But there was something on TV the other day with a new build eco

blown air electric central heating?

Now, as long as we take 'renewable' energy as carbon neutral ...

Beware the Baxi recommending plumber IMHO.

Some heating engineers seem to like to install only one type of boiler
(presumably familiarity and ease of spares, perhaps bulk buy incentive) so
their personal recommendation may have a bit of self interest built in.

We had a WB combi installed around 2006 in a 3 bed semi and AFAIK it has
never (or very rarely) been serviced. Still going strong last year again
AFAIK.

Our current WB has been in over 5 years, again no service (trend here?)
and so far is running fine.

Our daughter had a new Baxi combi in her house on the recommendation of
the plumber around 2007/08 and again didn't have it serviced. It failed a
few years back and had to be replaced. No service, no warranty so that is
a risk.

On purely my personal experience I would prefer WB over Baxi every time.

Received wisdom from this group in the past has been for WB or Vaillant.

Which? Rates WB highest at 86%, followed by Viessman at 83% and Vaillant
at 80% (which is also rated as the engineer's favourite).
The Baxi brand score is 54%.
Which? isn't always 100% accurate but this may at least give an indication
of the relative quality.

Recommendation: ask a different heating engineer!

Cheers

Parts alone are likely to be around £2,500 if you go for quality kit.

I did a complete refit here about six or seven years ago, and did a
conventional boiler and cylinder replacement. I went for a system boiler
with unvented cylinder, fully upgraded controls, with weather
compensation and external temp sensor. Fitted / changed three new rads.
Added whole house phosphate dosing scale reducer, whole house blending
valve, split the heating into two zones. Total parts for that came in at
just under 3K when allowing for a couple of hundred I got back for
weighing in scrap and ebaying the old programmer, stats, and a reclaimed
gas valve.

Needless to say, if you need to add labour, that will add significantly
to the price!

We're (still) looking at a new boiler so I'm watching with interest but
thought I'd flag up the issue of guarantees: they vary enormously but
it's hard to judge their value. Eg Vaillant offer on some boilers 10
years if fitted with a "protection kit" and serviced annually.

The usual reccomendation is WB, which I've just bought, and it seems
good. Only ~9 months old, so no idea of reliability. Soempeople like
Vailant, but I had one a number of years ago, and never again, and my
Mom's house had a Baxi, which really didn't seem to last well enough IMO.

Is there already an Immersion Heater Power supply?

It's still lawful to DIY if you are competent. But I'm not going to do
ours as I'm not confident in my soldering and it'll almost certainly
need a new pipe from the meter.

What has changed is that a new boiler is now notifiable work, like Part
P electrical work. I suspect rarely done. Our council's building
control don't even list a price for signing off a boiler as they do for
a rewire.

Carbon capture doesn't work, nor is it likely to.

The beauty of transferring CO2 production to a central point is that it
can then be used for carbon trading. As I see it, if the ruler of some
benighted (but large) third world country is willing to trade his
citizens' access to electricity for cash in a Swiss bank account we can
'buy' that country's allocation of CO2 production and take our CO2
production off the books. It no longer counts against us! All for
money.

Okay, Ive got some more details about my daughters boiler. Its a WB 28i
Junior That according to WB is 15 years old.

Currently itll only make HW when the thermostat is calling for CH and
often not even then. Frequently of start-up you can hear the boiler kettle
get and the locking out (almost certainly due to over-heat). I witnessed it
do this and couldnt detect any vibration from the pump whist this was
happening so I suspect that sometimes the pump isnt starting.

Also the HW temperature is hard to control swinging between too hot and too
cold.

To me it sounds like a dodgy pump and maybe a dodgy flow switch too but I
dont really have any first hand experience of combis. Given its age, is
it worth a piece by price repair or should we cut our losses and just go
for a new boiler? (Not a Baxi).

There *does* seem to be some sort of magnetic filter in the system so
whilst slugging might be a factor, Im not sure its a major factor.

I would always repair if possible. If it is the pump then often you can
change just the pump body.

You can often get parts on eBay as so often boilers are scrapped when
fully working, or with a known fault.

