Water Heaters Chicago IL

There’s never been a better time to upgrade efficiency and rewards through the installation of an instantaneous hot water heater. Today’s hot water technology has answered the demand for both luxury and reduced energy consumption. This new generation of on-demand hot water heaters offers quite a few advantages over traditional storage-tank varieties. These exciting systems are compact, requiring very little installation space, and can be mounted on an inside or outside wall. While you’ll never run out of hot water, tankless hot water heaters perform on demand, so there’s no standby energy losses, saving you as much as 20% from your water heating bill.

Storage-tank water heaters run 24/7 and require a constant burning pilot light. The tankless alternative activates when water flows through and turns off again when no more hot water is needed. Although they are a bigger initial investment, on-demand water heaters cost far less to operate and last over twenty years. Easily replaceable parts can extend that even further, and they are typically protected by much longer warranty coverage. They can prove even more cost-effective because of local tax credits and utility rebates, and quickly pay for themselves through energy savings.

As an alternative to storage tank models, tankless or instantaneous hot water heaters provide fresh, clean water that hasn’t absorbed rust and other potential contaminants during standby in the tank. And because there is no tank, there’s no fear of flooding due to a faulty tank.

Deljo Heating, Cooling & Plumbing offers a wide variety of tankless models for replacement or new construction projects. Our licensed technicians will provide the expertise and quality workmanship to get your water heater up and running and keep it working smoothly for years to come. No more waiting for the water to heat up. No more running out of hot water. No more big ugly tanks. You’ll enjoy endless hot showers at a significantly reduced cost.

This was my first time as a Deljo customer, and I was very pleased. My technician, Giovanni, was very thorough and diligent. He serviced my furnace and identified a faulty sensor that was causing the unit to shut itself down. Deljo ordered the part, and Giovanni replaced it a few days later. Overall, the team at Deljo was great. The dispatcher kept me informed about Giovanni’s arrival time, and the supervisor assisted Giovanni when he was diagnosing the problem with the furnace. I highly recommend Deljo.

I’ve used Deljo for over 10 years now and they always do a good job. Izzy was the technician for this visit and he did an excellent job with my winter maintenance on my multiple units in the household. He also addressed an issue while cleaning the furnace blower wheel. His communication was clear and concise with what he planned to do to address the issue quickly. He was confident and I had 0 concerns or questions. Great job Izzy!

Paul was great! Arrived on time and completed maintenance on my humidifier, tankless water heater, and two furnaces. All work was performed under my Gold Star maintenance program, so all maintenance charges were covered. Paul did provide a few proposals for additional services on furnace & tankless water heater, but those were emailed to me for further consideration. Paul was friendly, knowledgeable, and answered all my questions.

Gabe did an excellent job with our annual service visit. He arrived in the early part of our service window, was friendly and knowledgeable, and got the work done in a very reasonable amount of time. I have great confidence in Deljo, and am a long-time customer.

I’ve been using Deljo for 20 years for HVAC but now venture into enlisting their plumbing services. Bashar was very courteous, efficient & informative, and I’d definitely request him again for the next plumbing job. Great experience!

Working with Deljo is always a good experience, and today’s appointment with Izzy was no different. He was able to come early which actually worked better with our schedules, but called me ahead of time to make sure that was okay. He was friendly and knowledgeable when he explained the work he had done during his visit and our options for fixes. He was also able to schedule a quote appointment for us while he was still here. We would highly recommend working with Izzy and the Deljo team!

Drew performed the seasonal maintenance on my AC. It needed some repairs and updates and he was able to fix everything at the same appointment. He also noticed issues with the hot water heater and we were able to get ahead of that, as well.

I would leave six out of five stars if I could! My technician Jorge went above and beyond on his service. There was buildup in the rental property’s toilet from the previous tenant. One maintenance person did a surface level job of cleaning but did not fully remove the obstruction. Jorge went above and beyond and came to a solution and even explained the perpetual problems older toilet models can cause. Moving forward with this insight, I can perform my own upkeep the previous tenant did not. Thank you kindly!

We just had our new boiler installed by Jonathan and Carlos. First rate work! They arrived on time, removed the old boiler, installed the new unit, and explained the features. Both guys were pleasant. Bring on the cold this winter! We are ready thanks to the team from Deljo.
