Ideal mexico upgrade proving tricky

[king of pipes]

Got a upgrade to do on one of these the boiler is in the utility room fitted totally illegally as blanced flue is only 500mm away from a opening door into the house now the fun bit it has gravity hotwater pumped heating pump is next to the boiler , cylinder is upstairs has no control at all and no insulation only a red jacket , vent and cold feed connect into the gravity primaries , planning on fitting a worcester greenstar classic 30CDI wall mounted with vertical flue , new vented cylinder , dont want to go sealed as has 30 year old pipework in sand and cement screed downstairs but need to do a s plan somehow cold feed vent and wiring proving the awkward bit any ideas guys or alot of chipboard is going to have to come up or i have to go sealed but really is a last resort cheers kop

Can you get into the heating pipes by the cylinder?

 

[king of pipes]

Dont think so 1" gravity primaries shaun not sure how upstairs rads are fed if i am honest must rise somewhere whats your thinking bud .

 

[ShaunCorbs]

Was thinking of using the grav as your main flow and return

Then you could get a normal heat only boiler and put your pump vent and fill and port valves in the airing cupboard if you could get into the heating somehow

Maybe bud will have to have another look will need wiring between the boiler and airing cupboard though . cheers kop

Or go with a wiser set up (wireless)

If i went system boiler it would be better i can keep all the controls at the boiler and wouldnt have to worry about vent and cold feed but not without risk got to upgrade some rads will give me some idea what condition its in cheers kop

But then you would have to seal it which is a down side

That’s what I was thinking.

Seperate system with a plate or header no need to pressurise then

 

[king of pipes]

Not got the room for that bud , shauns suggestion looks favourite wiring is the issue may be able to find a route if not its gonna be sealed and pray cheers kop

Worcester Greenstar System CDi will operate in a sealed not pressurised scenario as they do not command a minimum operating pressure. Seal off the vent pipe with a manual vent, fit a non return into the cold feed and a decent isolating valve. Loop the returns. Have fitted this in the past to overcome exactly this type of thing.

Won't that affect the manufacturers warranty ? and I still need control over the cylinder stat looking at the sundial RF2 packs not 100per cent which pack I need wired programmer wireless cylinder stat and room stat thanks for the advice . Cheers kop

 

[mfgs]

Either move the boiler to the airing cupboard or loft if possible or fit a system boiler. On old systems when sealed I fit an adjustable pressure reducing valve before the filling loop, turn it right down and also add an extra expansion vessel. Vessel charge needs to be adjusted for lower pressure set up.

Where do you buy your plate heat exchangers town ? Cheers kop

 

[Vee]

Having it sealed unpressurised is within the manufacturers recommended installation practices and does not affect warranty. Use a wireless thermostat as Danfos CET2000B for the hot water.

Havnt bought one in years , I just want to put combis in with the minimum of fuss lol #gettingtoold lol

 

[king of pipes]

Me to bud sod it going to to quote to put a system boiler in and run it at 1 bar cold pressure and keep all the controls at the boiler sundial RF3 pack for stats if it fails i will deal with it . cheers kop

 

[king of pipes]

Customer went with it so fingers crossed thanks for all your input guys . cheers kop

 

[king of pipes]

I actually like the install, for what you had looks tidy and neat. Most important customers is well happy and that’s all it counts. Did you have to re pipe a lot?
