    TMVs and direct DHW cylinder heating

    Hi again The next stage of the heatbank project will be the selection of a new boiler. However I'm having issues speccing up the system and so far my trusted plumber (CORGI installer for 10 years, will be fitting/comissioning the system and has his unvented ticket ;) ) and my dad's cousin...

    DIY Heat Bank Part Deux

    LOL, it's a fair cop guvnor. Kinda like hooking up my old mini to the Ferrarri F1 pit garage setup. I think the contrast is why it appeals to me lol Plus it gives me a way to start testing the development DIY (suprise suprise) home automation setup I'm working on. I can't use that phone...

    DIY Heat Bank Part Deux

    LOL I have three handsfree setups - bluetooth headset, bluetooth to the GPS and an old fashioned wired setup. Are any of them ever plugged in when someone calls? Are they bugger. I still have to switch to speakerphone mode and shout at the blasted thing :lol: I have considered hooking the...

    DIY Heat Bank Part Deux

    I have the same system as (I think) you Gravity mfeed to the indirect cylinder coil with a pump running the heating I don't think there's a problem with the system as such. It's just a conflict of how I'm using it at the moment with how it was intended to be used I work away during the...

    Sealing compound for threaded connectors

    I'm not sure if this is the right way but I've had the same issues with my own DIY plumbing. I have used LS-X on the threads as sealer and have not had a single leak from a copper to iron fitting yet

    Ravenheat - Various symptoms

    I don't think he paid peanuts but neither was it expensive. If memory serves it was around 1800 , about middle of the field. I think he just got a wrongun. As kevplumb would say, something et the front lawn grass :D :D I'll probably just remind my mate of the idiocy of leaving the system...

    Hot water cylinder questions and options

    DIT Thermal Store There's some good info in there from a few sources. I have ended up building mine using the components mentioned :D My experience so far has been good with a but.... The Store side is excellent. I have mains pressure hot water for fairly minimal outlay. All good The but...

    Ravenheat - Various symptoms

    Ooooh, that's a new one on me too. Still, as an ex landlord I can see where you're coming from and giving it some thought I'm certain you'd be correct on that. A tennant is a tennant regardless of whether the landlord is onsite or not However, he is a mate so I can't really force him to get a...

    Ravenheat - Various symptoms

    The guy I lodge with oop in the smoke had a new Ravenheat and indeed a complete new heating system fitted about 18 months ago. So while it's undoubtedly a proverbial brown smelly thing it's still quite a fresh one :D I have no idea what specific model it is, there's no obvious plate on it...

    another of my project questions

    Could you roll it? Whip the blade out of a pipe cutter then use the wheels to just shrink the tube down as though you were cutting it? Only a thought

    shower pump switching

    Er, I'm not a pro lectrician or plumber but how is fitting a switch into the pump power circuit going to cause any problems?? Surely the pump will still use it's internal pressure drop switch to control the motor. No flow = power off. All you do is add a way of turning off the power to the...

    DIY Heat Bank Part Deux

    The open vent thing was just plain dumb on my part. Of course, hindsight gives you 20/20 vision about such things :lol: Fortunately the feed pipe is connected to the end of the pipe heading towards the camera from the pump so it's still the high point of the system. Caught a bit of a lucky...

    DIY Heat Bank Part Deux

    Ah, well, you see :D I hedged my bets. The galv pipe is the hot water piping. Originally the cylinder was directly connected to that. Whilst I had every faith in the system I wanted to make sure that if everything went pear shaped I could etill use the old setup So the silver thing is...

    DIY Heat Bank Part Deux

    Well here goes, Nomex suit donned. At least I know I have plenty of mains pressure hot water to put the flames out :lol: I made one rookie error (that I know of :D :D ). The 15mm plastic is the vent to the header tank. Naturally (I can see it now :) ) this sucks air when the pump...

    DIY Heat Bank Part Deux

    Hello Gentlefolk, An update I started work on this yesterday and am pleased to announce that as of right now IT'S ALIVE :D :D. I'd also like to breifly swear at whoever invented galvanised imperial pipework :lol: Many thanks to all them as contributed advice...... I've ended up...

    DIY Heat Bank Part Deux

    Doh! Cheers for that Bigburn, I can see I've been a bit of a tw@ here. I have confused the switching of the plate exchanger pump with the switching of the boiler circuit pump. I was imagining that every time you turn on a hot tap the boiler circuit is going to fire but that's not going to...

    DIY Heat Bank Part Deux

    I have an indirect cylinder. I now know that I can convert this to direct heating with a couple of Surrey type flanges in the existing feed and takeoff points in the cylinder. My question is this. If I go down that route do I run the risk that water being fed to the top of the cylinder from the...

    DIY Heat Bank Part Deux

    Sadly this is the main thing that's going to kill it off. The guy who normally did the annual Landlord cert also used to service it at the same time. However, he's now not alowed to do the service due to aspestos being present and I can't say I blame him for that I don't mind messing with...

    DIY Heat Bank Part Deux

    LOL The darn thing is probably working just as well today as it was then too In the 10 years I have owned the house (as a rental property until this year) it has never once had any issues other than eating 2 thermocouples. If it wasn't half the size of the kitchen with a bigger gas habit...

    DIY Heat Bank Part Deux

    Will do Forgot to mention, assuming I go ahead (getting more and more keen by the minute to do so, cost permitting) I'll start off using the existing storage tanks as F&E for the cylinder. Again, easy to reverse in the event of unforseen performance issues If all goes well then I'll...
