6 litres am I missing something?

Rinnai

20L/min raised 33°C
780L/hr raised 50°C


WB


25L/min raised 35°C

Could not really care less where its made as long as it works and is reliable.

It will have to run 4 showers customer is dead set on instantaneous hot water, as for mounting not an issue.

Cheers

Phew!

Any particular reason, I normally don't give it this much thought but need to get this one 100% right, I like the separate water heater of the Rinnai and the accurate remote water temperature, but I have never used then on the other hand, the WB is a tried and tested brand which I have never had an issue with.

Am a bit later adding to this post but here goes;

The Twin flow is in two bits so could be easier for a sole trader to lift in.

I have only fitted a couple if Rinnai 16 infinities but they are streets ahead of the Main/WB/Chafferto water heaters.

Having been down to Rinnai's HQ in Runcorn on a training day organised by another forum based Gas blokes association I can say hand on heart that the Twin Flow is a great piece of kit.

Its a rebadged ATAg boiler alongside the Rinnai continious water heater, and it all runa off a domestic gas meter, has Weather Comp cmpaterbility and as an added bonus if one bit breaks down the other half will probably continue to operate. (but I have not checked up on that so you may want to contact Rinnai to check)
