Last update: January 18, 2023

Are combi boilers going to be phased out?

There is no definitive answer to this question as of yet. Combi boilers are still a popular choice for many homeowners due to their space-saving design and efficiency. However, with the introduction of more energy-efficient boilers on the market, it is possible that combi boilers may eventually be phased out.

Are water boilers cheaper to run than kettles?

Water boilers are cheaper to run than kettles. They use less energy and water, and they boil water faster.

Do combi boilers need hot water tanks?

No, combi boilers do not need hot water tanks. Combi boilers are able to heat water on demand, meaning that they do not require a tank of hot water to be stored. This makes combi boilers a more efficient and space-saving option than traditional boiler systems.

Do hot water dispensers use a lot of electricity?

Hot water dispensers are an extremely convenient kitchen appliance that can save you a lot of time when preparing meals. However, some people worry that hot water dispensers use a lot of electricity and can be a drain on their home’s energy resources. The truth is that hot water dispensers are actually quite efficient, and use much less electricity than other kitchen appliances such as coffee makers and microwaves. In fact, hot water dispensers only use about as much electricity as a standard light bulb. So if you’re looking for a convenient way to save time


Costway Instant Electric Hot Water Boiler and Warmer, 5-Liter LCD Water Pot with 5 Stage Temperature Settings, Safety Lock to Prevent Spillage, Stainless Steel Hot Water Dispenser Review:


This works as predicted, consumes 700W when heating, and has settings that may be changed to maintain desired hot water temps. Regardless of the setting, it always heats to boiling before cooling back to the set point, where it will simply turn on and off as needed to maintain the desired temperature.The LCD display lights up green or red depending on whether the device is heating up or is ready to use at the selected temperature when it is in operation and emits a cool blue light. The main disadvantage of this unit is that it is rather tall and has a much larger capacity than the other ones I've looked at. If you intend to place it beneath any cabinets, you'll need at least 17".When filling the water reservoir, you must move it out of the way so that there is at least 2 feet of space to open the hinged lid and pour the water in.Although the base may swivel so that you can orient it in various orientations when dispensing, I never utilize that feature because I always put it facing the same way. It's convenient that there is a translucent tube that provides a quick visual of the water level.You can set a timer to delay maintaining the water temperature for a predetermined number of hours in order to save energy by not keeping the water at a high temperature while no one is home. Although it's not completely insulated when the water is at its maximum temperature (195 degrees Fahrenheit), the exterior covering is warm.It has a spout switch that allows you to dispense the hot water with one hand by pressing the button on top with your other hand while holding the cup up near the spout or by just placing the rim of the cup up against the ridge at the spout. The spout is so high up that it will splatter if you just leave the cup on the counter. However, if you need to fill certain tall containers, the height is useful. If the unit locks out because it is still in the heating mode or if the power goes out, you can manually pump out the water by pressing a button on the top of the lid. Because it takes so long, you generally won't do it frequently.Of the ones I looked at, this one offered the best value and had all the features I required.The only thing I would have preferred is if there had been a way to add the water without needing such a large amount of top clearance.However, considering that all the others had far lesser volumes, that is the cost associated with the enormous capacity reservoir.The ability to heat directly to the target temperature without having to overshoot to the boiling point and then return to the set point might be a valuable feature.



Zojirushi CD-LFC30 Panorama Window Micom Water Boiler and Warmer, 101 oz/3.0 L, White Review:


bought as a result of the positive reviews. Works and looks just fine.That there isn't an on/off switch surprised me. This heating system operates continuously. I'm hoping it has an overheat and no water sense safety off. It annoys me to leave an electric heater on while I'm away for extended periods of time. I'm set up so that I have to get on all fours to reach the plug so I can unplug it from the wall. It would have been simple to have a programmable on-off, or I could have had one just for when I'm gone at work during the day, like the $20 thermostat I have on my wall. But maybe the device doesn't use as much power when it's on all the time, and maybe safety (controlling bacterial growth) is better at constant high temperature.Minor point: since it's always on, I believe it should be built for nighttime use. But for use at night, I have to turn on an overhead light. For me, a small LED lamp to illuminate the area under the spout would be helpful.Also, the form factor could have been a little bit taller so that I could fill the thermos I use.I would have preferred a temperature of around 145 because I have to dilute my instant coffee at a temperature of 160 with a little cold water. The temperatures listed at 208, 195, 175 and 160 correspond to those used for brewing tea, as you should be aware of.Since I'm not using it in the kitchen, which has counter top 110 plugs, the 33-inch cord could have been a little bit longer.*** Updated in January 2019: Working well even now. In order to avoid cleaning issues, I use distilled water. I'm unplugging the device from the back so I can travel on the weekends.Update for one year review. Still a reliable piece. I once used vinegar to clean. There are no fresh findings.This is NOT a paid, unpaid, or sponsored product review.



