Have issues with slow hot water or someone takes a shower or runs washing machine and no hot water to go around the rest of the house? Incredibly easy to install, and can power through junction straight from the water heater and pipe into he water heater with just adding a 3/4" Tre and two short nipples.
I would be happy to install if interested and not to far a drive on the weekend. Can use of a tankless as well but much more efficient on a tanked water heater. Also useful if you have an outbuilding or shop that needs hot water.
I installed a tankless on my home and ended up not going this route but I've used them for years and seriously 3x the speed of getting the water to far rooms and spreading it out for even use.
Give me a shout if you have any questions. I work alot so can text if I miss call and I'll get back to you soon as I see it
