I'll get to the point... Have a plumber who has been bought in by my builder to install the central heating system. I wanted a heating cylinder solution to allow for mains pressure hot water through my showers and bath. Was recommended a Megaflo solution. He suggested I get a 250DDDD direct unvented cylinder, combined with a Valliant 637 system boiler. Cylinder installed in loft and boiler in laundry room downstairs. House is a large 4 double bedroom house, with 2 bathrooms (one with a bath and thermostatic valve shower, the other with just the shower downstairs). I have 6 standard radiators, 2 towel rails, and 3 wall mounted vertical radiators in the 46sqm kitchen/diner (each one chucking out 1500KW). Using all this will be 2 adults and 3 kids (under 13).
I have heard conflicting advice about which boilers and cylinders to go for, and upon searching existing posts I cant quite work out what options are right for me. Hoping you good people and professionals can clarify for me please. Specific questions are;
thank you all in advance.

I have heard conflicting advice about which boilers and cylinders to go for, and upon searching existing posts I cant quite work out what options are right for me. Hoping you good people and professionals can clarify for me please. Specific questions are;
- Given I have one boiler, which will be covering the heating and the hot water, is the 637 sufficient, or indeed is it over the top?
- Is an unvented direct cylinder (250DDDD) the correct choice / size?
- Any advice on where I can buy from a reliable online merchant?
thank you all in advance.
