A brief explanation between a vented (usually blue, green or yellow) and an unvented hot water cylinder (usually white). www.upsherheat... 01256 760617 info@upsherheating.co.uk
I had the Unvented fitted a couple of years ago. Best thing ever. Great pressure all the house. The water stay warm for days. Perfect. Great explanation too. Cheers pal.
You should create a central bank for your family release a currency and run an economy for your family. Track water usage with a sensor and heat usage and give out bills. Pretty soon she will realize her water heat and internet bill is cutting on her lifestyle so she will start saving.
Joe, she's left home now. When we visit her in the winter we have to sit under blankets. I fitted a temperature display on the hot water system. When it failed she went nuts until I fixed it. I think its called 'growing up'@@joeroganpodfantasy42
Hi. Thanks for explaining vented and invented systems. Just wondering if I put an unvented unit in and get rid of my cold water tank, how do I get the cold water in my shower/bath?
You should've made the unvented cylinder more rectangle 😉. Wheres you're d1 and d2 pipework Where is the exanshion vessel. 😉 mah fair play just a basic understanding of em.
Hi so my system I have a F&E tank in loft that feeds the central heating system and a hit water cylinder there is a white coloured expansion vessel guessing that's for heating side do what system do I have all the house on my estate have same as me they are 10 years old.
This is the arrangement we have in the UK with multiple safety valves. Safety valves are not featured in this video as it's aimed at people getting a basic understanding between the two systems
Hello Paul, the basis of this video was for simplicity. If I was doing a video targeted at fellow heating professionals, you would have a case. We have not included the expansion vessel, control inlet valve, D1/D2 pipework, zone valves, T&P valve amongst other requirements because as professionals this would be our job to carry out.
Hi I have a unvented hot water cylinder in my flat.. When attempting to change my bar mixer shower, hot water continues to pour out of the hot side. I have turned the stopcock off and water stops pouring out of the cold side but not hot side. Do you know how to turn the water supply from the unvented water cylinder off?
From what I recall.. I attempted to turn the valve anti-clockwise for the hot water pipe that leads to the bar mixer.. due to the age of the valve and corrosion it began to squirt water out... so I was forced to turn the whole supply off from cock stop. I was without water for 3/4 days awaiting for an engineer to come out and replace the valve and bar mixer. In regards to the bar mixer he used PTF tape to prevent water from leaking. I later replaced the valves from the cyclinder to industrial ones with a ball and lever so that they never corrode.@@marcusdavidsmith3047
Really helpful thanks Scott. We have a heatrae megaflow tank. I currently have a Trevi boost shower which I want to replace. Will I need a pump or what type of shower do I need to look for?
demonskier1 if there was no expansion pipe, then hot water has more chance of mixing with the already cold water. Making the chances of bacteria, such as legionella to form. You don’t want the hot water to go into the tank, so the pipe must be raised to allow for this. The expansion pipe is required to conform with water regulations. Hope this helps
