How To Insulate A Suspended Floor And Central Heating Pipes

[DavidMarfe]

Here's videos of my efforts and progress so far I've almost completed the whole ground floor now just the remaining of the hallway I can't do till I remove the old stair but I have completed the entire downstairs central heating pipes all now insulated. So my next project now is building the new loft conversion. Looking forward to demolishing the cowboy loft. Remember if your thinking about getting a loft conversion done Avoid John W Slaytor his website loftco.co.uk

I recently did a test on my central heating I turned it on for 30 minutes and timed the restart time from when it switches off and turns back on to regulate the temperature before I started the downstairs pipe insulation it was off for 50 seconds now it’s off for 1 minute 15 seconds that’s a 25 seconds longer the heating system remains the extact same temperature. I still have three meters of central heating pipe downstairs to wrap and the rest of the hallway and kitchen floor to insulate and ofcourse the upstairs and the new loft conversion to do so. I believe when the downstairs is completed the central heating system will be on standby for 1 minute 30 seconds when downstairs is completed and when the second floor pipes are wraped who knows. But I look forward to the results theses improvements make.

At least you found the central heating system bypass valve in video2 1m-55seconds

2:27 Seconds the boiler is off for now during a heating cycle and is only on for 30 seconds

Before starting Insulating the floor and wrapping the central heating pipes the boiler heating cycle would be off for 50 seconds after doing the dinning room and wrapping the pipes under the room the off cycle was 1 minute 15 seconds but the heating on cycle was 1 minute 7 seconds

So when having the boiler on for the second hour of two hours the heating would be on for 28 minutes of that and be on for 32 minutes now the boiler is off for 44 minutes and on for only 16 minutes roughly that's 30% less gas usage now.

So its estimated I will save money in 4 years when the costs are repaid with the savings of the efficiency but I did it mainly keep my feet warm and lower my carbon foot print.

So for every £1 I put in the boiler I will now save 30p when I get the loft done my efficiency should improve again. I replaced the windows in my house 3 years ago but I never recorded any data before I change the windows now I wish I did as I was told if you change the windows you only save 15% on heating whilst doing the floor its 25% and the cost of doing it is lower so the return is faster. It take 20 years to get a return on new windows and by that time your need to replace the panels of glass during that time. I'm trying to improve my houses thermal efficiency by up to 70% So here's hoping.

Insulation is great for stopping heat getting out and I'm impressed you're being so scientific about it!
We insulated the lounge floor, didn't check the temperatures before, but now if I move the thermometer from though height to on the floor the temperature reading only drops 0.3c. No more cold feet - although floor insulation generally saves less energy it stops cold spots.

Latest Update It's stayed nice and dry in my living room during the wet winter period and warm humidity doesn't go above 55% without heating on and temperature only drops 3C from 21C in 8 - 9 Hours So if I run the heating and turn off the temperature to 21C and shut down at 10pm when I wake up in the morning at 6am it's 18C when the outdoor temperature is 2C outside That temperature is only in the living room and dinning room as the rest of the house is 10 - 12C. So I really got to get the rest of the house up to standards now.
