Interesting progamme. Just a few comments:- 1. The `horizontal chimney' works due to the intense heat in the vertical portion of the system 17:28 as well as due to the fact that the flues are balanced. Later boilers (1980s) have a high temperature fan on the outlet side of the boiler to enable the balanced flue to be smaller and less obtrusive. 2. The solid fuel boiler used is a very old 1950s design of low heat output boiler with no heat exchanger above the fire. There were better designs available at the time with the (usually cast iron) heat exchanger extending above and over the fire (e.g. Ideal made boilers with 2 doors in the vertical front of the boiler, the top one to put the coal in and the bottom one to take the ash & Clinkers out). The top door had an air vent hole with a variable shutter to allow some air to enter above the fire to enable the flamable gases produced when heating the anthracite to be burnt (with a nice blue flame). 3. The oil fired boiler is shown incomplete to show the burner; so unfortunately the heat exchanger detail towards the top of the boiler is not clear. This would show how these boilers were in the order of 75% efficient (while firing, the seasonal efficiency will be lower) although in my view this did vary from manufacturer to manufacturer e.g some had an integral draught regulator, others didn't. The draught regulator prevented a hot chimney from pulling excessive cold air through the boiler & burner (it was just a counterweighted air flap). Also some manufacturers used a lump of `concrete' like material in the top baffle that took ages to warm up which was obviously inefficient and finally some manufacturers insulated the boiler shell with fibreglass wool or similar while others didn't bother. The oil boiler shown is a Wilson Wallflame 60 (60,000 BTU/hour output) manufactured in Kirkby, Liverpool, UK 13:27 BTW the wallflame burner is a late 1940s American design (Timken) that usually burns Kerosine (Paraffin) although it can be modified to burn gasoil (Diesel oil). heatinghelp.com/assets/documents/108.pdf 4. Tim must be a nice guy judging by how the cat starts to purr when he sits on the sofa ! 0:58 Edit As an aside I've always been interested in domestic boilers, in particular oil fired. We moved from London to a new house just outside of Maidenhead in mid 1959 when I was 2 1/2. The house featured part oil fired central heating `that required no stoking' which was really new in the UK then. The Wilson `Oilheat' 35,000 BTU/hr boiler (that came out in I believe 1957) had a vapourising wick modulating burner like an Aga cooker and the CH was pumped with gravity feed to the HWS tank in the airing cupboard. There were no controls apart from the modulating boiler thermostat made by Teddington Controls (I see they're still going in the UK btw) and a manually operated switch for the pump if CH was required. The USA had oil fired `Wallflame' boilers from the late 1940s / early 50s but Wallflame burners which were on / off, fan assisted and thus fully automatic and far more efficient (due to better excess air management) only became available in the UK in the early 60s. Worcester, Henry Wilson & Harford Unical (who made the BSA Hotspur) were I believe the main manufacturers to incorporate this new American burner into boilers over here in the UK.
Some more random info .... I had a floor standing Thorn `M' 38/54B gas fired boiler for many years (it was about 26 years old), I remember that the burner made a reassuring roaring noise and the flame looked very clean. Having cracked an egg on the flue collector after the burner had been running for 15 minutes (to allow for the cast iron boiler skin temperature to stabilise) it not only cooked the egg but burnt it completely in seconds! (I had fitted a baffle, intended for the open flue boiler only, in mine for improved efficiency which would have the effect of increasing the flue temperature due to less excess air). I speculate that cast iron boilers become increasingly inefficient over the years as the iron develops a thick skin of rust that can’t be cleaned away using standard flue brushes. As is common for the British if it ain't broke don't fix it attitude because the cast iron boiler lasts we were slow to innovate beyond these boilers; however there was the non condensing Abergas (made in Abergavenny, Wales, UK in the late 60s) that was very efficient (featured on TV - `Tomorrows World') but these were intolerant of poor installations that caused over heating (very low water content boiler). It took Continental Europe to introduce condensing boilers in quantity, I believe the Dutch were amongst the first. Having confirmed that the efficiency was not the best (I had also noticed that the boiler flue never produced `fog' even on start up) I replaced the Thorn `M', although still working, with a Worcester 12Ri (12kW) condensing basic boiler for improved efficiency; this new boiler has been 100% reliable over 14.5 years, I can't recommend it highly enough. P.S. The Thorn `M' cast iron heat exchanger had considerable heat capacity, so much so that a 10 minute pump run on was still cost effective imo.
18:25 I have just moved into a gas-heated house from an electric night-storage house and for once in the middle of winter I'm living in a warm house :D I would never go back to electric heating and it's insanely expensive too. Gas condensing boilers ftw!
I will never tire of this guy going on about how even though the new thing is cheaper, easier, and invariably has a better end result, that the old way is best. "yeah, now we need not rely on hordes of servants and materials, but this old cottage is coooooool".
Ascot Gas Water Heaters Ltd. was founded in London by Dr Bernard Friedman (who had earlier been importing water heaters and cookers into Russia). It was an agency for selling water heaters made by Junkers of Germany. To begin with the heaters were labelled thus (Wikipedia). 15:17
Yes it has - condensing boilers are > 90% efficient when in condensing mode (low return temperature) and approx. 85% when not. Old boiler heat exchanger materials such as carbon steel, copper could be corroded by the condensate obtained from cold flue gases and boiler manufacturers designed the burner output to match the heat exchanger so that condensation within the heat exchanger never occurred (apart from briefly on start up). Also on open flued boilers some heat was required to make the chimney `pull'. Modern condensing boilers have the condensing heat exchanger constructed from e.g. grade 316 stainless steel (especially for oil fired boilers) or Aluminium alloy treated with Silicon. It's interesting how the addition of Silicon into the melt for an aluminium heat exchanger has proved so successful since I believe that Aluminium rots badly in plain water without such treatment.

Frank Cabanski its just one of those things that have stuck over the years todays method is bring a fucking lighter something which most preppers dont seem to grasp theyll carry 10 different fire starting methods for redundancy yet the lighter never makes it in there
Crabby Old Gamer true i even watched one prepper take a bic apart and carry just the flint wheel to start fires i was like srsly would it oh killed you to take the rest of the lighter
Funny to see, that what we see as garbage to day. Actualy gave us cheap energy and function without electric sensors telling the schoolgirl our 5xxxxxxxx year old plenet is warm becouse of us.
One of the best series ever made!
I agree.
Same
You got that right....Tim is really amazing at what he does.
absolutely love this, no unnecessary over the top drama, just pure entertainment, love the animations , just classic.

Wow.... The third in a row..starting to binge watch I think.
Love this show.
Pink Floyd?
Yep.. Dark side of the moon..
Best album of my life....
low fi, no youtuber gimmicks and excitement. I love it.

According to the UK government we're all going to have to throw away our fossil fuel fired boilers soon !!

…just missing a notch in the timber under the bow-drill to let the hot ash collect.
Pity no mention of combi boilers - probably prog made before they were popular.

I love cats. Tim's certainly a cat fan as well.
This is Tim Hunkins programme he has a TH-cam channel should you be posting his videos?
Looks like these were recorded on film or video.
When were these first broadcast?
I remember watching is in 1980s when it first aired on discovery channel...
Best show of the eighties and to this date nothing even comes close.
that cat is a superb actor :3
If you listen carefully you can hear the cat purring soon after Tim sits on the sofa !!
That cat needs a bucket of water dumped on its head!

good show but your volume is way too low
I need to download from the album THE SECRET OF THE HEARTS tracks inside is I am trapped by col Abrams ,all fall down,Zanzibar & etc.
