Keep the radiators or heated floor you love, and swap the gas boiler behind them for an electric heat pump. It’s the same gentle, even warmth, just without the gas.
A common sign
“I love our radiators, but I’m sick of paying for gas to run them.”
About hydronic heating
Hydronic heating warms a house by running hot water through radiators or pipes in the floor. Traditionally that water was heated by a gas boiler. An air to water heat pump does the same job using electricity, pulling heat from the outside air.
Heat pumps work best with slightly cooler water than a boiler, so some radiators may need to be swapped for bigger ones to keep rooms just as warm. A good installer will check every room before quoting.

Keeping radiators or in-slab heating you already have
Ask whether your existing radiators and pipes can stay, and which rooms, if any, would need larger radiators.
Not sure where to start?
Don’t waste money on upgrades you don’t need. A professional home energy assessment shows where your house loses heat and power, so your budget goes where it makes the biggest difference.

More in gas to electric
Replace the gas appliances one by one, hot water, heating, cooking, and stop paying two connection fees to keep the house running.
A heat pump uses a fraction of the electricity of an old electric tank, and it is the usual first swap when a gas system fails.
Roof collectors with a boosted tank. A different product from a heat pump, and still the cheaper option on some rooftops.
Warms the pool with an electric heat pump or solar collectors on the roof instead of gas. Pairs well with rooftop solar, and a pool cover keeps the heat in.
Replaces an old single speed pump with a variable speed one that runs slower for longer, so keeping the water clean takes less power.
Faster than gas, and it takes the last flame out of the kitchen. Usually needs its own circuit run from the switchboard.
One unit for one room, or several heads off one outdoor box. The cheapest way to heat and cool the rooms you actually use.
Ducted through the whole house. The vents from a ducted gas furnace can often be reused, though not always, so ask before you count on it.
A filter clean and a gas check keeps a system running at the efficiency it was sold at. Cheap next to replacing it early.
An older board often cannot take an induction cooktop, a heat pump and a charger at once. This is the job that unblocks the rest.
The last step. Once every gas appliance is gone, removing the meter is what actually ends the daily supply charge.
