I have always been interested in energy innovation and learning about alternative means of home heating. There are a number of options available that have a reduced environmental impact compared to the traditional gas boiler. But have you considered hydrogen? Hydrogen as a fuel is discussed more and more, it’s a hot topic throughout the HVAC and environmental communities and although the surge in battery viability has seen a slower progress of the hydrogen technology, there are viable products available in the domestic market. I interviewed Patrick Wheeler, Director of VitoEnergy to find out more about the Viessmann Vitovalor Hydrogen fuel cell unit. Patrick had a lot to teach me about the technology, the sustainability and the financial viability for the end users.
