.... they do fittings now for Combi boilers that don't have an electricary immersion built in with them....cool..:D http://wattson.energyhive.com/dashboard/jillandtony :rotfl::rotfl:

....Evacuated Tubes? Nothing so complicated; or dedicated to expense......for info .... http://diykyoto.helpserve.com/default_import/Knowledgebase/Article/View/199/0/optimmersion-with-combi-boilers-central-heating


Bit of a crap day: 2.68 O's; need another 6.08 O's to = June '13. Mind, last year did 13.12 O's in the last two days; so there is hope.... Just noticed that's an average of a/an Hawaii + 1.56 O's a Day!....:j:j:j

3.69 O's yesterday:D

Past June 12 total (462kWh) Should be close to June 13 (505kWh).....if the Sun ever shows today:)

The sun showed its head here this morning...for a little while at least and now its raining. We did just 1.5 O's yesterday and even had to turn the heating on(in the middle of summer) for a couple of hours

Hi

The remark wasn't anything to do with the device .... it was a comment on the example link you provided which, according to their own photograph, looks to have an evacuated tube array to the left of their pv array. Comparing the width and length of the thermal panel to the pv ones it simply looks to be a 20 tubes at 47mm diameter.

I don't know how the tubes are plumbed into the DHW in their particular circumstances, but it certainly suggests the existence of an additional heat source and a DHW cylinder. Considering this, I don't really follow the logic of measuring and 'publishing' a household 'net energy' figure without considering all of the variables ..... at this moment in time we're currently generating ~1500W via the pv, collecting ~1200W from the thermal and consuming ~600W and therefore still have 900W of high grade power to spare and use as appropriate, as opposed to diverting it to an application where low grade energy would do.

It must be remembered that the reason behind most installations of combination boilers is either space saving due to not having a cylinder, the preference of having an unlimited supply of HW on demand or sometimes the worry of frozen water in an unheated loft space. Looking at the link (http://diykyoto.helpserve.com/default_import/Knowledgebase/Article/View/199/0/optimmersion-with-combi-boilers-central-heating) it's pretty plain to see that the solution suggested is to install a secondary heat source 'buffer' (for this read 'DHW cylinder'), which effectively removes one of the major reasons for having a combination boiler in the first place (i.e. space). Long term, the solution described would tie the home-owner into a replacing the combi-boiler on a like for like basis, so it could be much simpler (as well as cheaper long term) to just change to a standard or system boiler feeding a DHW cylinder, with an immersion for the pv, instead of such a complex & un-standard setup .....

I've had all sorts of computer and router problems whilst away on holiday. Solar Edge monitoring failed within minutes of leaving home at the end of May. Most data has been recovered - either from the Solar Edge inverter's internal store or from the Owl monitors. Fortunately the TGM meters don't need a web link for them to work!

I've lost the URL of the MSE forumite's page on PVOutput.org Can anyone help me with this so I can reinstate the page on my browser.

Thanks

114% of PVGIS so far this month, one day to go, maybe I'll smash the 120% barrier, though I doubt it...

4.37 O's at close of play today:D

Well passed PVGIS for June, and 500kWh:T

Hmmm, lucky that I have a system boiler and not a combi; unlucky though 70% of energy costs are for hot water & heating (Gas) ...:mad:

Hold the Phone Groovy; Sunday is going to be a cracker (hopefully, not an Xmas one with SNOW).

And for me it was a/an Hawaii + 0.24 O's...
