I'm just thinking about the cost etc of
replacing our old wall hung Baxi
boiler.
What are the pros/cons of condensing boilers?
In your case saving 30% plus in gas bills.
Smelly flue gasses and mist,
The fumes don't smell. The mist can be a problem. If not then fine.
To be honest, I don't like the ideas of
newer boilers (fanned flues etc) as
all I seem to hear is "My PCB's blown again
for the 3rd time, and at £150 to
replace its expensive" or "The fan's gone".
Please convince me that new
boilers don't stop working after a few years, and have expensive
maintenance.
These people have tended to buy the troublesome boilers. Fan flues have
been around for 30 years or more, and are virtually standard in all boilers
over the past 20 years. There are Lada's and RRs of the boiler world too.
On this forum you don't hear of the boilers that have gone along faultlessly
for 10-15 years, only the problem boilers. The nature of the group.
I just seem to think that an old boiler will last longer than
a new boiler - and therefore I don't like them!
Older boilrs had little inside them. The point is "new" boilers. "All"
have pcbs inside.
So - potentially could I purchase the boiler
of my choice (and at my price!)
and get a fitter to fit it? Or am I best specifying
to the fitter the boiler I want, and getting him
to get it with his discount?
Specify the boiler you are happy with. There are simple basic heating
boilers around. The new Wickes light cast-iron boilers (Halstead) are
simple, not modulating burners, but you still require pumps and zone valves
outside of it.
Any recommendations for boilers
(including condensing
Non-condensing:
- Heating boiler - Wickes light cast-iron (fanned flue & efficiency of
around 78-79% ) £399 40,000 BTU/h. This is a basic "heating" boiler. 2 yr
guarantee. Can be pressurised.
- System Boiler - The Vaillant Thermocompact RSF 615EH 22.3 - 51.200 Btu/h.
Price £446.50 Including VAT. Efficiency of

act_119.html
This is a "system" boiler with built-in pressure vessel, pump, etc, with an
efficiency of around 80%. 2 yr guarantee on this the last time I looked
Condensing:
- Fully modulating System Boiler - Keston Celsius (fully modulating with
load compensation control) Expensive, but you get what you pay for. Many
happy owners on this ng.
- Fully modulating System Boiler - The Baxi condensing boiler is not bad
either.
- Fully modulating System Boiler - Any Vaillant, but expensive. So a few
hindered quid over, is that such a big deal?
- Non modulating Heating Boilers - There is only the Ravenheat CSI Primary
to my knowledge, there may be more. Can be pressurised or open vented. A
direct swap for many boilers. There may be others. Malvern do a
non-modulating condenser.
The Ideal condensers are having a bad time as they are having a lot of call
backs in the 1st year with BG. BG has stopped specifying them, although
still on their list. Those I have come across have been v good, so it may
be they are doing something wrong with the installation.
Fully modulating condensing system boilers are the better option.
