TVO is just vehicular paraffin.

Diesels certainly seem to have lost their rugged simplicity. The price you
pay for the phenomenal performance, compared to a few years ago, I'd guess.

My last CX left me at 247,000 miles with the engine still going like a train. It was the rusting chassis that was the problem but after 16 years I was happy enough. Current C5 is at 160,000 and looks as though the rust isn't going to be the same problem whilst the engine seems unbreakable despite having things done to it that it was never intended for. -- Alan Calder, Milton Keynes, UK.

The type of paraffin/kerosene used in internal combustion engines is called TVO. Tractor Vapourising Oil. Almost any low compression slow speed engine will work with it (a 100E would probably have been fine) but you can't just pour it in the tank and drive away. It needs to be pre-heated to aid atomisation otherwise it won't burn properly, which is probably why it made such a mess of your engine. The easiest way to do this is to coil the fuel pipe around the exhaust manifold a few times before the carburetor. You may also need to retard the ignition a bit. However the main 'problem' is that you need a small auxiliary fuel tank of petrol and a change-over fuel cock because you'll never get it to start on TVO. So you have to start up on petrol and then switch over to TVO once it's hot. You also need to switch back to petrol a few minutes before you stop otherwise you'll have to drain the float chamber before you can get started again. I know about this because before small diesel engines were common TVO was widely used in small boats and I owned a 36 ft boat with a Meadows engine which ran on TVO. -- David Holden - APDL - <http://www.apdl.co.uk>

Yes, I'd learnt this, at least the practical bits, on a farm in Kintyre with an old TVO burning Ferguson.

I'm not so sure. A decent condensing domestic boiler is very efficient -

Depending on the thermodynamic cycle employed the overall efficiency is unlikely to exceed about 45%. Then there are the transmission losses to be added. I'm rather forgetful of what was the typical cycle efficiency with coal fired stations, with high temperature, high pressure steam installations, 36-38% springs to mind. However, with mixed cycles, so called topping cycles - gas turbine generators with exhaust gases raising steam in boilers for use in steam turbo generators - I think 48% is about the maximum efficiency that can be expected. But I'm very much out of touch these days. There's been some very fancy thermodynamic cycles that have been invented over the years. The *mercury* cycle was one that always intrigued me - actually used used in Germany and the USA - very high efficiency, about 45%, I think, in the 1930's. The super-critical steam cycle keeps being re-cycled (pun intended), but very expensive, exotic, stainless steels are necessary. > I'm not so sure.

There are still some losses out the flue and condensate drain. The case of
the boiler also goes at least slightly over ambient temperature.
If measured in the old way, they actually exceed 100%. ;-)

I can't remember the details, but it was something like 100% was a point
thought to be the maximum that could be achieved in those days. Technology
caught up, so for a while efficiencies of more than 100% were quoted. A
nonsense, of course.

The other issue is that using gas for space heating splits the energy load across two supply grids. The more that end-use energy consumption is moved over to electricity, the more that one grid - the electricity grid - has to take all the energy load. A grid built to supply 60A per house steady load, 100A peak load not all at the same time. It's already happening as people are stampeding to buy more and more electrically-powered cooking devices.

Yes, but how long do you have the kettle on for, and how long do you have the electric grill, chip fryer, sandwich maker, etc. on for? I have about six cups of tea a day, each time the kettle is on for about 60 seconds, so that's (checks kettle) 2200W x 6 x 60 seconds per day, 13200 W-minutes, 0.22kWh. > I think the problem is the stampede for "ooh shiny".

Kettle takes 2-3 mins to boil. Plus well water in the other kettle for hot water bottles, it's even slower. The electric cooker (tabletop thing) heats up quickly and flicks on and off. Doing a pizza is perhaps 20 minutes use of which it is on for maybe 12 or so. Rating 2kW. Don't have a fryer, nor sandwich maker. Don't use George much either as I only did burgers on it (I couldn't bring myself to pass a decent piece of meat through it given I prefer slow fry for tenderness and George is anything but slow). The heaviest users are the microwave (800W output so maybe 1kW in all) and the rice maker (600W). Both of which could be fairly easily replaced with my small bottle gas stove if necessary. Hell, during a power cut I've boiled up Evian in a saucepan for my cuppa. :-) > My radio currently isn't working, and I'm guiltily listening to the > radio via the TV ! :( :( This is where a reasonable set-top-box is useful - audio output sockets so can easily plug into any hifi with aux inputs. That said - have you looked to see if the radio channel you want is available on-line? I've found my phone (!) makes a brilliant mini-terminal. I'm writing this to you and listening to AnimeNFO at the same time. There's an app for BBC streams, so it's all much more flexible than a stand-alone webradio box. [it even does streaming TV, I watched a docu on NHK World last night, but the quality/capabilities can be quite variable, my sat box is better plus I can record that ;-) ] Best wishes, Rick.

If you have replaced an older one with a condensing boiler, they run at a
slightly lower temperature for the condensing mode. This may mean
increasing the radiator sizes if the originals were marginal. But after
this you'll still get the benefit of a much more efficient boiler which
uses less gas for the same heat output. Maybe as much as 20%.

According to my builder/plumber friends you also get a very much reduced boiler life with condensing boilers compared with the expected life of the older cast iron boilers.

Depends very much on the quality of the one you buy. But the life of any
boiler only expires when spare parts are no longer available. Condensing
boilers are more complicated than older ones, which needs more skill when
fault finding. Sadly, electronics (and electrics, come to that) are likely
to be a black art for most repair types.
