I'm switching from tank to Tankless (likely Noritz NRCR111dv). It will be mounted in the attic where current tank is. Anyy recomendations on where to mount the controller. It can o next to unit ut wonder if it's better to install in the living space somewhere? Looking for ideas. I'm thinking a...

Hey all, Do you think I descale the entire hot water system - tankless heater and pipes - by running CLR solution or Vinegar through it using the circulatory pump? In this configuration the circulatory pump would suck CLR solution through all the pipes and the heater from a bucket on the...

Let me start by saying hello, and thank you in advance for all who read and attempt to offer advice. We have a Richmond 18kW electric tankless. It is only around 18 months old, and it's been around 12 months since I last successfully flushed it. Now, it won't even flush. When running, the...

Just had a tankless water heater installed. Seems like it could be a little cleaner and tidy than this! Such a mess and not too appealing to look at it. I'm not a plumber, but wanted a professional's take on it? Am I being too anal about it? Thanks for the feedback in advance. C

Another one of the millions affected by the freeze down here in Texas. Have not been able to get a plumber out and cannot get moved back into our house until we get this issue repaired. We drained all the water lines before the freeze so we were fortunate to avoid any broken pipes. However, we...

I'm among the millions of folks impacted by the "big chill" in Texas and could use some help. I have a tankless Navien 240. One of the fittings broke during the freeze, it's leaking water and is the reason I'm getting error code E438 (I believe) and, more importantly, the reason we haven't had...

Hello! New here, not sure if this is the right place to post. We just moved into a home with an older tankless water heater made by a brand that doesn't exist anymore. A few days back it stopped working and starting giving an error message of 11, with an occasional 12 thrown in. The company...

Hey everyone this is my first post, and I usually don’t resort to forums to ask for help but I just can not figure out my issue. I have a Bosch AQ 125 - BNG tankless water heater. Which works great. Except for when we try to take showers. I have read about the “cold water sandwhich” but that...

Tankless Hot Water Heater: A lot of development of this product since it came out in the US market. Any general thoughts about tankless vs gas fired hot water heater? Do you think the cost is worth it? Maintenance issues/concerns? Other thoughts? Thank you.

Flushed ecosmart27 to descale it. After 30 min the vinegar was blue (normal, I should've stopped here). After 90 min the solution was clearer but the bucket was covered in grimy, grey, greasy coating (see pic). Dry, it's grey soot that smells metallic. Any ideas to clean this stuff out of...

Hoping someone can help troubleshoot an odd situation that I haven't been able to answer via many Google searches! The hot water in our primary kitchen sink has begun working inconsistently. It may provide hot water immediately and then get cold and take many many minutes to get hot again. Or...

could a bad flow sensor cause the unit to make a banging noise when the water is turned off at the sink?

I bought a home and the hot water tank was rusted out so I decided to install a tankless water heater. I installed it and it works but after about 3 months i started to hear a loud banging noise when the water was in use. I researched it and most people said it was jackhammering, i think that...

Hello, our Eemax EX280T2T water heater recently sprang a leak. We're hoping to replace it but the reviews for the same unit are not that great and we'd like a solid, reliable replacement, but we'd also prefer to do minimal rewiring and plumbing work. Obviously we already have the three circuit...

Hi All, I'm buying a home built in 2013 that uses a tankless Rinnai water heater. I know the current owner's never flushed or serviced the unit, and I'm trying to decide the best course of action. 1) The seller can hire a plumber - probably the cheapest they can find - to service the unit...

(short lead in... had an addition build a couple years back and a Rheem ECO200 9.5 GPM tankless unit installed - addition is 1 bth, kitchen and laundry - with the anticipation of tying it into the main section at some point) Question: what is the best practice to do so? Would it be best to run...

I need a new water heater and I'm considering a tankless (on-demand) due to the long term cost/energy savings and space savings. A local plumber has recommended against it due to the water in town. I think he said the water has chloramine which causes problems with the tankless system. It's also...
