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 ...

Good systems.

No.

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

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.

a while ago because we were

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

(assuming Johnson&Starley) or an

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.

nothing to rust or leak.

Yep.

Yep.

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.

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.

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 ..

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

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

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.

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.

Also the use of a garage or outhouse located oil boiler with a centrally
located indoor fan and heat exchanger serving the ducting distribution is
not uncommon on my patch. (Afos is the make which jumps to mind)

That is true: Where Aircon does go in these days its more about
recirculationg and cooling air with refrigerating cassettes rather than
full aircon.

Personally a fully modern house could and maybe should have very tightly
controlled ventialtion and heating: Like Drivel always goes on about...but
the cost of doing it with no standard off the shelf bits tends to exceed
the cost of simply shoving in a bit of air cooling in summer...

At some level its all a compromise. My hot air blowers cold indeed have
cold water going through them - sloightly refrigerated water - in
summer...but he danger would then be condensation...

Neither is heating, then. Depends on whether you like comfortable

It is needed, unless the house is superinsulated, and built to passive solar
principles.

Depends on whether you like comfortable
temperatures at all times.

With adequate design, insulation, thermal mass (this helps) and ventilation
a/c is not required at all.

From what I've seen of your posts so far, really don't think you

You strike me as someone who has read quite a bit on the subject but
lack practical experience.

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.

Please sort your quoting out. I was replying to Drivel, not you. A good
way of doing this would be to read uk.d-i-y) direct rather than through
