Committed to your comfort for every tankless water heater install

A tankless water heater can give hot water on demand at any hot water faucet in the house. It takes less space than a tank and can improve energy use. MSP handles tankless water heater installation from start to finish. We remove the old unit, install the new water heater, and connect the water lines, gas supply, and power. We also check water pressure, pressure relief valve, shut off valve, and exhaust vent so the system is safe and ready to run.

What factors does MSP consider when determining price?

Whole home vs point of use units

Whole home tankless water heaters serve all hot water taps, showers, and fixtures. Point of use units serve one area, such as a kitchen sink or laundry room. Whole home systems cost more but can support many fixtures at once. Point of use units are smaller and often cost less to install.

Flow rate

Flow rate is how many gallons per minute the tankless unit can heat. A higher flow rate usually costs more. A higher rate can run more than one hot water faucet or shower at the same time. The plumber checks family size, number of fixtures, and hot water habits to suggest the right flow rate.

Efficiency

Many tankless water heaters are built for energy savings. A more efficient unit costs more at the start but often lowers long term energy costs. MSP can explain how efficiency ratings, water temperature settings, and usage affect bills over time.

Fuel source

Tankless gas water heater systems use natural gas or propane. Electric tankless heaters use electrical supply from a circuit breaker. Gas often costs less per unit of heat in Minneapolis-St. Paul. The choice depends on current location of gas lines, electrical junction box, local codes, and cost to install each option.

| Why Go Tankless?

Tank vs. tankless: which is better for my home?

Both tank water heater and tankless water systems can work well in a home. The better choice depends on budget, space, and hot water use.

  • Installation Cost: A tank water heater often has a lower install cost. A tankless system can cost more due to venting, gas line work, and new water lines.
  • Performance and comfort: A tank stores hot water in a water tank and can run out during high use. A tankless water system heats water as it flows, which can give near endless hot water when sized and installed correctly.
  • Energy use: A tank keeps water hot even when no one is using it. A tankless heater only runs when a hot water faucet is on. This can reduce waste and improve energy use.
MSP helps homeowners compare systems and choose the best fit.

| Process

Our 5-star tankless water heater installation process

We schedule a visit to the home

The process starts with a call or online request. A service member records the location, current system details, and preferred date and time. A visit can often be set for the same day or within a few days, depending on schedule.

We discuss hot water needs

When the plumber arrives, they talk about family size, showers, tubs, and hot water habits. They may check the old water heater, water pressure, gas line, electrical supply, and vent path on an outside wall. Questions about energy savings, capacity, and flow rate are welcome.

We help select a tankless system

The plumber shares options for tankless gas water heater or electric units. They review flow rate, location, venting, and local codes. They also explain the water heater replacement process, new water lines, isolation valves, and water connections. Upfront pricing is given for each new unit so the homeowner can choose the best option for the house and budget.

We install the tankless system

If you have an existing water heater, we'll remove it from the premises for you. From there, we'll perform any adjustments to your home's plumbing, electrical, or ventilation that are required to install the new system. Before we leave your home, the new system is always tested to ensure it's working at optimal efficiency.
