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).

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!

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.
