The Next Generation of Tankless Water Heaters.

For decades, engineers researched ways to decrease energy use and maximize efficiency. Now, installation of a tankless hot water heater can offer the very best of the modern energy revolution with multiple options designed to decrease your energy requirements while still delivering hot water on demand, year round.

Ottawa Homeowners Never Have To Run Out Of Hot Water

Have you ever had situations where you’ve run out of hot water? Especially on a cold Ottawa day, it can be miserable. Typical water heaters hold a few gallons of water, and you pay to keep it hot, around the clock, whether you use it or not. Tankless water heaters only heat the water you need, when you need it – saving you money (according to Natural Resources Canada).

The Installation and Maintenance of Your Tankless Water Heater makes a big difference in how the unit performs.

The vast majority of handymen and technicians lack the expertise to install the next generation of tankless water heating equipment. When unqualified technicians handle the installation, the result is a poorly installed, improperly functioning investment that fails to deliver the anticipated savings and convenience.

 Trustindex verifies that the original source of the review is Google. JD Swallow installed a new gas-fired hot water heater for us. Andrew G. and Kevin F. were on time, friendly, and professional. They were careful to lay down mats to protect the floors as they moved the old water heater out and the new one in. They tidied as they worked, and the area was spotless upon completion of the installation. Another job well done by JD Swallow Heating & Cooling!

 Trustindex verifies that the original source of the review is Google. I recently contracted JD Swalllow to replace my leaky combi-core hot water heater. JDS were up front about their process and their pricing was very competitive which made my decision to hire them very easy (plus, they came highly recommended).  Thank you to the team - Jeremy, Germane, Jithin and Alex - for making the best of  returning my old tank and then installing the new one in a very tight space. And thank you to André as well who returned the next day to finalize a few things requiring his expertise. He also provided me with a lot of information on extending the life of my new HWH. I will keep using JD Swallow in the future and recommend them to anyone who asks.

They worked efficiently throughout the house and were very respectful of the areas they were working in.  What was even more impressive, was the way they interacted with my two dogs.  Would highly recommend!
