We’ve also included some of the pros and cons for each to help you make an informed decision about which is the best for your own home. As always, take the time to think about what exactly you need from a water heater and shortlist them accordingly.
1. FVSTR Electric WATER HEATER LCD FVSTR 2.5-Gallon 8L 1.5KW US Plug 120V Electric water heate smart hot water heater Boiler wash only Eliminate Time for Hot Water – Shelf, Wall or Floor Mounted
The first smart water heater we’re discussing today is this 1.5kW smart hot water heater. You may think this is a tankless water heater but it actually has a small 2.5-gallon capacity tank for hot water straight to where you need it, covering up to 2 sinks. Thanks to its size, it can be mounted on a shelf, wall or floor and the installation is pretty easy to do.
With this smart water heater you can choose from four different power levels depending on the performance you require. Furthermore, you can easily adjust the temperature thanks to the water flow regulator included within the packaging. For those wanting an additional water heater at a specific sink or to help boost an existing hot water heater system, this premium solution is a great choice.
2. Aquanta Digital Water Heater Timer – Wifi Smart Water Heater Controller/Control – Smart Hot Water Heater Alternative – Programmable, Works with Electric Hot Water Heater – Leak Sensor Included
The first thing to say about this impressive smart water heater is that you can buy a version for an electric water tank or a gas tank and there are options for leak sensors too. So make sure you choose the right one for your existing set-up! This is a fantastic system for anyone wanting to control their water heater from their smartphone
You can control the thermostat and heat cycling, assess weekly and monthly usage data, and schedule heating to coincide with cheaper energy rates. As well as that, you can remotely turn it on, get maintenance alerts and get leak detection alerts. It is important to note that it isn’t compatible with certain types of water heaters such as tankless water heaters or boiler-fed systems so check the manufacturer’s guidance before buying one of these.
This tankless water heater makes it onto our list because it is a compact, efficient and effective hot water heater. Made with stainless steel, you can trust it has been made with the best materials and at 8.7 x 3.5 x 14.2 inches, it will fit in almost any location in the home.
Where smart technology comes into play on this water heater is its LCD control panel. You can easily manage the performance of these smart water heaters by making adjustments to the panel. This includes programming the exact temperature required to ensure energy use is optimised. The flow switch activation mechanism in this water heater allows it to ensure constant temperatures with as little as 0.5 GPM, once more maximising performance and minimising energy usage. This is one of the smaller tankless smart water heaters and so if a flow rate of 2.5 GPM isn’t enough for your household, we suggest looking at the bigger water heaters on our list.
4. Electric Tankless Water Heater, funwill 6.5KW 220V Smart Mini Hot Water Heater with Digital Display & Touch Control Panel, Overheating Protection, Instant Hot Water Heater for Kitchen Sink Bar, White
A more powerful tankless water heater now, with this hot water heater reaching 6.5kW. It is still a compact, efficient unit and one of the biggest pros of this model is without any preheating at all, you can have hot water within 3 seconds! The tempered glass adds a touch of style whilst helping provide greater thermal stability and electrical isolation performance.
This smart water heater has a computer chip built-in that calculates the minimum power required to heat the water you need. This is based on the temperature and flow rate and this adds up to massive energy savings and reduced energy bills. The display is easy to ready and has efficient touch controls to help set it to the perfect temperature. This water heater comes with all of the usual safety features such as leakage protection and overheating protection so you can trust it will be safe to have in the house. As always, tankless heaters often mean a premium price compared to more traditional water heaters but the benefits will outweigh that for many households.
5. Tankless Water Heater Electric 5.5kW 240V, ECOTOUCH Smart Mini Water Heater Self-Modulating Instant Hot Water Heater For Sink, Point of Use Water Heater White
This tankless water heater ticks all of the boxes you’d expect from a smart mini water heater like this. It will deliver hot water almost instantly at a temperature range of 77 to 131 degrees Fahrenheit, meaning you don’t need to wait for the water tank to heat up and you will save money on your energy bills. This smart water heater will adjust its power input based on the temperature of the water and flow rate in real-time, ensuring maximum efficiency at all times.
This smart water heater has a digital display and a simple temperature setting knob so there is no complicated process to follow each time you want to make a change to the temperature. We also love the safety side of these water heaters, with a clear indicator light to tell you of any specific issues and multiple protection devices to ensure it is as safe as possible for your family to use. At only 10.65 x 5.15 x 3.35 inches it is one of the smaller tankless water heaters and will fit in almost any room in the house, particularly useful for small apartments and homes. Do be aware that it is a mini tankless water heater so don’t expect it to cope with demanding households or for locations where the flow rate isn’t great, so do some research before buying it to know what power you will need.
