The customer support at Eco-King is top notch!

Review for Eco-King Supreme Residential On-Demand Boiler & Combi Boiler

Date: October 29, 2021Written by: Mike RivetFrom: , British Columbia, Canada

I installed an Eco-King C140 in November 2016. The system has had no issues until recently. I would occasionally get error code 8, flame fail 6 times. I had never witnessed the boiler going into this lockout before. I have done numerous auto calibrations and all the maintenance tips in the Eco-King YouTube video library. I am a gas fitter of 20 years but I was stumped. Reached out to Eco-King and Chad Euverman suggested that the symptom I described happens when the gas mix is either too lean or too rich. He recommended to run a gas combustion analyzer to confirm. I did so, as well as manual calibration last night. It turns out the boiler was just fine and problem-free, but the CO2 was low across the board! So far so good, no flame outs. Time will tell but I am confident that the issue is resolved. Thank you very much for all your help. The customer support at Eco-King is top notch!


Great product

Review for Eco-King High Efficient Electric Hot Water Tank

Date: October 14, 2021Written by: Lee Carter Plumbing ltdFrom: Whistler BC, British Columbia, Canada

We have fitted around 10 of these units so far without any issues. Its nice to be able to offer our customers a far superior product to the usual hot water tanks available.
Great customer care from Eco King also.


Not only because of a great product but an awesome team!

Review for Eco-King Supreme Residential On-Demand Boiler & Combi Boiler

Date: July 1, 2021Written by: Russel JosephFrom: Toronto, Ontario, Canada

I want to say that you’re help desk for trouble shooting was a great experience. I called late in the day around 2pm and talked with Bill first who was very good and informative. I had a couple of challenging questions on my customers unit I was having trouble with that he was helping me with.

Eventually he had Chad then talk with me on the system and roughly around 4pm maybe a little later we were able to correct all the issues. My customer was greatly appreciative to have her system corrected after suffering for over a few months and multiple visits from other techs.

During the call neither Bill or Chad rushed the call with me and I sensed they would have stayed on the phone all night to help me correct the system. This was a great experience and will be suggesting you’re product to my customers going forward.

Not only because of a great product but an awesome team!

I've been using Eco-King combination boilers and system boilers for a few years now because they are a quality product. Coming from the UK boilers background, we're used to boilers being the main heat source so I'm used to the concept Also Chad is really knowledgeable and friendly and a pleasure to de with
