"Goin 4 D Big 1 Hughie" - Boiler

Have not researched combis.

Do they need good mains pressure?

Our mains fluctuates during the day. We have a mainswater electric shower which does not work sometimes cos pressure is to low.

Well reasonable rather than good.

In which case no combi.

I urge you to avoid trying to install the new boiler in the fireplace. The gas supply will likely need upgrading. The fireplace is likely in a living room which you don't really want a boiler in. So really the only pros are the flow and return pipes already there. Finally the fireplace may be more useful in other ways.

In that case, a combi ain't going to work - because you do need good mains pressure or - at any rate - good flow.

Measure the flow at your kitchen tap (or the tap nearest to the rising main), using a calibrated bucket and stopwatch. Perceived wisdom seems to suggest that you need a consistent flow rate of 20-odd litres per minute - about *twice* what I get!

If you are in southern Ireland, I belive combi's are banned. is that so? If so go for a either, if available in Ireland: Worcster-Bosch Greenstar, Glow Worm condenser. Ideal ICOS. The Quantum boiler has an oulet in Ireland, and a very good boiler too.

I bet you believe in Santa Klaus too

No, they are not

Wasn't going to put boiler in fire place.

Thinking of turning it into an aquarium. "NO, YOU ARE NOT"

At present, fire front is rarely turned on, but there is something primeval and comforting about an open fire when the rain is pelting down.

I saw a trendy electric fire as big as a wide screen tv, ?1500. The security guard, Russian, was not impressed when I asked him how do I change the channel on it.

Anyway back to the boiler; our living room is large, certainly by today's standards, about 10' x 18'. One end has a walk in closet under the stairs, used for nothing at the moment.

Kitchen is quite small, I may not be allowed to site it there; W.S. and all that.

I am aware that the gas feed will need upgrading. At present it enters as

Will be getting a man in to do this. Is there a scale of charges for such work? Does it relate to length of pipe run?

Ok. I now have a new battery for my digital multimeter.

Got thermal paste for the boiler thermostat suppository thingy.

Took temp at suppository with DMM. Goes to 82 deg C before burner cuts out.

Tested flow at site where overheat thermostat is, 77 deg C.

Have drained system and added Fernox cleaner. Running now.

SNIP

Where is its inlet, England?

Don't know about combis being banned here. We have banned smoking in all workplaces though.

It could be that the pressure fluctuates so much that they are not used here.

We watched as the infrastructure crumled in the UK and said, "If it is good enough for the Brits, it is good enough for us Paddys", so we let ours crumble too!!!

In southerm Ireland not that long ago, certainly unvented systems were not allowed, so I assumed all mains presure systems were taboo.

I saw sealed systems being installed here in the early seventies.

Francis

Is there such a thing as a longwave IR transparent projector screen? Projector recessed into ceiling, pointed at 'fireplace', which has electric radiant heater behind. Plus, you can change it for a picture of fish.

Running with Fernox cleanser; flow now up to 82 deg C, return 70 deg C.

Looks like we will get at least another year out of BBU.

Francis

Wife impressed with your suggestion.

I sealed system is very different to a mains pressure water system.

We should do the same, and in pubs and restaurants too.

You are near the mark.

Mains pressure electric showers are permitted.

Francis

They are workplaces.....

To email, substitute .nospam with .gl

Is that the German version of Santa?

;-)

Cheers Dan.

An astute observation, 10/10.
