Help me choose a hot water heater, recirc pum, tankless or vertex
Comments (0)We are in the process of building a house. Currently our plan includes a 75 gallon tank located in the garage. We have a 2 story home, about 4000 sq ft. 2 baths(1 is guest, used infrequently), kitchen, laundry down. 3 baths, stackable laundry center up. We are concerned about getting hot water to the other side of the house where the master bath is located. We have 4 very young children, under 8 yrs old. So not alot of simultaneous morning showers now, but that could come in a few years. Here are our options: 75 gallon w/recirc pump = $1800 two 50 gallons w/recirc pump = $1800 + $575 Tankless Rinnai (adequate for 2 showers running same time)= $1408, if we need 2 smaller system add $1442 50 Gallon Vertex On Demand = $1771 The Vertex seems to be a good option if it can provide us with enough hot water? Please give me you opinions/experience!...See Moreservice from BOTH old water heater and tankless water heater ?
Comments (4)We don't want to shut off the water when the remodel to the room is finished. We just want to switch the water source . For example after finishing the hall bath, can water coming from the water heater in the attic be switched via the remodel process to the new tankless water heater that will not be in the attic? But still will need the old water heater for rooms not yet remodeled and whose plumbing hasn't been upgraded to copper,etc. Can both water heaters be running at same time? For example keeping the master bath and the kitchen still using the water heater in the attic because plumbing will not be complete yet that routes them to tankless. So we will have both tankless not in the attic and the old water heater in the attic working at the same time but just servicing different rooms. Can we do that? I didn't specify since I'm not a plumber but I can't help thinking that main issue is that you need gas going to both water heaters and water from the outside being routed into both water heaters. Not sure if this is possible to do. Then after 6 months or a year when all rooms are remodeled and have their galvanized pipes replaced with copper, etc. and have plumbing routed to new location of tankless, the old water heater in the attic can be shut down because it won't be used....See MoreDo I go tankless water heater or wait for 75-gal gas heater?
Comments (7)We don't have much info to go on. We don't know what your needs are, what your wants are or what your budget is. All we really know is that you want gas in the event that the electricity is out. A tankless requires a small amount of electricity to operate - it would not operate if the power was out. A generator would solve that problem and provide power for other things as well. I don't completely agree with Dan, you can size a tankless to run more than one thing at a time. I sized mine so that in the coldest part of the year I could run the shower and the bathroom faucet - in the summer I can run about twice that amount. It works fine in my house, but if I had a larger family I'd go with a larger unit. There are also 50 gal Hybrid units - They store the water but have high BTU input and very high efficiency. They can produce a certain amount of continuous hot water as well. These meet the 30% tax credit requirements and vent with PVC pipe - making them cheap to install where long vent runs are needed. I have included an example - I'm not endorsing a particular brand. Note that these would not run without a small amount of electrical power. Here is a link that might be useful: State Hybrid...See MoreQuestions about Rinnai Tankless Water Heater
Comments (11)Mounting the remote outside makes absolutely no sense. The purpose of the "remote" is to allow changing the temp setting at one (or more if there are multiple remotes) of the hot water usage locations inside the house. I typically see them mounted in the master bathroom. Tankless water heaters operate at best efficiency when the setpoint is AT the desired hot water temperature for a given task and only the hot water tap is run, for showering for example. I don't have a remote but my tankless is in a broom closet in my laundry room adjacent to the kitchen so is easily accessible for adjustment. I keep it set at 103°F as the normal temp (for showering) and raise it temporarily for other tasks such as handwashing dishes or laundry. Most people run a higher setpoint for "normal" use and perhaps would lower it for showering, thus having the remote in their bathroom....See MoreSteveningen
