Three Protherm Ranges with Instant DHW Heating

Protherm offers condensing boilers with instant domestic hot water (DHW) heating in three product ranges, differing mainly in output and equipment level:

Puma Condens 18/24 MKV – the most compact range with an output of 6.0 – 18.3 kW, suitable for smaller flats with lower heat loss.
Gepard Condens 18/25 MKV – the best-selling range, 18/25 kW output, aluminium heat exchanger, maximum DHW flow rate of 12.1 l/min at Δt 30 K, weighing just 33.4 kg. Ideal for a flat or house with one bathroom, also available in a package with the Thermolink P control.
Panther Condens 20/26 KKV – a slightly more powerful range (20/26 kW) for households with higher heat or hot water demand, also available in a package with the MiSet room control.

Which Model to Choose

If you're looking for a proven and affordable option for a typical flat with one bathroom, the Gepard Condens 18/25 MKV is the most versatile choice, offering a good balance of output, DHW flow rate, and price. For a smaller space or lower heat loss, the more compact Puma Condens is sufficient. If you need higher output (larger house, higher hot water demand), choose the Panther Condens.

If you're also considering room control, the packages with Thermolink P (Gepard) or MiSet (Panther) save you the hassle of choosing compatible accessories.
