So in short your saying fit a lower jet and set the pump psi as per book run it on the analyser ( little bit of tweeking) and im going to be good to go ?

Its already on the lowest jet possible = 25kw

Hello all, Is it possible to De-rate a Greenstar Danesmoor Riello 25/32 RDB 2.2 ? Long story short it appears the boiler is significantly over rated, I'd like to reduce it to 18kw ( oil reduction is approx 1L and hour less consumption). Would it be possible to find the differnet parts between a Riello 25/32 RDB 2.2 & Riello 18/25 RDB 2.2 and de-rate it that way or is it a case of a whole new burner and or boiler ? Ive checked the physical side and the dimms are the same, checking the Riello parts list between the 2 there are some differnet parts obviously but the core parts appear to same across the range. Of course the work would be done by an OFTEC reg Engineer we use. Thanks for any info / thoughts. FLY

Certainly no expert but I think the rule of thumb is 100m or there bout is the max length. FLY

Thank you.

Hello fellas, Could someone advise me where a System Volumiser would be located please. Would it go on the flow or return ? Many thanks, Fly

I was sure it was 10kwh previously hence my post.

Had anyone noticed the Tesla Power has had a software upgrade which has resulted in a 3.5Kwh increase in capacity taking it fro 10kwh to 13.5kwh.I wonder how much reserve they actually have? Fly

You still get paid your Generation Tarrif from what I read.

I actually worked this out last night based on year so far. I had to have Solar as part of my New Build so I went Medium size due to DNO restriction of 5kw Max export. ^.2KW system. Using Tesla Tarriff I would be currently £80 better off YTD. That said I dont export much as we divert spare to the immersion heater and doing heavy use items ( washing / dishwasher) due the day around the Solar Production.No dounbt a Power wall would remove the peaks and troughs. Buying the Powerwall would not be a good use of £8k, that said as Energy prices riase and Technology improves there will be a time in the future where its worth reconsidering.

He are my integrated panels. Had many comments on how much better they look than 'on' roof system.

For Ref I have a 6kw System. In April :- Produced 577 kWh Self Consumption 480 kWh Exported 97 kWh I have an immersion diverter that uses spare generated Electricity to heat DHW. I ran the boiler once that month for DHW. We time washing and dishwasher running to solar production too. May :- Produced 913 kWh Self Consumption 655 kWh Exported 258 kWh Boiler run 0 times for DHW

Plenty of lube on it to allow free movement eased my troubles.

Tom, I still cant see the reason to keep them powered on all the time. Mine are off by default and never go into Calibration mode. Im confused why you would want them open. For instance if the UF was to come on in one room the fact they are open it would heat all the other rooms aswell.Unless im missing something you are defeating yourself at step one. Happy to debate this with you and hear your opinion as we all have differing goals. FLY

I have those Acutators, my wiring system only powers them up if that Zone calls for heat. Question why an acutator would always be on, seems counter pruductive. Fly

I can confirm these work on Heatmiser equipment as I have them at Chateaux Fly. Out of the 12 I had, I had a rough one that did alsorts of daft things. Not closing, not opening etc. Sent it back for a replacment problem solved. I can also confirm mine are normally closed even after the power goes off and the call for heat ceases goes off. Fly

Where in the world are you, I have a thermal Camera which could help the issue. We are currently T4 so movement isnt possible, but going forwards after that.

Thank you.

Can anyone confirm the Condensate Temp for an oil boiler please. I see gas is 55c and a lot of pages seem to mention oil is the same, but there are the odd pages that quote 47c as the condensate temp.. The manual makes no reference to it nor does the manufacturers website. Of course I understand the lower the return temps the better. Thanks as ever. Fly

Between the flow and return on the underfloor heating circuits, not to be confused with the manifold flow and return temps as thats blended water from all the circuits.

Heatmiser Thermostats and a Realiance Wiring Centre. Acutators are 230V so wired. But yes they do work. There was an update last year to resolve the Heatmiser issuse I understand. FLY

I have the Salus Auto Balancing Actuators there work really well. I have 12, that said one has gone faulty and is been replaced. They do seem to miss the 7c differential on msystem and settle around 10c. Works with Heatmiser too. Id recomend them. FLY

Evo Home by Honeywell do both im sure as do Heatmiser ( not 100% sure on them though).

The PV doesnt produce that much in the colder months, we put everything into the DHW tank and some days it cant bring that to up to a decent temp if its low cloud on little sun. As for Oil usages I suggest it will be 900 - 1200 L depending on the Winder Temps. Im exploring the option, A there is an RHI incentive B Borris's Carbon Plan. Thanks, FLY

I was with you all, but those VortexAir's are close to £10k. I should add I have 6.2Kw of PV Solar on the Roof too.
