Re: New Boiler (with automation inclusion)

[Robin Edwards <robin@xxxxxxxxxxxxxxx>]

I don't believe so, but it does depend on what you mean.   We have two
combis (sounds crap straight away), one in our house and one in our
holiday cottage (better).  Both are Worcester Bosch, the one in the
house is new (about a year old).  It is a Greenstar 42CDi, which runs 7
rads in 6 rooms and underfloor in one room which was an extension added
one year ago when we also changed the boiler.  It is controlled by a WB
controller that is wireless.  Shower is great, we have a HG Raindance
Air head on the shower.  I prefer the shower so cant comment on bath
fill times.  According to WB website it delivers 17.2ltr per min.

I would say we are happy and its miles better than our previous showers
(an electric one and then one on a combi that could do 9ltr/min).

The cottage boiler is 11yrs old and probably time for upgrade so wont
comment on that more.

The one problem we have had is with the controller. But that is down to
the fact we have some solid stone walls in our house that are 18" -
24"
thick so if you move the controller from room to room it can call for
heat and the boiler wont see the signal.

The thing I can't do and would like to is to introduce a second form of
heating (solar?) to drive the cost down but you can't do that with a
combi to best of my knowledge (no tank).
