How many kW's of gas can a 1" pipe handle? (ish) :)

I think that will be adequate, but just bear in mind that this will take 30mins to heat back up again and it can run out quickly, especially if you are running the kitchen sink doing the pots then wanting to use the basin. To be safe I would go with the 13kW Redring heater too.... obviously...

Just after some advice please, is there any problems with installing a twin coil cylinder (bottom coil connected to solar panel circ and top coil to the boiler circ.) and also incorporating a hot water return loop. I understand most of the twin coil cylinder shave a secondary return connection...

If you are going to the trouble and expense of having a new high efficency boiler fitted, then why are you trying to put an open flue on it... personally I would be wanting it with a concentric flue, the cost difference would be minimal... maybe cheaper. This will therefore not be effected by...

Its normally other contractors that come along and fill the hole back up.... normally within 5 days or so from experience.... stop worrying, they have obviously been and fixed some fualt on the supply... better them doing that than not doing anything... calm down. :D :D

Personally, I would say, fit the boiler in an outbuilding with underground F&R's to the property. Most houses don't have this advantage so I would say go with option B. You may find the oil boiler could be a bit smelly if it isn't operating correctly or you have a bit of oil spillage etc. +...

Thanks Tony, please accept my apologies about what I wrote.. i must have been in a bad mood that day. Thanks again for your helpful reply.

Replace the 3 port diverter valve.. the exact same thing happened to my heating a few months ago

Some advice please... Is there a maximum length for a pumped hot water circulation loop i.e. would you say a 40m run from the cylinders to the last hot water tap is excessive... ensuring the bronze circulator is sized sufficiently? I presume you can get this length of circuit, and probably...

This is getting amusing now: ALL AGREED INPUT = MORE kW OUTPUT = LESS kW thats why you get say a 90% efficient boiler, if it was the other way round then you may get say a 110% efficient boiler..... thats where heat pumps come into it, but lets no go there eh?? :lol: :lol:

You have only cut out the last part of the sentence... he said: its the output, not the input wich is about 35% more.

No.. its the input that is more, which is why the output is less i.e. 100kW input boiler at 85% efficiency means that it has an output of 85kW (a lesser figure!) :lol:

It is probably a 90 kW 'INPUT' which at say, 60% efficiency could be more like an 'OUTPUT' of 50-60kW Do check and investigate further

Too close... you could try and incorporate a flue diversion kit of some kind... depending on what boiler you were to chose. This would direct the flue gas elsewhere which may help in this situation.

That sound bloody expensive to run to... sounds like the whole system needs an improvement... put in an indirect cylinder and heat it from the new boiler would save ££££'s on your bills. PS 90KW... sure your gas meter is up to it... is it a U6 or U16 size meter??

So does heating a house with drafts and single glazed windows???

Thanks for yor comments, its really working well apparently... kicking out the heat. Could this Turboflex plus be retro fitted into the existing flue at a later date??

Had a Worcester Greenstar Oil Fired boiler fitted to the existing stainless steel flue. Worcester came out and ok'd it, as it is condensing compatible. All working fine. Thanks Guys

You could be right... do the two rads at the front of the house get warmish or hot at all or are they stone cold?? 8)

Just realised this was a very old post but couldn't resist a reply!! :?
