  1. I'm trying to shut off the hot water supply to repair the kitchen tap. Unfortunately I can't see any isolator valves near the tap, so I'm puzzling over how to shut off hot water for the whole house. I tried to do a bit of research into how our heating & hot water system works, but I may be getting this wrong, and to be honest I'm kind of tempted to just post the question "What the heck do all these pipes do?", but I shall try to be more specific. It's an F&E system with two tanks in the loft and hot water cylinder in the first floor airing cupboard, which looks like this: So according to these instructions I need to close a valve which feeds cold water into the bottom of the cylinder. "This valve should be easily recognisible as a valve with a red, wheel-shaped handle on a pipe that runs from the ceiling of the airing cupboard to the bottom of the cylinder." The valve in the top-right (just above the top shelf) seemed to fit that description, so I tried closing that. Then I noticed the valve in the bottom left could also fit that description, so I've tried closing that too (although I may be misunderstanding the direction of flow there) I notice there's three pipes leading into the bottom of the cylinder. The third one slightly higher on the left is hopefully shut off by the motorised valve (I have the heating and hot water switched off) I then try running the hot tap for a minute or two, but it's showing no signs of stopping. Do I just need to wait longer for pipes to drain out? I tried the same on the 2nd floor bathroom because I thought it might stop flowing quicker there, but ...no sign of stopping.
  2. Hi Folks, Nearing the stage of starting and another question has popped into my head! So we will have a duel fuel rangemaster cooker in our kitchen (electric, gas hob), to which the gas will come from gas cylinders (47kg Propane). Now our cooker is located at the front of the house and the last thing we want is the cylinders outside at the front! What would be involved to get the gas pipe to the back of the house, this would be approximately 12m in distance. Would we have to incorporate a duct into the foundation slab to carry this pipe from the kitchen? If so i would hate to forget and be left with horrible cylinders at the front of the house! ?
  3. Our MBC passive new build has no conventional heating system. We are now embarking on plumbing. We want to make the right choices for a vented copper DHW cylinder needed for up to 4 - 6 people. The hot water will be needed for 2 gravity-fed mixer / pumped showers, 3 bathroom basins, a kitchen sink and a utiIity sink. We think we need 3 immersion- type connections on the cylinder: The energy from the solar PV will preferentially divert electricity into an 'immersun' type element (probably in the bottom of the cylinder?). The main energy source - when the sun isn't shining - is likely to be a conventional off-peak tariff immersion heater (again near the bottom of the cylinder?) And we think we ought to have a back up immersion for occasional use only, positioned near to the top of the cylinder. The two power showers will need to be fed via (2 no. ? twin) impeller pumps from the cylinder - probably (?) with 2 separate connecting points off or close to the top of the cylinder with some means of ensuring no risk of air bubbles into the pump in-feeds. We think we're probably looking at a cylinder in the size range of 200 - 300 litres. Having looked at a number of topics on the forum, we can’t find suggestions that address our specific queries, hence this post. We'd be very grateful for any advice and guidance on selecting the right type & size of cylinder & configuration of connections.
