Aside from the cost (which might come down), heat pumps have some inherent disadvantages - reliance on insulation, and slow ramp up time. So no more opening the windows at night for fresh air, then getting the house back up to temperature in the morning.
- 0ldskool 5y agoEverything you described would be a problem with hydrogen as well if not more so. You would need much much more insulation + special pipes for hydrogen usage. I don't know about slow ramp up times, I've never heard this. It takes mine about 10-30seconds for a 3 story house to start up. "So no more opening the windows at night for fresh air, then getting the house back up to temperature in the morning." I don't understand, how does hydrogen solve this problem? How is this not a problem for other sources? Random note: I'm all for heat pumps & all for hydrogen. They just aren't for the same use cases. Heat pumps are good for heating+cooling of spaces. Hydrogen is good way to store electricity when care about energy-to-weight and/or need quick fuelling.
