Can you say whether you have 2 port valves or 1 3 port valve

You don’t know anything about me sir, so I beg to differ.

I don’t install many boilers. So what am I ? Interested

Thanks Bernard have just ordered those ferrules Thankyou all for your knowledge and help, much appreciated

The crimper I ve got is a decent one tbh, are the pin type not great ?

I was looking at the pin crimps, reason being, wiring loose threads of wire into many blocks on air pumps and boilers are difficult as the space is so small. On many heat pumps from Europe the wires come with a pin type crimp on the wire. Makes it a lot easier to wire. That’s the only reason...

Thanks rsgaz is that what I need for the size of wire I’m talking about ?

hi all I’m a heating engineer and I want to do more crimping for ease of wiring etc. Off boilers it’s is 3 core in white sleeping not grey and is about the same diameter off pumps and zone valves. My question is what width is each individual wire and should I use the blue or red pin type crimp...

Hate to say I told you so, but I put the original answer on here. Viva Worcester bosch I’m always around if you need help, I’m a wb engineer

So you are “angry with Worcester Bosch “ you checked out the water, changed the pump, then you got out an installer to service the boiler. Then you got a cheap pcb ( maybe recycled ) and either you fitted it or someone else did. This is the point that you rang wb and they told you pcb???? Yet...

The wb cdi classic is a vision of beauty and reliability....look no further than the 34 cdi classic. Fitted by a wai you ll get up to 10 years warranty

Nick, the average house kw for heating is between 5 and 10 kw. So most boilers will kill it. So you need to look at the hot water solution. To heat two showers at the same time on average flow you ll need 34 kw plus. This though is dependant on your dynamic water pressure on the incoming cold...

You can’t fit a Baxi part to a Worcester.....which model Worcester is it ?

Turn the tap down to half the flow rate....does that improve the temp ?

Phil it’s a combi, it heats up water coming in. Jan and Feb are always the worst. The boilers work on a 40 deg rise at the correct flow rate. So if your getting 9 litres a minute through the tap, and the cold inlet temp is say 7 degrees, if you get hot water at the tap of 47 degrees your boiler...

Probs control box and transformer

Go Worcester Bosch all day long, best aftercare service in the industry and cheap parts after warranty if it does go wrong.

hi all, had new windows fitted few years ago. After a couple of years the inside seal went a bit awol and on very windy days I could feel wind getting in the house. We do live very close to the sea, Cornwall so strong winds are a problem. I used decorator caulk last year but this year looks like...

Look at the flow for that boiler, probs about 8 litres per min which isn't great for a shower

Just to clarify puller old chap, I don't sell Worcester boilers, i fix them as a service engineer, I don't need to, the product and aftercare service sells themselves. If you are interested in sales though......the last 3 years all sales records have been blown out of the water. This years end...
