How long would it take to start making savings if I changed my old oil burner for a c

NIMAN

As per title, if I changed my 16yr old oil burner (regularly serviced, going well) to a new condensing one, how much would it save me annually approx?

Is it even a wise thing to consider?

10% for boiler only change.
Look at your controls also for more.

But first money I would spend would be insulations, then a bit more insulation, and finally more insulation......
(maybe another bit of isolation if there's any money left)

Remember, if the house easily looses heat, to keep the heat you put in would be the best return on investment.
Then once thats all sorted, then start thinking about your boiler and controls upgrade to reduce bills even further.

It depends on what your make your old boiler was and if your new boiler has been sized correctly etc..,On average the new boiler should be saving you 15 to 20 percent in your pocket in my opinion

Because new Condensing boilers rarely stay in condensing all the time, I would go with the 10% mentioned above. That is for a straight boiler swap and not any controls upgrade, which could be done either way.

Btw, you mention that existing one is serviced regularly; what reading are on the printout that you got with last service?

how much are you spending on oil a year at the moment?
as stated above you are looking at 10-20% savings, this gives your potential saving per year.
next get some quotes for new boiler and heating control upgrade there are grants and carbon credit allowances you may be eligible for (be careful with the heating control grant with some older systems it can be overly expensive to install heating controls that meet the requirements)

but basically if you currently spend €2000 on oil and the upgrades cost you €2000 it could be 10 years before you cover the cost of the installation

The other side of it is that the OP's boiler is going to fail eventually or require a significant repair.

Still, getting the house as insulated as possible is probably the best way to make a saving.

Thanks folks.

I had been looking at better insulation recently.

I only asked about the condenser as I seen one for sale locally that was less than a year old, I was wondering if it might have been worth buying and changing my old one out.

The guy was selling for half price as he had changed to gas.

Folks,
while you are correct on investing to reduce heat loss from the house, spending on more insulation rarely gives much bang for the buck. In the majority of cases the heat is lost by convection (i.e. air leakage, aka draughts) and not conduction. Insulation acts as a resister in the flow of heat through a solid material but does little to restrict air flow. Very few insulation materials have any impact on convection heat loss and therefore can often be a waste of effort and money.

TLDR; It ain't all about insulation:)
