Benefits of a Tankless Water Heater

Tankless equipment isn’t the right fit for every property, but it can offer several advantages when properly sized and installed for the home’s hot water needs. 

  • On-Demand Hot Water: Tankless systems heat water as it’s needed instead of relying on a limited supply stored in a tank. 
  • Reduced Standby Energy Use: Because water isn’t continuously kept hot in a storage tank, tankless equipment can reduce energy used to maintain stored water temperature. 
  • Compact Equipment: Tankless water heaters mount to a wall and generally take up less floor space than traditional storage-tank systems. 
  • Long-term System Life: With proper installation and routine maintenance, tankless equipment can provide dependable service for many years. 
  • Flexible System Options: Gas and electric configurations allow homeowners to compare equipment based on available utilities, household demand, and installation requirements.

Types of Tankless Water Heaters We Install in Watertown

Tankless water heaters are available in several configurations, and the right choice depends on the home’s available utilities, hot water demand, installation requirements, and efficiency priorities. Carew can help you compare the options before selecting new equipment.

Electric Tankless Water Heaters

Electric tankless units use electrical heating elements to warm water as it passes through the system. They don’t require gas combustion or venting, although larger systems may require substantial electrical capacity to keep up with household hot water demand.

Gas Tankless Water Heaters

Gas tankless water heaters use natural gas or propane burners to heat water on demand. Their higher heating capacity can make them a practical option for households with greater simultaneous hot water needs, provided the property has the necessary gas supply and venting.

Condensing Tankless Water Heaters

Condensing tankless systems capture additional heat from combustion exhaust before it leaves the unit. This allows them to recover energy that would otherwise be lost through venting and can provide higher operating efficiency than many non-condensing designs.

Non-Condensing Tankless Water Heaters

Non-condensing tankless systems use a primary heat exchanger to heat the water before exhausting combustion gases outside. They typically have a simpler design, but venting requirements and overall efficiency differ from condensing equipment.

Affordable Plumbing Financing in Watertown

Replacing a traditional water heater with a tankless system can involve equipment, plumbing, electrical, gas, or venting upgrades depending on the property. Carew offers financing through Wells Fargo for qualified customers, providing another way to manage the cost of eligible tankless water heater installation and replacement projects.
