Mixergy Reviews 175

The Mixergy cylinder came pre-installed in our new-build home, so this was not a product we chose.

Despite being marketed as energy efficient, our gas bill tripled within the first month. The system consumes an unreasonable amount of energy and performs nothing like what is advertised. This is completely unacceptable for a modern, supposedly efficient setup.

Customer service has been consistently unhelpful. They do not answer the questions you ask and instead respond with generic, evasive replies that do nothing to resolve the issue.

Technical support has been even worse. Their responses give the clear impression they do not want to help, and on at least one occasion remote changes were made to the system without our consent or proper explanation. This is extremely concerning and has destroyed any trust we had in the product or company.

Overall, a very poor experience. High running costs, misleading efficiency claims, and unacceptable support. Would not recommend under any circumstances.

I purchased a direct heating cylinder which I heat using off-peak electricity at night. The cylinder works well and I like the functionality of the app. However, I'm not impressed with the company's customer support service. Most cylinders are now installed as unvented pressurised systems, but we needed to install ours vented with a cold water tank in the attic. There were no specific installation instructions for this installation method and we had a question about whether a tun dish was required. My plumber phoned the installation help line and was promised a call-back which never came. Initially the tank would not operate and it took a little while to understand that a system reset was needed. Finally, for the first 24 hours, the data in the app suggested that the tank was turning on and off at a high frequency which seemed very bizarre. A screen grab of the recorded dats was sent to Mixergy support and an automated reply said that the support team would be in contact soon. It's now a month on and I've heard nothing. However, the strange data has not reoccurred and the tank is working fine. So a mixed review for Mixergy!

My ancient hot water tank developed a leak that could not be repaired. Our household hot water usage is unpredictable and having a full tank of hot water 24*7 was costing a lot of money. Our gas water heater was also basic, with no intelligence. Looking around, Mixergy seemed to the answer.

In practice, it is even better than I had realised. On many days, we heat only 15% of our tank because that's how much we need. When my son returned home for a while, we simply increased to 25%. When we have a houseful, we will heat to 80%. It's all so efficient and easy to control. It works as promised. Everyhome would benefit from Mixergy.

Great guy definitely knew his stuff … we had issues with solar not working correctly .. it is now

Hi , I am a developer who has 14 of the mixergy tanks and now we are having problems with 1 of the tanks and they do not respond to calls or emails and we have data from other tanks to show there is a problem but nobody seems to care , very disappointed and now looking at legal action to try to resolve the situation.

So grateful to Abbas who attended our home at 10pm on a friday night to fix our water tank. After weeks and months of different electricians unable to fix the problem, Abbas was a hero to get us hot water, a simple fault that he had the knowledge to find where 4 others failed to spot.Top marks. Would recommend Abbas.

Amazing tech Daniel from Mixergy came out and fixed my boiler same day after previously waiting months for council who had no idea how to fix it. Amazing job thankyou

Great technical support and good-will fix when four year old tank developed a problem.
The tank itself does all that's claimed of it very well. Highly recommended.

Brilliant. I love the way after a couple of weeks Mixenergy knows how much water you use each day and fills the hit water up accordingly. We have never ran out of hot water, yet our hot water bill is kept to a minimum. I am really pleased we put this system in. Very clever

Since I moved to my property didn’t had a hot water, they've sent 2 previous engineers couldn't fixed the issue but when ABBAS KHAN he sorted out the problem in 15 minutes also showed me a few tricks with the tank to make sure I always have hot water and he sorted water pressure up thank

In 2021 I completed construction of two houses to the passivhaus standard. I installed 250l Mixergy tanks in both houses that are heated using the internal immersion heater. I benefit from off-peak electricity at 7p/kW from 23.30 - 05.30 through Octopus Intelligent Go and each tank draws just under 3kW for about three hours costing less than 70p. The tank is easy to programme through the app to set the electricity tariff and I can always see how much hot water is in the tank both on the app and on the visual display attached to the tank. When I go on holiday I switch off the tank from the app and have observed that it takes several days to cool highlighting how well it is insulated. Mixergy were very responsive throughout the design/orderning process and when one of the third-party supplied pressure vessels was noisy this was replaced without argument.

It just works at a level of integration no other hit water tank can

We installed a Mixergy tank as part of a major overhaul of the heating, new boiler and installing PV’s.
At first I was struggling but that was because an internet glitch, but since then super happy with it.
Knowing our kids will soon leave, it made sense to have a tank right for the house size but being able to heat just 50% or less once they are no longer here is so much more efficient.
Not cheap but you get what you pay for and we should be building for the long term.

I love the fact there is always hot water on tap and it takes minutes to heat up. It is great for the environment as you only heat up what you need. Have had the system for 3 years now

The system delivers all the heating and hot water we need. Coupled with the solar panels keeps the cost down to a minimum. As it's an all electric system we had the gas meter removed so saving on the standing charges.

The tank itself when working is great. However the customer service when reporting the tank not heating has been abysmal, and that’s being polite. Tank been out of action since Saturday 20th of February and unable to contact Mixergy over the weekend. Spoke to customer services three times during the week and am now going into the second weekend still with no hot water. There has been absolutely no desire or attempt to call me back to offer a resolution or support. Quite shocking really. Have faith in the product but no faith whatsoever in the customer service. Really poor.

Absolutely amazing service from Rob in the Technical Team. He really put himself out and went above and beyond to resolve an installation issue for me. He’s a great asset to the team. Thanks again.

Been appalling from the minute I moved in to my new home. Tried to speak to the builders about the hot water not heating up and when it does I only get 20%.

*** UPDATE***

I spoke to one of the engineers today and they came out same day within a matter of hours and sorted the issue. It took him less than 10 minutes. Abbas also showed me a few tricks with the tank to make sure I always have hot water too in case of an emergency.

Im giving two stars as when the tank works its great. Customer service alone would be one. Our tank has failed. Only source of hot water two young children in the house. Reported fault Thursday, Friday no further to help and closed over the weekend. Very dissapointed customer with a compeltely non functioning 1 month old expensive tank. They are apparently too understaffed to help!

Whilst it was a little disappointing that our iHP X cylinder broke down after just over a year's use, requiring a new control board, the repair experience was excellent. From phone support given on Boxing Day to Danny attending and fixing the boiler a couple of weeks later (we had some hot water all along via the immersion element), it was a very good service experience
