Very happy with the customer service, Maxime was professional, easy to reach and answered my questions. There was damage to the boiler cabinet from the shipping company and it was rectified quickly.
I’m still finishing my build do install won’t be happening for several months.
Excellent seller. Products arrived really fast, package was cushioned, products as described with very good price and on top of all I was able to buy from a company in my province. Congratulations for the amazing service. I gave your information to a friend and I hope next time I need someting, to find it at your company.
Easy to install and seams really solid. Looks easy to change the element if it ever fails in the future or change it to a different size if I missed on my calculations. Has been running my workshop heat for a week now and seems to be really efficient.
