Viessmann Vitodens 200-W

[billy bob]

Viessmann have been in the UK for many years already, I doubt that they would ever leave the UK

What do you think CORGI provide during this six year period?

I can not see those people at Basingstoke offering anything in the way of cover for the appliance.

As I understand it, CORGI only guarantee that the installer fits the appliance to comply with the Gas Regs.

I can't see where the 40% figure is coming from, in comparing a condenser boiler with and without WC. There really is a lot of Betty Swallocks on this forum at times.

This guy can't and neither can Viessmann it seems.

Some people say their Vauxhall Astra 1.6s are capable of 150mph after being fitted with a 3" Halfords exhaust but I don't believe them either.

I would just like to clarify one thing.

When I said I save 4% gas over non-weather comp. This isn't a strict like for like comparison as the Viessmann controls allow you to do things that a bog standard controller won't.

Thus the weather comp improves efficiency a lot. but the controls also help a great deal as well.

The 300 is to be discontinued in the UK. Your baby 35kW and all other sub 49kW were dropped in Sept 2007, 49 and 66kW will be dropped in 2008, date to be confirmed.

UK will not get 300 series at all after the 49kW and 66kW have been dropped, W designation or otherwise. That is a real shame because the 300 series 49kW> is the bees knees and the 200 is considered to be the cheaper option in Germany. UK marketing think there is not a good market for 300 over here.

Vitodens 100 ali version was not marketed in the UK.

Perhaps you don't have contacts at director level in the company?

Just keep us all amused about your single installation, I'm listening and learning all the time, what do we know? We only fitted about 100 of them (including Vitocrossal commercials).

In previous posts you made a very poor (and public) job of trying to convince some of the better qualified heating engineers on this forum that you were a degree holding hydraulic engineer. Are you going to shoot yourself in the foot again here?

 

[sanj.varah]

I still stand by everything I said. I got fed up of people not bothering to listen so i gave up. Heating engineers shouldn't even be allowed to call themselves that unless they are chartered. The term engineer is protected around the world to varying degrees but the politicians in the UK have let the term be used by any tom dick and harry who can read and use a screwdriver.

no i don't have contacts at director level.

You actually stated that the Vitodens 100 never came with aluminium exchanger. You didn't say anything about marketing in the UK.

If you say the w300 isn't coming and this is actually true, then i'd tell the OP to buy the W200

According to the Corgi website, the 6 year warranty covers the homeowner if the installer can't fix it. I would like to read the small print and see what it covers, and more importantly, what it doesn't cover. Here's the link:

What kind of things can the controller do that a normal one can't? Do you run your boiler 24 hours?

Thanks.

in no particular order or preference, but it does a lot more than this:

Reduced room temperature mode.
Heating slope alteration, changing the gradient.
Heating slope movement, so changing the temperature intercept.
Intelligent start - so it heats up to temperature when you want to.
Fully modulating pump
Change delta T for heating a cylinder - doesn't apply to you.
Heating logic
Frost protection
Vitocom set - can phone up the boiler to turn the heating on
Zone control. one for upstairs one for downstairs hooked up to individual temp controls.
4 on-off periods per day
burner hours clocked on

it does a lot more than that. but thats only the stuff off the top of my head.

I don't run the boiler 24 hours. I run it for 6 hours on full wack. the other 18 hours its on reduced temperature. My gas bill is £45 through winter. less than half of the previous halstead balmoral boiler (in terms of gas units).

As I understand it CORGI only cover the gas related work, this does not cover the boiler in the event of a break down.

I did consider offering this cover to my customers but quickly came to the conclusion that it was simply a waste of my time and of the customer’s money.

If an installer can not install a gas appliance after complying with all the stuff CORGI expect us to comply with, and that CORGI have us re-doing every five years, and at considerable cost, that you the customer pay for, then perhaps CORGI could be considered to be a Private Monopoly Company that takes Millions of pounds from the publics purse, every year, with little real effect on the gas safety of you the public.

I suggest you contact CORGI and ask for a copy of the small print.

I suggest you write and send it recorded delivery.

I say this because one of the members of the Association of Registered Gas Installers sent a letter to Mr Ian Powney who is head of CORGI and did not even receive an acknowledgement of his letter some three months after it was sent.

Indeed the Association had to ask the Health and Safety Executive to intervene and bring the headman of CORGI (a private monopoly company) to task.

My gas bill is £45 through winter. less than half of the previous halstead balmoral boiler (in terms of gas units).

£45 through winter? So way under £100 a year!

Are you serious? Most people use more gas than that to heat their hot water alone.

If your old boiler used £90 per winter, and your boiler installation cost £2000, you are saving around £50 a year. In 40 years time your system would have recovered its cost........

Running a 35kW boiler 'flat out ' for 6 hours a day does not equate to £45 for the whole winter. Please explain yourself?

I don't run the boiler 24 hours. I run it for 6 hours on full wack. the other 18 hours its on reduced temperature. My gas bill is £45 through winter. less than half of the previous halstead balmoral boiler (in terms of gas units).

For the other 18 hours, is your boiler using gas to keep it as the reduced temp?

I worked out my gas bill, and for the last 2 years i have paid approx £510 each year. My electricity bill is about £300 per year. They're both with british gas with dual fuel discount. I recently looked on uswitch.com and if i switch to another provider, i'd save £30 a year. I'm waiting for the other energy providers to increase prices before i look to see if I can save money by switching.

I'd love to have a gas bill of £45 through winter!

Do you mean £450 ?.

I don't think there's such a thing as a Corgi backed guarantee. I'd check that very carefully if I were you.

As for claims of 40% savings with weather compensation, that is complete cobblers. Just consider a modern condensing boiler with normal controls - room stat, TRVs, etc. Let's say the annual gas bill is £1,000. A 40% saving on this would mean an annual gas bill of just £600 without any reduction in comfort.

It would follow that £400 worth of gas is currently being wasted. How so? Doing what? Is the house heated to 27°C instead of 21°C? Of course not. Any overheating is unlikely to be more than around 1°C so well under 10% of heating bill. Perhaps the heating is coming on earlier than necessary at times, but even if we allow an average excess heating period of say 15mins per 8 hour heating day that would only equate to around a 3% saving.

Sanj seems to be confused about pipe threads. DN 20mm is the same thread as ¾" BSP and R1 is the same as 1" BSP. Male threads are normally tapered (unless they are union or compression threads) and female threads are parallel.
