We moved to the area a year and a half ago. Our home has many original/aged items. Literally from the month we moved in (updating the sump pump and main water shut offs) to just last week (furnace and water heater) Andersen has been great

Our water heater went out unexpectedly. We got several quotes and Andersen by far provided the most value for money. From getting the quote to scheduling the work, they were so easy to work with and turnaround time was great. The technician

I recently had a great experience with Andersen Plumbing and Heating. The heater in our house stopped working in the morning, and they were able to send someone out to fix it the same day I called. Adam, the technician they sent, was fantastic.

Tankless Water Heater Installation & Replacement in Aurora, IL

Our team handles tankless water heater installation in Aurora, IL, for homes making the switch from a traditional tank. We size the unit to your household’s hot water use, check your gas line or electrical capacity, and plan the venting before any work starts. That planning matters, because an undersized unit leads to lukewarm showers when two fixtures run at once.

Our winters push these systems harder than most. The water coming into your home gets much colder in January than in July, so the heater has to work harder to reach the same temperature. We account for those cold months when choosing a unit, so you are not caught short when you need hot water most.

If your current unit is aging or giving you trouble, we also provide tankless water heater replacement in Aurora, IL. We remove the old unit, update fittings and venting as needed, and install a model that fits how your family uses water today. Financing options are available to make the upgrade easier on your budget.

How to Tell That a Tankless Water Heater Is Right for Your Home

A tankless unit can be a smart move if your current tank is getting up in years and you are already planning a replacement. It also makes sense if your family keeps running out of hot water or you want to free up floor space in the basement. Because tankless units only heat water when you use it, they avoid the energy lost keeping a full tank warm all day.

Many homes in the Aurora area deal with hard water, which can leave mineral scale inside a tankless unit over time. That does not rule out going tankless, but it does mean regular flushing or a water softener should be part of the plan. We will talk through your water, your space, and your budget with you. If a traditional tank is the better fit for your home, we will tell you that too.
