Boiler swap. INTEC 40GS to Worcester Greenstar 32CDi Compact Combi

Was the basin tap running when you measured the bath?

Otherwise you could have had 10 at bath, but this dropped (to say 5) when you measured the basin at 5. - in which case you only have 10, not 15.

Just checking your method

Thank you for checking! Yes, I opened both initially, allowed the water to run for a few seconds to get hot, then proceeded to place the kettle under each facet

What may have hindered the measurement is that I think that our sink tap has a flow restrictor/aerator and I couldn't get the maximum flow tested (with the sink being limited).

A viessmann100 would be my choice for you bin the worcester idea this boiler would future proof your property and can get a 10 year warranty if fitteded by a accredited installer H2 ready built in wifi really well thought out , and dont forget you can only get out what you can put in , as winter approaches water temperatures in the ground will drop and as a consequence your litres per minute will reduce for hot water .

You fitted many KoP? It's a touch deeper than the offered WB but I agree it's worth it. Didn't realise the HW flow rate was that good and I did the bliming course.

Thank you for the suggestion! Apart from WiFi I don't yet see why it's a better choice.

It's as large as our existing InTec G40 and as powerful
There will be a 10-year warranty on the Worcester too, as I was told

As much as I like the appeal of the technology coming from the country highly dependant on gas (Germany), and therefore knowing a good boiler, I can't see how it's better at this stage

Respectfully how would you know?

The Viessmann has...

Far better modulation 10:1 rather than 4:1 ish.
Stainless steel hex rather than aluminium
H2 ready
ViCare app
Wifi/interweb ready
Extendible warranty to 12 yr
Bolt on weather comp
More efficient
About the same price

I believe the new Worcester eg 8000 is 20-1 like the old 200 which surprised me

 

[gmartine]

I found 10:1 for the 8000 but could be looking at old specs. 20:1 would be deeply impressive.

Ive fitted 3 up to now and another one lined up and all worked faultlessly weather compensation is great for a well insulated home and will definitely cut the fuel costs in my view far better than a worcester.

You asked for advice and we gave it if you choose to not take it then its your proactive i hope it all works out. Kop

I wouldn't know! I meant that I haven't seen any 'pros' posted here. But you have provided some in your response. Thank you!

My point is that if someone had a fully functioning boiler covered by warranty, then they wouldn't upgrade solely based on the features you have provided.
But then again, maybe some people would. Thank you for the food for thought! I really appreciate you sharing the knowledge!

It didn't read like that but thanks for the clarification.

From memory I think the Viessman 100 is a fraction deeper (10cm?) than the WB compact 36CDi which is what you'd need for comparative performance of your existing boiler. As outlined above it is a far superior boiler for approximately the same cost so if you go for the boiler move to develop the stairs/loft I'd make room for it.

Fitting this one at the moment the new 100w 35 kw with built in wifi. Kop

I also thought it was 10:1, for the 4000 and 8000 models.
