"wear" after the river :) Yep that's where I live. Jarra born tho

dhw microswitch assy for the eco is what you ask for, it comes attached to a full wiring harness including connections to the pcb, selector switch, terminal strip and pump. You can do a shortcut by cutting the wires of the microswitch and just replacing the switch. I like to do it the proper...

ufh in a correctly designed system should be better/more efficient than rads. I know!! I live with it!!

The one you've got will be badged as range but it's a sunvic valve. Range don't do them anymore they use Danfoss. Ring Range and they'll supply you with the correct replacement. You have to buy it in 2 parts, the water section and the actuator.

the 100 doesn't claim fuzzy logic (but may have it)and the presumption that your control is faulty is purely speculation on my part. I think you need a Viessmann wizard on site.

The Vitotronic 150 is continental. In the UK it's known as the Vitotronic 100. I'm pretty sure they're one and the same. If so then there is no function code to have the pump in an always on state. You can only adjust the run-on up to 15 minutes. The control also has a function that spins the...

get the diaphragm pump out and you'll find the little white elbows are cracked. Take em off and toss em, pout the pipes back where the elbows were. Reassemble taking care not to kink the pipes. Unfortunately you're gonna need a RGI to set your high and low gas pressures back to what they should be.

does that price involve you having to sign up to a service contract for a year though? That monthly payment adds up to a lot over the year!

Just a note on the necessity of the baffles. In 98 I installed an Excell and from the get-go it had explosive ignition. Investigated all the usual, pilot size and configuration, gas pressure etc. Called out Vokera and the first thing he did was take out a baffle. I quizzed him on it and he said...

The flue should rise from the boiler to outside so any condensate falls back into it and not out onto the floor. If your boiler has a huge plume then it's probably because the ch is turned up high. This stops the boiler from condensing and increases plume size.

if you do get the injectors and manage to convert it don't forget to change the hose to a LPG hose as well!

you'll probably find it's coming from the auto air vent. check it out.

i've had this Kal. Was advised by Vokera tech to change ignition electrode to a different one at the same time as changing the pcb. Give them a ring again and quiz them about the electrode prob. They couldn't tell me why just said "change it".

i've now lost count of the amount of frozen condensates i've been to in the last 3 weeks

possibly the dhw pin on the diverter valve stuck out a bit. You'd get hot water ok but not ch

check that someone hasn't knocked the gas tap at the meter making it partially off. Not enough gas would give those symptoms.

01 is ignition lock out. Check firstly to see if the gas to the property is switched on. I've known lots of gas meter taps that get turned off by mistake. Are you on a prepayment meter??? These have an anti tamper device inside which means a good knock turns them off, it would show "off" and...

as far as i'm aware the "hybrid" controls were only on the 242 & 282 "e" models. The new plate heat ex kits fit regardless of hybrid or not.

dripping hot taps can cause the problem too. They stop the wax capsule from getting the right heat readings to tell it to move.

sounds very much like it bout £40 last one I bought.
