Pot Boiler?

The gas boilers of UK homes, produce twice as much carbon dioxide and eight times the nitrogen dioxide generated by all the country's power stations (https://www.theguardian.com/environment/2021/sep/29/uks-home-gas-boilers-emit-twice-as-much-co2-as-all-power-stations-study). Carbon dioxide is, of course, a potent 'greenhouse gas' the UK has pledged to dramatically reduce. Nitrogen dioxide is another atmospheric pollutant (also found in car exhausts), linked to respiratory illness and early deaths in thousands of people. Concomitantly, many consumers are facing rocketing gas prices for heating their homes and/or the collapse of their supplier. Insulate Britain, in spite of its activists now being threatened with imprisonment, are continuing to block roads and motorways. Whether one approves of Insulate Britain's methods or not, their demand that government transforms the energy efficiency of the UK's aging housing stock is entirely logical. It should be very clear that urgent action on both heating and insulation of UK homes is needed. Making vague promises, near the time of Cop26, would be completely meaningless. At the very least (they have even resisted this, thus far), the UK government should ban the fitting of gas boilers to new-build homes. Heat pumps run on electricity. They are also much more energy-efficient. Fitting them, will make the houses initially more expensive but it is a far cheaper option than later replacing gas boilers. There also needs to be a serious plan (with appropriate levels of funding), to upgrade the energy efficiencies of older houses. Without both, 'aspirations' to become carbon zero by 2050, are just 'pie in the sky'.
