If you're super poor and/or vulnerable, you can take the single room heating method to it's logical extreme and use insulating materials (blankets, cardboard, etc, etc) to reduce the space you're heating within a room. A blanket kiddy fort around your bed, for example. I think this is why four poster beds hung with heavy tapestries were so sought after in draughty old castles!

Dr Jake, I have an energy consultancy business and my life revolves around commercial and industrial energy efficiency. Your return temperature to the boiler is lower to keep the boiler in condensing mode, improving efficiency. It can also reduce pipe work losses and localised overheating, especially where TRVs are faulty. Adding a weather compensation module to your boiler is an excellent way of achieving this goal, but works best in houses with 24 hour occupancy due to slower response times. Consumption is measured in kWh and not kW. Don’t compare the maximum output of your boiler to that of an electric oil rad. The boiler will modulate its output to maintain a flow temperature and so will be nowhere near that max for a majority of time. With electricity being 3-4 times the price of gas, you’d likely be able to heat your whole home for the price of boosting one room and keeping the rest to set-back temps (house size and insulation assumed for a typical house). Combi boilers are rated even higher for instantaneous water generation, so this is even more misleading. Anyway, good luck everybody of the coming months and years with energy bills, I think we need it!

I’ve not watched the video yet but I can see he has a heat only only or a system boiler. His hot water won’t reach 60c if the return flow is too low. I’m sure his ideal boiler supports hot water priority so the 2nd switched live will trigger for hot water and run that at full temperature for the hot water tank only.

I don't deny your explanation of how boilers work. But, to be frank, I don't think it adds anything to the discussion. I do still think there's a balance to be struck between using gas central heating to keep a house at tropical temperatures and just keeping yourself warm, by some other means. My electric (non-oil) rad modulates its output too, and my gas bills would certainly suggest that my brand new boiler is operating at 15kW a lot of the time. 1 kWh is 1 kW of power consumed for a period of 1 hour. I'm not, as some have suggested, saying that electric heaters are a cheap and efficient way to heat your entire home.

Hopefully someone who knows about this can confirm but I was always told that the problem with trying too just heat one room is that the room needs to be fairly sealed. If you leave the warm room in to a cold room (say to put the kettle on) the warm air will rush in to the cold room and warm the ceiling area, this will force the cold air in to the warm room and cool the floor area (where you are going to be sat). I think the heat just the room you are in is an old fashioned idea when houses where heated by multiple fire places around the house. I think the only way now is to let the house be cooler and wear more appropriate clothing. The additional problem this year is the increase in working from home. We now have to warm 20 houses instead of 1 office.

It's old school to just heat the room you use. It was very common here where I live in north Sweden where you can find big big houses heated with wood. The common frase was "close the door!" They even taped doors and windows. Relatives and animals lived in formations, to save energy. Since we are close to the energy we don't suffer of the energy crysis. In south Sweden the energy costs 20 times more!

Lucky in that I prefer a cooler temperature but the best investment I made a couple of years ago was a dressing gown from Asda. 2 in the house and both the same preferring cooler temps so the temp has to seriously drop before the heating goes on. Don't have any automated heating as we just switch on when required. Don't have it coming on in a morning as its up, dressed out to work so not putting the heating on just for the 20 minutes before I am out. I believe renting a council house does have its plus points as the have to stay within strict regs. They put the pellet type insulation in the attic about 20 years ago but this is no longer classed as sufficient so the rolled stuff went in on top (double insulation). Cavity wall done about 20 years ago also. Combi boiler was fitted about 8 years ago and gets yearly checks (done this week), its also modern enough that it will send a blast of heat through the system if chance of freezing. Modern double glazed windows / doors all round.

It’s ok to turn the boiler down to 60 degrees … any lower and it will become difficult to get your hot water up to temp. Another point I’d like to make is the boiler won’t run at 15k continuously as it will modulate down to around 3-6kw/h depending on the boiler model

We did all last winter like this, and we had windows on the front with big gaps round(now fixed btw). Ours is a draughty Victorian 2 bed house and on this system our house doesn’t drop below 14c and the rads only come on for an hour in the morning. I’ve thought about getting an infra red stand alone heater if we need it. Having one room nice and warm keeps the family together

The warming effect of CO2 declines as its concentration increases!!! Climate scientists have determined, and both sides agree, that the warming effect of each molecule of CO2 decreases significantly (logarithmically) as its concentration increases. This is one reason why there was no runaway greenhouse warming when the concentration of CO2 was approaching 20 times that of today. This inconvenient fact, important though it is, is kept very well hidden and is rarely mentioned, for it undermines the theory of future catastrophic climate change (Hoskins 2014).

The truth is: we are paying these extortionate prices for the privilege of having ‘clean electricity’. Did you know that when the wind farms stop, due to lack of wind, or are switched off due to high winds, the owners still get paid and WE FOOT THE BILL! Some time ago the owners of 10 wind farms were paid more than £3million EACH to shut down their turbines when the National Grid feared too much energy would be generated, thus overloading the system!!! Under the U.K. “constraint” payments process wind farm owners can ask for compensation for each megawatt hour of energy their turbines WOULD HAVE produced but DIDN’T! Check it out.

Dr Jake - with all due respect you are talking about something outside your competence. You clearly do not understand the thermodynamic principles and you just not have grasped how to operate and control a heating system with a condensing boiler. As per your invite - augmenting the central heating with an electrical resistive heater is ridiculous and bad advice. Sorry. You could not do better than browse the Heat Geek YT channel to educate yourself. You could even recommend it to others.

@@DrJakesVeryBritishReviews If you got to the Heat Geek channel you will learn why. But briefly to answer the question directly there needs to be a boundary established before I answer. 1. Understand that the heat loss from your building depends on three key values and two of them are variable in real time. a. The fabric of the building (its insulation value) - how rapidly or otherwise heat energy flows in or out of the building. b. The outside temperature (real time variable). c. The actual temperature inside the house.(real time variable) 2. Essentially the larger the difference between inside and outside temperatures the greater the heat loss and the more energy you need to introduce into ‘the system’. So the only time your advice would arguably make some sense is: If gas and electric KW/hr pricing was equal (if you could distribute the heat in the same way as your wet system). Or if you had a super insulated (passivehaus) with extremely small heat losses AND there was insufficient heat input required to run a gas boiler sensibly (example only a couple of KW/hr input required) and the boiler was constantly cycling on and off.(which can be had for the boiler).
