Ah, in the US gas is the most common and I'm not sure about the UK — just going off what the article mentioned.
But yeah, my understanding is that burning gas in your home produces less CO2 than burning coal or oil, but they ALL pollute (and gas often has methane leaks from pipelines which is worse for warming than CO2). Whereas a heat pump emits nothing, is ~3x more efficient than gas combustion, and will increasingly cause no emissions as the grid is powered by renewables.
It's far better to emit NO pollutants in your home (and cars!) than to emit less, especially since polluting home infrastructure is replaced every ~15 years and pollutes for its entire lifetime.
- nly 5y agoAre all properties suitable for a heat pump though? That's the question. My understanding is they are basically aircon units running in reverse, which means outside heat radiators?
- roywiggins 5y agoIf you can't fit a heat pump, resistive heating should work fine, but it will be more expensive to run. It would obviously put more load on your renewable grid, so you'd want to put heatpumps wherever possible, but at least it's better than burning gas/oil/coal for heat.
- Glench 5y ago> Are all properties suitable for a heat pump though? That's the question. Generally, yes, but of course it always depends on specific circumstances. Read up on heat pumps! They're really cool. And yes they're like air conditioning units that can cool and also heat. In addition to heat pump space heating there are also heat pump hot water heaters and heat pump clothes driers and it seems both are more efficient and non-polluting. It feels magical that they can pull heat from outside in the winter, but that's what they do! The more recent units can even do it in very cold temperatures.
