I am buying a house in a hard water area. It has no c/h system and no
boiler and I inted to install both. I gather condensing boilers are the way
to go these days, but what about the question of combi vs. regular? My
experience of a combi in my previous house was that it was constantly
furring up dure to the hard water, and I spent a fortune keeping it
running. Conversely, my parents had an old fasioned regular boiler and a
copper cylinder that never needed any repairs or maintenance. Bleeding the
rads once a year was all that was required. So, is there a good argument
for using a regular condensing boile rather than a combi? The house I'm
buying is a 3-bed semi.

If you stick a phosphate dosing unit (like a "Combimate" for example) in
front of the combi then it should not suffer scale problems. That should
then bring the decision back to the basic one of which better suits your
Things like how many people, what's the cold mains flow rate and
pressure like etc might be more relevant...

come with it; any other 3/4" Male fittings you try to use on it are liable
to strip the threads).
do a cost analysis vis a vis a combi and a softener, versus a mains
pressure system boiler without.
However I recommend a softener for all hard water areas. Its not just
boilers..shower heads, taps everything furs up and you spend an arm and
a leg descaling and repairing.
I dont personally like combis unless space is very limited and there is
only a single person or a well in tune couple. Peak flow rates are too
low frankly for all but one at a time usage.
And if you get a bigger one instead, it just takes up more space and
