Despite the reputation of fossil fuels, natural gas is one of the best choices to use to heat your home, your food, and your water. Natural gas burns cleanly and efficiently and gives the user greater control of what they need, whether that is cooking a delicious meal or heating water for a shower. New hot water heaters and tankless water heaters can improve on this already efficient fuel. New gas-powered water heaters can reach nearly 100% efficiencies and heat water very quickly. An added bonus of tankless water heaters is that they provide hot water instantly and endlessly.
