OK, our boiler's goosed. It looks like it's rusted away and is now leaking. Was a fairly old one with an 'always on' pilot light.
We have two choices - replace with a new type conventional boiler keeping the hot water tank or replace it with a modern combi and do away with the tank. There's only 2 of us in the house most of the time so I'm thinking a combi might be the way forward.
To add to the thinking, we have a tank driven shower in our en suite that doesn't have much pressure - most of the time it feels like you have to run around under it to get wet. Would a combi make it any better (or worse) than what we have already?
What say you boilertrackworld hive?
Buy a woodburner and "curate" your water on top in a galvanised artisan bucket
Thanks Percy, I do quite like the look of this but I'm not sure how practical it'll be for my 6.30am shower??

Practicality be damned! This is STW man!
General consensus after talking to various heating engineers on site was to stick with what you have. So replace a combi with a combi, tank fed with tank fed.
If your shower flow is low you could add a pump to the shower(tank fed systems only).
As for boiler makes the ideal logic range seems well regarded and is what we went for in combi. 7 year warranty.
Also might be worth adding a magna clean to the system at the same time. Easy job when combined with a boiler change. It's basically a strong magnet in a removable tube that stops all/most of the sludge getting into your fancy(delicate) new boiler.
I'm a sparky not a plumber so all advice above is purely 2nd hand and may be wrong.
Appreciate the advice. Yes, we were thinking of a pump for the shower before we found out that the boiler was knackered but it beat us to it.
Mrs C is preferring the idea of a combi thinking it might help the shower but I honestly don't know if it'll make any difference..... decisions decisions....
The more powerful the combi the better the shower flow is my limited understanding. This may mean you need a bigger gas pipe from your meter to the boiler. If they are next to each other fine but if the gas meters on the other side of the house...£££
A new shower head might actually help, one designed to work at low pressures.
One advantage of tank fed is they usually have a immersion heater for a back up in case your boiler goes on the blink.
A combi will improve the shower , as its mains pressure.
You will need new pipe work from combi to shower though .should be the first pipe off the boiler as other tap use will interfere with the shower .
The best all round is a new unvented "megaflow " or similar .cylinder to store hot water and under pressure. So good shower power . Will do away with water tanks in loft as will a combi. Which is always good .
You also might benefit from a fatter cold water pipe to the combi.
I know we could do with one, but it will have to wait for the whole house to be re-modelled.
Ohh yes the megaflow unvented is supposed to be very good. Couldn't remember the name of it.
