Hello. I have two water heaters in my basement that are both at least 15 years old. One of them is occasionally pushing a little bit of water out of the "pressure" release valve (I don't have knowledge in this area so the terminology is probably incorrect). I am guessing it is time to replace the water heater and probably time to replace both. My question for anyone with knowledge in this area is whether or not I should put 2 new water heaters in or should I do tankless? Any advice would be great! We are a family of five (3 young children so the water usage isn't diminishing in the near future). Again...any advice on going tankless (what is the cost of installing one) vs replacing two water heaters would be appreciated! I will try to attach a photo of the utility room showing the setup. Thanks!
