Hi,
I'm looking to replace my boiler (vented system currently). 4 bed house, 1 bath/shower (soon to be expanded to 5 bed, 1 baths, 1 shower ensuite). Only 2 adults 2 kids, rarely shower at the same time, if at all. Also going for water underfloor heating during the renovation. The boiler will be moved into the loft. The house has plenty of mains water pressure.
I plan to have a high end shower, so plenty of water, body jets etc. I'm also a sucker for efficiency which is why i've discounted a unvented system - i don't like the idea of paying to keep water hot.
I'm considering either the Alpha FlowSmart 50 or the Vaillant ecoTEC Plus 938. I like the idea of the FlowSmart pre-heating the water, and the potential to use a Solar PV immersion on it too, however the relatively small 50Ltr tank makes me wonder if it will last the length of a good shower.
Of course flow rate is the most important, will the FlowSmart give that much better than the Vaillant?
But is the extra cost worth it ? Over £1000 for the FlowSmart on top of the 938.
Are there any other combis i should be considering? Perhaps Worcester 42Cdi?
Thanks,
Elliot
