Hi, I have a commercial project to replace two small 145l gas fired calorifiers. This looks like it would be a viable alternative without replacing flues, lowering our carbon footprint and hopefully supporting lowering energy. Have you two in tandem with single dhw secondary return?

Why can't the hot pipe from the plate heat exchanger be at the top of the cylinder with the cold return to the plate heat exchanger? Then the cylinder will heat top down. There will still be a large heat differential between the flow (hot) to the cylinder and the return (cold). Then useful hot water is available at the taps quicker.

Could you explain this concept of a “heat pump” on top of the cylinder? I am not familiar with this setup. To be fair, in a home equipped with smart meters you can use your in-house energy monitor to determine how much electricity and gas a regular boiler is using when heating. So I presume this would be the same with this Mixergy system.

The monthly service charge puts me off buying one

What is the correct size and model for 5 bed flat in london ? Using electricity

had to watch the video muted, phew that music. lol. I would like to find out some more information regarding your tanks specifically the heating times to heat a full tank (300L) from cold to 45'C. With the aim of having a spontaneous bath of even hot tub (1000 L). Would it be be necessary to slowly fill a bath / hot tub to keep some heat in the tank . Or fully empty the tank then, fill cold and reheat. How much energy would be used in heating a full tank to 45'C from cold say 5'C?

Is there a mixergy stockist in Northern Ireland?

Ready to buy, are they released yet?

That's really clear and useful thanks! Please can you do another one that explains how Solar PV divert to a Mixergy Tank works?

Well done guys. I was wondering myself when someone would use AI to heat water.

Brilliant. 👏🏻

Great information well done 👍🏼

Excellent vid

Very good video - I like this new series of videos. They are clear and informative. Thanks!

Inspiring and forward looking. If only there was more going on like this wonderful example of what can be done - today!

Great to see this video - really clear and useful. The question I would have is whether your advice on using PV power with the tank is valid when you have a heat pump, especially in the summer. We heat our 210 litre tank from about 20% to 75% daily, with the top of the tank reaching 44 degrees (and the heat pump running to about 50 degrees maximum flow temperature). The daily heating in the summer typically uses about 0.7 kWh of electricity - very efficient. I am certain that the immersion heater in the Mixergy would consume significantly more energy for the same water heating. We do get 11p / kWh from Octopus from our export, so the 'cost' to us of heating the tank is about 8p. If the Mixergy used 2 kWh of energy to heat the tank to the same level (my guess) it would cost us 2 * 11 = 22p in lost export. When we change tariff at the end of the year, the export rate will be rising to 19p / kWh, and so the cost would be more. We will be buying another Mixergy for our other property, and this will also have solar panels and a heat pump. I will be getting the embedded PV diverter, but I am not sure that I will ever use it. Any thoughts? (P.S. We do have a Tesla Powerwall at both properties).

We have had a Mixergy tank for two years now, connected to our heat pump. We heat to 75% once per day at around 1 pm when I think the heat pump will be most efficient. The 120 litre tank is enough for us to do all we need in terms of washing up and a daily bath. Our electricity use for the heat pump varies between 0.7 kWh in summer to 1.8 kWh in winter - amazingly efficient. We love the way it can be easily and quickly heated when our circumstances are unusual - such as when we have grandchildren to stay. It is a brilliant piece of technology and so simple to use.

I'm considering replacing the existing combi boiler with an ASHP + Mixergy tank. would I need also a buffer tank for the ASHP to operate efficiently or does the Mixergy tank also act as a buffer tank ? thanks

I have a large 4 bedroom house, in summer the loft gets very warm. If I put the intake vent at the top of my loftspace and the cold outlet at the bottom, would this save me even more by using this free heat energy? Would this also work in winter?

This will be the final piece in my removing gas from my home. Hoping to hear when it’s available to install and finding a competent installer in south Devon.

Do you know what the COP is in winter if drawing air from the outside?

Would be good to know: 1) Sound emissions when running 2) If existing gas boiler can supply back up if needed? 3) Any ducting requirements for airing cupboards in homes?

When will a spec sheet be out. Particularly interested in running noise levels, capacities and recharge times versus your “traditional” cylinders

Revolutionary!

A fantastic piece of equipment

I have a traditional underfloor heating system? We have underfloor heating on the ground and first floor and radiators on the second floor can a Mixergy Hot Water Tank work with it?

Great video. Do you provide any training, schematics so to learn. Thanks Alan.

As new plumber I would like to recommend it to my new customers 🙂👍🏼

Good to see an installer taking the time and effort to understand how this all works. We just need a lot more of them!

How much is it?

Really good overview of how it works!

Great video - thanks. Interesting product and co-existance with a heat pump. Great tech.
