Hi all

More Qs on the kitchen refurb project for anyone using kick space heater(s).

ISTR previous posts (long ago) complaining about the inaccuracy of the
stated output figures for kick space heaters.
I have a single storey extension for a kitchen (5m x 3.6m x 2.4m ceiling
height) and anticipate needing 2.3Kw heating capacity for cold start up.
Cavity walls (3 external) with some polystyrene cavity insulation and
pitched roof which will be insulated to 300mm.

The largest heater is the 800 model which (in normal mode) is a little light
on this figure.
Does anyone have experience of these to advise please?
Should I be looking at 2 smaller heaters to achieve the heat requirement and
spread the heat? I am reluctant to do this due to cost and also as I have a
pre-routed 15mm supply - not sure if that will serve 2 heaters.
Another Q is regarding noise - is this an issue, or are they reasonably
quiet in operation?
Finally, do they have built in stats for fan control, and if so, how would
they go on with 2 units in the same room?
Any other gotchas relating to these heaters?

TIA

We have one but I'm not sure that I can offer much useful advice other than
to try it and see. Ours does a good job of warming our kitchen and with the
fan on low, the noise is very unobtrusive. Indeed it's easy to forget it's
on. On high it warms the kitchen quickly but we're well insulated and
really don't need much extra heat. It is a bit noisy then so you wouldn't
want to leave it on that setting for long periods, just for a boost.

requirement and spread the heat? I am reluctant to do this due to

Given the high cost I'd be tempted to just try the one. If it isn't adequate
for the coldest days, supplement with a conventional electric kickspace
heater.

reasonably quiet in operation?

Ours doesn't have a stat but I guess there's no reason one couldn't add a
wall stat to control the power supply.

Any other gotchas relating to these heaters?

Not so much a gotcha but a feature, they seem to have a pipe stat that stops
the fan operating if it's in heating mode so that the fan won't run until
the CH kicks in. The fan will stop automatically when the heating turns off
at night.

Thanks for that Tim.

A couple of other things spring to mind:
Are they simply free standing - held in place by plinth grill mounting?
Do you tend to get very localised heat, or does it spread well?
How big is your kitchen and are there obstructions like an island anywhere?

Dunno. I didn't fit it. ;-) What I do know is that they're fitted with
flexible tails so that you can pull the heater our for servicing/repairs if
necessary.

Seems to spread well.

No obstructions but our kitchen is open plan with a dining lounge area so
it's hard to compare sizes.

I am also planning one and found the makers brochure wasn't clear at the
time about a pipe stat. I asked Myson and they confirmed that the fan
switches off if the CH pipe goes cool

I reckon that part L makes a room stat mandatory, just make sure
it can cope with switching the load of both fans.

Any other gotchas relating to these heaters?

Make sure the plinth on your units is deep enough. My kitchen
fitter had to lift mine an extra few mm to allow enough clearance
(after floor tiling).

I fitted one (the 500 model) roughly ten years ago and it has worked
faultlessly until last year when it just refused to work. Normally the fan
thermostat only kicks in once the central heating is up to a reasonable
warmth.
I don't see why you could not fit an external stat to the supply cable if
you so wanted.

I had the false cupboard base out last week and noticed that the flow pipe
was hot but the return was only lukewarm so probably an air lock somewhere
in the return pipe which is going to be a bugger to get to (carpets &
floorboards up) - grrrrrr.

My kitchen is roughly 5.5m x 4m and I notice the difference in temperature
now it's not working, even with the heat coming through from the rest of the
house so now that it's not working I realise that it was efficient for the
space at the time.

I have just bought an electric only model from Ebay, new, for £20 so may try
that in it's place.

Aren't you rushing into an assumption about an air lock?.

What about - partly blocked heater matrix in the Myson? Lockshield needs
opening up a bit?. Pipe needs flushing?

I would be inclined to try and link the flow and return with a piece of
pipe, remove the Myson and flush it- and run the heating through the pipe to
see if it flows properly. Why should it be an air lock?

Thanks John, I'll try that at the weekend and it could well save me the
hassle of fitting another.
ps: Note to the Scullster, I screwed mine to a couple of short pieces of
melamime to raise it by 20mm or so as it made it easier to cut the slot in
the plinth without a slim sliver that would probably snap when refitting the
plinth. It is not fixed to the floor but when you screw the faceplate/grill
on it holds it in place well.

The noise from the unit is unobtrusive in slow speed but quite noticeable in
high speed.

The other thing I have found is the fan only option for summer use is a
waste of time for me but it may be of some benefit in a smaller room.

I guess the Myson is the lowest point in the heating system - therefore
scope for heavy gunge to settle.

My thoughts include: Remove - flush. Drain gunge from pipes. Add Fernox.

Recognising that others who have replied find these to be quiet I find
ours to be noisy even in low mode. It's not the sort of noise you
immediately notice but when it stops I find it's such a relief
IYSWIM. It is effective though, it's our only heating in a 4m * 3m
kitchen (a 600 wide model) and it does the job well.
Ours is connected to a room stat which, from memory, is provided for
in the wiring connections. The heater has permanent power and the fan
can be turned on even when it's cold although I'm not sure why you'd
want to. The heater has a pipe thermostat inside it and turns the fan
on automatically when the pipe is hot enough and the room stat is
calling for heat so it starts up a little while after the boiler
starts and carries on a little while after the house heating goes off.

There are a couple of downsides to know about:
1. Noisy
2. The main switch has on/off/auto settings and sometimes ends up in
the off position because it's been knocked which leads to a cold
kitchen.
3. It allows the same amount of water to flow through it whether it's
on or off so when the room is up to temperature it's acting as a
bypass which seems a bit wasteful to me especially as ours is on a
longish run of its own.

The "heat carrying capacity" of the various pipe sizes is well
documented although I don't have it to hand - google this group I'm
sure it's been discussed, if not I know that the manufacturers list
it. At a guess though I can't see why a single 15mm pipe wouldn't be
happy supplying two kickspaces - they're not that powerful.

I have found them to be very good space-saving heaters. In my experience
the flexible hoses block very easily. I guess the flow rate through the
matrix is fairly low and it is at the lowest point in the system. Things
are very much better now that I have managed to get the system quite clean
but still I find that particles migrate there and stick and quickly build
to a point where heat output is noticeably reduced. The standard 15mm
flexibles have a very small bore; are there any larger ones available I
wonder?

Connections are provided on the terminal strip for an external thermostat.

Had a bit of a bonus this morning, my winning Ebay bid of £20 for an
electric model 500 turned out to be the hydronic model, exactly the same as
my last model so will be fitting that this weekend and cleaning out the old
one for use as a spare.
Well chuffed !
