: in this phase the system loading begins (2). When the generator return temperature Tmix is greater than the set of the anti-condensation valve by approximately 10°C, the by-pass port gets closed and water returns to the generator at the same temperature of thesystem return (3).

SOLID FUEL GENERATOR-TO-GAS BOILER CONNECTION KIT
22 ACCREDITED
ISO 9001 No. 0003ISO 9001 FM 21654
The integration kits make it possible to combine solid fuel generators, equipped with domestic water storage or instantaneous heat exchanger,with gas boilers. Depending on the temperature, the domestic water arriving from the solid fuel generator is sent directly to the user or divertedinto the boiler for thermal integration.
265 tech. broch. 01163
SOLARINCAL
Function
The thermostat, by means of the probe positioned on the hot waterflow from the storage or the DHW heat exchanger built-into the solidfuel generator, controls the diverter valve at the kit inlet. Dependingon the temperature setting, the valve diverts the water towards theuser circuit or the boiler circuit, with thermal integration.A thermostatic anti-scald mixing valve, at the kit outlet, constantlycontrols the temperature of the water sent to the user.

A thermostatic diverter valve, at the kit inlet, receives hot watercoming from the storage or the DHW heat exchanger built-into thesolid fuel generator.Depending on the temperature setting, the valve diverts the waterautomatically and in a proportional manner towards the user circuitor the boiler with storage circuit, with thermal integration.The valve modulates the flow rates to optimize the energy containedin the storage or instantaneously produced by the heat exchangerbuilt-into the solid fuel generator and reduces boiler operation timesto a minimum.A thermostatic anti-scald mixing valve, at the kit outlet, constantlycontrols and limits the temperature of the water sent to the user.

Funzione
A thermostatic diverter valve, at the kit inlet, receives hot water comingfrom the storage or the DHW heat exchanger built-into the solid fuelgenerator. Depending on the temperature setting, the valve diverts thewater automatically and proportionally towards the user circuit or theinstantaneous boiler circuit, with thermal integration.The valve modulates the flow rates to optimise the energy contained inthe storage or instantaneously produced by the heat exchanger built-into the solid fuel generator and reduces boiler operation times to aminimum.A specific thermostatic control device limits the boiler inlet temperatureto prevent it being switched on and off too often, which leads to huntingand irregular operation.A thermostatic anti-scald mixing valve, at the kit outlet, constantlycontrols the temperature of the water sent to the user.
