Excellent John thank you, I've found the sample point on the top right hand side of the boiler, We've tried the tester again, the results are similar to the above although the flue temp is lower and the C02 is up to 11. Doe's this mean much to you ?

Thanks John, I've had a look, we can't see anything obvious regarding sample point for flue gas. I do see the 2 nuts on top of the combustion chamber but we had no intention of going in !! Would I be correct in saying there is a baffle diagram on the underside of this hatch ?

Thanks again for your input. By chance we've got a shot of a Sprint V2 tester from a friend. Now we stuck the probe into the flue terminal and the readings we got are below, the guy we borrowed the tester from knows nowt about oil he deals with gas only so he's not much help ! CO 9...

Hi Boilerman2, Thanks very much for that, you were spot on, we've just checked and there is a green plate (much like a vin plate) It has the nozzle size required (0.55/80), it also states that the flue temp should be below 350 degree. Upon checking other threads here it would seem we...

My son has just bought an old farm house with this boiler fitted. The boiler looks very old although it works away fine, he phoned someone regarding a service/general health check, the engineer said he would need the service/installation manual for setting this up. We've tried looking for...

As title really, Doe's anyone have much experience with any of the above, I did start a thread a few weeks back about the 25c Heat master as my plumber had recommended this instead of unvented. Having done some research through the forum etc there is not much info on the Acv but I notice...

Yep not much in it cost wise at all, I think the ACV ticks all boxes, I'm also going to go with Weather Comp with this install. As you say, the installation cost could well be a lot less. Just out of curiosity, will I require a zone valve for this ? I don't intend zoning parts of the...

I've done a little research on this, seems to be decent kit but the unit is some size. Cost wise, it comes in at around 2.5K for the 25c. I've spoke with another plumber and he advised Unvented with a system boiler. What is the preferred option here, am I right in thinking the heat...

I will have a look at Atmos also. Thanks

The plumber did mention he would run a separate 22mm supply from the main supply to the unit, he checked the water rate with a some kind of cup and said no problems, working cold pressure was near 3 bar from what I recall. Had a quick look at the highflow, 25L/M so that 250 in 10mins.

Anyone got much experience with these. I've recently bought a new property (4bedroom 3bathroom) the plumber that came round has advised and priced to install the above. Currently have an old Potterton with vented HWC. I was thinking along the lines of Highflow 550 or unvented cylinder...

I've just purchased some ground with planning permission to stick up a 3 bedroom kit. The answer to this could be "how log is a piece of string" but here goes, Duration for plumbing and heating works, would 150 man hours likely cover all bases here IE. 1 x Central Heating install (9...

Thanks for the input, I've got someone coming to see the tenant tomorrow about a new boiler thanks to the government.

I've had a service engineer out to service a back boiler in a property I currently let. He said the ventilation to the boiler wasn't suitable and it should be a "Stadium Vent" it currently has a 9" x 4" vent into the floor. His parting note was "the best option would be to pull all out and...

When he tested working pressure at the boiler he had the boiler running on full and he also turned the 4 rings on the hob on. When he tested working pressure at meter, he turned boiler on full but didn't turn the hob on at all.

So only the boiler need to be running on max when checking pressure at meter. Thanks

Quick query here, If testing working pressure at a gas meter should all gas appliances be running at full rate ? IE Combi boiler with Hot tap running and gas hob with 4 rings burning. I had a chat with the fitter today, he tested meter with boiler running full but didn't have the hob...

Magic thanks, Makes sense not to pull it to bits if it's not required then. Cheers

I've got the above boiler and it's due it's first service, the engineer I spoke with about the service said it will just need gas pressures checked and the flue gases checked with a FGA. I had a look through the manual and says burner will need cleaned etc ? Cheers

Good to hear, Think I'll give him a bell in the morning and get him to go ahead with pricing. Thanks for the input. B