6. Sinopé Smart Wi-Fi Thermostat for Electric Heating TH1124WF (Works with Amazon Alexa) 4000 W / 240 V
This smart Wi-Fi thermostat for electric heaters gets rave reviews online from customers and that is why we have added it to this list! Firstly, it will work with baseboard heaters, connectors, and other heating and is relatively easy to install thanks to its universal connectors. It will also work with a wide range of smart systems such as Alex, Google Home, Apple HomeKit, and Neviweb. This means you have the ability to control it via your smartphone anywhere in the world or via voice control with a smart assistant.
When you connect this thermostat to Neviweb you can analyse usage data to maximise efficiency and no matter the system you use, you can control the temperature settings, on/off options and generally make sure the heating is performing exactly how you want it to. It has a backlit display to make it easy to see the relevant readings but do note that some customers have reported the temperature on this thermostat running a few Fahrenheit different from the heating systems in their homes, which may frustrate some people!
7. Smart WiFi Water Heater Switch, Voice Control Smart Touch Wall Switch with Timer, Remote Control Smart Boiler Touch Switch Compatible with Google Home, Alexa and Home APP
Yet another smart Wi-Fi water heater switch that connects with a wide range of smart appliances in the home. Whether it is Google Home or Alexa, you can effortlessly control your water heating via an app on a smartphone, voice controls, or with the clever touch controls on the unit itself. Available in either black or white, they offer a truly stylish option for those not wanting some ugly thermostat in a prominent position in the home.
The unit has tempered glass over its surface and this makes it both waterproof and scratch-resistant. It will stand up to regular use and allow you to see the LED display clearly, whether during the day or at night. With this smart water heater switch, you can set timers for your water heater, allow the rest of the family to control it, and ensure your water heater is working as efficiently as possible. All of this means greater control over your energy bills and ultimately reducing the cost of your water heating. With this smart water heater switch, you get a 1-year quality warranty which seems to be standard for this type of technology.
8. EcoSmart ECO 11 Electric Tankless Water Heater, 13KW at 240 Volts with Patented Self Modulating Technology
EcoSmart truly makes fantastic smart water heaters and this electric tankless water heater is no different. If you’re searching for on-demand hot water whenever you need it, then it’s always a good bet to go for an EcoSmart water heater. This is their 13kW version but you can find a range of capacities depending on your household requirements and with dimensions of 3.75 x 8 x 11.5 inches it will fit in almost any location in the home.
This smart water heater is 99% thermal energy efficient, so you can trust it will save you money in the long run. It monitors water temperatures to ensure consistent performance as well, keeping it within 1 degree of your desired temperature at all times. It will provide between 1.3 and 3.1 gallons per minute (GPM), depending on the inlet water temperature which is great for a bathroom or small sink, but may not be great for busier households so do think about your water usage before investing in one of these premium water heaters.
A slightly different smart water heater system now, with this shutoff system joining the list. The reason for this is that we feel it tackles one of the most important and potentially damaging issues homeowners face. That is when there is a water leak and you either don’t notice or you’re away from home for a period of time. This smart hot water heater shutoff system takes care of all of that for you.
A relatively inexpensive piece of smart technology, it requires minimal installation as it attaches to existing plumbing and can be used very easily. If the system senses water around this hot water heater shutoff sensor then it instantly shuts down the supply and sends notifications to your mobile phone. It also produces a loud alarm when a leak occurs, shutting off the cold water input whilst also continuing to notify you. A fantastic idea but one concern we do have is that you can’t control the audible alarm from the mobile phone. This means that you need to physically be there to turn that off which may be frustrating if you’re away or cause alarm to neighbours if they hear it.
10. EcoSmart ECO 27 Electric Tankless Water Heater, 27 KW at 240 Volts, 112.5 Amps with Patented Self Modulating Technology,White
Another smart option from EcoSmart is their 27kW water heater, perfect for most households who don’t want the hassle of a large water tank taking up space. Throw in the fact that tankless systems only provide hot water when you need it, meaning you reduce your energy bills and it really does sound like the way forward for most people.
These water heaters are approx 90% smaller than traditional heaters and can be installed on a wall or at the point of use depending on what is better. With dimensions of 17 x 17 x 3.75 inches, it will fit almost anywhere in the home. EcoSmart has created a hot water heater that is 99% thermal energy-efficient and this means you will save up to 50% in water heating costs. This model will deliver hot water at a rate of between 2.7 GPM and 6.5 GPM depending on the inlet water temperature, so you should think about the water temperature before investing. If you live in a particularly cold place, you may find the performance for the price isn’t as good as you need.
