Of note, the heating input capacity of the water heater – for gas units, measured in ''BTUs per hour'' – is closely related to a heater''s recovery rate (along with other factors such as insulation value of the tank). The higher the BTU input (or heater wattage rating, for electric tanks), the higher the recovery rate.
In the energy utilization infrastructure, about 75% of the fossil fuel consumption is used to provide and maintain heat, leading to more than 60% waste heat of the input energy

2 · An electric boiler heats water using electricity and circulates that warm water through radiators or underfloor heating pipes. Usually, these systems include a large hot water cylinder to store the heat, and are paired with special electric meters, which provide cheaper electricity units at certain times of day.
Electric models can be energy-efficient in all climates, and the repair and replacement costs are relatively low. Additionally, water heaters powered by gas or propane withstand electrical outages that may occur. Another consideration for a storage tank water heater is the recovery rate, or the number of gallons of water it can heat in an
Calculated based on an electric storage water heater of <=55 gallons capacity. Drain-water, or greywater, heat recovery systems capture the energy from waste hot water—such as showers and dishwashers—to preheat cold water entering the water heater or going to other water fixtures. Energy savings vary depending on individual household
The low-grade waste heat is widely distributed in various scenarios and lacks suitable technologies for recovery. Carnot battery is a large-scale electrical energy storage technology, and pumped thermal energy storage (PTES) is one of the branches in which the waste heat can be efficiently utilized.
Chemisorption heat pump and thermal storage based on reversible chemical reactions, such as ammonia-salt systems, has attracted increasing attentions over the last decades as a result of its low grade heat utilisation, long-term storage ability, and the higher energy densities in comparison with physisorption systems, e.g. water- or methanol-based
Heat energy recovery. In the early 1970s, the severe Middle-East oil crisis had led to a sharp increase in fuel prices in the industry. Thus, the efficient utilization of fuel has overwhelmingly attracted researchers'' attention [] addition, with more significant concerns placed on environmental sustainability, recovery energy from dissipated waste heat by fuel
Both the energy recovery and storage technologies for EVs have been aimed to save more electrical energy for driving thereby stretching the travelling range, alleviating range anxiety, and improving energy efficiency. The advantages of applying TES technologies in EVs lie in two aspects: Thermal storage for electric vehicle cabin heating in
• Heat Pump Water Heaters. Heat pumps transfer energy from the surrounding air to water in a storage tank. These water heaters are much more efficient than electric resistance water heaters and most effective in warm climates with long cooling seasons. • Solar Water Heating. While the initial purchase price of solar water heaters is high
Electric Thermal Storage is a system that stores electric heat during the night when rates are lower, and releases the heat throughout the day. This doesn''t save energy overall, but it can save you money based on the difference in power rates between day and night. Check whether your area and electric utility offer time-of-use electricity rate

Can be 2 to 3 times more energy efficient than conventional electric resistance water heaters. ENERGY STAR qualified models can save almost $300 annually on electric bills.
These include the size of the water heater, the energy source (gas, electric, or heat pump), the efficiency of the water heater, and the temperature of the incoming cold water. Larger water heaters with higher energy input rates will have a faster recovery rate compared to smaller water heaters with lower energy input rates.
