Combi boiler and water tank

[Kizziebel]

I have just received the survey back on the house I'm trying to buy and basically the tank in the loft has been condemned. The boiler is also old with a vented hot water cylinder both of which are in the second bedroom.

The surveyor has suggested that the best solution would be to change the boiler to a combi boiler, remove the tank and the cylinder and relocate to the kitchen. I knew the boiler was old and I was planning on changing it anyway, it's a 2 bedroom house with 1 bathroom so a combi is fine

My questions are....

It's a mid terraced victorian house, attached to the back of the kitchen is a lean to structure so I'm not sure how I can put a boiler in there as there is no outside wall immediately available for a flue. I'm sure it'll just be easier to change the boiler and keep it where it is, it's hidden away in a cupboard and the flue is already there, is this a bad idea?

I think the bathroom is served by the water tank in the loft instead of direct from mains. If I removed the tank from the loft is it simple for the mains water to be directed into the bathroom?

Are there any other things I need to be mindful of?

Thanks, I've been googling but as I don't know quite what I'm asking it's just confused me!

Can it vent above the lean to? I don't like boilers in bedroom - noisy and just takes up valuable room.

Thanks, I'm organising another viewing to see where I may be able to move the boiler too.

Is it easy enough to reroute plumbing so everything comes off mains supply?

We recently changed from a tanked boiler to a combi. You will need new hot water pipework going from the boiler to the nearest / most convenient hot water tap. For us, it went from the boiler cupboard downstairs up through the ceiling and under floorboards to the first floor bathroom (specifically the bath). Once it’s hooked up in one place, it will feed the rest of the house’s hot water pipes.

Carefully consider the implications of a combi boiler and losing your tank. In future you could get solar heated water - but only if you have a tank. This can run direct with water panel on roof or spare electricity from solar PV panels.
You can get unvented cylinders (don't need roof tank) with system boiler. I'd get quotes for both that and a combi and weigh them up.

Thanks @ForestDad that's something that never even crossed my mind, solar panels are something that interest me greatly although I won't be able to afford them for a while

@MsShopper Thanks, that's something to bear in mind, I'm not sure if I want new hole made in my ceiling / floor but if the boiler went in the kitchen at least the bathroom is above it.

Did the cold water just get rerouted to the mains with no issue?

I don’t know about the cold water, sorry. I’d assume it followed the same route as with the old boiler set-up.

I've got a combi boiler in my terraced house it was installed in the roof space so easy to vent.