Zojirushi CD-WCC30 Micom Water Boiler & Warmer, Silver Review:


I adore this item! Although I was on the fence, I'm glad I bought it. Being able to simply turn to the side of my desk, dispense hot water, and then wait for the tea to steep is quite convenient.Several usage notesI nearly always use the default temperature option since I don't want to wait for the water to cool down to utilize the lower temps and it works perfectly for most teas. I seldom use the boil feature because I only ever add filtered (Brita) water; nevertheless, I occasionally let it boil to destroy any bacteria.I usually drain the residual water after a few months and gently wash the interior with dish soap and a cloth to get rid of the thin coating that forms.usage of electricityDepending on how much water is in the tank, this device uses 700 watts of power to heat for roughly 15 to 20 minutes. To keep the water warm, it continuously consumes 30 watts of power. If you're concerned about energy consumption like I am, heating the water uses roughly as much energy as maintaining the temperature for 10 hours. So keep the hot water on if you won't need it again for at least 10 hours.Final point: I laughed the first time I heard the mini-symphony-like musical note it plays when it's ready with hot water after heating.



Tiger PDU-A30U-K Electric Water Boiler and Warmer, Stainless Black, 3.0-Liter Review:


This water heater is excellent. My family uses it for an entire day, so the 4L capacity is ideal. After using the Zojirushi 3L version of this water boiler for approximately a week, we decided to upgrade to a larger one. Because the 4L of the Zojirushi would have taken too long to arrive at the time, we were forced to use the Tiger (Like a month, if I remember correctly). I'm satisfied with the purchase overall, so let's get started.I like that it takes a respectable amount of time to heat up and that there is a timer to let you know when it will be ready. It lacks the Zojirushi's adorable soundtrack, but that's okay. Because the 208F setting is reduced to 203F, which is better for coffee, I like the water-saving option. Aside from that, all the "standard" and "common" features—such as the swivel bottom, the magnetic plug, the declorination process, ease of filling, visibility of remaining fluid, etc.—are excellent.Things I would change: The'shiny' and huge dispense button is lovely and simpler to use, but I don't like that the steam can be uncomfortable on your hand or fingers if you are dispensing a lot of water. Because it is located higher on the panel, the Zojirushi did not experience this issue. Furthermore, this one lacks a timer feature. So with the Zojirushi, I could set it to 8 hours when we went to bed, and by the time we woke up, it would actually "save energy" and self-boil to temperature. Even though these don't matter all that much to us, they deserve to be mentioned.Other factors to take into account if you are researching the Tiger:It appears that the Tiger travels horizontally whereas the Zojirushi goes vertically to hold more. Therefore, if you are limited in height, this is certainly a better option. For my part, I had to construct a little platform so that I could place my french press beneath the Tiger. Finally, the Tiger lacks the "cafe drip" setting, which essentially just slows down dispensing.



Zojirushi CD-JWC30FZ Micom Water Boiler & Warmer, 3.0 L, Natural Bouquet Review:


trustworthy product. I purchased this to replace my previous one and another one for my folks. We frequently drink tea, which makes things much simpler and quicker. It never has a terrible taste in water. When you notice brownish residue in the kettle's bottom, make sure to clean it with the citric acid cleanser.



Buydeem S7133 Hot Water Boiler and Warmer, Fresh, Instant, Adjustable Temperatures, Best for Infant Formula, 2.6L, Pink Review:


