Hello all,

I think I need to to make a decision on the current heating system.

Currently I have a Keston 50 boiler working a non vented heating and
hot water system in the bungalow - all installed new in 2000.

Last week I noticed the hot water cylinder has developed a leak (small
drip) but the cylinder is an Oso with a RRP in the order of 900
pounds (I can source one for about 600 though) plus the labour to fit.
These cylinders now have a 25 year guarantee (but mine only had a 5
year one) so I put the failure down to one of those things and just
get on and replace it.

However life being what it is the heating did not come on this
morning, the mains supply fuse had failed.

I lifted the cover off the boiler and saw water dripping out of the
air intake filter housing, it was raining at the time and the intake
rises vertically through the roof approx 1 metre. I dried the small
amount of water out with a piece of kitchen towel and used a hair
drier to finish off the drying. A similar thing happened 2 years ago
and the gas valve had to be replaced at about 300 pounds.

So the decision I am considering is as there are only two of us living
here in a 2 bed bungalow using showers rather than baths should I
forget staying with a non vented system and replace the Keston with a
new stored water combi using the cylinder replacement cost to offset
the price.

We had a french combi years ago and hot water in the summer was
lethargic but I understand things have improved since then.

Any thoughts to help my aged brain make a decision?

Dave
