New central heating / water controller

newboy99 · 10 Oct 2010

Hi Guys
I need to replace an old 'Boss Therm' central heating controller which is 'on the blink'.
Probably over 20 years old and I can't find any Google references for it.

Am I right in thinking I can use any one of the 'decent' controllers sold by Screwfix @ c. £80 ?
Also, any tips or things to watch out for ??
Many thanks for your help

Tips or things to watch out for?

Don't pay eighty quid for a controller that should cost you less than half that price!

Possibly due to the newcomer here ^ who clearly doesn't know the use of the question mark - or indeed, how to stay on topic for the sake of the O/P.

I haven't got a friggin clue as to what you or our 'friend' in Zaire are on about.
Perhaps it's me ?

Newboy99: If you'd care to describe your current system, I'd be pleased to advise you on a suitable replacement controller - at possibly a fraction of that cost that you mentioned.

My former posts were directed at others here - and not to you -just so we might stick to the original point.

Read post No.3, and you'll seee what I mean.......

Thanks Lucia
The system is a standard combined hot water / central heating system.
There's a wired temp. thermostat in the hall and an upstairs hot water cylinder fed from a cold water tank in the loft.
I believe the central heating is of a standard 'indirect' type, the boiler is about 7 years old,
plus of course the usual pump and motorised valves etc.
I really just wanted to check that these sorts of controllers are fully interchangeable or whether there are likely to be problems switching over.
British Gas have quoted £168 to do the job but I'm just wondering whether if I buy a suitable controller, my local 'Sparks' could be expected to do the job for me ?
Presumably there's no 'Gas' knowledge required.
If he can do it, I can't think that it would take more than a couple of hours for him and at his very reasonable rates, I reckon I could save £80 - £90 !
But then I haven't got shares in British Gas !
Anyway, appreciate your comments and thanks again for your help.

PS : where the **** is Zaire - and why ????

If BG are quoting £170 you can almost certainly save a great deal by using an independent or diy. Unfortunately there is no such thing as a 'standard combined hot water / central heating system' we will need more info. I just bought one of these for my combi boiler: http://www.heatmisershop.co.uk/products/Programmable-Thermostat-%2d-Heatmiser-PRT.html which is a combined room thermostat and central heating controller. A model which can control immersion heater cylinders (hot water) is also available, as are cheaper but less pretty alternatives.

nb99: This seems a straightforward replacement part for an orthodox system - and should be simple plain-sailing for either you, as a DIYer, or for your local electrician.

A standard 2-channel programmer (eg Danfoss Randall) should cost you not much more than £32.00. Almost any programmer will do you, for this basic task.

If you'd like to tackle this as a DIYer, I'd be pleased to advise you further, step-by-step........

Many thanks Lucia, that's a big help.
I'll talk to 'my electrical man' and see what he thinks.
Thanks again !!!
