The majority of Rayburn boiler failures are precipitated by cold water corrosion; A result of a failure to wire in the low limit 'stat. This combined with a propensity to skimp on an appropriate inhibitor can kill a boiler very quickly.......... I could discuss the need for 28mm primaries and...

Too many don't............................................

Please tell me you have wired in the pre-fitted low limit 'stat and included a high limit stat in your configuration....

Famous last words................................ Near the sea, never drops below 0

As you are not in a smokeless zone (most of the UK is designated as such if there is mains gas) then if the flue is compliant and your council sign off the installation as being building regs compliant you should have no issues. Of course there are non certificated buildings out there...

Minor fire in property and some damage caused by relatively recent solid fuel installation. Householder asked for certification etc. Contents not covered. At sale of property conveyancing requires cert of electric, windows and solid fuel work.....

Regs indeed do not differentiate between house and shed.......... Building Regs Part J primarily. Your 'flexi' does not comply unless encapsulated in a masonry flue. IF you are going down that route you need a twin wall, insulated, factory chimney system and comply with the requirements for...

But it is not a DEFRA exempted appliance, and as such cannot be used to burn wood fuel in a smokeless zone. The flexi flue liner in the vid MUST be encased in a masonary flue and it is not long enough to comply with clearance from combustible roof. In addition your description suggests your...

Ok. Still needs heat leak radiator of 500 watts and the aforementioned upper and lower stats. Everything as above. Cold water tank for cylinder wants to be the same or bigger than the cylinder volume. Also requires open vent to the room in which it is situated of about 11 square cms. Not big...

Just re read your OP. You are not intending to use the Rayburn just for hot water only are you? What model is it? What 'wet' stove are you taking out? If connecting to wet rads a neutraliser of some form will be required which won't like a mix of vented and unvented systems...

Primary flow and return must be 28mm. 190 litre indirect hot water cylinder, f&e tanks 18 litre min. BS plastic with lid and ply support base extending 150mm all round or galv/grp tank. Metal ball valve and float. Copper overflow at least for the first two metres preferably full length. Ensure...

Simon, there isn't one. Thanks for all the replies so far. DP, there are at least 3 rads with no TRV. I hope a shoe type valve solves the bangin' problem............. I know have the valve in my posession and it does look like a nice piece of engineering. I need to find time to do the job...

OK, if I have to provide a by pass with ABV........... The take off after the pump is no problem but getting the return in will be difficult without extensive pipework. Can the return go as the ALT. ABV POS in the diagram?

DP - old valve is probably one of the first replaceable head models. Having inspected the old and the new it would appear that the old one has a pivot that is not completely perpendicular to the top plate. It is about one degree out, which means that when the ball closes to the seat it does not...

Tower is a budget Honeywell and is made in the same factory......and has a ball. That is the problem. I believe Myson, Sunvic and Drayton offer shoe valves - Drayton also offer a paddle valve. Complicated isnt it? I used a Honeywell as replacement as my old one was a Honeywell and was perfect...

Any preference as to manufacturer? I see there are also paddle type valves. I assume they are similar to the Honeywell ball.......

Yes, the valve if fitted correctly both mechanically and electrics.. AB from pump A to CH and B to DHW

Hello! The aforementioned mid position valve has been replaced on an open vented, Y plan system with 22mm primaries and 8mm feeds to radiators from manifolds (I know). The system is clean and all radiators are new. Heating and DHW are fine, both work as required and provide required heat...
