Looking for a powerful, durable, and future-proof boiler solution for your heat pump system? Meet the LMNT Fast Boiler Tank 400L – a horizontal, indirectly heated buffer tank of exceptional quality. Specially designed for the efficient storage and rapid availability of hot water, this boiler pairs perfectly with sustainable heat sources such as heat pumps and solar thermal systems.
The tank is made of Duplex 2205 stainless steel, a premium-grade alloy known for its excellent corrosion resistance and strength. This makes the tank highly resistant to high temperatures, pressure fluctuations, and condensation – significantly extending its lifespan. The material is suitable for both domestic hot water and heating applications, and offers outstanding thermal and mechanical performance.
With a capacity of 400 litres and a powerful integrated spiral heat exchanger, this Fast Boiler ensures rapid thermal energy transfer. The coil is optimised for low-temperature heating sources like air-to-water heat pumps and delivers excellent performance, even at low inlet temperatures.
The LMNT 400L can be installed horizontally on the floor or wall-mounted, with multiple connection points (top and side) for flexible integration into any system layout. Thanks to its high-performance PU insulation, heat loss is kept to an absolute minimum – ensuring an energy-efficient and cost-effective operation.
