KONx SLIM is a condensing boiler running on methane or LPG, with instant production of domestic hot water. Covered with a satin AISI 304 stainless steel casing, it is ideal for outdoor installations, but equally elegant indoors.

KONx SLIM is:

• High performance 24 and 35 kW (Range rated) Modulation ratio 1:8
• Low NOx class 5 High energy efficiency A+ (System) the top of the category, >98% Hs (higher calorific value)
• Insulated and protected IP X5D, suitable for external installation according to current regulations (up to -15°C with antifreeze kit)
• Extremely compact with its depth of only 18 cm, Unical's record among wall-mounted condensing boilers

KONx SLIM, thanks to the RCh chronothermostat, multi-program OT modulating, connected to the room and external probe supplied as standard, achieves seasonal efficiency equal to energy class A+ in heating.

HWS “Hot Water Speed” is the new KONx SLIM electronics that switches from the heating to domestic hot water function with the burner and pump always active, significantly improving the comfort of the user who does not have to wait for hot water.

Covered with a satin AISI 304 stainless steel casing with a tapered edge casing finish, KONx SLIM appears essential and very elegant, combining, with its hi-tech style, with the other appliances in the house

• Super small dimensions depth of only 18 cm
• Management of 2 temperature zones (high/low) by applying a second on/off thermostat
• Sliding temperature programmed to operate with the lowest possible flow temperature to promote energy saving
• Intelligent system loading to guarantee functionality If the pressure is less than 0.4 bar in the system circuit, automatic water loading starts for 30 seconds once a day. If the request is repeated several times, a warning signal appears on the remote control
• Post-circulation anti-overheating, the boiler automatically keeps the pump running for 5 minutes after the burner is turned off, preserving the components
• Chimney sweep function allows maintenance workers to carry out the checks required by current regulations regarding performance and emissions
• Multigas operation (natural gas or LPG) with simplified switching
• Double expansion vessel If necessary, an external auxiliary expansion vessel can be fitted (optional)
