Should I go for a powerful Combi or small Megaflow

[jazz-uk]

Hi

I'm in the process of updating my central heating/water system while extending my house.

I will have 2 baths/2 showers, washing machine and dishwasher.

What would be the best system to go for. its rare that more than 2 sources will be used at any one time, but 2 sources will be used regurarly.

Thanks

Jazz

Most professionals would advise the unvented option providing your mains water supply can provide the required flow rate.

The installer of the unvented should hold the appropriate certificate.

A worthwhile advantage of a HW store such as in a cylinder is the ability to heat it electrically when the combi fails.

Whichever route you go, you must have the mains flow for your needs or anyone taking a shower supplied by the combi is likely to moan.

Storage Combi's - I've heard about those - there the half/half type things that might suit my needs - anyone got more info on these ?

Worcester Highflow 440, Viessmann 333/343 (when it gets approvals) and i believe Alpha do one.

after good advice from some experts on here i went fot the vaillant unistor and boiler well chuffed loads of pressure as my mains is good my shower is now like a power shower, costs a bit more buy but worth it also no tanks in loft and the unistor can be wired up just in case boiler fails
