I'm seeking advice.

We're currently looking to replace our system boiler and hot water tank.
The boiler and tank are too small for our house (detached, 30s, 3 beds,
one bath, 3 downstairs rooms with small kitchen extension).

We've had a couple of heating engineers in and are receiving conflicting
advice; as I am sure I will get here!

First chap said that a combi would be no good for our house. He said he
would never use them and that they are no good for a house of our size. He
also said that we would need to replace our old iron gas supply, even
though it appears to be large enough.

Second man said that a combi would be fine, he recommended a
floor-standing, Worcester Greenflow. Said we wouldn't need to replace the
gas supply it would be fine. Said a wall mounted boiler would not be big
enough. Having a floor standing boiler is less than ideal as it would take
up much needed floor space in our small kitchen.

Third man says we would be fine with a wall mounted combi but said we'd
need a new gas supply as old iron pipes a likely to rust and this can get
inside the boiler. He also said they are prone to cracking and leaking.

What we would ideally like is: a combi, wall-mounted, with no new gas
supply if possible. We are a small family (2 little kids), with not a lot
of spare cash, and not a lot of room in our kitchen for the boiler.

I know that, ultimately, the decision is ours but if anyone has any advice
for us it would be much appreciated.

thanks in advance, dan

I saw a great set-up the other day...

Unvented cylinder, heated via solar panels (actually evacuated tubes), which
then passed through a Worcester condensing boiler for DHW. The boiler
simply topped up any heat demand required. The cylinder sat at 25c even in
the winter, therefore using a lot less energy to satisfy demand. Also had
an immersion in case of boiler problems.

Probably not that rare - first one I've seen though.
