Oil boiler and aga

Brettgolfer

I have a Camry 2 boiler which is 25 years old and "appears" to be running well.My oil usage last winter was huge.My property is 4-500 years old with a modern extension.We live in 6 out of 12 rooms as there are only 2 of us now living here.The old part of house is much colder than the new.
I propose having the system flushed and new rad.valves fitted and turning off rads.in rooms we do not use.
Should I replace boiler with different economical system?
Any help welcomed.

A camray 2 is a reasonably old boiler so not built to be as efficient as a modern condensing boiler, most likely it is on pumped heating and gravity hot water with limited controls which will also not be helping efficiency.
A modern good quality condensing boiler and an upgrade to the system and controls will obviously help cut you oil usage, however there will be installation costs to take into account.
Your post title mentions the word "aga" however no aga is mentioned in your post, if you have an aga I would also be looking there for a reason for more oil usage, after all nobody leaves an electric cooker switched on 24 hours a day 7 days a week, that will be where a good proportion of your oil is going

Thanks.See edit re aga.,but no change in usage over the years.I'm looking for advice on best modern boiler system.

In that case a good quality condensing boiler (Grant's are good) update system from pumped heating / gravity hot water to fully pumped system with zone valves on heating & hot water, twin channel programmer, room thermostat, hot water cylinder thermostat and TRV's as required (all bedrooms as minimum).
Power flush system at time of work and fit magna clean or similar to provide ongoing protection.

I'm not sure a condensing boiler is the answer for an old house. I wouldn't dream of it in ours.

But certainly zone valves for upstairs downstairs on thermostats are worth looking at.

Check out the prices between oil and gas also.

A system flush could well cause the old boiler to leak so don't do it just before winter! Or be prepared!

I do not understand your comments about the condensing boiler. It is the heating system not the house that limits the efficiency of a condensing boiler.
