So in new home construction in most cases a tankless water heater is only going to add about maybe one to two thousand dollars to the price of the house over tank so mu mortgage that equates to basically pennies now what am I getting for that extra money on that new house by putting in a gas fire techs water heater you’re getting a 20 year life expectancy not 10 so if you’re going to be in that house any length of time 10 years from now you’ve got to figure you’re probably going to replace that tank the other thing is of course endless hot water.
You can’t run these things out no matter what to do they’re not burning gas when you’re not home and you’re not running hot water they just sit still so there’s a tremendous advantage to having tankless over tank and new construction I will say it’s a no-brainer there’s no reason to put a tank in a house at new construction anywhere in the United States period you can always get a tankless in easier than the tank that take up less space as well with a little bit of thought there’s no reason to have a new home without tankless water heater retrofits a little bit different not everybody is going to want to spend the money not everyone should spend the money all right kind of back let’s go back a minute to an existing home if you know you’re going to be moving out of the house in a couple years and you have a tank that’s failed there’s no point spending three to four thousand dollars for a product that you’re not going to really be able to get a benefit out of if you’re going to be moving in a couple years put a tank back in no big deal so I hope that’s helped you new construction and retrofit on gas tankless and in the final segment I want to talk to you about the electric tankless water heaters.
If one of those might be right for you electric tankless water heaters this is where things start getting a little trickier alright and a lot of its going to have to do with where you are in the country what your incoming water temperatures aren’t those sort of things there are some very good electric tankless water heaters on the market now and there’s some that appeared junk home centers I’m sorry forget about it you do not want one of those water heaters right don’t even think about it that would be my air conditioning or rather my heating system kick it in now when you’re dealing with a whole house electric tankless one thing you want to remember is none of them control flow most of the gas water heaters will control the flow so you can’t overshoot them with an electric sizing is very important because if you undersized the water heater and flow more water through it then it can heat you’re going to get a cooler temperature water on the outlet side in other words it won’t be able to keep up.
If you float too much water so you need to make sure that the size is going to be appropriate for your job and my area most houses will do very good with a 28 kW or a 32 kW electric tankless water heater two and a half baths three and a half bath home depending on how you’re going to use it those can work fine if you don’t have the gas that could be a good option for you you want to be careful to choose an electric tankless water heater that has a couple of features you do not want one that slams the elements on at a high rate and stages them like a four element system slams on the first element at 40 amps Ram that’s a big hit to your panel it’s going to cause the lights to flicker and it’s going to cause your energy bill to flicker up you want to look for a water heater that’s going to turn on all four elements in that four chamber model at the same time at six to seven amps and ramp up smoothly from there it’s easier on your electrical panel it’s easier on your bill won’t dim your lights and it’s going to give you a lot better temperature control too so instead of bouncing an element on and off during a low flow at 40 amps overheating the water and then under heating the water giving you temperature swings it’s going to do a much better job right now the only one.
I’m aware of that does that is company called szybko very good electric tankless water here you also want one that’s going to have elements that if they go bad are going to be relatively easy and relatively inexpensive to replace that particular model again has screwin elements very similar to the ones that are on a tank water heater actually made by a major tech water heater element manufacturer so they’re relatively easy to get and they’re not that expensive everything breaks eventually that’s a very good serviceable model so again with the electrics you really need to know how they operate you need to understand that if you’re filling the big tub without electric tankless water heater depending on how fast your tub filler works you may have to throttle it back a little bit where you can keep up it will fill the tub but if you flow the water too fast for it to heat you’re going to have to slow it down a little bit which is fine your tub fills up you’re not out of hot water you still are able to take the back-to-back showers and so forth if you have a higher flow rate mean than that maybe four or five bath homes body sprays things of that nature either you’re going to need to go to a gas-fired water heater or you’re going to have to double up on the electric now somebody out there right now saying oh yeah you need to have 120 130 amps to run one of those electrics and you don’t have the room of your panel that’s actually false a 200 amp panel with the water heaters.
