Running out of hot water mid-shower or waiting for a tank to reheat gets old fast. A tankless water heater heats water on demand, delivering a continuous supply of hot water while using less energy than a traditional storage tank.
TMS installs, repairs, and maintains tankless water heaters for homeowners throughout Connecticut. Our licensed plumbers help you choose the right unit for your household’s hot water demand and install it to manufacturer specifications and current plumbing code.
How a Tankless Water Heater Works
Unlike a traditional tank water heater that stores and continuously reheats 40-80 gallons of water, a tankless unit heats water only as it flows through the system. When you turn on a hot water tap, cold water travels through the unit, passes over a high-powered heating element, and comes out hot, with no tank, no standby heat loss, and no waiting for a tank to refill.
This on-demand design is why tankless units are also called instantaneous or on-demand water heaters.
Benefits of Going Tankless
Endless Hot Water: As long as water is flowing, a tankless system keeps heating it: no more running out mid-shower during back-to-back use.
Lower Energy Bills: Because tankless units only heat water when it’s needed, homes typically see lower energy costs compared to a storage tank that keeps water hot around the clock.
Longer Lifespan: Tankless water heaters typically last 20 years or more, roughly double the lifespan of a standard tank unit.
Space Savings: Wall-mounted tankless units free up floor space in basements, closets, and utility rooms.
Reduced Risk of Leaks: Without a large tank of standing water, tankless systems eliminate the risk of a tank rupture flooding your basement or utility closet.
Is a Tankless Water Heater Right for Your Connecticut Home?
Tankless water heaters are a strong fit for most Connecticut households, but the right unit depends on a few factors:
- Household size and hot water demand: Larger households with simultaneous hot water use (multiple showers, dishwasher, laundry) need a higher-capacity unit or multiple units.
- Fuel type: We install both gas and electric tankless models, and can advise which fits your existing utility setup.
- Existing gas line and venting: Gas tankless units often require gas line upsizing and specific venting; something we assess during your in-home evaluation.
- Water quality: Connecticut’s hard water in some areas can affect tankless unit longevity, so we can discuss pairing your installation with a water softener if needed.
We’ll walk through your household’s hot water usage during your consultation and recommend the right size and type of unit: no guesswork, no oversized (or undersized) systems.
