The best one will be a properly specified one. I would advise sitting down (over a pint) with your gaffer and have him talk through the options. There are a many ways to skin this cat and you'll learn a lot more face to face.

Have you done any of this at college?

hello and thanks for that, my name obviously fooled you, im a gas safe guy with 15 yrs trading alone..but,,, still learning:wink5:. im just after ideas whether a 15 lpm combi ?? megaflow probably not as flow crap or maybe accumulator type system???

most reliable for u would be tank in roof and heat only boiler if low pressure/flow rate and pump if needed. old ways often the best. Or if they want some lateral thinking a 30m water tower in the garden and you can use any system u like

I agree, even toilets are tank fed at the moment

Unless there is an overwhelming need to get rid of the storage tank, stick with tank fed low pressure system, and pump any part that you need to (like maybe the showers). Nothing much to gain from changing it, and plenty to lose.

as an after note how on earth do you think a 15lpm combi can feed 3 bathrooms!!!

Could put a break tank in & pump the whole house if they have the money !!