I’m talking about the water heater panel load is only 54 amps panel load is what matters you don’t just add up all the breakers when you hit 200 and a 200 amp panel you’re done that’s not how it works however if you have to double them up if you need more than one then you may have an electrical upgrade to consider that may change the conversation so a good electric tankless can absolutely be a viable option where you get into trouble is where the salesman will tell you anything you want to hear to buy that product and that’s kind of tough salesman pretty good at their jobs so use your best judgement but pay attention to what people are telling you you’re welcome to contact me I’ll help you if I can obviously I can’t speak for every part of the country but I can maybe give you some ideas I’ll do the best I can as long as it doesn’t overwhelm me too much and hopefully this video will help you out those more heaters cost installed is probably going to be fairly similar to the smaller gas tankless water heater installation you are going to have some electrical work to do.
Some new circuits to run big copper wires are not cheap so I’m going to say that a typical 32 kW electric tankless and a retrofit is probably going to still run you around $3,000 install now next segment I’ll tell you about how you should buy your tankless water if you decide that it’s right for you alright so now you’ve decided that a tankless water heater might just be something you want to consider so you call and get a few prices guys do you some a favor get three prices figure out from the homework you’ve done in your area what brand or brand you’re interested in considering don’t go crazy with five different brands no one wants to talk to a customer like that I’m just being honest with you you need to get three prices on a reputable product reputable contract and make your decision based on the feedback you get check the references and that’s who you should do business with if you call someone up and say .
Hey I’m getting seven prices on this tankless water heater so you better bring a sharp pencil anybody worth having in your home is going to tell you to go pounce and they’re not even going to talk to you because at that point you don’t care anything about quality you don’t care anything about the service all you care about is the price and they’re not interested because you’re not going to choose them be careful people who act like that consumers if you’re one of those consumers you better quit it’s going to get you eventually because you’re hiring jack legs that don’t know what they’re doing based on price and it’s going to end up costing you a lot of money and I don’t care what it is it doesn’t have to be one of these could be any plumbing or heating item even electrician work you don’t want to hire just some guy on price you want to deal with someone that’s good reputation a good business insurance and will give you a fair price that’s how you’re going to get your best work same of these if you want to use a run.
I go to Renee’s website look for a platinum deal or preferably one with an authorized service provider ability they don’t have to have that it’s very good installers that are not authorized service providers because they don’t want to go fixing everybody else’s problems but those are the dealers you want the risk takagi navien state rheem cheese I’m sure I’m missing five or six others all these places have websites some better than others you want to deal with a reputable Trane dealer you don’t have to trust me I have nothing to sell you but I’m telling you if you buy one of these water heaters from one of these coms and then try to find somebody to install it they don’t want to deal with you you haven’t let them make any money so they could care less about your job and if something’s wrong with that appliance guess who it is now it’s all on you home centers same thing home centers typically have either remanufactured products or knockoff products sometimes made by the manufacturers themselves but there’s still knockoffs you’re not going to get the locals work.
That you would get of the full brand name product and of course again no one wants to talk to you no one’s going to want install it if you’re going to buy one of these products like that you better be able to install it yourself and do it correctly if you install it wrong chances are the warranty is void not in all cases but most cases if you just thought wrong that’s not a warranty issue number two if you install it wrong and it causes damage to your home and you’re not a licensed contractor your homeowners may not cover it so you need to think about that to the safety of your family is worth more than that if you’re interested in tankless water heater hopefully this video has helped you decide whether or not it’s right for you and again these are high-end appliances they’re not for everybody but if you think it tackles water heaters right for you I hope you will again do the licensed and insured installer so with that please hit like little thumbs up button down there subscribe to my channel check out my other tankless 101 videos and feel free to comment or ask me any questions I’ll do the best I can thanks for stopping.
