Domestic Water Heating Types
|
Storage Water Heaters In multiple-unit dwellings such as high-rise apartments, the most common hot water solution is a storage water heater, sometimes linked with additional storage tanks. With the right mixture of heating and storage, this system can provide continuous hot water during peak demand times and can replenish itself when demand drops off. Because the hot water is stored for future use, the BTU ratings can be kept relatively low that saves money because both the gas pipe and the actual tank size can be minimized. This type of system is also popular in commercial settings where large amounts of hot water are needed for a manufacturing process, shower or cleaning. All methods of heating water have advantages and disadvantages, depending on each unique situation. Find manufacturers’ information on storage heaters. Contact a contractor for more information on storage water heaters. |

Some commercial properties with small requirements for hot water use a residential water heater to satisfy their needs.

Boiler

In situations where large amounts of hot water are needed for a commercial or industrial application, it makes sense to piggy back onto the existing heating system, such as a boiler, for supplementary hot water needs. Because the boiler is already in place, the capital costs of installing the domestic water system are relatively low. All that is needed is an extra loop from the existing boiler to a storage tank that would deliver water for cleaning, hand washing and other day-to-day activities. |

The only disadvantage to this type of supplementary system is that the main boiler must be on at all times to heat the water. That’s why this system is best used where there is a large demand for hot water in the facility that keeps the boiler going year round.

Tankless Tankless water heaters are designed to deliver a fixed amount of hot water to a specific location almost instantly. They use very little room because there is no storage tank to fill, which also makes them very efficient. There are no standby losses as the water sits in the tank waiting to be used. When demanded, water travels from the heater to the outlet. Although there is a short warm-up time, the hot water is delivered almost immediately. More importantly, it only heats what is needed when it is required. Tankless water heaters are not designed to deliver large volumes of hot water, but in specific situations, they could be an ideal solution. |

Booster Water Heating
One of the specialized uses of hot water is to “boost” the rinse temperature
in a dishwasher from 60° to 82°C (140° to 180°F). Sometimes a commercial
laundry requires hotter water for specific cleaning situations. Natural gas
equipment provides a variety of solutions for boosting water temperature.
