Hi Chicken/list

Nothing piccy worthy today, finished the render on the dragon stove den, so Mrs desp has tape measure in hand and is off down the tile shop,whats the betting she just loves the most spensive at 150/m2 . Rest of the day was spent didling the lectrics and connecting/commisioning the new gasser.
It is great being able to heat the system quickly at last, 24Kw on full blast and it was all hot in about 20 mins, it used to take about 2 hrs to get any 2 zones hot, and if all five happened to be calling....forget it.
So for a weeks work we managed to get the fireplace knocked out and rebuilt, new boiler and some preliminary pipery for the WBS, oh and dust all over the house of course  . Next week round 2

Round 2

Spent the day running pipery from the dragon den up to the loft, why is it when you need to go through the ceiling/floor there is always a joist/noggin/trimmer or some damn big lump of crete in the way, what should have been 4 neat drilled holes turned into a sort of lift shaft .
Also wacked in cylinder vent and feed pipe from the kitchen to the loft, took about 5 minutes, doncha luv Hep2o. So next on the list is the solar loop, and then ............Oh joy is me.......... we'll hit the nightmare of the airing cupboard, then hopefully scaff up and the good peops an Navitron will say come and get yer stuff and this thread will look more like it belongs here.

CU Soon

Hallo all

not much movement at cactusville today, I had to run a whole bunch of errands and meet the sparks at the last job we did to suss out the finals, after sorting out a couple of snags and drinking a brew or four (tea you understand ) it was nearly 3pm, still I checked out that flue supplier you linked me to Ken, and decided to go for it and line the chimbley, Total cost of all the gubbins for a 7 inch system worked out at 360, so not too bad, and the beyond comprehension will have no cause for complaint. Of course the big problem now is I have to tell Jarek to bash a big hole in the chimbley breast he spent two days bricking up and knocking up render for .......hmmm, I know I'll say it was Brandons fault,, yeah thats what i'll do, huh. Jareks a big bloke you know so if you hear a rumble at about half eight tommorow

If I can still type, more later

strange how Brandon is in Wales, Sleepy in Lewis and  StB in Northumberland - Though Jarek might be able to find KenB easily....

Do you really have to close the chimney stack off with a concrete float? I've used a metal plate, cut to exact shape by our local metal bloke. The only difficult bit is sealing the fluepipe against this plate.
The beyond comprehension didn't even look at it.

The metal plate can be fixed from below, so no bashing of great gaping holes in beautifully plastered walls

Hi Klaus

I did try to puzzle out a way of doing something similar, but I have  a square of masonary at the bottom of the throat/gather 3 sides of which are pre stressed lintols. I am a bit nervous of drilling into them, I suppose the liner/flue pipe adapter could be welded to the plate, OTOH knocking out 4 or 5 bricks isn,t too big a deal, and the raft sorts out fixings and seals in one go,     aarrrgghhh

All the best

Hi all

.....well after sweetening him up with 3 cups of v strong black coffee and an extra smoke break, I said Jarekwe need to bash a hole in the  chimbley agin lots of muttering in Polish, something about "curver??" I think I got away with it

Seriously though he's the best worker I have ever seen, he never questions anything, and just gets the job done, when he's on a roll, if you get in the way, you'll get run over

Anyway the flue bits aint here yet, so we got stuck into that airing cupboard, making up manifolds and pump/valve bits, most of the pipe runs in. Hopefully drain down tommorrow and swap over, maybe.

               How are you designing the heating side Des? are you still opting for zoning ?

[desperate]

Hi Chicken

yeah we have six zones including the DHW, and the bathroom which is on with the pump, this part of the layout is not being changed, I first zoned it off like this because the boiler was way too small for cactusville and it happened to be easy to do, we have a riser in that cupboard you see and the garage, so splitting the circuit was the easiest wayto go, and we can heat each bit as needed. It has worked well for  7 years now, so if it aint broke,...

            Hi Des,

  Wouldn't trv's be suffice for each zone, as theres a good few valves to service if anything goes wrong.

Chicken
well trv,s would control each rad, but I wouldn't be able to have differing times for each zone, at the mo, the laundry and the conservatory can come on 24 hrs a day, keeps me Mediteranean plants happy at night. Upstairs and downstairs are on normalish timings and the hot water can come on a 4.30 in the morning if the stat is calling for heat That way I have pretty much independant time and temperature control of zones. However it is a nightmare to reprog after a power cut

When my Mum got new central heating I asked for 2 zones (upstairs and downstairs) and I recon she uses a lot less fuel than she used to. If I was to change it I would put the bathroom on a seperate zone as well, if she gets the bathroom done she can split the DHW zone in 2 and have the zone valves in the airing cupboard which would mean that very little extra plumbing would be required.
So my opinion is:- More zones and more timers are More better init.

what about adding in a extra zone valves and controlling them with wireless stat, that what i plan to do as per daftlad's mums house.

just fitted a worcester bosch 37cdi boiler with a radio frequency programable digital thermostat, works great

Because the downstairs and upstairs CH pipe loops are easily accessible it would be (I think) straighforward for me to split into two CH zones. However what puzzles me is how usefull such as split would actually be for us?

I imagine many houses with 2 zones have lower thermostat in the hall, upper one on the landing; and the stairs lead up from the hall? Doesn't the heat from downstairs simply keep rising up the stair well, the lower zone 'works harder' and simply ends up heating the whole house anyway? Maybe I've missing the point somewhere.
