As a house owner with an old boiler,
header tank and all the rest of it,
I'm terrified about changing the thing
to a "combi". But all the plumbers I talk
to want to sell me one, & did notice that
they only want to sell a Combi. It does
ratherm remind me of the endowment
sales of the 1980's.

The problems asked about Combi's in
this NG must be the highest thread
count here? It makes me wonder what
the rest of the population who don't
post here suffer from with CH and
Combi's? It's certainly enough to make
me never want one. They do seem to
be easy fit/fat profit devices, but
I'm having a cynical day so do excuse me
if I'm talking ****e.

I still don't ever want one of 'em.

Look at my posts on combi's, they dismiss old wives tales on them. Over one
million boilers per year are fitted in the UK. 60-70% are combi's. In a
few years time they will be the majority of the installation base. The
problem with combi's, well it is not a problem, is that people do not fit
the correct models to suit demand. There are high flowrate models around
that will satisfy your needs in the average house.

People go on about them being complex. this is tripe as they as similar to a
basic system boiler inside, with a water section added. Many are just
adapted system boilers. Combi's are very cheap for what they are. So cheap
it is feasible to install two to double the flowrate, zone off the CH system
and provide backup.

Like any other product on the market, there are better makes than others. If
the flowrate meets your needs, then the advantages far outweigh the
disadvantages.
