Gas heating systems are increasingly popular as they provide heat while being energy-efficient and reliable. Among these gas heaters, natural gas heaters are much more efficient than LPG and are cheaper than other sources of getting warmth, such as electricity. Heaters operating on Natural Gas convert over 90% of the energy to heat, making them way more efficient than power, and these are also environmentally friendly.
