Jun 26, 2019 · My heat pump avoids 1313 kg CO2e a year. It means that after less than 1.5 years, a heat pump starts saving carbon compared to a gas boiler, even if the gas boiler is replaced before the end of its life. Hence, from a carbon perspective, it makes sense to replace a gas boiler even if it was just installed.
