Form is just the thermal performance of the heat losses areas divided by the floor area, in this instance. So a cube is better than an rectangular box, less glazing is better than lots.

@Jeremy Harris was going to fit a small cylinder as a backup to his SA. Was hoping he would post up some running cost numbers as a back to back comparison.

That does not really govern the heat losses. Form is more important than area.

Your consumption is in kW, which is power. Your actual consumption will be the area under the graph i.e. sum of power multiplied by time.

Close enough, and 60 to 70% will be used in the heating season, but don't forget that the real efficiency of a gas boiler is lower than the stated efficiency, so possibly 25% goes waste.

Get the beach towels out.

Yes, going to cost almost 2 quid to post it.

Welcome. As you are already living in the house, do you know your current energy usage? As you are on LPG, this could be a bit tricky to work out at first, but should be possible to calculate reasonably well. While very possible, I would never trust a company rep. What you need to know is the sCoP (seasonal coefficient of performance) as this is what your cash is really buying.

Apart from the recent Which report about internal air quality from gas hobs/cookers, an induction hob is so much better to cook on. Ovens are a bit more complicated as gas ovens have higher humidity, which can be a benefit. You will save the daily standing charge by not having a gas connection, but as the property is already connected, reconnection would not be prohibitively expensive.

Extraordinary claims require extraordinary evidence

I forgot that.

Could it be the sleeve the stat goes in is bent and touching the element?

Similar sort of savings I have made. I wish I had started doing it seriously earlier in my life.

No idea, I think I would have heard if they had failed badly. St. Mary's Hospital Walkway was removed after about 30 years of usage, but that was part of a total redesign. The Mosque dome had higher powers keeping it up.

Really I have been digging down for a decade or more. But worth it, considering that I was using 11 MWh.year-1 when I moved here. Not everyone has gas.

First things first. Do a heat loss model of your hows. If you look around our Boffin's Corner, you will find a heat loss spreadsheet. Once you have filled that in, you can change an element i.e. thermally better windows, more floor insulation, and then start to make decisions. You can take your time doing this as we are currently heading out of the heatings season. Learning a bit of school thermodynamics is helpful as well, it makes the terminology understandable. A very useful thing to do do is to record your energy usage. If you have Smart Meters this is easy, if not, then you can get meters, or even manually daily reads. Data is so useful, hard to overstate just how much it helps.

Welcome. Was there not a book about all this. https://en.wikipedia.org/wiki/A_Year_in_Provence

@Pocster! You corrupting people again. (Got asked today about being a tour guide in a processing plant, so this is actual useful information, but smutty banter is more fun)

Do a forum search, I have specified the difference before and it saves totally detailing this thread.

As it is a kitchen, I assume it is only used, mainly, for cooking/meal times. If this is right, the temperature will fluctuate wildly. So UFH may not be the best heating solution. Plinth heaters may be a good match as they can heat the air, which the hob extractor is removing, fairly rapidly. The output can be matched to the extractor air flow. They can also be put on timers/thermostats to keep the overall room temperature within acceptable limits, even cooling if needed. Noise should not be a problem as kitchens are noisy anyway.

No, that is clear cut and easy to understand. Just a shame that many people refuse to accept the difference and argue that it is the tools used to fit them that is how they get their names. Useless tools.

Elements? Luminaire is the correct term for the complete light fitting.

Is it slit into deep invoices, or clumped together as one invoice? This, I think from my rudimentary contract law studies at university, makes a difference. It is akin to buying a pint of milk at Tesco in the morning, then buying some teabags in the afternoon. Then, when you go to make some tea, you find the milk is off. You can't go back to Tesco with the milk, but the teabag's receipt and expect a replacement/refund for the milk.

Is it getting hotter than the others, maybe a ventilation/airflow problem.

Sporty Ford Diesel isn't it.
