Loft conversion/ new boiler

[Slogo]

Hello all

Anyone got any experience of living through a loft conversation where the plan is also to remove the loft tank/ traditional boiler(sited downstairs) for an eventual combi.
My idea was to live downstairs during the loft conversion, then live upstairs once complete where I have planned further works( layout reconfiguration/ wall knock downs) of ground floor.
My concern is that the initial removal of the tank will render the property with no heating for a considerable time which I really want to minimise.
Strategy for this ? Boiler works in parallel with loft works? Looks like my works will hit winter so bad timing..

Many thanks

We put the upstairs rank on flexi piping and it got moved around a lot before it was finally scrapped to minimise disruption. We bought ceramic heaters for the lounge and bedroom when the heating needed to be off.

@TWmover - thanks for the great advice

I bought a couple of crappy 2kw electric heaters to keep the place ok when the boiler blew up.

With the gas fire in the lounge it was enough.

You used to be able to get them for about £15 but now they are about £30 on Amazon. Bear in mind the electric cost is 3x the gas so they are not cheap.

Electric blankets for the beds as well.

We installed a new heating system about 2 months before the loft conversion. We installed an unvented tank replacing the old tank and rendering the loft tank redundant. Our plumber installed the bits of plumbing for water and heating for the eventual loft conversion. Our builder then just had to cut the old tank into easy smaller pieces and chucked it onto the skip.

It is probably worth you deciding what system you are going to install when you remove the old system. Then work out where you want to install the new boiler/tank and get this done sooner. It is like knowing where you want plug sockets in your new loft as you also have an idea where you will place the bed.

As for the work you are planning to do, if you can afford to do both loft and downstairs, then I would do the work downstairs first; particularly if you are removing load bearing walls and installing steels. There will be movement and settling cracks in the upstairs walls when this is done. We could only afford to do the loft conversion as we really needed more bedrooms but we are aware that when we get to do the downstairs, some damage will occur in our lovely loft walls that we shall need to repair/decorate.
