The importance of tankless water heaters increases dramatically in winter when it becomes difficult to maintain the temperature at an acceptable level. Tankless water heating equipment, as the name suggests, heats up water only when needed, unlike traditional water heaters. They don’t cause standby energy losses and, thus, save money. However, it is important to understand how tankless heating systems work and what model would be best for your heating needs.
Functionality of instant water heaters
Tankless heaters don’t use a storage tank rather water is heated directly. When you turn a hot water tap on, cold water runs through the unit where it is heated by an electric element or a gas burner. This means the tankless heating device delivers an instant supply of hot water and you don’t have to wait for it. Commonly used tankless heaters deliver hot water at a rate of 2 to 5 gallons per minute which is sufficient for most households.
As compared to electric heaters, gas-fired tankless water heaters produce higher flow rates. The efficiency of your instant water heater unit depends on how much hot water your house or building needs. Even gas units can fail to deliver enough supply of water in large households. Multiple uses, such as using a shower and dishwasher simultaneously can make it difficult for the tankless unit to meet the demands. If the demand for hot water is high in your house, consider installing more than one tankless unit.
Advantages and disadvantages
Instant water heaters are a good choice for households that consume 40 gallons or less of hot water daily. You can save up to 35% more energy by installing an instant unit in your house. Homes that use around 80 gallons per day can only save up to 15% of energy by replacing conventional storage tank water heater with a modern tankless unit. Nevertheless, instant heating systems are cost-effective.
When it comes to disadvantages, it is important to mention the initial high cost. However, tankless heating systems have longer service life which helps offset the initial high cost. Easily replaceable parts can extend the service life of your unit. On the other hand, traditional water heaters can only last for 10-15 years.
If the water heating system in your house is not producing a sufficient supply of hot water, consider replacing the old heater with a tankless one. You can call a plumber to get the installation or replacement done in a professional manner.
