Frequently Asked Questions

How do boilers work?

The boiler heats a liquid and the heated fluid is then pumped through the pipes. It enters devices like radiators, in-floor heating loops, etc. to help keep your home comfortable and heated. There are also some combination boilers that may help take care of your home’s domestic water usage as well.

You’ll need to determine if your home’s heating system uses pipes and radiators instead of vents. If you have pipes and radiators, your home has a hydronic heating system, meaning that you have a boiler. Feel free to contact us if you are still having questions about this and one of our team members will be in touch!
Boilers use heated water and a series of pipes to efficiently pump heat throughout your home. Furnaces heat the air that is distributed throughout the home via a duct system and a blower motor.
Our team at Deljo Heating & Cooling makes it easy to find the right boiler for your needs. One of our team members will provide you with an array of different options that fit your criteria and help you solidify the best choice for you.
We recommend that your boiler is serviced at least once a year to ensure it is working at maximum efficiency and that there are no red flags. This will reduce your need for boiler repair in Chicago in the future.
Radiators may be used to also cool your home, however, boilers don’t have the specific functionality to cool your home. If water were used in your home’s radiator system, it would result in corrosion, humidity, condensation and other frustrating issues that you wouldn’t want to tackle.

We’ve been using Deljo for several years and have had a great experience with them. They’re prompt, reliable, and trustworthy. The technicians (David was the most recent) have been great.

Ari Telisman Chicago IL.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
