Advise on a NEW indirect unvented hot cylinder

[ShaunCorbs]

How did he manage to get Bulding Regulations Notification certificate? As I have it in the post with his company name on it.

Guess he lied on it

Hmmmm I’d still be dubious. The valves thing is unventeds 101. Does someone at his company hold the qualification but not him??

Hey guys!

Came here to get advice about building a new shower and changing my current F&E heating system to accommodate this. There have been some great advise (I am glad to be part of this forum and this great community) majority said to go for an unvented hot cylinder.

I've had few plumbers looking at the job and quoting. Quotes range from £1,500-£3,000 all in all (Removing the current F&E water tanks and getting 200L unvented cylinder in West London)
1) Is this reasonable?

All 3 plumbers quoted with a Megaflo cylinder. Which I know is a market leader, but it costs 40%-50% than some cylinders and I'm not sold by.

I have been doing some research and ended up with
Kingspan Flomaster (FN150ERP)
Kingspan Ultrasteel (AUI150) and
Telford Tempest (TSMI150)

I know Telford have 30 years warranty (2 years on parts) and is made of high grade of stainless steel
Kingspan 10/25 and has 'Duplex' stainless steel

I know there are a lot of professionals on this forum.

2) What are you experiences with these cylinders? Would you guys recommend either or something completely different?

We are planning to stay in the property for about 10 years and move else where after the retirement.

Thank you for any advice in advance!

You say remove the current F/E tank, but why do that if your boiler setup is OK? You could just swap your HW cylinder for unvented and leave the primary circuit as is.

Ouch someone’s not G3

Aversion to pipe bender was also a give away.

Bit late to the party but....

Apart from personal preference, all manufacturers give 20/25 years on a vessel and 1 year on components.

Surely after that, the only thing important would be the r value (insulation)?

So, if 2 cylinders are the same price and with the same warranties, the only thing that would set them apart from each other, would be how long itjt keeps the water warm for?
