So...you add a tank to your tankless system?

Anonymous wrote:The problem with tankless last time I was considering one, is that water flow required to "turn it on" is inversely proportional to its heating capacity. So like, I have six people in my house so we need to be able to supply hot water to at least two showers and one sink at the same time. When you do that, a lot of times the flow rate from one sink won't be enough to kick the heater on. So if you want hot water to come out of your sink tap, you have to turn on another sink or a shower to get it to heat LMAO. No thank you

This sounds like FUD — if it was really a problem no one would buy them or recommend them

^^^^^ sorry, "inversely proportional" should just say "proportional"

I’ve filled inflatable hot tubs with 100 degree water twice with two different tankless heaters and it never once stopped heating.

We're switching to one next year. Unlimited hot water, space savings and we will install a carbon filter too. The life expectancy is around 16 years.

We switched over from a large tank to tankless. Wow. We were able to free a huge amount of space in the basement for storage in the process.

I love the infinite hot water. We have three teens and they can take a 30 minute shower and we never run out of hot water. We have a large tank that can handle six fixtures at the same time. So we have had the washer, dishwasher, and two showers going and never had issues.

Never having to wait to take a shower because you ran out of hot water is priceless.

Although over time, it pays for itself.

Meant to write - tankless

Agree with everything already written. We love the continuous hot water and not worrying about massive tank flood. We have 2 heaters for 6k sq ft house.

Not if it’s sized correctly.

They’re good for saving money on bills, reducing the physical footprint of water heater in basement/closet, and provides continuous hot water that would require. A very large, expensive to operate tank (much larger than standard 40-50g, which creates even more costs savings on bills).

We wanted one in our new build but were told they really are best when there isn’t the space for an extra large water tank, but greater water capacity is needed.

We just did a very large water tank (can’t remember how big, sorry - but it’s huge!) and we’ve never had any issues running out of hot water in our family of 5.

Do they have a hard time keeping up if many people want to use hot water in the house at the same time?

The main reason we got one is that we don't have to schedule who gets a shower when anymore because of continuous hot water. Additionally, I like that there is no tank of water that might flood my basement one day (happened twice in the past to me). I am not sure about your hard water question.

Enlighten me please. Also can you use them in areas with untreated hard water? How long will it last in such an area?
