Why Bother ?

[dfairclough1]

Been planning on changing our existing floor mounted Ideal Mexico (FF460) for a wall mounted condensing boiler.

Short list is as follows :-

Veissmann 100W Compact (18Kw Heat Only)
Vaillant Ecotec plus 418
Worcester 18Ri
Glow Worm 18 HXi (Which from what I've gleaned from these pages is the Vaillant with a different badge !)

Efficiency of our current set up is band D (approx 78%) so with a new A rated condensing boiler could perhaps save an additional 12%. Current gas bill averages £70 / month so potential saving of £100 /year.

When I balance this against the cost of replacement (£1500 - £2000) it could take 20 years to be cost effective assuming a new boiler lasts that long (which I doubt).

Current boiler hasn't missed a beat in the 6 years we've had it and I'm starting to think if it's not broke why fix it.

Just wondered if anyone had any thoughts on this or any of the boilers I've listed above.

Thanks in advance.

Keep your boiler.

Leave the Mexico in, it,ll out live all these new poxy condensors.

Youve only got to look what happened to most of them this Winter, froze up.

An accountant has already done the maths for you, and come to the same conclusion.

Even with the £400 from the scrappage scheme (which yours doesn't qualify for), he couldn't get it to make sense.

If it ain't broke...............

I wouldn't replace it.

Probably only because the condensate was installed wrongly in the first place
