megaflo

I have a Megaflo cylinder which is probably 20-25 yrs old. I recharge the air gap around every 6 months. All my taps and showers are direct-fed mixers. Thought I might have a problem when hot water from cylinder (pipes there are both hot) is coming out of mixer taps either cool, warm, sometimes...

Hi all, I have got a new Vaillant EcoTec 418 installed recently and noticed that the set hot water temperature is being ignored, instead it gets generated by flow temperature. Also diagnostics menu says that DHW hours are 0. Could this be a result of an incorrect wiring? I'd like to set DHW...

Hi, I am planning on going away in December for a week, and I was thinking of shutter the main water to avoid any surprises when I come back. I live in the UK, in a flat, on the top floor. I have a Megaflo Unvented Cylinder. Is it okay to close the main water for the week I am away? I have no...

Hello, we've Recently moved into a new house which has a modern looking unvented Worcester boiler with a megalo tank. Water pressure in the property is pretty disappointing and flow from both hot and cold taps is no where near our previous house. Doing a bit of spring cleaning and bled all the...

We are considering a loft conversion which may require removal of the cold water tank. However I've read that water pressure should be at least 10 litres per minute for something like a Megaflo and having measured ours a few times, it's only about 6 or 7 litres a minute. Are there any...

Hello We have a Megaflo Eco Plus 300i installed almost 2 years ago and two of the ports (not sure if that's the right way) were left unused and they are dripping water. I am not sure if this is an installation fault or a defect with the cylinder. Below are two images of the leak: I'm not...

Hey all. I've just moved into a new flat with economy 7 so we have night storage heaters and a night heating water cylinder. It's 145L, but we only get half, maybe not even that before the water is freezing. The whole tank seems to be heated in the morning as it feels slightly warm on the...

Wondering if anyone can help. We live in a "new build" house that is c20 years old with a megaflo system as old as the house! In the last year or so it seems to be losing pressure quite a lot The megaflo is on the middle floor and when I run a shower on the middle floor the hot water...

I’m going to be replacing 2 towel radiators like for like and have an ideal Icos HE12 condensing boiler with a megaflo cylinder and tank in loft. I’m aware of what I need to do to change radiators but don’t know how to replace the water that will be lost from the 2 old towel radiators as not...

Hi, I’m planning on replacing a towel radiator (like for like size) and had a few questions I’m hoping someone could help me out with. I plan to isolate the rad at the valves at the base of the rad, drain it into a bucket (using the bleed valve to release all the water), install and connect...

Good evening all, I’m a drainage engineer with a plumbing background. My property is an old 1930’s, has an indirect vented cyclinder, f+e in loft and also water tank storage in loft. Would like to replace the vented with an unvented. Same location as existing, really good mains pressure on 15mm...

Hi there - newbie here looking for some help. I am not gas safe registered, and not looking to do this on a DIY basis, but I need to know what to tell an engineer when they visit. The boiler is on a Corgi service plan/warranty (which I will discontinue soon). Last summer the property had a...

Hi everyone, I’ve been having an issue with my megaflo direct unvented cylinder, When I turn the cylinder on either boost or off peak, the water leaks though the tundish and keeps going. I’ve followed the instructions and repressurised the megaflo but have had the same issue. I thought this...

I need some help! I have recently had a small extension to our 3 bed semi and with the work they have moved our boiler from the kitchen to the loft and as the water pressure upstairs was too low have installed a megaflop as well. I connected our smart metre earlier in the week and we are...

Hello all, I'm thinking of buying either Tado, Hive or Nest for my house. I live in a relatively new build 3 story townhouse in the UK with the Danfoss TP9000 thermostat / hot water programmer on the ground floor next to my Ideal Logic 15 boiler, a Danfoss TS2 sensor in the living room. Then...

We have a Megaflo D70. Should it be able to keep up with the use of 1 shower continuously? We seems to run out of water after a 10 minute shower at the moment. I don’t think there is another boiler in the system - should there be? ... the property has electricity only.

Hi all. We are having trouble with water pressure from our unvented hot water cylinder tank (a.k.a megaflo/megaflow). Over time, the pressure has reduced so much that we can't get any decent flow rate from the taps in the loft. Ground floor and first floor are very powerful as you can see on the...
