Yup, we have one and our monthly energy (gas and electricity) DD is £47,
this is using electricity for cooking, mini-dishwasher, washing machine,
tumble drier in winter. Two bedroomed late Victorian terraced house with
good double glazing.

We use a small table top oven for baking and low energy lamps and tend to
keep the heating below 21 C in winter. Heating went off about 2 weeks ago
but we are in the nasty South :-).

You can have a condensing boiler with stored hot water too. Best of both
worlds, since for most it's heating the house which is the major cost, not
hot water. And, of course, a non combi is likely to cost less in repairs.

With a properly insulated storage tank, it only needs heating when it
looses enough heat to need this. Or when enough stored water is used up to
require it.

had a repair chap in the other day to change 3 way valve and actuator.
He reckons I could save £200 pa on my gas bill by changing to a combi
boiler.
My system is a condensing Vaillant boiler with hot water provided by hot
water storage cylinder.
Don't like the pressurised systems, seems to many problems highlighted
on here.

There have been a few people killed by systems with vented header tanks.
I don't recall many being killed by pressurised tanks.

I guess they tend not to be over bedrooms!

A vessel with virtually incompressible Water sounds relatively safe!

Never seen anyone have any problem with
ours and almost all of ours are done like that.

It isn't hard to do a fail safe system.

I don’t recall any being killed by pressurised tanks myself.

The pressure isnt enough to kill anyone.

What was the saying? He would, wouldn't he?

The chances of a repair man knowing exactly how much hot water you use and
how is near zero. The chances of a repair man trying to sell you new gear
you don't need rather much higher.

Not had any problems with mine. You might find it difficult to find one
which isn't these days.

How did he make his "calculation"?

Did you tell him what your existing gas bill is? What percentage
saving does this represent? Don't include the standing charge.

Using some rough figures, £200 would buy me around 6500 kWh of
gas which is equivalent to a constant consumption of about 740 W,
which is somewhat high for cylinder losses.

You also have to add in the costs of the new unit and fitting (unless the
old is worn out), written down over its expected lifetime. Likely more
than 200 quid a year.

Nah, you won't save that amount. If your existing system was non-
condensing, then £200pa is much more likely.

obviously the hot water tank would not be pressurised, it would not
exist in a combi condensing system. Only the rads etc.

I know that and you know that, but as posters above say, when there is
the possibility of a sale its all about money.
