    We have had an I-Boost for just over 8 years and its diverted 10.07 MWh in that time. Since the last week of Feb this year I think we have had to use the Gas boiler around 10 times to heat our 170 ltr tank because the Sun has not produced enough hot water by diverting. If we have had no sun then its an hour or we might top it up anywhere between 15 and 30 minutes. The 3 of us have become quite proficient in figuring out what we need. 

    For us it was probably the best £150 added to our installation cost. 

    We also rota when the washing machine and dishwasher goes on. Even look for Sunny days to do the ironing, which sometimes during the leaner months can be a 2 week wait! : :) 





    I was fleeced £500 for an equivalent 5 years ago so £150 seems not too bad.  Without a battery that'd almost be a no brainer assuming no equivalent export payments.  With a battery I still doubt the financial benefit. 

    I do enjoy scalding my hands at this time of year too :-)

    I don't agree it was a mistake to install the iboost. If the battery is satisfied it will take the edge off your water heating bills. Nothing wrong with that. Also - the best can be made out of how you use your power. Delay washes and dishwasher to be in the middle of the day but not overlapping each other. The iboost can divert any amount of spare energy to heat the water as long as the thermostat allows it. My 240litre tank needs about 9.6 kwh to heat from cold.
    Lastly if you have two immersions, on one tank, the iboost should do the top one first. That should be designated htr1.

    This is a kick in level issue. The iboost will wait for 100kw of generation but you battery will come in first. You can change the level the iboost cuts in at in the settings.
    Yes I am now delaying washing machine etc to later in the day, however the battery kicks in first and takes a few hours to fill. My immersion only has the one to heat internally from what I can see.  
    Correct my if I'm wrong as a solar only user but if you have a battery, and it's DC coupled/hybrid and not empty, apart from reducing cycles on the battery, you could just put the washing on as needed/convenient etc as the energy would just equal out over the day?

    Plus then you can get the clothes out quicker to use the legacy wind and solar renewables device.
    Not at as simple, throw in the iboost and you need to plan what is priority, which the system will determine ie consumption > battery > iboost 

    If you wish to have some hot water you will need to move washing etc to somewhere towards the middle/afternoon to first  allow sufficient kWh to be diverted to the iboost.

    Do you think its worth while adding additional panels to both roofs? I have hardly anything to export and my consumption is usually around 20kwh daily with generation typically around 21kwh on a good sunny day. Often I have to plan my day plus the water is only warm by early afternoon from the iboost.

    I wondered about commenting on that, too!

    Is there a reason why you didn't fill your roof when your system was fitted, that would've been the obvious time to add more panels?
    Also, you are a high electricity user, something like 3x the average household. Is there a good reason for this or could you make reductions?

    Not sure what you mean by Flex? I know some basic wiring but not sure what needs triming ? The earth cable ?

    I was advised by the installer the 4kwP is sufficient and to see how the system operates before making any further decisions. My roof has plenty of space for further panels so no issues there, my daily consumption is around 11 to 12 kWh but with the iboost can be upto 20kwh. I wfh mostly so not sure if there is more consumption then normal. Have been using the washing machine, oven and dish washer more often but at different times. Generally trying to be efficient with power at home.

    the  white of  the cable needs to be under the black of  the  cable   clamp do it  with the power turned off, a  4 kw  system  is  usually what the power companies allow with out  asking
