My advice to them is to update the controls and replace inefficient cylinders. In most cases they have gravity hot water which means there is no simple boiler change.
The obligatory upgrading of the system with a new boiler, and usually new cylinder anyway, means without meaning to be disrespectful they'll be long dead before any cost saving benefit. Tibbot , 30 Aug Hello Tibbot Thank you for that and the recouping of efficiency benefits against age of user equation was foremost in our minds. Agile a gloworm of this age will prob be on a gravity hot water so not just a straight change is it. Had to talk a 90 odd year old out of changing boiler as basically they would not benefit from proposed saved gas against installation cost.
May not be the case for you, but quite often we see the kids simply not wanting their parents to spend their inheritance, which is damned annoying. But sometimes if it ain't broke Then nobody likes the upheaval, which is hard to value. As for parts - there are masses of used ones floating around.
It's a decent bet that would do it though. ChrisR , 30 Aug I can see the more "efficient argument" in terms of replacing these old boilers, but the maths does not always add up. As someone pointed out, these systems are gravity fed. As far as I know replacing with a modern boiler would require a pressurized system.
Depending on how good the pipework is, you may end up with leaks due to the new pressure. The costs could soon mount up to bring an aged system up to standard. So, new system.. What is the chance of it not breaking down or even lasting 10 years with all the electronics in even the simplest of new boilers Furthermore, I would take a guess that many people would not be recommended to retrofit in a heat only boiler or to choose the simplest solution. In most situations people are encouraged to fit a combi boiler of some sort either due to what people think is best or just sales pressure.
That just increases the installation costs further Furthermore, we have the side issue of material waste. How good is that for the environment. The fact these appliances last half the time if that before needing to be replaced.
So what is the true efficiency saving If you are planning a major renovation then of course replacing the system makes perfect sense this is what I plan to do. But if it is working fine, and you operate it as efficiently as you can good controls and insulated tank then I say stick with it until fails. Even than as someone pointed out, there may not be new parts but there are still plenty of used spares floating around So many household appliances that were once designed for lifetime use are now becoming consumables.
