In common terminology, a hybrid (dual-fuel) heat supply system combines a gas boiler and a heat pump. These systems are considered the most energy-efficient of the currently existing autonomous household heat supply systems. Analysis of the efficiency and carbon footprint of household heat supply systems shows that at low atmospheric temperatures and the use of radiator-type heating devices, the question of the advantage of heat pumps is not unambiguous. A new solution for a thermal generator (Patent for invention RU 2782081 C1) is proposed - a hybrid gas-electric boiler that has a number of advantages when operating systems at atmospheric temperatures from 0 ° C to + 10 ° C. The technical characteristics of the hybrid boiler, the purpose and the field of effective application are determined. A comparison of the carbon footprint of a hybrid boiler with heat pumps and a typical gas boiler is presented. The area of effective use of the invention is a household with a heated area of up to 100 m2, apartment heat supply. The main advantage of a hybrid gas-electric boiler is the exclusion of cyclical operation of the heat generator at a low thermal load, characteristic of space heating at atmospheric temperatures from 0 ° C to 10 ° C.