To replace my Zojirushi always-on water boiler, I was seeking for a new water boiler. I know that buydeem produces high-quality goods because I have already purchased from them. So I decided to purchase this.Let's discuss several water boiler options, their advantages, and disadvantages:1. Boilers that are designed to be running constantly and that provide hot water practically instantly do so by reheating the water when the temperature dips. This provides you with hot water instantaneously, but because water must be reheated repeatedly, it may leave a scent in the water and uses a lot of electricity.2. Let's talk about the at-runtime heating solution (this water boiler), which warms or boils water to the desired temperature at the time it is dispensed, ensuring that water is always freshly heated or boiled and preventing the loss of energy. You will have to wait a little period of time for the water to heat up and distribute.Let's revisit the buydeem water boiler and examine the advantages and disadvantages.Pros:1. This style is ideal for small apartments and dorm rooms because it is modern and compact.2. You always have access to hot, freshly boiled water.3. Two pre-set water volume options are available (small: 3-4 oz and big: 7-8 oz).4. A range of drink temperature possibilities, from room temperature to boiling point.5. Water dispensing is quite efficient, which results in very little splashing.6. It offers a practical built-in cleaning/descaling option.Cons: 1. There will be a delay in getting heated water because it is a boil-at-runtime water boiler. It could get bothersome if you need a lot of hot water.2. I would advise using pre-filtered water because there is no filter option and it is difficult to forecast how much scale will accumulate over time. This way, you won't have to worry about it.Conclusion: This is a great option for preparing instant noodles, baby formula, and those quick tea or coffee brews. If you're searching for a hot water boiler, you should definitely narrow your list. Thanks



Secura Stainless Steel Water Boiler and Warmer w/Night light | Electric Kettle Water Heater, Tea Pot w/Auto Shut-Off Protection, 4-Quart (2-Year Warranty) Review:


In this home, tea is consumed frequently. I refer to 8 or more glasses per person per day.After many years of dependable service, our old Zojirushi water boiler eventually failed. I considered purchasing a second Zojirushi, but they are expensive (about $200) and the plastic water chamber always gave me the creeps. So I decided to give it a try when I spotted it on sale.First of all, this item gets hot, as several reviews noted. It is so hot that resting your hand against the sides or the back for more than a few seconds is impossible. However, if your children are mature enough to obtain hot water on their own, they are also wise enough to avoid touching this device while doing so. similar to how they shouldn't grip the toaster or kettle's side.The temperature settings are 176° and 208°. In our home, 176° is too low to properly brew tea, thus we maintain it at 208°. Our last one had 195° as well, which was ideal. Send a message to the company to maybe keep in mind for the improved model in the future.Though very feeble, the nightlight is a wonderful idea. It has to be a little stronger to be useful for situations like these, where you don't want to risk awakening the baby by turning on the overhead lights but yet need to fill hot water to a specific level for the baby's formula.Because it is made of plastic nubs on a circular plastic disc intended to allow the dispenser to revolve, the base can be a little slick when placed on a marble or granite countertop. Allowing a pot of nearly boiling water to rotate, in my opinion, is foolish and maybe hazardous. To keep mine in place, I placed a sizable round cork placemat below.Finally, the hole is large enough to make cleaning and water addition simple. This object won't topple over because the base is wide enough.The item appears to be holding up well so far, but I have not had it long enough to judge its durability or possibility for rusting.Overall, it performs admirably for the price.



Chefman Instant Electric Hot Pot Coffee Urn w/Auto & Manual Dispense Buttons, Safety Lock, Easy Water View Window, Auto-Shutoff & Boil Dry Protection, Stainless Steel, 3.6L/3.8 qt/20+ Cups Review:


The water in this urn can be used for anything, including making tea, coffee, instant soup, quickly bringing a pot of water to a boil for cooking, or simply having hot water on hand for cleaning when hot tap water isn't available (but be cautious, it's quite hot). My instant read thermometer indicated that a full urn takes around 30 minutes to reach its maximum temperature, which is between 185 and 190 degrees F. This temperature is more than high enough for anything requiring boiling water. Dispensing is really simple. I prefer the dispense button, but if you only have one hand, you can use a little switch inside a cup or pot, and if there's no power, you can use the manual pump.Although it says to change the water every day, I haven't experienced any taste or temperature issues after keeping it around for a few days. The front of the boat has a gauge that displays the water level. They added some diagonal lines, which I like since it makes it simple to see the level because the water bends the light and makes them appear horizontal. Since it doesn't fit under my faucet, adding water is a little more difficult, but it can still be done with the help of a pitcher or the spray attachment. Its included detachable cord is the same kind used by most desktop computers, certain laptop bricks, and some TVs, so if you take it with you and decide you need to create additional hot water while you're on the go (it keeps water toast warm for a while unplugged), finding a spare cord should be doable.There aren't many real drawbacks. It is meant to switch off if the battery runs dry, but there is no power button. If I were to leave town, I would probably unplug it. The exterior housing does warm up, getting almost hot at the top, but not hot enough to burn.Overall, if you want to have a lot of hot water available all day long, it's perfect.



