The Workhorse Options

Standard Water Heaters

Tank style water heaters are the most common choice in Minnesota homes. They're reliable, affordable upfront, and straightforward to install and service.

🔥

Gas Tank (Atmospheric Vent)

The classic natural gas water heater. Uses a standing pilot light and vents combustion gases through a flue and chimney. A proven, no frills workhorse for most homes.

30 to 80 gallon capacity options
Recovery: ~20 to 22 gallons/hr (per 40k BTU)
Lifespan: 8 to 12 years
Requires existing B vent or chimney
No electricity needed to operate

💨

Power Vent Gas

Similar to atmospheric, but uses an electric blower to push exhaust out through PVC pipe. Great for homes without a traditional chimney or with longer vent runs.

Vents horizontally through PVC
More flexible installation locations
Requires nearby 120V outlet
Lifespan: 8 to 12 years
Common in finished basements

⚡

Electric Tank

Heats water using upper and lower electric elements. No venting required, making it ideal for tight spaces or locations without gas service.

30 to 80 gallon capacity options
Requires 240V dedicated circuit
Slower recovery than gas
Lifespan: 10 to 15 years
Lower install cost; higher operating cost

Upgrade Your Efficiency

High Efficiency Water Heaters

Modern high efficiency units cost more upfront but can significantly cut your monthly energy bills. Some qualify for utility rebates, so ask us about current incentives.

Tankless Gas (On Demand)

Heats water only when you need it, with no standby heat loss. Provides unlimited hot water and can cut energy use by 30 to 50% compared to a standard tank.

Endless hot water supply
Efficiency: up to 0.96+ UEF
Lifespan: 15 to 20+ years
Requires dedicated gas line (often upsized)
Annual descaling recommended in hard water areas

Best for Electric Homes

🌡️

Heat Pump / Hybrid Electric

Uses electricity to move heat from the surrounding air into the water rather than generating heat directly. Two to three times more efficient than a standard electric tank.

UEF ratings of 3.0 to 4.0+
May qualify for utility rebates
Requires adequate air space (700+ cu. ft.)
Works best in unconditioned spaces 40°F+
Lifespan: 10 to 15 years

Commercial & High Demand

🏭

High Recovery / Commercial Gas

Built for high hot water demand: large families, home additions, or light commercial use. Higher BTU input means faster recovery and less running out during peak demand.

75,000 to 100,000+ BTU input
50 to 100 gallon capacity
First hour rating well above standard units
Power vent or direct vent configuration
Ideal for 5+ person households or additions

Maintenance Matters

How to Flush Your Water Heater Annually

Sediment naturally builds up at the bottom of tank water heaters, especially with hard water like much of the Twin Cities. Annual flushing removes that buildup, improves efficiency, and extends the life of your unit.

Turn Off the Heater

For gas units, turn the thermostat dial to "Pilot." For electric units, shut off the breaker at your panel. Never flush a water heater that's actively heating, or you risk thermal shock to the tank.

Connect a Garden Hose to the Drain Valve

Find the drain valve near the bottom of the tank and attach a garden hose. Run the other end to a floor drain, utility sink, or outside. The water will be hot and may carry sediment, so be careful where you aim it.

Tip: If your drain valve is old or corroded, have a plumber replace it. They're inexpensive and tend to drip once disturbed.

Open a Hot Water Faucet in the House

Open a hot water tap (a tub faucet works great) and leave it open for the whole flush. This keeps a vacuum from forming and lets the tank drain freely.

Open the Drain Valve and Flush

Open the drain valve and let the tank empty. The water may come out discolored or sandy. That's normal and exactly what you're removing. Once it runs clear, close the drain valve.

Tip: For heavy buildup, briefly turn the cold supply back on while the drain is open to "power flush" the sediment out.

Refill the Tank

Close the drain valve, disconnect the hose, and fully open the cold water supply. Keep that hot faucet open. Once water flows steadily with no more air sputtering, the tank is full.

Restore Power and Check for Leaks

For gas units, set the thermostat back to your desired temperature (120°F is standard). For electric, flip the breaker back on. Close the hot tap and check the drain valve for drips. Allow 30 to 60 minutes for the water to fully reheat.

Tip: While you're there, check the T&P (temperature and pressure) relief valve. Lift the lever briefly to make sure it's not seized. If water doesn't flow and stop cleanly, it may need replacement.

When to call a pro instead: If your water heater hasn't been flushed in several years, the drain valve is seized or leaking, you see rust colored water, you hear rumbling or popping while it heats, or you're unsure about any step, give us a call. A small service visit costs a lot less than an emergency replacement.

Common Questions

Water Heater FAQ

A few of the questions we hear most often from homeowners in the Twin Cities area.

How do I know when it's time to replace my water heater?

Most tank water heaters last 8 to 12 years. Key signs it's time: age over 10 years, rust colored water, visible corrosion or leaking from the tank itself, lukewarm water despite a working thermostat, or a unit that's needed multiple repairs. Repairs on older units often make less financial sense than replacement.

Do I need a permit for a water heater replacement in Minneapolis or St. Paul?

Yes. A permit is required for water heater installations in both Minneapolis and Saint Paul. As a Master Plumber owned company, Pipe Daddy Plumbing pulls the permit for your job so you're always covered. Unpermitted work can create serious issues when you sell your home.

What size water heater do I need?

It depends on household size and peak demand. A general guide: 30 to 40 gallons for 1 to 2 people, 40 to 50 gallons for 3 to 4 people, 50 to 80 gallons for 5+ people. Tankless units are sized by flow rate (GPM) rather than storage. We'll assess your home's demand and recommend the right fit.

Are there rebates available for high efficiency water heaters?

Sometimes. The federal tax credit for heat pump water heaters ended on December 31, 2025, so units installed in 2026 no longer qualify for it. Xcel Energy and CenterPoint Energy have offered rebates on qualifying high efficiency units, but those programs change often. We'll help you check what's available at the time of your installation.

Can you install a tankless water heater where my tank unit was?

Often yes, but it depends on your gas line size and venting. Tankless units typically need a larger gas line (¾" or 1") and dedicated PVC venting. We'll assess your existing setup and give you an honest recommendation, including whether upgrading makes sense for your home.

What temperature should I set my water heater to?

120°F is the standard recommendation: hot enough to prevent bacterial growth (including Legionella) while reducing scalding risk and energy waste. Households with immune compromised members, or where water travels a long distance, may benefit from 130°F at the tank with a mixing valve at the fixtures.
