What central heating/hot water system do I have?

Sponsored Links
Yes I would get it all replaced. Don't waste your money on that heap.

A combi might not be the right choice for your property or needs. so look into whats best
 
Great - thanks for all your help.

I was thinking of going for a Worcester Greenstar 30i System?

Any advice/recommendations?

That's sounds a good choice.... depending on the size of your house you may not need it so big.
Go for new cylinder and controls as well.
If you have the pressure then unvented would be best and lose the tank in the loft

I've turned up the thermostatic valve to 5 and the hot water is ok.
I don't get that. The valve was already at 5 on your earlier pics, and with the phial out it doesn't know the cylinder temperature.
My guess is the cylinder only gets heat when the boiler fires because one of the roomstats is calling. If the weather where you are has cooled off a bit (it has where I live) that might account for the higher HW temperature.

Sorry - it was 4.5 originally and I moved to 5. The pic I sent yesterday must've been after I moved it.

The previous owners mentioned they turn the thermostats right down in the summer. If that's the case then and what you're saying is right surely there'd be no hot water.

Its currently an unvented system (no tank in the loft).
Details about the house
- 3 stories including converted attic
- 1 bathtub
- 3 showers (2 mechanical and 1 electrical)
- 4 toilets
- 5 sinks including kitchen sink
 
Worcester Greenstar 30i System

Personally I wouldn't hang a WB on anyone's wall, I don't think they're worth their inflated price tag and I seem to repair more WB's than any other boiler make but that just me.

I'm also not getting into what's the best boiler debate either I'm afraid, that's a can of worms that seems to get everyone's back up in this forum and no-one can agree.

Seems strange. Do you have a white or blue expansion vessel anywhere (looks similar to the red vessel for the central heating)

Boiler service notes:
Full service carried out on the boiler on 24/02/2021
The rust staining inside the boiler have gotten larger since the last service. The leak appears to be coming from the back of the
heat somewhere (see photos attached).
I advised the new owners to contact Vokera Ireland directly ( 0567755057 ) to replace the heat exchanger and condensate
conveyor.

would be very surprised if it needs a heat exchanger, the flue conveyor will be split very easy job
So you think its just the condensate conveyor then?

When I asked vokera for a quote including the heat exchanger replacement they quoted €400 - So I thought to myself, am I just better off getting a whole new boiler? But I guess if you say its just the flue conveyor this should be a considerably cheaper job.
 
I'm sure ianmcd knows what he's talking about.
After fixing that, I would make quite sure there is a bypass pipe (from somewhere on the pump discharge to the boiler return pipe) and then put a live feed on the terminal which starts the pump and boiler. (make sure it needs 230 volt, get a sparky in if necessary). Then the cylinder should get hot.
If the valve is OK (from the pic perhaps the capillary is cut off, but it's hard to tell) cut a strip out of the foam insulation about 1/3 up from the bottom, and insert the phial touching the cylinder wall. Need to do a bit of patching up!

All being well, you could then rig up a switch for the boiler. Switch on for about an hour each morning, should be enough hot water for the day. You can check how long it takes for the valve to close to adjust the time. Add a timer in future if it seems a good idea.
Your system should last for years.
 
yes will be the conveyor, very common fault, easily changed
Thanks - I'll get that seen to. Hopefully they won't charge €400 (swear stuff is a lot more expensive here than UK).

That is definitely above my skill level. If you're ever in Ireland please call in - can pay you in Guinness.
 
I think what you have been quoted is Vokera fixed price repair, so will be the same cost regardless, you would be cheaper getting an Independent to swap the conveyor they are not expensive and an easy job
 
Email from engineer who carried out the service:
Hi Gavin,
It’s not just the conveyor that might need to be replaced. I would advise getting the heat exchanger replaced as well due to the corrosion damage. From my experience with that model, your much better off getting Vokera Ireland to carry out the repairs.
My quotation would be over €1000.00
