Replacing an oil boiler

[Mike Rabbit]

Hi,
Hoping for some help. My old boiler, which has served me well, is now leaking water so has to go. It's a Trianco eurostar 50/60 about 20 years old, so can't moan with how its served us. The house is quite big, 5 beds, 3 bathrooms, in total 15 rads. So I was surprised that the output of the boiler was only 19kwh. It runs with a boilermate 2, and that seems to be working fine. The boilermate states the boiler should be set to maximum pressure.
I now have to buy a condensing oil boiler, and am wondering whether that will work alongside the boilermate. If so, how about going up to Worcester Greenstar 18/25? Would I then run that at maximum pressure (25) which is more than before?
Any help appreciated.
Cheers
Mike

What is this pressure that you keep referring to ??

Hi Terry, on the boiler. Having it on the maximum setting.

I think you would get away with running that at mid setting.Bob

Thanks Bob. Can a condensing boiler work ok alongside a boilermate II?

Youll have to get the installer to check.Bob

It will work but the return temperature is likely to be too high for the boiler to be running in condensing mode for long.
Boilermates say run boiler at max flow temperature because the store needs to be around 80 degrees to perform fully.

Thank you. So am I right to assume that the boiler should work 'problem free' but not as efficient as what the manufacturers state? If so, that's fine, as I do intend to replace the boilermate next year. Cheers Mr Owl

Correct, Mr Rabbit. It will.work fine but won't condense very much. No corrosive condensate will be produced and the boiler may well last longer as a result

Don't be drawn in by Worcester marketing.
I have an old oil boiler too and will be replacing it with a Hounsfield oil boiler when the time comes. I will run that at max temperature too....

Thanks for this, much appreciated. I will look into other models and indeed the Hounsfield. 18-25 seems to be right for the house and the possible boilermate replacement, would you recommend running it on 25kwh with the boilermate? Cheers Mike

I have a houndsfield every time old boulter engineers who know how to make boilers.Bob

+1 for Hounsfield - very good boilers, cheaper than Worcester, quieter than Worcester, and no nasty cheap plastic components unlike a Worcester

 

[oilboffin]

All in all muggles a well built boiler eh.Bob

 

[muggles]

Yep. Got one myself, very happy with it
