Main Eco Compact vs Worcester Bosch 1000

[Deleted member 131795]

It’s a brilliant boiler easy to service and repair worst comes to the worst

It all depends if it’s sized correctly you will be fine (rads) part L came into action September this year so it’s a new thing that he might of overlooked also controls wise are you looking at weather comp ?

i will mention this to him. no weather comp, just an EPH C4 which i think is an opentherm load comp only job.

shaun

am i likely to see significant benefits by paying more for a much more efficient boiler like the new vaillant ecotec plus 826 ?

as mentioned he quoted me £4500 for this install vs the main at £3500

No providing your min output is above your radiators eg let’s say boiler is 5kw min output and your rads are 6kw this is fine

I would also go Main Eco Compact 25kw with EPH Combi Pack 4 Opentherm Controls

hiya pork chop! can i ask why you would do that?

i'm leaning toward that too..

although there is also a vaillant ecotec plus 826 25kw, as a higher end option, but not sure it's worth an extra grand..!

Wouldn't have the new Vaillant. Went on the training course, not impressed.

I have the Eco Compact in my own house - is that enough?

ahh great. the only thing i'm concerned with about it is the lack of wide modulation.. you prob have a huge house to heat but my one bedroom flat is only about 4.5kw and i think it only modulates to about 6.7kw - i'm having a hard time trying to work out if that would make any meaningful difference. other concern is if it's too noisy as it's going in airing cupboard in bedroom.

If it's any help -

I have electronic TRV system, so the load is very minimal. In winter my flow temp is usually running at about 30oc, with very little load. Yes it does cycle as it can't modulate that low (Although even a boiler with a 1:10 modulation probably wouldn't), but it's fine no issue.

It was a trade off of having a boiler with a wider modulation, or Opentherm. I went with the latter and it brought my usage down by 25%.

I wouldn't worry too much about the modulation, I think the big savings are in system controls.

ahh that's great advice thanks very much for that

i will likely just go with the main then. combination of that and the EPH C4 seems like a very solid budget combo.

Yes fitted many Eco Compacts with Combi Pack 4s on Opentherm. A solid choice.
