Ordered a barrel heat exchanger and faucet with delivery. Work was completed by a professional plumber from https://drainexpress.ca/whats-clogging-your-drains-and-how-can-you-fix-them/ service. There were problems with the installation, but they were easily solved. Overall, the impressions are very good. The work was done qualitatively and on time. I will recommend you to my friends and acquaintances. Thank you very much for the work!
