WHAT OUTPUT A PELLET BOILER NEEDS
The output of a pellet boiler is chosen starting from the volume of the home to be heated, measured in cubic meters, and not from the number in the model name. Klover pellet boilers declare a rated heat output between 19.1 kW and 32.4 kW, a heating volume between 470 m³ and 820 m³ and an efficiency between 92.5% and 92.8%.
On the technical sheets of Klover pellet boilers the heating volume is given in cubic meters, because it also takes the height of the rooms into account. The volume of the home is calculated by multiplying the floor area to be heated by the interior height: with the same insulation, a home with high ceilings needs more output than a home with the same floor area and low ceilings.
The range includes two lines. The six ECOMPACT pellet boilers, from ECOMPACT 20 to ECOMPACT 35, have a compact body and the connections on the top. DIVA 26 and DIVA 32 are pellet boilers clad in wood, natural stone or glass, designed to be seen rather than hidden.
The declared heating volume is a reference figure from the technical sheet: it applies to an averagely insulated home, with good quality pellets and a properly designed heating system. The real heat demand depends on insulation, windows and climate zone, and the final output calculation is made by the heating engineer on the data of the home.
HOW MANY KW THE ECOMPACT 20, 23 AND 26 PELLET BOILERS HAVE
ECOMPACT 20 declares 19.1 kW for 470 m³, ECOMPACT 23 declares 22.6 kW for 540 m³ and ECOMPACT 26 declares 25.1 kW for 620 m³. Efficiency is 92.5% on ECOMPACT 20 and 92.6% on ECOMPACT 23 and ECOMPACT 26.
On the ECOMPACT pellet boilers the number in the name does not match the declared output. To compare with the heat demand of the home, the figure to read is the rated heat output on the technical sheet: ECOMPACT 26, for example, declares 25.1 kW.
The ECOMPACT 20, ECOMPACT 23 and ECOMPACT 26 pellet boilers measure 118x57x122 cm and weigh 380 kg. The connections are positioned on the top of the boiler body, a solution the technical sheet describes as a space-saving installation. With the same footprint in the utility room, the choice between ECOMPACT 20, ECOMPACT 23 and ECOMPACT 26 depends only on the heat demand of the home.
ECOMPACT 29, 32 AND 35: THE PELLET BOILER FOR LARGER VOLUMES
ECOMPACT 29 declares 27 kW for 690 m³, ECOMPACT 32 declares 30.5 kW for 750 m³ and ECOMPACT 35 declares 32.4 kW for 820 m³. Efficiency is 92.7% on ECOMPACT 29 and ECOMPACT 32 and 92.8% on ECOMPACT 35.
The three pellet boilers of the upper group have a structure 10 cm taller: they measure 118x57x132 cm and weigh 398 kg. The technical sheet recommends them for demanding heating systems and for large homes. ECOMPACT 29, ECOMPACT 32 and ECOMPACT 35 also share the same dimensions, so moving from one model to another does not change the space to be allowed for.
On all six ECOMPACT pellet boilers heat exchange is increased by 25% and the volume of system water is increased by 20%, for a more immediate thermal response. The advanced thermal insulation of the boiler body holds heat for longer and reduces restarts.
DIVA 26 AND DIVA 32: THE PELLET BOILER ON DISPLAY
DIVA 26 declares 26 kW for 620 m³ with an efficiency of 92.6%. DIVA 32 declares 32 kW for 750 m³ with an efficiency of 92.8%. The two DIVA pellet boilers measure 78x62x133 cm and weigh 380 kg.
The DIVA pellet boilers come in the Blanc Wood, Rovere, Cream Stone, Soap Stone and Black Glass versions. The DIVA 26 sheet recommends it not only for utility rooms but also for living spaces; the DIVA 32 sheet recommends it for substantial homes and large open spaces.
On the DIVA pellet boilers the water connections are on the side, for a space-saving installation and more flexible fitting. Even when the pellet boiler stands in a lived-in room, the choice starts from the same figure: the volume to be heated.
AFTER THE OUTPUT: FLUE, MAINTENANCE AND CONTROLS
All Klover pellet boilers have a 100 mm flue outlet and the A+ energy class. Combustion is sealed and ignition is by quartz, which according to the technical sheets is up to 6 times faster than traditional systems.
Routine maintenance is carried out through the front access points, with intelligent anti-scale self-cleaning that keeps performance steady over time. Active sensors on the parts that open add safety. The controls are on the touch display; Wi-Fi is optional and brings the management of the pellet boiler to the Klover Home App.
