Thank you dcawkwell
Yes you can go for a combi boiler if you wish to remove the hot water tank. In which case you buy the size of boiler according to how fast you want the delivery of hot water. My choice would still be an atag.
ECX model with the condensate tank to preheat the cold main before it get
to the boiler for heating.
I could find atag ECX 325EC on google search. Is that the one are you referring to? Would mind answering?
Regards
The A325 ECX I think it is. Available via plumb centre although for some reason they messed up in the plumb centre catalogue last time I looked.
Might be worth a call the www.atagheating.co.uk just to make sure although their website looks out of date.
