Hi
I'm thinking of moving house soon and one of the prospective houses I'm
interested in has warm air heating (fairly new house).
Are there any known probs with these systems, are they reliable, are parts
easy to obtain. etc etc
Any thoughts or suggestions greatly appreciated
Jim
PS Also, do these systems provide domestic hot water as well?

A fairly new house with warm air heating.... Thought that was a 70's thing,
well from my experience they produce a very dry dusty heat, you can be
boiling hot near the outlets but freezing cold at the other side of the
room, don't know of any probs specifically with them tho.

The biggest problem is that prospective buyers will have doubts about it
when you come to sell, just like you do.
We replaced ours with conventional rads a while ago because we were
extending and it wasn't extendable.
You definitely want Mod AirFlow (assuming Johnson&Starley) or an equivalent
variable fan-speed system. As it's a modern house this is probably standard.
Ours had a separate gravity-fed "Janus" heater and primatic DHW cylinder,
also very 70's.
Plusses are that it's very reliable; there's nothing to rust or leak. Also
the house heats up very quickly and you don't lose wallspace to radiators.
J&S spares should be no problem - don't know about other makes.
Minuses -yes it's dry,dusty and a bit noisy. Also you'll probably find large
gaps at the top and bottom of all doors, and you have to clean the dust
filter regularly.

It's already installed, so that's not an issue. I suppose you're going
to say that they blow carbon monoxide all over the house, or that flames
will come shooting out of the vents ...

He will.

yes the older models could pump c/o around the house....less and less gas engineers are requalifying to work on warm air as there is no money in it...the goverment is pushing to stop the sales of less efficiant c/h systems and this is putting the final nail in the coffin for warm air....however there are folks that like warm air...its possible to intall a wet ch boiler that sources heat to a warm air unit via a special heat exchanger...expensive and Ive never saw one installed in the uk ..

Odd. I have a CH boiler feeding half a dozen fan convectors...

That is how you do it hese days.

Only if the heat exchangers was holed. And as the modern exchangers are
stainless steel highly unlikely.

less and less gas engineers are requalifying

A service call is a service call. The gas controls are the same as boiler
controls.

the goverment is pushing to stop the sales
of less efficiant c/h systems and this is putting

Total ********!!! There are some highly efficient warm air systems. J&S
have a condensing box that fits in a conventional flue adding efficiency.

..however there are folks that like warm air.
..its possible to intall a wet ch boiler that

I have seen lots. Whole housing estates and tower blocks had Copperads
fitted. There are copper coil air handling units around, heated by boilers
which heat the cylinders too.

You really should find out something about forced air before you prattle
tripe.

It's how air handling units heat air (other than electric or heat pump
jobs). There must be many hundreds of thousands of them, you can't get
out much.

Good systems.

Are there any known probs with these systems,

No.

are they reliable,

Yes

are parts easy to obtain. etc etc

Johnson ad Starley provide all parts. Most of the gas parts are common
boiler controls.

Any thoughts or suggestions greatly appreciated
Jim

Keep with it.

PS Also, do these systems provide
domestic hot water as well?-

Some may have a gas circulator in the same casing to heat the hot water.

The biggest problem is that prospective
buyers will have doubts about
it when you come to sell, just like you do.

Adapt it to bring in fresh air. Then it is a forced air ventilation system.
They also cool in summer by drawing in cooler outside air.

We replaced ours with conventional rads
a while ago because we were
extending and it wasn't extendable.

You can have a split system air/rads. most are extendable. It is just
dutwork.

You definitely want Mod AirFlow
(assuming Johnson&Starley) or an
equivalent variable fan-speed system.

Yep.

As it's a modern house this is probably
standard. Ours had a separate gravity-fed
"Janus" heater and primatic DHW
cylinder, also very 70's.

Can be on a quick recovery coil cylinder. The Janus is very reliable.

Plusses are that it's very reliable; there's
nothing to rust or leak.

Yep.

Also the house heats up very quickly and
you don't lose wallspace to radiators.

Yep.

J&S spares should be no problem - don't
know about other makes.

Only J&S unless you go American. Lennox are available in the UK.

Minuses -yes it's dry,

A humidifier (spinner) can easily be installed, an controlled via a
humidistat.

dusty

Electrostatic air filters are available that are recommend for asthmatics.

and a bit noisy.

New units are very quiet, also the cupboard can be further soundproofed
quite easily.

Also you'll probably find
large gaps at the top and
bottom of all doors, and you have to clean the
dust filter regularly.

Electrostatic filters have a dust trap.

Oh this idiot again. There are no safety issues with warm units in any way
whatsoever. Are you corgi registered? How do you make a living!

Matt, do you mean warm is dangerous too? Figures. Amateur myths.

Are you

snip senility

Im more qualified than you.....

also ive attended a few fatal incidents regards WAU...i think you should have your licence pulled if you have this sort of attitude towards a well known safety issue in the gas industry

Jim all I can say is listen to Doctor Drivel. The system's are fine with excellent backup from Johnson & Starley. Mine is 20 years old and has a problem that is currently being fixed with off the shelf parts (could you imagine a 20 year old wet system still being fully servicable with off the shelf parts). Do not listen to scare mongerers most have no experience with these systems so they don't like them (I know from talking to local plumber's). Just go for it don't be put off by warm air heating.
