Davidro1, Hehe, thanks, and I like your "style". The 80 gallon could be mostly fine but most setups have 4 body sprays not 8 and also with air bath, I feel we will need backup if we ever wabt to take bath & shower back to back. Plus kids baths etc. My gc who does plumbing may not be the ultimate expert in plumbing but is probably better then most avg. Plumbers and may not be up on everything buy hes pretty smart and accurate. He was good enoigj to do a maze of copper piping snd loops for the dtv with 8 body sprays, a shower head and hand held plus still room to do a manual controles roughin valve piped to another wall supply elbow (as a back up if dtv ever down) I like a lot of ppl on these forums started small and ended uo doing mlre then i intended. I woukd have been fine with 4 body sprays but couldnt cancel/return the 4 off wall sprays and really wabted the kohker water tiles because they are flush so also got 4 of those for the sides. The bathroom project has been a nightmare because of a bad middleman contractor who held money & matetials plus made mistakes aming other probkems and huge delays. I just want to get done and resume my life with my family. Its just if this is our forever house, my wife said if you are going to do it, donit right. I told her no to body sprays and now end up with 8. The kohler dtv was also not intended but I went with it to save ne from buying more valves and trims to control everything and i got good price on the valve and interface. Of course the space in wall was tight so couldnt use the more expensive pex so had to use copper which while cheaper tool my gc/plumber 4 days ti do paid by the hour. Anyway, he said his friend did a tankless, that its great and he can install no problem. He suggests having it feed just the master bath and will be plenty. I think my gas lines will be sufficient cus they areinly 5 yrs old and pretty thick yellow pvc gas lines. No idea where hed install it and how it would tie into just the bathroom but if it works out and the bathroom ever gets done and all wotks ok will be a miracle at this point. Gas lines are in basement under the side of the house where masterbathroom is and water softener (we brought with us from old house) and water shutoff is on the other side of the basement under side of the house my daughters bathroom is which is probably why hers has the best water pressure. So hopefully 1 medium/large tankless for just master bath will be enough. Still have to pick and find one. As for water pressure, ive been worried about that from the start. We dont need or neccesary love super high water pressure but as long as we have volume control (which dtv does and even the manual handheld i put on a supply elbiw with vc) then its good to have the power available. And bodysprays are useless if the water just trickles out (ive seen bad installs) I guess i just hoped the dtv would magically boost the water pressure. But I fear a pressure booster might be neccesary but I have no clue where ti get one or how its installed. I fear it would have already had to be put in with the pipong which now has tile backerboard sheet rock covering it all. Maybe the lressure booster can be put in basement with the tankless, both feeding just the master bath? I also have the major stress of getting a new tub last minute now that my order was canceled by the manufac believe it or not due to a most ridiculous and border line illegal debacle of which we wefe the victim of (see Jason hydrotherapy thread) And depending what tub we get, may need to put an access panel in the laundry room ceiling below tub to access a second and left sided blower. It never ends, the expense and the stress that is. Add to that a scammings middleman contractor who currently has our money and some materials but hasnt even used our money to get the rest of the tiles yet. Oh and because of him owing the gra ite fabricator money we had tonuse a different fabricator for the seconf half of the stone for the jov so its not going to match. Anyway, we'll keep this thread about Kohler dtv and the water heater and water pressure pump needs therein.