Chefman Instant Electric Hot Water Pot Coffee Urn w/ Auto & Manual Dispense Buttons, Safety Lock, Water View Window, Auto-Shutoff/Boil Dry Protection, Insulated Stainless Steel, 5.3L/5.6 Qt/30+ Cups Review:


REVIEW UPDATED: My first was a disaster (see below). The business was very gracious and sent me a replacement unit gratis.This device operates flawlessly. It maintains the water's heat and, like the other two units, dispenses water via the pump or by pressing an electrical button. This option is one that I really like, which is why I initially bought it. This new unit doesn't frequently reboil. It occasionally makes a very quiet cooking noise, but otherwise it is quiet and does not frequently reboil.reviewing reviews from others The internal button thermostat that tells the unit when to stop boiling appears to be defective in some units. If yours has a flaw, it will either reboil too frequently or, worse yet, keep boiling the water out of the top back seal, damaging whatever is above it.Get this device; it's awesome when it works and reasonably priced, in my opinion.But if you buy one and it reboils every hour or so, don't keep it; return it right away to avoid experiencing what I did.My new unit is fantastic in every way!My Prior Evaluation:Does Not Function WellHere are some issues I've encountered:Problem 1: The unit repeatedly boils and reboils, much more frequently than other units of the same type.Problem 2: My cabinets have suffered steam damage due to the rear vent's improper seal.Problem 3: The water will occasionally simply boil out because the top-back seal leaks steam.



Electric Auto Hot Water Dispenser - Instant Fast Heating Coil Water Boiler More Simple Then Water Kettles Pots Clear Water Tank Measuring Fill Water Up To 2.17 Liter NutriChef PKHTWTR46 Review:


• PROS: I've been looking for a hot water dispenser that will swiftly heat an INDIVIDUAL SERVING of water to the ideal tea-brewing temperature of 212 degrees, and this one perfectly fills the bill. It's great that this model allows you to choose the exact number of ounces to dispense (4, 8, 12, or 16), as it just takes a few seconds to boil the water. Additionally, a variety of temperatures up to boiling (212 degrees) are available, which is just what I needed. Other dispensers require you to boil an entire pot of water, then reheat the previously cooked water, which wastes energy and can change the flavor of the water. It has a good capacity for water, holding about 2.17 liters (about 73 ounces or nine 8-ounce glasses in the United States), and it alerts you when it starts to run low. It comes with a replacement water filter and is simple to add more water with a measuring cup. It doesn't take up a lot of room on my tiny countertop and has a fairly compact footprint.• CONS: When replenishing, the water takes a little time to pass through the filter, although this is not a major issue. Just to keep it full, I try to remember to occasionally add a little water. It does come out piping hot, but I'll admit that because I enjoy my tea very hot, I occasionally reheat it in the microwave for 10 seconds to maintain the piping hot temperature.• THE SUMMARY: I ADORE IT! Since taking it many times per day for about a month, there have been no issues. I have no reservations in recommending the NutriChef Instant Hot Water Dispenser to my fellow tea aficionados, barring any unforeseen complications.ADVICE: In case it stops heating, try this. TIP: Try disconnecting it for a moment to "reset" it. Reconnect the plug when you return. It worked perfectly when I first got it, but then it stopped heating. I called the manufacturer and was about to send it back, but I'm glad I held off because I now use it frequently and I adore it. I had also attempted the little pinhole reset button on the rear, but to no avail. My handyman, however, advised me to unplug it in order to RESET it, and he was correct. Since then, everything is fine.(Also, confirm that there is adequate water in it. Water won't heat if the level drops too low. However, you already knew that.) Unplug, wait a little, then plug back in if you're unsure. Works perfectly.

What are the problems with combi boilers?

There are a few potential problems that can occur with combi boilers. Firstly, if the boiler is not serviced regularly then it can start to build up a deposit of limescale. This can then lead to the boiler becoming less efficient and eventually breaking down. Secondly, if the boiler is not used for a long period of time then the seals can start to perish and leak, meaning that hot water and/or central heating could be lost. Finally, if the boiler is not installed correctly then there is a risk of carbon monoxide poisoning.