Sounds like it'll be more than an order of magnitude cheaper to repair, if you diy anyway. If not still far cheaper.
You might start with:
Pump not running: monitor electrical feed to pump.
HW not firing: monitor cyl stat output
etc
Water going hot/cold: one cause of this with combis is demand falling below minimum boiler output. Increasing water flow resolves.

Carbon capture doesn't work, nor is it likely to.

It does work when its captured as limestone etc,
the problem is that its not economic to do that.

Same guarantee offer here (10yrs) from local supplier/installer

wouldn't get another one - there's an annoying interaction between
the HW and CH that makes for showers running hot or cold for a while
when starting up, no probs in summertime with no CH demand. Even the

well in summertime. It's also more noisy than I expected, which

Our old combi showed that symptom when the flow switch started to fail,
but of course if you suspect the pump anyway it could be intermittent
flow in the heat exchanger.

Renewable has never been cheap despite being sold as the sun and wind
are free. It's much like the myth that the government are providing the
money for "green" subsidies.

There was nothing about tidal in the interview I listened to but with
the Extinction Rebellion protests every radio station had someone from
the loony green community.

As for UK tidal it's not just cost but the practically/efficiency and
the long term damage to the ecology.

Speed, the auto-contradicting senile sociopath, blabbered, again:

I fail to see how anything that incorporates permanent contact
with, or existance near salt water can be termed reliable, unless
it is built to nuclear engineering standards, in which case ...

I visit Worthing regularly and the way the sea scours away
and corrodes anything metal (or timber) is awsome.

And yet some of the longest bridges in the world survive fine.

ROTFLOL! In auto-contradicting mode again, you abnormal senile pest?

Presume this is sarcastic?

Most people in NZ don't seem to have heat pumps, most don't have any
heating apart from electric fires/fan heaters/radiators.

Houses are very poorly insulated as well.

I have a family member living there and have also extensively travelled in
NZ.

Of course, some of the new builds may be different but the one I know
about wasn't built to include a heat pump.

Its looking like my daughters Worcester Bosch boiler needs to be
replaced. Recent visit by boiler man resulted in firstly a
recommendation for WB care plan as it would probably be cheaper (point
in his favour) but apparently the boiler is too old for this. (Havent
checked the veracity of this).

He suggested a Baxi boiler which I dont hear much about here. He was
also rather scathing about the reliability of WB boilers.

Anyhoo, what are currently regarded as the best or €œbetter€� combis
these days?

The usual recommendation seems to be Vaillant, WB, and Viessman...

As an aside, I would be tempted to subsidise an €œupgrade€� to a
non-combi and pressurised HW tank + immersion. Any ideas how much more
this might cost compared to a combi?

Parts alone are likely to be around £2,500 if you go for quality kit.

I did a complete refit here about six or seven years ago, and did a
conventional boiler and cylinder replacement. I went for a system boiler
with unvented cylinder, fully upgraded controls, with weather
compensation and external temp sensor. Fitted / changed three new rads.
Added whole house phosphate dosing scale reducer, whole house blending
valve, split the heating into two zones. Total parts for that came in at
just under 3K when allowing for a couple of hundred I got back for
weighing in scrap and ebaying the old programmer, stats, and a reclaimed
gas valve.

Needless to say, if you need to add labour, that will add significantly
to the price!

Just out of interest (at the moment) would the cost of replacing "like for
like" be anywhere near that?

That is, removing an existing combination boiler and installing a new one
in the same location.

Given that all the services (gas, water, electricity) should already be
there I assume that the labour involved is significantly less than a new
install or a full upgrade?

https://www.plumbnation.co.uk/worcester/greenstar-cdi-compact/

is currently listing WB boilers starting at £1099.24 including VAT so
rashly assuming the labour would be 2 days that might bring the whole
install in under £2k.

There was a tiny bit on heat pumps on the radio today. It wasn't on
saving energy but on the cost of running.

The general conclusion was that if you heated your house with mains gas
you would probably save no money by replacing gas heating with a heat
pump. The cost of running a heat pump with electricity plus the gain
of the pump is negated by gas being 4x cheaper per unit.

For other forms of domestic heating the comparison will be different.
