My Sunamp heat batteries have failed ! 

Thanks for watching and your comments 🙂

This 'was' a new technology, my new sunamps have been fine 🙂

Thanks, will do! Thanks for your comments and watching 😊

Thanks andrew for your comments !

That’s a long time to go without hot water , a plumber would only take a day or two sunamp have to match it otherwise less people will want to try it and stick to cylinders or combi with there setups

i wonder what the weight is of a full 240 ltr immersion cylinder is ?

@@JonathanPorterfield Well the copper cylinders are pretty light but 240L = 240kg

Hi , Yes the 'smile' project ended back in 2021 , and the sunamps where 'free' for me to keep etc , or they would restore my old immersion cylinder , but I stuck with the Sunamp system. The new 12kWh sunamp is performing great too , Mrs P likes deep hot baths , and to date , ive not 'ran out of hot water' after a large bath , showers , hot sink water etc , in a day with little solar to 'top up' the system in a 12 hour period.

Hi Doug , this is a 12kWh sunamp , so this is the amount of energy it will take from 'empty' when all the PCM needs to be 'charged' ready. Day to day use is around 2-3 kWh of energy to get back to 100% after 2 showers , and washing up etc . We have 3 adults in this house for reference.

@@JonathanPorterfield cheers Jonathan , I thought as much but just wanted to make sure. Thank you

100 % Yes ! See this video too ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mAXl2Y_BTQQ.html

Sunamp covered everything ! Replacement and installation costs , i paid nothing 👍

Hi and thanks for your comments 😊 if you watch the top video shown at the end of this sunamp video , you can see my whole set up !

Hi Derek , yes the 'new' sunamp has been faultless, and massive improvement over the old 3 separate units, 100% recomend this new one.

Our shower is run direct from the sunamp feed , pressure is very strong 💪

My Shower is brilliant as well, hot water at mains pressure. My daughter prioritises her showering at my house over the electric shower at her Mother's house.

Just looked at it again. It actually says max pressure 10 bar which makes way more sense! My mistake. The hard water issue is still there though.

The manual says ' where mains water hardness exceeds 150ppm Total Hardness , you must install a scale reducing device inbthe cold water supply to the heat battries'

Yes ! It fills a bath just as fast as an immersion tank ! Shower is just the same as before too.

Around 1 hour to boost and i have enough for a good hot shower

The booklet states that this 12kWh unit can supply 370 ltrs of hot water from a 'full charge' , That's a lot of hot showers !

Thanks - I’m keen on this technology but haven’t found much info on how it works in practice. Are there several phase change components which fire off in sequence or is there just one massive store which is contained through insulation? There’s a big difference between washing your hands and running a bath and I’m keen to know how it manages that demand efficiently! Thanks for responding to my earlier question 😎🍻

Hi Colin , perfect , no issues at all , and the one complete unit is better than the 3 we formerly had , plus the green lights 'state of charge' is great to see now.

Thanks for getting back to me. We’re seriously considering SunAmp for our new build in The Scottish Borders and your experience had me slightly worried. It’s good to hear things are working well now.

Non needed !

All of the above ! Plus an effective way of storing energy from excess solar , zero legionar possibilities too.

No , its a concrete floor , so no damage done.

If using a heat pump make sure to have a separate charge times to CH demands as you'll pull all the heat out of the sunamp and then have cold water, you will also need a high temp heat pump has to reach over 65° to activate the phase change.

I have a Uniq 9 SunAmp, equivalent to 210L of hot water. I get 4 showers out of my fully charged SunAmp and I've never run out of hot water when having the occasional bath.

This 12kWh sunamp is good for 370 ltrs of hot water from a full 'charge' Average bath is 100 ltrs , so over 3 baths of hot water 😊

@@JonathanPorterfield Wow, that's good actually!

Sunamp where fast to change mine , and the newer units are better

@@JonathanPorterfield Hopefully 🤞🏼

We dont have any radiators, we have a Air Source Heat Pump for our heating. See my other video on this.

Waiting on sunamp to report back , the units have been returned to factory. 👍

@@JonathanPorterfield thanks. Will be interesting to know if it’s something they’ve re-engineered in the later models

@@JonathanPorterfield It's really important that Sunamp do fix the problems they are having with reliaiblity. Yes, it's new technology, but neither thye nor their customers can afford for there to be too many failures. Their reputation hangs in the balance. I hope their CEO is focused on root cause analysis of all the failures. I'd be wanting daily updates from the engineering team if I was the CEO.

It can include radiators , but hot water is better suited to these units.

Easy , just turn on the tap ! Mrs P loves a deep hot bath , we've never ran cold from hot tap ! I prefer shower and even after she's ran a bath , shower is still hot hot hot !

The tank doesn't heat up markedly, that's the advantage of using a phase change material for storage. Because the temperature doesn't rise there are fewer losses. The Sunamps are rated to be roughly equivalent in energy capacity to a conventional tank.

@@eclecticcyclist so how many kWh per day on average would it USA ?

@@bobbazley5376 It doesn't use energy, it stores it from the time when energy is cheap and abundant to output it when enegy prices are high, and it does that more efficiently than a conventional water cylinder.

@@eclecticcyclist thank you for the answer, I appreciate that it does things using the cheap time but maybe I'm missunderstanding but there must be a kWh amount of energy to do a complete phase change of the system to give you X amount of hot water for showers baths doing the dishes etc I know the sunamps come in various sizes so some can store more of that phased changed energy than others so my question is how much energy does it take in kWh (5 ? 10 ? 2 ?) its not the cost just the amount to go from a completely empty Sunamp to a full Sunamp ? I've looked at so many different solutions and I really liked the sun amp but from my understanding the sunamp equivalent of a 240ltr tank used about 5kWh of power to phase change it to usuable hot water. Other systems that Ive looked at are the Cylinders with an ASHP built into the top of them that is a simple direct replacement for the existing tank but uses efficient ASHP to fil the tank at only about 1.7kWh for a full hot water tank (can be boosted with the inbuilt element)

​@@bobbazley5376 Stick to LiFePO4 batteries. Much cheaper per kWh storage, more versatile, less space required and you don't need any plumbing done.

Waiting to hear from sunamp

@@JonathanPorterfield fair enough

The faulty units are on their way back to sunamp for investigation.

Odd as the eddie and the app say otherwise 🤔

i dont know , if you have the my enegi Eddi , id say 'yes' as its a great solar dirverter.

Thanks for the clarification !

@@59seank What's your point?

Yes , the installer returned and fitted correctly with thermal tape 👏 👌

@@JonathanPorterfield thank you for the reply sorry but as an MCS assessor it's one of my biggest grippes, glad you got it sorted

I know. It was absolutely exhausting having to go back a few seconds and pause the video. Not sure if I’ll have the energy left now to even have a cup of tea. Think I’ll take a nap.

I doubt the creator felt like being as much a jerk as you, so maybe they'll be open to constructive criticism.

I thought it was a good suggestion, and CastleKinght agreed with you?

Hi , but more efficient, and less energy looses over a conventional immersion cylinder tank.

@@JonathanPorterfield I dunno seems to have lost quite a lot... Of vinegar! Conventional tanks work for 20 to 30 years yours barely made a year or two so that doesn't bode well.

​@@MrButuzConventionnal tanks last more often 10 years than 30 years because of corrosion and lime build-up. Those 2 problems are solved with the Sunamp solution.
