Advise on a NEW indirect unvented hot cylinder

[Lumen]

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!

Hi lumen, what type of boiler do you have or would you consider when installing a new system with an unvented cylinder?

Hi Matchless, we currently have conventional Ideal Classic FF350 heat only boiler.
I hope that helps,

Its a long time ago now , but I used to work for the now Kingspan, they used to be known as “Range cylinders “ .
Their cylinders are very good, in the hundreds I used to go out to fix under warrenty , 99% of the faults were caused by the muppets that installed them .
I wouldn’t hesitate to fit one in my house .

Personally I wouldn't fit mega flo. You're not getting anything extra for the extra money.

All your estimates from g3 qualified people?

Gledhill or joule

OSO all the way for me.
Never ever had a prob & honest impartial pre-sale advice to the the point of non-supply if not thought truly beneficial or performance considered borderline

Vaillant uniSTORE for me as well as Vaillant System boiler. I wouldn’t want to mix the brands though but that’s down to budget and preference.

Where are you based on london

Hi Simon,
Those are exactly my thoughts, I'd usually go for a top of the range, but in this case, it seems that it's not worth 40%-50% more.
Yes, all the plumbers that came and quoted are G3 qualified. I know you need a G3 certificate to work with pressurised systems, so I'd expect them to leave a certificate after install, as otherwise it doesn't pass inspection and will cause issues when it comes to selling the house.

Interesting, not even looked at that brand.
I'm in Hounslow, West London.

 

[Lumen]

Interesting poll results, thank you everyone for contributing!
So nobody here, would even consider Telford
Interesting... Glad I've asked now.

Building control certificate takes 4-6 weeks!

Building control certificate takes 4-6 weeks! Benchmark certificate should be completed on completion

Thanks for heads up Jase. I will ask for benchmark certificate on completion. Do I need to get building control certificate after the job is complete or just before selling the house?

It should arrive around 4-6 weeks after installation. If it doesn't arrive then chase up the plumber.

Yep, Gledhill for me all day long

Hi chaps,
I'm settling in for either the
Joule Cyclone Standard (TCEMVI-0150LFB)
or Gledhill ES (SESINPIN150) or Gledhill Stainless Lite Plus (PLUIN150)
Do you chaps know what's the biggest difference between Gledhill ES and Gledhill Stainless Lite Plus?
Both of these are B rated and second is slight lighter, but there's about 25% £100 difference in price.
What is the price difference due?

 

[ShaunCorbs]

Prob thinner go for the thicker one

 

[Lumen]

Prob thinner go for the thicker one

Shaun, pardon my ignorance, but thicker in terms of wall/insulation thickness or overall diameter?

Hey guys, here’s the final update on the post 3 weeks after instal.

I went for Joule cylinder in the end. The install took one day, but that involve me preparing everything a week before and running the 22mm waste pipe along the plumber installing the cylinder.

Only thing I’m planning changing in this set up is adding an automatic by pass, but that’s for a next bank holiday weekend, I’ve got clockroom to do first.

Building regs certificte came through the post yesterday, so all seems good. Many thanks for all who contributed and advised, I’d get you a beer each if I could
