These states are basically begging you to get a heat pump (arstechnica.com)

Nine states are teaming up to accelerate adoption of this climate-friendly device.

Death is coming for the old-school gas furnace—and its killer is the humble heat pump. They’re already outselling gas furnaces in the US, and now a coalition of states has signed an agreement to supercharge the gas-to-electric transition by making it as cheap and easy as possible for their residents to switch.

Nine states have signed a memorandum of understanding that says that heat pumps should make up at least 65 percent of residential heating, air conditioning, and water-heating shipments by 2030. (“Shipments” here means systems manufactured, a proxy for how many are actually sold.) By 2040, these states—California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island—are aiming for 90 percent of those shipments to be heat pumps.

“It’s a really strong signal from states that they’re committed to accelerating this transition to zero-emissions residential buildings,” says Emily Levin, senior policy adviser at the Northeast States for Coordinated Air Use Management (NESCAUM), an association of air-quality agencies that facilitated the agreement. The states will collaborate, for instance, in pursuing federal funding, developing standards for the rollout of heat pumps, and laying out an overarching plan “with priority actions to support widespread electrification of residential buildings.”

Gas boilers can by 95% efficient turning gas directly into heat energy.

Electricity generation is about 55% efficient at turning gas into electric energy.

So in a situation where you get 2 times or more heat out per kW you put in then you're lowering your carbon footprint even when electricity is created using gas.

2 to 4 times is not too difficult so

There's also the pretty big issue that the more methane is transported, the more leaks we have. As methane is 40× more potent than CO2 as a greenhouse gas every property we take off the gas network is a step towards reducing the need for that infrastructure.

Personally I can't fit an air source heat pump in my flat. It would be incredibly noisy and would probably require radiators to be refitted and taken up more space.

When my gas boiler goes I'll look at the cost of the standing price of a gas connection, annual servicing, and kW cost of gas. Then look at what a standard electric boiler costs.

It won't have the 2 to 4 times saving on kW cost a heat pump would have but it probably will come out similarly on cost. It will have a lower install cost. And it will reduce methane emissions.

If we haven't moved far enough to renewable energy by then my carbon footprint might actually go up. But the methane reduction will more than make up for that.
