Companies are on board the green movement and are dong what they can to help our environment and are designing and manufacturing products to help achieve that. Light bulbs have changed to use less energy, hybrid cars are being developed to lessen carbon emissions and relatively new to the market are Tankless Water Heaters and gas boilers. Gas boilers are a new solution for energy efficiency in heating and maintaining hot water. No more large water tanks are needed in your basement. These new designs can simply hang on the wall and are much more environmentally friendly. Baxi is one company that manufacturers these systems and keeps its commitment to the green movement. Several of the baxi models have won awards for their efficiency.
