Is it up to 65C yet?

Hi and thanks for the reminder.


Yes, it's been heating the DHW since with the element thermostat set on max, 75C, although the temp shown on the gauge sited higher up the tank peaks around 80C.
I'll probably knock the stat back a notch for the winter months but with excess solar at this time of year I'm not in a hurry.

Still have to sort a controller to make best use of Solar. All in good time!

Hi, I understand about prv, lucky you having more than 3 bar available. :-D
But why a water treatment plant and inhibitor?
I was under the impression you are in Bonnie Scotland, so should have no issues with hard water or limescale?

Oh for soft water like in Scotland, here in bonny Suffolk it's anything but. Neverless I'm consoled by the climate here which tends to help offset the disparity.
Afraid I baulked at installing a salt based water treatment system due to space constraints and cost. Both initial and running, where I understand the latter can amount to circa £100/annum. I settled for an Eddy unit which, while not actually removing limescale, does reduce it's effects being more compact and less costly too.

As for a battery, well, I've one sitting on the drive and just require a cost effective interface to go between it and our home.:)

It's been in operation a month now during which time our gas consumption has dropped to about half of the previous lowest summertime figure recorded of 89 kWh's.
Of the 45 kWh's consumed the majority was probably due to the gas hob, but a smaller proportion perhaps due to DHW drawn off by use of the sink in the en suite, plus some from leaving the pre heat option on the combi boiler operational!
With that now de-activated we'll see what difference might occur when taking next months figures.
At the commencement of this thread I'd thought no further than what car to purchase next. What a journey it's been and continues to this day as we've now set our sights on relying entirely on renewable energy for all our heating, transportation and domestic needs.
If we make it through the coming winter without resorting to the gas combi boiler then we've only to replace the gas hob to complete another step along the way.:)
