Not as impressive as lucky Legoman's amazing 3500 kwh year to date yield

A few weeks ago I was hoping I might make 3600kWh but, after the dire weather round here, will be well happy with 3500kWh
Made 5.56kWh today
Gen meter says 3455.4kWh so I need about 3kwh av per day:D

My 25mm rising main is plastered into the wall near to the chimney.

The water coming in through it is so cold it creates condensation and the dampness damages the decoration of the wall.

Any thoughts of how much heat it is transferring to the tank in the loft and how it might be insulated?

I get the same problem with the water that feeds the toilet cistern, I do remember from the 1960s that Canadians used to wrap their cisterns in a furry cover - but perhaps that was more of a fashion statement, than condensation preventer?

Hi

The only thing that I can think about the water pipe would result in a degree of redecoration, but if it's already causing a problem then it could be worth it. I would look at the possibility of channelling around the pipe, wrapping the pipe tightly with something like clingfilm, then filling the channel with a fire resistant expanding foam and then resurfacing with plaster/filler. You would need to check that the foam wasn't amonia based or contained anything which would have a long-term effect on the copper pipe.

Easiest way to measure the heatloss would be to measure the temperature rise in the water from ground level to tank entry, but I'd guess that it wouldn't be too high.

Regarding the cistern, I've seen mention of lining the inside of the cistern with wetsuit-type material which creates a temperature gradient between the water and the ceramic, thus reducing the external condensation .... however, we find that simply running a dehumidifier reduces the condensation considerably, we still get some when the ground temperature is low but not to the extent where it runs and drips.

Thinking about it, unlike traditional homes in London, out in S.Essex only the hot water passes through the storage tank in the roof, all the cold water (in this bungalow) runs behind the skirting board, more or less buried in the screed of the floor[ :eek:.]
So the rising main is only supplying a pipe full of cold cold water when someone draws off hot water.

Smashed yesterday's result with a monster 1.8. Nice week of sunshine only 4 days away. Why is it always 4 days away according to the weather forecast, and why do the little sunshine symbols change to grey clouds when they get to 24hrs away? Ho hum!

Mart.

I woz robbed. Well the nice sunshine arrived today, but Friday's promised sun changed to grey clouds by the morning forecast. Now Monday and Tuesday's sunshine has been replaced by grey clouds and rain. Fibbing weather forecast - what you gonna do?

Got a 9 and a 2.4 today, so not bad.

Next door still vacant and wifey off volunteering all weekend, so time to dial up those speakers again, maybe add some CCR & AC/DC to the GnR today (I'm working my way through the alphabet - the fun way). :T

Mart.

Need 50kWh to break 3500 for the year with just over 2 weeks to go

Not as impressive as lucky Legoman's amazing 3500 kwh year to date yield but today we have:

We also hit 3200 kwh generated to date, which has exceeded our 3131kwh forecasted annual estimate.

We have another month now of most likely paltry generation before our installations first anniversary but we look to be slightly ahead in terms of what our expected yield was.

It has been really useful to see what people actuals versus planned generation has been. Glad we took the leap of faith to go ahead a year ago without so much anecdotal data and knowledge gained through sites like this and PVOutput

Well said Cavemanu: This thread must be better than 'sliced bread'. My Stats todate are: I have 26 days to go to the 1st years anniversary; currently 375.5 above forecasted expectations, which equates to 18.4% above. Currently I have earned £1,225.54p. tax free; saved 29.2% on usage of electricity (not included in the above £ figure), based on last years usage. Without the help of many contributors within this thread, I would never have worked all that out; I will not name, in case I leave someone out; thanks to a great bunch of people on this thread.......:T:T
Oh, sh**e, not used to giving speeches on threads, forgot todays numbers, 6.2 kWh....:rotfl:

Best day since 14th October, a barnstorming 16.1kWh to banish the blues of the last 5 days: 5.5kWh in total(!) between Mon-Fri. No cloud, mist, fog, rain or eclipses

Got up just in time to override the boiler's hot water program this morning and the ImmerSUN did it's thing, directing 11.348kWh into the hot water tank via the immersion, a new record.

It also nudged us past October's PVGIS estimate and we're now 6.5% past it, 4 days to go. Forecast doesn't look too promising though.

Seems the sun has shone almost everywhere today,I racked up a nice 11.5 today,think the wife used 99% of that doin the washing,cooking,drying,dishwasher(she missed the last 1% in between appliances being turned on and off).....and after the dismall weather of the past week means i've got some clean underpants...yah:T

I know the weather's been pants but that's too much information :rotfl:

Hi

Dizzy height of 0.99kWh today
