Morning all survived getting to 58.
@Dan! Hope your not putting an electric motor in the Lotus ???
Can you do deals here in France as we have Oil heating currently ?
We have the original Potterton boiler in our house, built in 1987. Horrendously inefficiency I suspect but the things just go on and on.
One point I have with these new more efficient boilers is that I understand that the efficiencies assume a well insulated house, which means that the temperature differential between the input and output doesn't need to be so great. (ie Radiators don't need to be so hot to keep the desired room temp).
Certainly in our place, this is not the case and we have to crank up the output temp to maintain room temp. When run like this , I understand that these new condensing boilers lose their efficiencies.
Happy to go back to school though.

So have we! Not quite as venerable - 29 years or so. Getting serviced tomorrow. I'm presuming that cost savings will take years to pay for a replacement.

Hiya!
Something to bear in mind is that temp and heat are two different things. High temps are inefficient, regardless of the tech. So rather than turning the temp up, increase the volume of heat instead. Easy fix is to increase the size of the heat emitters.... Get some bigger rads.
Underfloor heating for example has a flow temp of around 25-30c. But effectively turns the whole floor area into a radiator, and heats a house very effectively and consistently.
At the opposite end of the scale, a soldering iron is probably around 300c, but tiny. So even though it's got a really high temp, it would never heat a room.
Indeed, our 16th C Cattle Barn has underfloor heating. Its just warm to the touch but the rooms stay at 21' no matter how cold... small rads in old house were scalding but the down stairs would take days to get to 19'.

They tend to faint at the heat too.Do the cows not provide pretty good heating? As they're quite large they presumably emit a reasonable amount of heat. I suppose they're also powered by organic raw materials and emit quite a lot of waste gas and hence are not very environmentally friendly, but unlike more traditional methods of heating your house you can eat also milk them and eat them. They're definitely more versatile in that regard.

Hi Dan, you've cerainly given me some food for thought that's for sure! When we moved into this place 7 years ago (two days before Chrismas day) it was literally like a morgue. Air temperature in the lounge was just 6 degrees on that Christmas day. The reason were as follows:- The old heating system was completely inadequate; the radiators got nice and hot but the total heat output needed to fill the volume of space meant that it was completely hopeless. So we had to install a completely new system with 3 times the number of radiators to heat the volume of air needed to be comfortable. This was against the backdrop of having lath and plaster covered 2ft thick solid stone walls, including the internal room walls, a draughty suspended wooden ground floor, poor loft insulation and massive 9ft x4ft original single glazed victorian sash windows in the ground floor rooms. The floors on the ground floor were draught proofed as best we could with rubber sealing strips, the windows overhauled and all fitted with draft proofing seals and the loft had 1ft thick of insulation fitted which has made some difference. But heat wise it's still a very leaky house.You may doubt it, but I do it all day every day. It's just a case of knowing how.
I could get you up to £18,000 in grants, leaving you around £3k to pay for a £21k system, which would undoubtedly deliver the amount of energy you require. It's quite a small system compared to what I often work with.
I've just spec'd a system for 21 apartments over 6 floors, for minus £430k. Yep, they're being paid £430k to install the system. Easy when you know how.
But anyway, sounds like you're happy burning dead dinosaurs, so I'll leave you to it.
