megaflo hot water and heating system with tanks in the loft
Hi All and thanks for looking,
I'm having the loft converted in our semi-detached in Guildford, Surrey. It'll end up being the largest room in the house. I'm putting an en suite shower room up there too, directly above the current bathroom - that also houses the hot water tank. I've been thinking of changing our current batheroom in any case, and the water system with it, and the loft conversion company mentioned installing a megaflo system with direct pressure from the mains and storage tanks concealed around the eaves of the loft. Has anyone on this board: a) Ever done this successfully b) Any knowledge of the flow rate required - my in-laws have direct mains pressure feeds and their flow rate is the same as mine (around 18 lpm) c) Any idea of the cost of altering the mains to increase the flow d) Any recommendations for manufacturer of megaflo systems cheers Gaz |

For some reason this group seems to have very emotive responses to the discussion of pretty mundane hot-water and heating systems, with vehement and implacable postions being adopted. This thread is likely to collapse imminently into a slanging match. Just thank god you didn't suggest installing a combi. |

He is killfiled by most regulars unless they feel like engaging in amusing argument that leads bowehgere. Drivel knows a lot of things. Sadly none of them are factual, and most come out of glossy catalogues. The consensus is that he is mentally unstable, and has a fixation about plumbing, and the nurses give him access to a computer and plumbing catalogues to keep him quiet, when the medication necessary to remove the conviction that he is Bob the Builder cut in. |

ALL unvented cylinders can explode if all safety aspects fail. That was obvious. |

wrote this:- I have had a look at the heatweb link you posted but cannot find any reference to the Megaflow brand exploding. I have no idea which brand was involved, but ISTR it was an "unvented" system which exploded in the case outlined in http://news.bbc.co.uk/1/hi/england/somerset/6500565.stm though I would not argue against such systems from this and other cases. Provided they are looked after properly such systems are acceptably safe, though I wouldn't want one where large volumes of water could pour on anyone below. Vented systems can also explode, or indeed collapse, though they are more forgiving and they are less likely to cause as much damage if it does happen. As for thermal stores the two on the right in the photograph on http://www.mcdonald-engineers.com/pr.../thermflow.htm have header tanks built into the top of the unit. This would be the only header tank you would need and it would feed the heating as well as the thermal store. As long as this is above the highest radiator there will be no problem. Cold and hot water would be at mains pressure, so your en suite shower would work fine. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |
