Milwaukee Tankless Water Heater Experts

Tankless water heaters warm water as it’s needed instead of storing it in a tank. They can support a steady supply of hot water while taking up less space than conventional equipment. Mr. Holland’s installs, repairs, replaces, and maintains tankless water heaters in Milwaukee and nearby communities. Our plumbers work with gas and electric systems, troubleshoot inconsistent temperatures and error codes, and help homeowners determine when repair is an option. For new equipment, we calculate the required flow rate and temperature rise before recommending a unit.

Tankless Water Heater Installation

A tankless system must be sized for the number of fixtures that may use hot water at the same time. Installation may also require changes to the gas line, electrical service, venting, condensate drainage, or water connections. We account for all project requirements before placing and connecting the equipment.

Tankless Water Heater Repair

Temperature fluctuations, low flow, ignition failure, error codes, and unexpected shutdowns can originate from several parts of the system. Common causes include mineral buildup, restricted filters, sensor trouble, venting problems, or worn ignition and control components. A proper diagnosis separates a correctable issue from a larger equipment problem.

Tankless Water Heater Replacement

Replacement may be the better choice when an older unit has a failed heat exchanger, needs repeated repairs, or can no longer meet household demand. Changes in occupancy or water use can also leave the existing system undersized. We’ll evaluate the current installation and select equipment that fits the home’s hot-water needs and available utilities.

Tankless Water Heater Maintenance

Minerals carried by the water can accumulate inside the heat exchanger and restrict performance. Periodic flushing, filter cleaning, connection checks, and burner or heating-component inspections help keep the unit operating correctly. Maintenance frequency depends on water quality, usage, and manufacturer requirements.

Benefits of a Tankless Water Heater

Tankless equipment can be a practical alternative to a storage-tank system, but the advantages depend on correct sizing and installation. Consider how the household uses hot water, what utilities are available, and whether any supporting upgrades will be required. 

  • Hot water without a storage tank: Water is heated on demand, so a properly sized unit can continue supplying hot water without waiting for a tank to refill and recover. 
  • Lower standby energy use: Because the system doesn’t continually maintain a full tank of hot water, it avoids the standby heat loss associated with traditional equipment. 
  • A smaller equipment footprint: Wall-mounted tankless units free up floor space in basements, utility rooms, and other compact areas. 
  • No large tank to rupture: Tankless systems can still leak, but they don’t hold dozens of gallons that could escape if a storage tank fails.

Types of Tankless Water Heaters We Install in Milwaukee

Tankless water heaters differ in energy source, venting design, flow capacity, and installation requirements. The best fit for your home should be able to handle the home’s peak demand without exceeding the capacity of its gas or electrical system.

Electric Tankless Water Heaters

Electric models don’t require combustion venting and can work well for smaller households, limited applications, or point-of-use installations. Whole-home units may draw substantial power, so check the panel and electrical service before installation.

Gas Tankless Water Heaters

Natural gas and propane units generally support higher flow rates than electric models, making them suitable for homes with greater simultaneous demand. Installation requires an adequately sized gas supply, proper combustion air, and an approved venting system.

Condensing Tankless Water Heaters

Condensing models use a secondary heat exchanger to capture additional heat from exhaust gases. This design can improve efficiency and allows for lower-temperature venting, but it also produces condensate that must be drained correctly.

Non-Condensing Tankless Water Heaters

Non-condensing units use a single heat exchanger and release hotter exhaust. They have a simpler internal design but require venting materials rated for higher temperatures. Existing venting can’t be assumed compatible when replacing another type of water heater.

Affordable Plumbing Financing for Milwaukee

Installing a tankless water heater can involve more than replacing the appliance, especially when you need gas, electrical, or venting upgrades. Mr. Holland’s offers plumbing financing for approved Milwaukee-area homeowners looking to upgrade their tankless water heaters. Qualified applicants may be eligible for $0 down, 0% interest, and no payments for up to 12 months.
