I think I'd want to see a lot more detail about how they're measuring efficiency.

By measuring heat output and electricity input.

Heat output is measured by a heat meter (which has three basic sensors, flow and return temperature and flow rate).
Electricity input is measured by a power meter.

That's obvious, but whose equipment is being used to measure it, and who's in charge of the data from it? Where's the control data they're comparing it with? Then, what level of efficiency is being guaranteed, and what factors, such as indoor & outdoor temperature affect it? Their website mentions an industry standard for measuring efficiency, what are the potential loopholes in that?

"We guaranteed the efficiency at 19C mate, if you turn your stat up to 22 that's your problem".
"Our guarantee only covers an average UK winter, we can't guarantee the weather".
"The reason your new system is costing you more is that electricity prices have gone up faster than gas since it was installed, we have no control over that".
"Your old boiler must have been more efficient than we estimated, we have no way of measuring that".
"You must have changed your heating hours".
"You're not comparing like with like, the old system had a combi boiler, the heat pump uses a water tank".

Mind you if there's enough demand someone in China may start making them.

Like ICE cars gas boilers will be around for a long time yet and as a result will be supported by a spares and repair chain

Is it in good order? You soon won't be able to buy a new one in the UK.

Oil may increase in price but at the moment I'm satisfied that my heating cost won't be bettered by installing a heat pump.

Monetary costs are not the only costs. Any form of supporting the oilgassy sellers is doing untold damage of many, many kinds, which are large costs.

Of course we all support them to some degree, those oilygassers. Up to the eyes in heat pumps and solar panels, I'm still somehow using plastic; and getting things that arrive via diesel lorry, perhaps even via a ship; or s gas-guzzling aeroplane.

Still, every little helps. A heat pump is also likely to save you money too in the long run - not just by getting that free energy from the ground or air. Less oilygassy pollution might make us all live that bit longer, in better health. Bad health, before too long (perhaps even now) will cost in many ways - lost income but perhaps also the new "patient contribution" (not just our taxes) in the New Model NHS, already going to the dentist model.

I have a boiler engineer who services it every year.
Yes it's in good order and efficient.
At the moment spares are available - there are good second hand boilers and parts also available since some are being removed to make room for the "improvements" conferred by an air source heat pump.
I don't expect to be without a boiler for the foreseeable future - which may not be long given my age.

I only ask because, of course, anyone wanting to stick to oil for the next few years needs to recognise that if they are going to want a new oil boiler, now is the time.

All mistrust the level of expertise of the installers of heat source systems. Two having been bitten by early installers of double glazing.

pwa wrote: 31 Aug 2024, 11:44am Whatever happened to the idea that we could run oil central heating on carbon neutral bio-fuel, courtesy of recycled chip shop oil? I remember that being touted as an option about 20 years ago, then it seemed to fizzle out.