Thank you for the feedback.. FYI - These are not heat Pumps - Strictly straight A/C units w heat strips. The old unit ran fine in its earlier years and in its later years was nursed along and did not cool as well. I believe 3 tons will work fine as the old unit did the job in the early years and had to work in the summer when the sun came in during the late PM in the later years. There is a lot of heat that scomes through those windows in the summer. The efficiencies in todays units probably deliver much better cooling than I was getting.. Especially if they are sealed. I do have a second unit taking care of the living quarters and the Den area which are alongside this main room - when I sealed the unit 2 yrs ago - what a difference.. Another proposal came in today with 2 different A/C units w strips and 2 different Heat Pump quotes from the current Lennox servce provider who services the equipment. 1. Lennox XC14-036 Condenser unit (14.20 SEER/12.00 EER) using the new 410A refrigerant · Lennox CBX26UH36 Fan Coil with Thermostatic Expansion Valve · Lennox ECB26-10CB Heat Strip with circuit breaker · Manufactures warranty Condenser 10 year compressor & 10 year parts, Fan Coil 10 year - $6986.00 Installed w existing Thermostat 2.· Amana ASX14-036 Condenser unit (13.50 SEER/11.80 EER) using the new 410A refrigerant · Amana ARPF363616 Fan Coil with Flow-rater Valve · Amana HKR-10C Heat Strip with circuit breaker · Manufactures warranty Condenser Life Time compressor & 10 year parts, Fan Coil 10 year $7080.00 Installed 3. · Amana ASZ14-036 Heat Pump unit (15.00 SEER/13.00 EER) using the new 410A refrigerant · Amana ASPF303616 Fan Coil with Flow-rater Valve · Amana HKR-10C Heat Strip with circuit breaker · Manufactures warranty Condenser Life Time compressor & 10 year parts, Fan Coil 10 year $8168 installed - and qualifies for Tax credit 4. · Amana ASZ16-036 2- Stage Heat Pump unit (16.00 SEER/12.50 EER) using the new 410A refrigerant · Amana AEPF30361A Fan Coil with Flow-rater Valve · Amana HKR-10C Heat Strip with circuit breaker · Manufactures warranty Condenser Life Time compressor & 10 year parts, Fan Coil 10 year $ 9,442.00 Installed SEERs look a little low compared to the earlier quotes.. I am not familiar w Heat pumps only straight A/c and Heat strip units.. I feel that running that compressor unit in the winter just creates wear..That is why I'm slanted toward heat strips. Can one get a manual J from an independent source or does it have to be a contractor? I hear they are some work to work up and obviously I will pay for it. How much are they. If you have suggestions on specific units / condensor / air handler combinations I'd be happy to check them out as well. This is a big expense and i want to do this right. Thanks

I am not the Ruud expert, but it appears to be a basic single stage system. Here is your Proposal 6: 2-stage, variable speed Carrier Furnace 59TN6080-14 (same as 5) 2-stage Carrier AC 24ANB736 Carrier evaporator coil CNPV3717 Infinity thermostat Comparing Carrier Proposal 6 vs. the Rudd system 2-stage 60KBTU vs. single stage 75KBTU (75K may be oversized) 2-stage 3 ton condenser vs. single stage 2.5 condenser 17 SEER (need to check) vs. 14.5 SEER Infinity thermostat vs. unknown thermostat The Carrier system is superior. You can get an equivalent Rudd system but it will cost more. I would spend the extra money on a variable speed furnace and a 2-stage condenser.

I tried getting quotes for the XR15 model but was told it is being phased out, so I got quotes for the XR 14 and XR 16 instead. New Quote #1: $6950 for a Trane XR16 (2 ton) up to 16 SEER Single Stage R410A Heat Pump (Model# 4TWR6024D1000A), Hyperion XL (2.5 ton) variable speed blower motor air handler (Model# TAM7A0B30H21SD), Trane 10K Supplementary Electric heater for air handler installation (Model# BAYEVAC10BK1BA), and Sen-si Wifi Programable thermostat (Model# 1F86U-42WF -https://sensicomfort.com) New Quote #2: $6150 for a Trane XR14 (2 ton) up to 14.5 SEER Single Stage R410A Heat Pump, Hyperion XL (2.5 ton) variable speed blower motor air handler (Model# TAM7A0B30H21SD), Trane 10K Supplementary Electric heater for air handler installation (Model# BAYEVAC10BK1BA), and Sen-si Wifi Programable thermostat (Model# 1F86U-42WF - https://sensicomfort.com) Is there a big difference between the XR14 and XR16? Also, for $300 more, I can upgrade the thermostat from the Sensi to Trane's ComfortLinkTM XL850 model. Is it worth it? The digital display looks cool.
