New tankless water heater install - how did I do?

Had 2 40 Gallon hot water tanks, one of them sprung a leak so replaced both with tankless option. Home Depot had a great sale on this Rinnai Unit. Cost breakdown: $1,700 for Rinnai RX199in $65 for Tool Rental for 2 inch core drill and bit $910 for gas vents, copper, pipe wrenches, etc $1,050 gas reroute from 1/2 to 3/5 - this was subbed out to a gas fitter. Total: $3,725 Canadian I called around to get a quotes to just to fine install, and I was getting $4,000 + to just do the install. Highway robbery, and I learnt some valuable skills. I do plan to direct vent both the furnace and water heater but this is just temporary for now. We have plenty of make up air for this temporary solution. Some learnings: Maybe I didn’t need to go all copper… it was a pain in the ass to work with and caused the project take longer. But it does look nicer. Anyways provide suggestions please! submitted by /u/therealop1 [link] [comments]
