Indirectly fired Fast Boiler tank CAWT-500L Duplex 2205 500 liter with coil (Spiral) For heat pump

LMNT Fast Boiler Tank 500L – Indirectly Fired Stainless Steel Buffer Tank with Spiral for Heat Pump Installations

Experience top performance and maximum sustainability with the LMNT Fast Boilertank 500L , a high-quality, indirectly fired boiler from Coolmark, specially designed for modern heat pump installations and sustainable energy solutions. This 500-litre boiler combines storage capacity, speed and efficiency in one robust, horizontal unit – perfect for residential and commercial applications where hot water comfort and energy savings are key.

The tank is manufactured from high-quality Duplex 2205 stainless steel , known for its exceptional resistance to corrosion, stress corrosion cracking and high temperatures. This makes the LMNT series extremely suitable for long-term use under demanding conditions, such as in heat pumps, solar boilers and hybrid heating systems.

Thanks to the integrated spiral heat exchanger (coil), the water is heated efficiently and quickly via an indirect system. This heat exchanger is specially optimized for low temperature sources such as heat pumps, which makes the efficiency significantly higher than with conventional boilers.

The Fast function of this boiler guarantees a shorter heating time and a continuous availability of hot water, even at higher peak loads. This makes the LMNT 500L particularly suitable for larger households, hotels, sports facilities or utility buildings.

With a capacity of 500 litres, this boiler tank offers ample buffer storage, making it suitable not only for hot water supply, but also as a puffer tank in advanced heating systems. The high-density insulation minimises heat loss, contributing to even more efficient energy use.

✅ Key benefits:

• 500 litre capacity – ample storage capacity for sanitary hot water and heating

• Duplex 2205 stainless steel – corrosion-resistant, hygienic and suitable for high temperatures

• Spiral heat exchanger – optimized for heat pumps and low temperature systems

• Indirectly fired – suitable for sustainable heat sources such as heat pumps and solar energy
