Why are top take offs worse than side take offs? Is this true for round and rectangular ducts?

I have a regular generator is there something I can just plug in the 30 amp receptacle that will lower the THD.

Which type of motor suitable for VFD? (Induction M, Sychronous M, Universal M)

Great

What's the system starting with a Z mentioned?

Good information while planning to design and install an ERV system

Mine eir to weater

My heating comes on night time it on anto

Is it best to leave it on anto

what is the model # for the forced air, Scenario at 49:47 point of the video

Let me get this straight, after recognizing the need for housing and the need to reform labor laws to expand economic opportunity this is what the state came to? I know Governor Scott did not approve of this measure and many more like the institute for justice of the federal trade commission has opposed occupational regulation, the issue is with little risks to consumers from what has been a historically unregulated market and unregulated construction has yet to cost Vermont more than it has costed other states, so the old saying is, “if it’s not broke don’t fix it” Vermont is doing better than many states and has worked fine without the regulation, and like the governor added this all come at a time when housing is exponentially increasing in costs to average citizens and the increase in regulation can risk exasperating that issue, or as maines Governor said, “it is not prudent policy to raise costs and regulations for builders in a time when they are most needed” in mine and the other governors opinion this is just regulatory overkill and rent seeking by the state or board of contractors themselves *tsk tsk

Thank you for the informative video. I just have one question, how unequal flow exactly save energy if it doesn't go through the water heater , because when the water heater has preheated water, it's going to do less work means less energy, which means more saving , but if it doesn't go through it how exactly the energy saving is happening?

minute 14, could've added another strategy is lower heat load by air sealing and insulation

I'd like to see more discussion of *ducting*. I think if I could get hot air from the attic, that would be a major bonus.

Lots of competition now with emphasis on bacterial threat elimination. Where in this video is that discussed?

Are there any updates/ newer videos including the new115volt models?.

Thank you.

How does the bypass valve work? Is it normally open? Normally closed? Does this valve have to be closed to do a proper flush? Rheem tech support is telling people they do not need to ensure the bypass is closed!!! Just unplug the unit and go for it...according to Rheem tech support.

There's 100 how to flush...descale...videos ...NONE tell you how to close that bypass valve. Millions of these things in service have never once been flushed correctly! 38:10 how to bypass the bypass valve.

Thanks for all the helpful information...and all the enthusiasm! Keep up the good work!

What would you say is a good switch over temperature when using a mini split heat pump with oil as backup?

I am happy to see that individual suppliers are addressing the "change over" problem from ASHP to the secondary system. As new products come out that are "universal" or independent of the heat pump brand it would be good to add to the comments for people to investigate. For example the Flair Puck Pro is one option but is best for single indoor units as each indoor unit requires a "puck". This can get quite expensive.

In this training video it states Heat Pump mode is the most efficient at “Very High” However, in the user manual it states Energy Saver mode is “Very High”, while Heat Pump mode is only “High” Taking out the recovery time factor, isn’t Heat Pump only mode by far the most efficient? I’m going to run a test, 1 month in only Heat Pump mode, followed by 1 month is Energy Saver mode, to see the real difference.

Awesome

She says “uhh..” a lot. Funny coz we’re always told not to do that with customers….

Good stuff, thanks.

Thanks for your effort and for the upload! Very interesting

I’m getting a code 34 on my rheem

Hello,what’s your preference on tank water? Anti corrosion,or water softner ? Thanks 🇺🇸🇺🇸🇺🇸🇺🇸

RHEEM, HELLO, WITH EVERY BLOGI read,,the USUAL COMPLAINT, is insufficient hot water,BUT every case a homeowner goes to the BIG BOX STORE & purchase by PRICE,NOT BY THEIR NEEDS,SO THEY CURSE THE BRAND<or ALL HEAT PUMP UNITS, , FOR ME PERSONALLY,,I WOULDbuy a STELBRON ELECTRON,they had been making them for DECADES,, before the USA,started making them, the WORLDS MOST POPULAR UNIT. THANKS 🇩🇪🇩🇪🇺🇸🇺🇸

How do you change the anode?

Excellent presentation--going to install 2 units in my home within the next month

Any input on the massive amount of Gen5 noise complaints? I'll wait a year or so until the micro chip shortage has been dealt with.

superb presentation and helpful.

The eco app should have upper and lower tank temperature. Also, if you have a recirculating system, so type of setting to have water heater work right and not a service bulletin saying you should not use pump. The hybrid water heater tech support don’t work weekends and regular electric water heater tech support is 7 day

How do I remove the code 88 permanently? Thanks.

I like to know if I can use the Hybrid water-heaters for dual purposes which means using the unit for domestic use and to heat my home with a hot water system, zones and circulation pumps? I have already the lines and in place and need to install the plate radiators, the house is well insulated.

what are the default dip switch settings to avoid the code 88 issue????

The duct adapters seem to be unavailable ? Do you have a source or link please .

The "Heat Pump Only" mode is NOT heat pump only. It will also call for electric elements to come on at the same time just like in the High Demand mode. This really sux because it loses it's efficiency when doing so. I called Rheem and they said it must be a glitch or something in the algorithm and they still have not fixed it yet. Sounds like it won't be able to be fixed with an app update either. It's gonna be a hardware issue in the control board. They need to send out new control boards to anyone who has bought one of these in the last 8-9 months or whenever the Gen 5 models came out. The Generator 4 models didn't have this problem.

i've operated my 80gal hybrid for 3 years now with a recirc pump and i have some feedback for fine tuning these modes. i'm thinking update the firmware if possible or introduce some new modes that combine high demand with energy saving (they are similar already) but there is room for improvement, who should i contact?

Does the unit have freeze protection I'm in Texas and weather does not get to bad but this year it has been below freezing we have cold water coming out but no hot water flow are the pipes frozen are do we need to do something to units we have two tankless systems

This is an excellent video overview of what has changed since my "Performance Platinum 50 Gallon Electric EcoNet Enabled Hybrid Electric Water Heater with 10 Year Limited Warranty MODEL # XE50T10HD50U1" installed in mid 2019, thank you! It's also helped me update my detailed article about hybrid water heaters accordingly, adding this video so today's buyers are much more informed.

This was a great presentation. It was the ONLY information that let me know exactly how the leaksense and leakguard worked. It was also the only information that helped me figure out why from initial power on I was getting constant false positive leak detects. The manual says NOTHING about requiring a drain pan for my particular model. I can only assume the red perimeter leak sense rope is picking up moisture from the concrete slab. This is not cool because now I will have to drain and disconnect the unit just to install a pan which I'm not even sure will solve the issue.

Do you have a video on the actual installation. I have some questions.

I had a 65 gallon unit installed in December and this presentation gave me some new information. Thanks,

Can my underserved area in San Ysidro, California qualify?
