Change order-adding an instant hot
Comments (8)Terminology matters here. Are you talking something like the Insinkerator Instant Hot tank that dispenses hot water for beverages. $160 is the lowest ugliest chrome and black one available if that's the case. If you want to get something attractive, you'll need to be in the $250-$700 range. Plus the needed extra dedicated electrical supply line and extra hole in your countertop. $1000 is not at all out of line for adding something like that. If you are talking about a small tanked (or tankless) hot water heater designed to get you quicker hot water at your sink tap, that $160 gets you almost nothing decent and usable there as well. A better choice would be a recirculating pump on a motion sensor. Yes, you'd be looking at $500-$1000 for that convenience as well by the time the builder ended up with his markup on it....See Moretankless vs high recovery tank water heater for 4200 sq rancher
Comments (10)Be careful with the first hour ratings. On a 100 gal tank you will get about 70-75 gallons of hot on that first load. You then get the balance of the first hr rating over that first hr. For the kind of lay-out you suggest I think you should split the house up into two systems and try to centralize each tank to its load. That minimized pipe losses with the recirc, and yours will be substantial. The very best recirc system is the Metlund Design system. It complies best with all the new Title 24 regs. You will need 3/4" insulation on your hot piping. Again T24. Be very careful with the pex sizing. I re-piped with Uponor and the brass fitting here in the Foothills of N CA. There is a bushing affect on the fittings. The ID of 1/2" is 3/8, 3/4=9/16 and 1" is 13/16. It does make a difference. I have a couple faucets I was surprised how poor the pressure is on my current well 40-60 psi set-up. I had intended to go to a constant pressure well pump but now will definitely do so. Everything is good about the 50 psi range. Not so at 40# I am a fan of tankless. I represented a major manuf of tankless for 20 yrs. As far as your suggested products I will only suggest that you avoid Bosch. They, imho, do not have the right technology. Your first step regardless of what you do for equipment is a thorough water test. Manuf of tankless have to list annual cleanings for maintenance, but I had one unit for 12 years and never touched it. It was a pre-production model and I had to replace it prior to selling the house. I cut it in half and it was as clean as a whistle. Many of your plumbing questions and answers begin with the compete water test. Tankless (2) could handle your loads until you bring the tubs into play. They represent a massive load, even for your Vertex's. To handle your tub flows you should have two units on each side of the house. The thing about the tankless is they will each make your 7 or so gpm 24 hrs per day, but 135/7=about a 18-20 min fill. Will you wait that long for your bath. I have a bath fill controller on my tub. I set it at 104 and 35 gal (the vol of my tub) and it will deliver 35 gal of 104* water and shut off the hot and beep to tell me my bath is ready. Pretty cool actually. Your shower should be okay with one tankless, but your shower head(s) must fall within the flow capacity of the water heater. I can go on and on with this topic. Get your water tested and report back. That should be step one regardless of what your are doing....See MoreTank Water Heater vs. Tankless Water Heater
Comments (4)Guys if you read the post, the reason the tank water heater was so expensive was due to the construction required to get his house up to code. I personally like my tank heater. If your changing from a tank to tankless there is alot of work to do. Moving water lines, moving gas lines (possibly upgrading gas line size too) and running a new intake/exhaust if using gas, upgrading the main service amps if using electric. Some things to consider Tank Heater Pros Costs less to replace in the future Easier to maintain (Tank water heaters are easy to flush out every year) Easier to install (dont have to upgrade gas line or main service amps) Gas water heater will still operate in power outage (electric will still have some hot water to use for a while till power kicks back on). Cons Not as efficient as tankless No Tax Credits Hot water limited by FHR (first hour rating) Tankless Heater Pros Unlimited hot water More efficient Saves space Cons Will cost more in the future to replace (there is no guarantee the tankless will last longer than a tank version, the heat exchanger can go bad and that is the most expensive part of the tankless) , Harder to maintain (you need to try to clean those tankless heaters out every year with a descaler so they stay working efficiently) Harder to install (upgrade gas line or main service amps) Tankless heaters have a limited throughoutput. While it is unlimited hot water, it can only supply so many gallons of hot water at a time Will not operate in a power outage. A tankless water heater is controlled by electronics whether the heater is gas or electric does not matter. Requires minimum gallons per minute from city water supply, some people have not been able to install due to that problem. Consumer reports note that users complain of inconsistant water temperatures. http://www.consumerreports.org/cro/appliances/heating-cooling-and-air/water-heaters/tankless-water-heaters/overview/tankless-water-heaters-ov.htm Another good site to look at: http://www.waterheaterrescue.com/pages/WHRpages/English/Longevity/tankless-water-heaters.html...See MoreTankless electric hot water heater q's... replacing tank...

Comments (21)We installed a gas tankless in 2013. No problems at all. The size & number needed was decided by the company installing our Rinnae brand, which was purchased through Ferguson. Our choice was determined by space considerations. As mentioned, it is helpful to place it close to your kitchen/bathrooms. Our location was not ideal. The size of the gas line had to be increased, adding to the cost. We have no regrets, but moving yours to the garage sounds like a much cheaper option. As previously mentioned, it does not work in a power disruption. It also did not improve the look of the laundry room. There are pipes running above & below. I wish I had known what the finished installation would look like, as I would have changed the placement....See Morezl700
