 I am Nate Adams often known as Nate the house whisper and I wanted to do a quick video on comparing a heat pump water heater and an electric resistance water heater because I happen to have two houses with energy monitors on them and one has one and the other has another so it's pretty interesting to see the interplay so here are our two houses so there's the river house this is in Cleveland Ohio it's 1400 square feet it's a ranch it's a weird one because it's actually on stilts it is 15 feet from the Cuyahoga River hence the name and mountain escape is what we call this house it is in Fayetteville West Virginia so it's kind of funny this one has a heat pump for space heat but an electric resistance water heater this one has resistance for space heat and a heat pump water heater so neither one of them is fully complete where I would like them to be but that's that's real life so I'm glad at least I finally have a heat pump here after years of talking about them I finally have one but wanted to show you so this is the Emporia view web app which I really like because it makes it easier to see more stuff on the screen at the same time so like I can click on the river house and I have eight lines clamped up there so I had barn one and two clamped because I had a Chevy Volt before I had to turn it into a van for being able to tow our camper around but I had that clamped and then you can see the other thing so you can see what the induction range is doing did the outlets in my office but note the heat pump water heater down here so it is not running at presence and then I can click on mountain escape down here and it won't quite show you everything particularly because I have 16 circuits clamped on this one but you can see what's going on so heat pumps running pretty low right now it's probably we're going to be ramping up yep see over here was it 800 watts and it's coming up so it turned on and it's it's ramping right now as we speak but you can get a pretty good idea pretty quickly what's going on so I wanted to take a look in particular at a very specific period so here is December 19th we went up to Ohio so this is our Virginia house West Virginia house when we went up to Ohio and so you can see there's just standby losses here which means the water here was on and this is how much energy it took just to heat the water as it was falling in temperature now to be fair I turned the temperature down on the house so it was only 60 degrees here so it did have more losses than the normal 73 degrees that point I have but take a look at so see the usage up here five kilowatt hours a day when we come back but let me slide this over so look we're using almost one and a half kilowatt hours a day well there's one and a half so it's pretty consistently around one and a half kilowatt hours a day of standby losses so it's not actually heating water just keeping it warm no waters being used run that back over here get that to where it says 1219 here so we're using one and a half kilowatt hours a day just for standby losses on a resistance tank so this is the resistance one now here's the heat pump so let's look at the same period so we were up in Ohio and for whatever reason you know it was every other day was showing more usage from doing laundry or something like that but when we were home so this is right at the same day this is the water heater doing its job so not only is it standby losses but it's actually you know doing showers and laundry and washing dishes you know and just whatever other uses we had for hot water look it's not that much more and so some guests like the so we Airbnb this house so here are some guests working at hard and it's using three and a half kilowatt hours a day or go a little bit further so here's one of the highest peaks you're gonna see at about four kilowatt hours a day so two things to note here when the the heat pump water heater and it's my family is my wife and I and my daughter when you're talking a family of three the standby losses are basically the same as the usage for the heat pump water heater actually doing the work so gives you an idea of the efficiency swing between them so not that it's all about efficiency but like this is one of the rare cases where you can reduce energy use seventy or eight percent for the same basic service now there there is scavenging from heat inside the house so there's there's other pieces of the puzzle but the basic usage of the machine itself is way way less so let's go back this is the river house so it's the heat pump water heater let's go back to mount escape and just look at our usage with the three of us so you saw that we were using like two kilowatt hours a day on the high side look so we've got plenty of days that are way more than that so I mean like eight you know there's just lots of days that are more than two kilowatt hours because a heat pump water heater is three to four hundred percent efficient that's legit we actually are seeing those kinds of numbers now let's look at it from a monthly perspective so here is the river house this is the heat pump water heater so you can see it's using somewhere in the ballpark of 50 kilowatt hours a month you know somewhere in that range not dead on every month it's gonna vary and so the house isn't always full either so there's not always an Airbnb guest there although I do have to say the occupancy has been pretty good I guess it's been 70 80% but then here is our place so we're using a hundred 60 kilowatt hours a month versus 50 so there you are you can see that we're easily using two-thirds less electricity for a heat pump water heater versus an electric resistance so that might be interesting to see so and you saw day by day we saw what the standby losses are but the wildest thing to me was that the the standby losses scroll back to the 19th here the standby losses on an electric resistance water heater are not that different from the actual usage of the heat pump water heater heating our water to be used so when we're living there so that that was pretty wild that that might be interesting to see and if you like this video I do lots of other things like this so you know the drill so subscribe click the bell all that good stuff have a great day I'll see you in the next one bye bye
