Ambassador+ product info – Eco Heating Systems

Versatile and flexible heating

The Ambassador+ is a compact wall-hung central heating boiler with a practical design and surprising versatile possibilities. The stainless-steel heat exchanger, with a 10-year warranty, has a very long lifespan. The Ambassador+ units can simply be cascaded thanks to the integrated cascade controller. This way the units will operate as one central heating system.
