Alternative to a Worchester 400 highflow

[gingalig]

Hi, I have a customer that has a high flow 400 in a fairly large bungalow and it’s on its last legs, worchester have stopped making parts for it so time for a replacement, the customer doesn’t want a cylinder and would prefer a wall hung boiler but I’m getting a bit lost in choices, I’m conscious that they don’t want to downgrade anything that they already have, the 400 has a flow rate of up to 20lts/min and the alternatives that are wall hung seem to come in at around 15lts/min. Any suggestions? and would the difference in terms of a shower be noticeable. ? I have suggested a high flow 440 but they don’t seem very keen. Thank you in advance for any help/suggestions.

Thank you, the Viessmann looks pretty well suited and I’m not sure how I managed to miss the Vaillant, I usually work on smaller scale systems, I’ll put the choice between these and the 440 to them.

Viessmann for me but you will require a hand to mount

Not sure. I haven’t removed it yet.

Fitting the new flue is not easy.
You have to get three bolts on from inside the boiler.
Which means taking most of it apart then you need to get your hands into rediculous places that you can't see so feeling around like a blind man.

I've not fitted a storage combi, is the 20l/m genuine and are they really capable of supplying two bathrooms with ease ?

Until the store has been used then it just works as a normal combi

same as an unvented cylinder then least with a storage combi you will have some hot water

The house in question , I mean is there a bath ? Mixer showers , electric showers ,,, Depending on what's in the house would let u know if you'd get away with a combi that doesn't have any storage but still has 17lpm flow rate , wall hung Worcester cdi42kw or vogue 40kw both around 17lpm he but no storage of hw,
