My Ravenheat boiler has died, the pilot wont light up I have had the gas valve, pilot assembly, thermocouple and electrode replaced all without any joy.

It has probably not been the most efficient boiler but it has served me well for the past 13+ years. I have now decided to replace it with a Vaillant ectoec 837.

In preparation for the new boiler I would like to clean the existing system. I have flushed it completely twice and today added X400 Inhibitor cleaner.
I have set a schedule to fire up the system every day for an hour,

Obviously because of the issues with the boiler I am not expecting any heat output however after turning it on today I get the feeling the boiler is not even switching on to circulate the water because the burner is not lighting up, is there a way I can get this to work without having to spend any money on the boiler? or dare I ask a way to bypass it?

Thanks

Hi again.

Simple to just wire a plug on the end of the pump.

Don't know if I like your choice of boiler,

Have a look at the Broag Avanta range, a much better boiler in the same price range.

Hello again and many thanks for all the help

Any chance you would be able to send some additional info on wiring up the pump?

As for boiler choice, I have been quite traditional and looked a the two favorites, Bosch and the Vaillants, I had decided on the Ecotec exclusive but have been advised that pump failure is a bit of a 'feature' on these models.

Never heard of the Broag Avanta range, will google it later. Are they well known in the UK from a servicing/parts perspective?

I chose the Vaillant mainly because of user feedback from the forums, people working in the trade and from friemds that have hed them installed.

Which ravenheat is it.

Vaillant is without doubt the market leader in poor service.

Dave has gone over to Avanta, since I mentioned them and he raves about them now.

He will have more to say later, when he logs on.

This is for the RSF, but the idea will be the same.

If you see the L,N &E wires into the pump, all you need to do is make the boiler safe and wire an extension lead into those terminals.

Hi there,

the boiler is a RSF 820/20, although by no means an electrical expert I can see the parts listed on it resemble the hardware on the unit. to make it safe I intend to switch of the gas supply and am also considering disconnecting the pump from the main control board. Does this sound about right?

As for the choice of Vaillant, TBH I did not spend much time looking at other makes, had a look at Bosch and Visemann and Vaillant seem to come out on top for me. Plus our local corner shop DIY emporium can do me a good deal on this with a fancy weather compensator programmer and since I am a techno snob it appeals to me whether its actually used positively remains to be seen!

Thanks again

yes just disconnect the pump wire out of the board and put a plug on it.

im not sure that the X400 will do very much to clean the system without any heat

what is it that you dont like about worcester bosch ?

Vaillant are still good boilers, but are now way over priced and after sales service is a joke

I just priced up a job yesterday with a Vaillant and a Broag, Broag came out £300 cheaper with a full 5 year warranty as well

Personally I would never fit a WB as long as I have a hole in me arris

whats put you off WB Dave

I only fit WB unless the client insists on another brand, ive never had any problems with them

I too stopped fitting vaillants about five years ago because of the companys terrible support back up, and when on several occasions i had to phone thier technical dept, the guys behind the phone always refused me to give me thier name

I think they are poorly made, awkward to install, even more awkward to commission and service.

I feel they have lived too long by tagging onto the Bosch name.

They only get good sales figures by all the freebies they endlessly give away with them.

Apart from a basic service I don't usually go out to one, I always tell the customer to call WB in.

So all in all I can't stand them

Apologies if I have started another Vaillant Vs WB debate, I've read numerous threads on the topic on many websites and should have known better...

I don't think it is a debate as on other websites, I feel we are more mature than that on this one

Some such as Rio, will always swear by WB, others like me do not like them.

As long as everyone is happy with what they fit, then it does not really matter
