Heating water uses about 18% of a home’s energy budget. This guide covers storage-tank water heaters, tankless water heaters, heat pump water heaters, solar water heaters with solar collectors, and condensing water heaters.
We share pros and cons, energy efficiency data, and installation cost tips. You will find the right fit for your home. Read on.
Key Takeaways
- Storage-tank heaters cost under $1,000, hold 40–80 gal, and meet big household needs but draw power all day (18% of home energy) and can raise bills by up to 30%.
- Tankless heaters run on gas or electric, cost $1,500–$3,000, save at least $100 a year by cutting standby loss, and give endless hot water but flow tops out near 2.5 gpm and may need multiple units.
- Heat pump heaters use air heat and electricity, run 2–3× more efficiently than standard electric models, cut operating costs by up to 50%, and work best in 40–90 °F but cost $3,000+ and need about 1,000 cu ft of space.
- Solar water heaters use flat-plate collectors, slash bills long-term, and run on free sun power but can cost $10,000+, lose up to 50% output on cloudy days, and need a backup heater.
- Condensing gas heaters cost $2,000+ installed, trap exhaust heat to cut gas use by about 30%, and lower carbon emissions but need sealed metal venting, a condensate line, and pro installation.
Storage-Tank Water Heaters
A holding vessel heats water all day, even when nobody takes a shower, and this can raise your running bills, though a jacketed cylinder can curb the worst heat fade. Talk with a licensed plumber about the setup fee, and see if it fits your family’s shower rush.
Pros: Affordable upfront cost, reliable for large households
These insulated tanks sell at a lower price than tankless water heaters. Homeowners choose sizes from 20 to 80 gallons. Insulated tanks curb standby heat loss and boost energy efficiency.
Pipe fitters handle them quickly.
High flow rates boost water heating for showers and dishwashers. Gas-fired models use natural gas to fire up fast and keep water warm. Technicians find them easy to repair and maintain.
They suit large households that need reliable hot water supply.
Cons: Higher energy usage, limited hot water supply
Storage-tank heaters lack energy efficiency and draw power all day to keep water hot. They raise utility bills by up to 30 percent. A bulky insulated tank eats laundry room space. It dumps heat into the room when idle.
A failing thermostat can hike operating costs. As the tank ages, small leaks can form. You need regular maintenance on valves and pipes.
Storage water heaters often run out of hot water on busy mornings. A typical tank holds 40 to 50 gallons. Large families can deplete that in two showers. Then cold water flows in. You wait while the tank refills and reheats.
Kids and pets can get cranky in the cold.
Tankless Water Heaters
Say goodbye to bulky storage tanks with an instantaneous heater that warms water only when you need it. This powerhouse draws on a natural gas burner or electric heating element to meet high hot water demand, yet it may choke if multiple taps run at once.
Pros: Energy-efficient, endless hot water supply
Energy Star certified units slash running costs by cutting standby heat loss. They meet energy efficiency goals and can save a household at least $100 annually on utility bills. These on-demand water heaters cut the need for frequent plumbing services.
They boast a space-saving design and a longer lifespan than conventional tank water heaters.
Tankless heaters fire up in seconds and deliver an endless hot water flow for showers, laundry, and dishwashing. They run on natural gas or electricity to power a heat exchanger. This setup avoids the risk of leakage or burst tanks.
Higher installation cost pays back through fuel savings and durable components over two decades.
Cons: Higher upfront cost, limited flow rate
Tankless water heaters cost far more up front than standard tanks, often topping $1,500 to $3,000 for the unit. Plumbing services for installation can push the total past $4,000, since installers upgrade pipes and venting.
Tight budgets take the hit.
These on-demand units reach only about 2.5 gallons per minute, limiting hot water supply when two showers run. Larger households may need two or three heaters to meet peak hot water demand.
That extra gear adds to installation costs and drives operating costs higher.
Heat Pump Water Heaters
A heat pump water heater moves heat via a refrigerant cycle, pulling warmth from the air like a fridge in reverse. You set the temp on an electronic control panel and the unit sips electricity rather than guzzles it.
Pros: Energy-efficient, eco-friendly
Heat pump water heaters run on electricity and pull warmth from the air, like a heat sponge. They use a scroll compressor and vacuum insulated tank to trap energy. You dodge high operating costs.
