Choosing a boiler - again.

Mad trolls usually do.

Try another make. Duh!!!

Now I've finally got their PDFs to work it would appear the Vitodens 300

I'm a bit confused about which extras are needed for installing on an outside wall - I've not really waded through the options. A recommendation as to where to buy would help too. This is the best price I've seen so far:-

Take a visit to Television Centre. It's on the guided tour past the studios, as is the control column, unless they've moved it in the last year or so.

Like yourself you mean?

If anyone on this group knows anything about what the TARDIS was made out of Mr Plowman will, seeing that IIRC he worked on the some of the original productions.

Don't suggest that, he will be like Frank Spencer in the ultra-modern house! - if you remember that episode. Must say, it would boost ITV's viewing figures with the entire BBC off air...

Such wit.

Heh heh. Most TV chippy shops only use blockboard. MDF and chipboard have H&S issues.

Duh yourself. Not noticed you being any help - as usual.

I worked on Ep1. Which was made twice by different crews in different studios. Don't know which one got transmitted. I do remember my crew thought it rubbish and would never make a series. Also remember Hartnell being a miserable sod.

I am helping you no end.

Given your encyclopedic knowledge of maker's catalogues I'd have thought you'd have been able to offer me several choices of what I want - rather than what you think I need. But then I should no better than to expect this.

You are an ungrateful plantpot.

Or could use RAVV with a 2-way valve body such as RAV, VMT or VMA.

Using a 2-way valve body may stop pump flow 100% with the pump pumping on nothing. Not good. A 3-way diverts the flow to ensure full flow. A 2-way could be used with a flow switch to switch the pump off if no flow. It may work out cheaper that way. Or use a Grundfos Alpha pump. Not sure how the Alpha would respond - it would need a mock-up and observation to observe the DHW temp stability.

This also ensures that the returned water is quite cool too keep the bottom of the cylinder cool which is good for condensing efficiency.
