Get a mate to help you move them.

Find the manual (available from their website) and have a good read before the installation date.

Just re-reading, are you oftec qualified? Sorry for the blunt question, but I don't want to jump to conclusions!

 

[ecowarm]

I would agree with kimbo on that one!

 

[Bunker]

Deffo the manual.

Also a think about the condensate run, the electrics, plan the day to ensure they have hot water in the evening.

Finally, loads of bits and pieces required. A check in the manual for all the tappings, etc.

Good luck!!

cheers guys i take it they dont supply the male irons ect ??/ ive sorted filtrs fire valves ect already

Trying to remember now. 22mm ef st conns for the flow and return, 15mm ef st conn for cold water, 22mm ef st conn and 22 x 15mm ef red for ho****er and 15mm ef st conn for prv. 10mm Iso valve supplied for oil line. Overflow pipe for any internal condensate run. Don't quote me but you'll need two plugs as well one for top I think is 3/4" (but may be 1") and an 1/2" for the bottom. The heatslave now comes with drain offs on the boiler and heat store. Tighten em before filling tho.

They don't - hence why I mentioned it. You'll also need a couple of blanks, probably. Remember silly things like glue for the condensate run, inhibitor, possibly a spare trv (if you've one in the garage). I normally do these with a mate and it usually takes both of us one day with me returning the next day to finish off (and correct all his mistakes!!)

It might drive you mad, but you'll have a great glow afterwards when you turn it one and finish tidying up. A real sense of achievement and satisfaction.

and don't forget a sack barrow or skateboard for moving it around.

Every oily should have a skateboard in the back of the van. Less room than a sack barrow and will hold a Stanley cooker.

 

[lame plumber]

3 lengths of broom handle/steel rod takes up even less room

 

[SimonG]

Easier to steer on the skateboard

I have a few short lengths of 1/2" steel for the really big uns.

Or arrange delivery for about 12pm then you can get the chap to help you take the old one out and put the new one in place. You should be drained and disconnected by 12'ish.

Normally on my piping by then

Boiler delivered for 8.30 at the latest. Fired up by 3.30 and away before 5. But that's two of us.

In my dreams! It just don't seem to work like that round these parts!

Big requests:

Make sure you put a filter in the line but somewhere its accessible and room underneath for the service engineer to take apart (not that anyone other than me does blah blah..;-) )
Make sure the fire valve is the right way round and the right way up
Make sure you fit an isolator in the oil line if there isnt one.
PLEASE make sure you drill one hole for the fire valve phial to go through and separate ones for the condensate and PRV - 3 in all. So many fitters stick the fire valve phial through the condensate hole, then stick the condensate through it - a royal pain when we have to change the FV.
Make sure you arrange for it to be commissioned by an OFTEC commissioner - its YOUR responsibility to arrange that
