Observations after four years of a Tankless Water Heater

[Anonymous]

Unless you have a recirculating pump near your shower, bath, faucet, you are going to run the tap for a few minutes until you get hot water.

If you have. 4.5 GPM faucet filling your bathroom g tub, you get no pressure at other taps.

However, I can run two showers and my dishwasher or washing machine at the same time with no pressure loss.

They don’t tell you if you live in an area with hard water, expect to pay about $600 every 18 months to clean out your system.

Your water and gas bill or electric will go up as your hot water doesn’t run out.

Having a remote to turn it off with teenagers in the house who take long showers is the best option ever.

This is great. Our shower is instantly hot so we must have that recirculating pump thingie.

Didn't know about the hard water.

It keeps it operating efficiently as the clean the scale out, but it is labor intensive.

It sounds like it sucks.

I though they were supposed to be more efficient it doesn't sound like it at all.

We have had one for 12 years with none of the problems you described. We have only had it serviced once…

It takes forever for me to get warm water out to wash my hands/face. I hate it.

Time to get hot water is more dependent on how far your heater is from the point of use than the type of heater.

We put ours in the pantry right below one bathroom. I think we do have a recirculation pump to move water to the other bathroom faster too.

Still a huge fan 10 years later, although I probably should service it at some point.

We have a 75 gallon water tank and no issues. I would have liked one for space reasons but our house had no way to put one in.

Several years ago, Lowe's was running a special to have the systems removed from homes of recent buyers who hated the tankless water heater.

OP here. We love ours but wanted to share some pros and cons. For us the pros outweigh the cons.

Our tub is so big, hot water would run out before it was full.

Ground water temp takes longer to warm up. Longer in winter than summer.

But there is less incentive to take shorter showers when hot water doesn’t run out, so higher water and gas bills.

Thank you OP! It’s really helpful to know these things. We replaced out water heater a few years with a conventional one, in part because we had been told about the maintenance costs.

OP, would you tell me more about the remote? Does it work for one shower or the entire house? Teen showers here can be an hour long.

+100

Our tankless has a small recirculating chamber so we get instant hot water.
Water softener softens before water enters the tankless so none of those issues.
It runs like a champ and we never run out of hot water.

LOVE LOVE LOVE it.
