Had a hot system fitted nov'11. Used everyday till may '12, then use for conny roof/fascia jobs through the summer

Started using everyday again over the last two weeks and now the burner had packed up. Spoke to Andrew and a service kit will cost me £400 max.

Question is, how long should the burner last for? Using a pf controller on 50-does that affect the rate the burner works at?

Excellent heater, but gutted after forking out 3.5k less than 18 months ago and now I've got to she'll out more to maintain.

Did your diagnostic light flash a code to say there is a problem with the burner?Also If you have under a 1/4 tank of diesel and sitting on a hill this can cause flame failure.

[Pure Glass]

No diagnostic lights, just smokes loads and then dies

Won't hold a high temperature-tends to only get to about 55 degrees and then gives up

I got mine March 11,Webasto 9 KW 2 man system.Isn't there a yellow light on your door near the temperature display?

[Pure Glass]

Sorry mate-perhaps I wasn't too clear.

There is a diagnostic light, but it hasn't been flashing or giving any indication of any problem

That burner is in faulty and P.F. wont know how to fix it, the only people who can are  Webasto Agent.
I had the same problem like yours and was smoking, when I bought my system from P.F. and they didn’t have a clue until I found a webasto Agent who checked it with his special diagnostic equipment and said that the burner was faulty and changed it for FREE.

Since then had no problem with my system and that was 18months ago.

Dani-top man

How long had you had yours when it started playing up?

How can I find a local agent? Doesn't give any indication in their website

Did you check how much fuel is in your van?You should have a 2 year warranty,there was a thread about this a couple of months ago.If you think you have a problem with the burner,you would be better contacting your nearest Webasto service agent,they will hook your heater up to a diagnostic machine which will tell you all you need to know,even tells you how many hours your heater has been used.

Pure glass call me tomorrow I have the pf hot system and also had a problem last month fixed it now but call me I might be able to advise

Well mine started going wrong as soon as I got it out of PF workshop, lots of phone calls back and forth and no joy, until I took it to a boat repair shop, where they fit lots of webasto burners in to boats, and he gave me a number to contact and this guy is based in Pool, you can contact him and see if he can help, I am not sure were you live but this guy should be able to help or guide you where to go.

His name: Tobby
Tel: 01202690900

This guy knows all about webasto, he is true pro.

Good luck mate.

[Pure Glass]

Thanks Dani

Really appreciate that mate

[Dani J]

Thanks Dani

Really appreciate that mate

You welcome mate    hope it will help you.
P.S. Tobby is a registered Webasto Agent.

Please let us know what the outcome is.

The motor industry doesn't have problems with these heaters but the Marine industry does.
The red diesel that the marinas supply doesn't work well with the burner as it causes it to carbon up, and the other issue is that the Webasto cycles if it just heating up the hot water tank (Calorifier) and not being used for central heating.

I haven't been following the Webasto diesel heater debate in the hot WFP industry, but a few years ago I felt the Ionics seemed to have a solution that PF hasn't used - in their earlier setup anyway.

I believe that the WFP diesel market has the same problems as the marine industry with regard to boilers cycling. This was pointed out to me by a Webasto Service Technician several years ago when I was looking at a Webasto Thermo Top C unit.

The principle in application is that the heater heats the water quite quickly (a small closed circuit) and the heater's pump circulates this hot water through one or two heat exchangers. The water for our brushes is also pumped through this heat exchanger and temperature regulated after the heat exchanger, and this is how that heats the water used to clean the windows.

I believe the problem is that heater produces far more heat than what we use at the brush head. Once the water in the heating system reaches 84 degrees it kicks back to half heat and then switches off, only to have to restart a few minutes later. These short burns reduce the life of the burner and also causes them to coke up, which sound like your problem (smoke). High battery drain is also a problem with this stop/start situation as the burner draws around 11 to 12 amps each time it starts the heater.

Ionics keep (or kept) water flowing through the heat exchanger, even when the operator switched his water to the pole off. This excess water was redirected back into the tank so would slowly raise the water temperature of that.

I am told that the 9 kva diesel heater is a better unit than the original 5 kva Thermo Top C. But I still believe that the cycling issue will be more pronounced than with a smaller heater.

If you look under webasto parts on e bay there is a guy there selling the wick for the burner which sorts the problem ,I think it costs 30 odd pounds as got it last january and webasto guy fitted and works a treat since,Hope this helps .Liam,

Firstly chaps-tanks for your responses and suggestions. Spruce-your post is spot on.

I've just got back from GTC Marine, based at RAF Alconbury who are a webasto agent. I'll try and explain what he replaced and commented on with regard to the heater.

Spruce is spot on in saying that the unit is designed to cycle CONSTANTLY. So when I turn off my pole tap, the temperature of the unit increases to 81 degrees and then cuts out to half heat as there is no water cycling through. In the marine industry these units run with a constant flow of water through them for a boiler and rads. I have the 9kw heater and this enough to run a boat with a boiler and 9/10 rads plus.

Because of the intermittent usage, my heater turned off and on 1083 times causing the burner to coke up and die. I had to have the burner unit and fuel sensor replace, however the coil wasn't required, costing £350. I will be going after webasto to see if I can get it under warranty.

Gary's comments were suggesting a remote sensor that as soon as the pole tap is turned off, there may be a way to fit a remote sensor to flip the heater over to cycling the water, or having a separate tank that has a cold supply and is drawn into the heated section like a header tank.

Te unit has only lasted 18 months which I'm very disappointed at, considering the cost. I've got to come up with some way of cycling the steer floe to keep the heater on cycling and the temperature from creeping up. Either that's or put the heater on before I go out and then use the already heated water

He felt that the 9kw was definitely over kill for the use we have and as a single operator, there were other options. I'm not mechanically minded at all, so have to refer to others expertise on this, but pure freedom seemd very resigned to the fact that this was a hazard of the unit after this sort of use. (Which I don't view as particularly excessive)

This isn't a pure freedom dig by the way, as Andrew has been great when required, just disappointed that I may have to fork out every couple of years if I keep the diesel heater.

So its not fit for purpose then ??

That's interesting,wonder if PF will take note of the findings.
I am quite lucky in that I circulate the water through the heater as I use backpacks to do my work.I run the hose fom pump 1 directly into tank,then I bought extra length of car radiator hose which I run from the van port pump 2 back into the tank.I reckon it takes 1 and a half to 2 hours of circulating(could be longer if ambient temp of water is very cold) to get a full tank of hot water.You start off with low flow rate and keep increasing the flow rate as the water gets warmer.

[Pure Glass]

Steve-sorry, can't insert your quote from my phone

I think it's for for purpose, just think I've possibly used it wrong in that I've used it on demand rather than cycling back into the tank.

What it means is that every time I finish at a house/row, I've got to get back to the van quickly to turn the gate valve so that it cycles
