Is it cheaper to heat my home with gas or electricity

Jun 07, 2018 · If you take the heating bill part of this (approx. £950) with an 80% efficient gas boiler and a unit of gas is 4p / kWh it would suggest using 23650kWh of gas. If you used an electric heating system operating at efficiency it would require 18920 kWh of electricity which indeed is less in pure numbers terms, but at 11p/kWh it would

Internal combustion engine - Wikipedia

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.
