Trane vs Rheem electric heat pump split systems
Comments (6)The XL15i is Trane's highest efficiency single stage system and a very nice unit overall. In your case, for a new build, your primary focuses should be proper equipment/ductwork sizing and a quality installation. A properly designed system with good ductwork will help ensure year-round comfort. A 2-stage, variable speed system is an upgrade. The 2-stage system will provide better comfort throughout the home with longer runtimes (hence the need for a properly sized system, single or 2-stage) and therefore more dehumidification. I recommend a variable speed indoor air handler regardless of whether you choose the XL15i, XL16i or XL20i heat pumps (or other). While their summer dehumidification benefits may not be as important to you, one of the main advantages is the blower's ability to maintain a constant cfm (airflow) across varying duct conditions. This means that if the ductwork is less than adequately designed, or if your filter gets dirty and total system pressure drop increases, your airflow won't decrease and the motor will work harder (increase rpm) to meet the required airflow (up to a point, typically 1" external static pressure). This protects the equipment and maximizes performance and efficiency. I would first get a full load calculation (Manual J) to determine equipment sizing, followed by proper ductwork sizing (Manual J). Once you know where you stand, you can make a better decision on equipment selection. If you cover the right bases in terms of system design and installation, you should be comfortable regardless of which type of outdoor unit you choose to install. The XL16i Trane typically runs around 75% capacity on low stage, whereas the XL20i typically runs around 50% capacity on low stage for a greater split. If you decide on a 2-stage system I would look strongly at the XL20i (the system I chose my for home). The dual compressors are outstanding for part-load conditions, dehumidification, and more even temperatures throughout the home....See MoreWhat coil should be used in this rheem mod/ 2 s heat pump set up?
Comments (3)That was the ideal combo I found when looking the furnace and air conditioner you spec'd. The mod is a great furnace for the best indoor comfort is sized properly, but you're right that those numbers aren't fantastic on the heat pump. Though the 8.7 HSPF is what matters in heating, and that's not too bad. I'm assuming in Canada you don't use too much A/C? What are the requirements for the rebate in your area? The Amana should be an okay system. If looking for a good system for indoor comfort abilities, I suggest you do some research online at Carrier's Infinity system. If you use another brand--and there are many good brands out there, including Rheem, Trane, Lennox, and others--I suggest the VisionPRO IAQ thermostat from Honeywell to control the dual fuel setup. Hope this helps. You have to do lots of research with HVAC to get the best system, but it's worth it in the long run....See MoreAdvice needed from pros regarding replacing heat pump
Comments (13)Thanks to everyone for your input. Based on the feedback from the pros so far, I see that next steps are as listed below. Please let me know if I've misunderstood or missed anything: 1 - Ask dealer to provide, in writing, load calculation support for a 2.5 vs 3 ton system 2 - Ask dealer to provide, in writing, that existing ductwork (both supply and return) is sized correctly to handle the additional CFMs provided load calculation indicates going up in size to a 3 ton condenser. 3 - Ask dealer to provide, in writing, that existing lineset is sized properly to manufacturer spec and ask dealer to warranty any future issues with lineset (critical parts are connections at each end) $1000 to replace is not advisable unless existing lineset is not properly sized. 4 - Get additional quotes on equipment noted in proposal #1 from other Carrier dealers (along with load calcs). Current dealer pricing is very high. Remove Greenspeed model 25VNA036A003 from scope given we have a gas furnace for the first floor (this is overkill) 5 - Existing proposal for backup heat model FC-2901N09 is satisfactory (9KW that is field convertible to 3 phase) Ask dealer to install staged heat strips and specify in proposal. 6 - Continue to use current 4 ton central A/C until it dies. Not necessary to replace at this juncture. 7 - Discuss lock out temperatures with installer to ensure proper energy usage. Some additional comments/concerns: @tigerdunes - in response to your last post, we are running emergency heat strip intermittently for heat. I have been turning the fan on upstairs to draw heat from the first floor furnace to keep temperature comfortable on second floor (around 68F) Thankfully, there hasn't been a need to keep emergency heat on constantly. @tigerdunes - thank you for suggesting additional equipment. In your opinion, is the incremental cost of the two-stage Infinity 25HNB636A003 (proposal #1) worth the investment vs. the lower priced systems you suggested? I'm trying to make the best cost/benefit decision since we do not have any plans to move from this home. If it were your home, what equipment would you choose? @mike_home - you noted early on that the proposal pricing for #1 seemed high @ approx $7K. Is there a price range that is more reasonsable for a 3 ton system provided everything else remained constant - same backup heat, infinity controller, using existing lineset? What about a 2.5 ton system? (i.e. $5-6K for 2.5 system is fair, an additional $500-$800 for a 3 ton system, etc) @mike_home - you recommended getting a 4 inch media filter. Dealer proposed upgrade to a Aprilaire 2210/2410 Air Cleaner for $300. Is this worth the additional investment or do you have another suggestion? @ryanhughes/tigerdunes/all - you indicated the existing VP 8320s could be reprogrammed and used. Since they are full touch screen models that appear superior to the SYSTXCCUID01-V Infinity controller proposed which isn't a touchscreen, I was curious to the advantages of replacing vs. using the existing ? What are the drawbacks? I'm very pragmatic about changing my filters every 3 months so I don't need a controller telling me to do so if that's the only advantage. @ALL - Should I only pursue Carrier dealers at this juncture for quotes on equipment? Since I have multi-speed Carrier 59TP5 Performance Series 95 gas furnace, I am assuming you all are recommending that I do not pursue Trane/Lennox or another manufacturer as it would create a mismatched system? This was the one point I didn't hear a lot of feedback on other than the Trane having true electronic demand defrost. Again, MANY THANKS to all of you for the invaluable advice....See MoreAssistance Needed on Replacement Heat Pumps
Comments (17)I could be wrong, but I thought I watched at least one project where the local historical society had to approve some exterior work. I can't say even for those projects if replicating historical windows was involved, so you may be right. I do remember one episode where the old windows were taken out and painstakingly rebuilt. They were probably tighter, but still a single pane of glass. I would think you could make a reasonable copy of an old double hung window with a double pane of glass. One big problem is as the house settles the frame becomes crooked and the window can't close properly. It is probably not such a big problem in Florida, but it is for the cold winters of New England....See Moretigerdunes