These systems work two to three times more efficiently than standard electric models. They need little upkeep, cutting water heater repair calls.
They shrink your carbon footprint, thanks to a renewable energy source. Some states offer rebates or tax credits, so you snag cash back. These units team well with solar panels for extra energy savings.
You enjoy endless hot water, without sky-high bills.
Cons: Requires more space, less effective in cold climates
Heat pump water heaters demand big room. Plumbing pros say at least 1,000 cubic feet must sit around the insulated tank and core components. Many homeowners lose garage or laundry space to that need.
High purchase and installation costs can jump past $3,000 with labor and parts.
Performance dips in chill. Units run best between 40-90°F, so they hit energy-efficient targets in mild zones. A U.S. DOE report found output drops fast below 40°F. That means your hot water supply can run low when winter winds bite.
Solar Powered Water Heaters
Flat-plate collectors trap solar energy, then a heat exchanger warms your insulated tank like a cozy blanket. You slash monthly bills, but you shell out higher plumbing services fees and need a sunny roof.
Pros: Renewable energy source, long-term savings
Sun-powered water heaters tap solar energy to heat water. They use a renewable energy source, run with high energy efficiency and need little maintenance. These units protect the environment with a sun-thermal array.
Homeowners enjoy long-term savings on utility bills. Installation costs remain higher than for tank water heaters. Many owners add a backup tankless water heater to protect hot water supply on cloudy days.
Cons: High installation cost, weather-dependent
Installation cost may reach $10,000 or more for a solar water heater. Local plumbers or solar technicians handle every professional installation. Flat-plate collectors drive up those upfront expenses.
Cloudy skies cut hot water output by up to 50 percent. Low winter sun angles leave storage tanks cold. Owners in snowy areas depend on backup heating like gas or electric units.
Condensing Water Heaters
A condensing water heater uses a second heat exchanger to pull heat from exhaust gases before they escape the flue. A plumber reads the pressure gauge and tweaks the vent to cut your gas bills.
Pros: Efficient for homes using natural gas, lower energy bills
Condensing water heaters trap heat from exhaust, so homes burn less natural gas. Gas-savvy families see energy savings up to 30 percent on their monthly bills.
Skilled plumbing services handle the venting and burner swap, so you squeeze every bit of warmth from your heater. That cuts carbon emissions. It feels like a green upgrade for your home.
Cons: Expensive upfront cost, requires proper venting
These condensing water heaters cost more at install time. They can top $2,000 for unit and labor. Many need plumbing services to handle vent work. Pro plumbers can boost installation cost with extra fees.
Moisture from the flue can spark corrosion risks. Only natural gas homes suit this setup.
Proper venting needs sealed metal exhaust piping and a condensate line. Installers must meet local code for safe air flow. Flue moisture can eat at vent pipes fast. That damage can void the unit warranty.
Homeowners must hire licensed plumbers for each install.
Factors to Consider When Choosing a Water Heater
Energy efficiency works like a car’s gas mileage—higher ratings give you lean bills. Compare installation costs to operating costs, and peek at safety valve specs before you call plumbing services.
Household size and hot water needs
Families of four often need a 40 to 50 gallon storage-tank heater to match peak showers and loads. A 30-Gallon Insulated Vessel can lose heat if first-hour rating falls short. Plumbers use a Gallons-per-minute meter to time showers and gauge daily peak usage.
Installing tankless water heaters boosts energy efficiency and cuts standby heat loss. You may need two on-demand units for a large clan. A GPM gauge tracks true flow rate under multiple taps.
Proper sizing keeps operating costs in check and meets expected hot water demand.
Energy efficiency and long-term cost savings
Heaters use heat pumps to move warmth into water for showers, dishes, and laundry. Heating water accounts for about 18% of a home’s energy budget. Electric heat pump water heaters are energy-efficient.
They cut operating costs by up to half. A flow meter helps track energy use.
Energy Star certified tankless water heaters can save at least $100 each year. Insulated tank units suffer standby heat loss in storage tank systems. On-demand water heaters avoid that waste by heating water only when needed.
Professionals may charge extra for professional installation, but lower energy costs often cover installation costs within a few years.
