    Interesting stuff. Are you monitoring humidity in the house? As you reduce drafts you are reducing air flow so the moist air inside doesn’t get replaced with less moist air from outside (well not so much) the more moisture in the air the more chance you have of getting damp spots where there are cold spots. Very complex subject that may be worth a video.

    Thanks for that video. I was interested in your final comments about temperature settings (room stat and boiler). You must have a different make/model of wife to me. Mine wouldn't be very happy with 20c and running the boiler at 46c would mean the house warming up in about a week and legionella bacteria going rampant in the hot water cylinder.

      Thanks for watching Graham. We have our hot water heated by the eddi rather than the gas boiler and it's set to 65ºC as standard. It maybe as the cold weather hits harder we will increase the thermostat to 21 - 22ºC.

      @@johntisbury I have considered an eddi but with our 6.9kWp panels located in NW England there isn't enough sun at this time of year to make an impression on the house electricity usage and keep one EV topped up. The situation might improve in spring/summer so I may try that next year. In the meantime heating the water with gas is the cheapest option, sadly.

    Very helpful video, though i can't afford a new door, i put a thick thermal curtain in front of our door, which cuts the drafts out, using your toilet paper stick trick, led lights though some are cfl lights and will replace with led when they blow, our biggest problem is the age of the house ( 1940's ish) , though may be moving to a bungalow soon,
    And if and when we do, i will look upon insulation in the loft and seals on the windows, though the loft with have to be done by the trade as i am disabled

    Good work John 👍 What's you logic for leaving the gas boiler on 24/7? Everything I've ever read says only heat the house when you actually want it warm i.e. operate the boiler on a timer. No need for the whole house to be at 20 degrees in the middle of the night when you're tucked up and fast asleep in bed 😉

    • @johntisbury
      @johntisbury  2 ปีที่แล้ว +1

      Thanks Mark.
      A great question re my boiler logic. It turned out to be flawed logic! My initial thoughts were because we'd dropped the boiler temperature to its lowest setting it was running like a heat pump, low and slow so keeping it running 24/7 would help to maintain that core temperature. However, since November last year we have kept the same boiler setting and run it on a timer (on at 8am off at 10pm) and the house has stayed the same temp and used less gas.

      @markcole1473 2 ปีที่แล้ว

      @@johntisbury Ahha, I wondered if that might be the case. It (running the heating 24/7 is more efficient than letting the house go cold then heating it back up when you want it) seems to be a persistent "myth" that has been around for ever. Perhaps it's the gas companies perpetuating it 😉

    I’ve been getting by with just a spot laser thermometer. You’re making me want a thermal camera!
    I’m thinking of a new data acquisition project. Using my raspberry pi to measure difference between inside and outside temperature. I could then correlate temperature decay rate with temperature difference. Then as part of a long term plan, each improvement to the building fabric can then be objectively measured in relation to temperature decay rate vs temperature difference.

    • @johntisbury
      @johntisbury  2 ปีที่แล้ว

      It's a great idea. The thermal camera certainly helps to pinpoint where the issues are and where no action is required. Makes it a bit more targeted. Great idea on the longer term before and after measures too. A little more scientific than mine.

    Paid someone to change the seals on every window in the house this week. Also changed the front door. I suppose that not so much of a coincidence given this channel is all about eco-efficiency. It’s like a new home. We were going to change the windows but were told we have great window and the benefits would be minimal. I’m impressed we were “sold” windows unnecessarily.
    Now on to our next project. #Attic insulation.

      Good advice , lubricate your window hinges often with silicone spray not oil , work it into the joints by moving the opener back and forth , it stops the joints seizing and pulling the sash tight against the seals , most of the time draughts are caused by lack of maintenance , after 40 years of fitting windows ive seen it all , most customers think windows and doors look after them selves , give them some TLC and they will last years

    • @johntisbury
      @johntisbury  2 ปีที่แล้ว +1

      Thank you for watching. They are ideal for maximising solar gain and reducing the heat in the summer as the louvres can be adjusted to bring in more or less sunshine. You can also hing them right back away from the window which I do in the winter when there is any sunshine, again to maximise solar gain. We do notice a difference when we open the louvres on a cold day, it is considerably colder next to the glass.

    Looks like a goldmine of info, looking forward to this. Questions to everyone trying to retrofit their homes to near passivhaus standard, what measures are you taking for air changes and elimination of condensation/humidity? And how much cost difference is there from installing Positive Input Ventilation against the systems needed if you're sealed up air-tight?

    • @johntisbury
      @johntisbury  3 ปีที่แล้ว +1

      This is a great point. I'm looking at heat and humidity sensors to automatically trigger heating / ventilation in the longer term. We're nowhere near air-tight so no risk of mould, condensation or stale air.

      Thanks Michael, it's a very valid point about air circulation. We are nowhere near passive house standards in terms of air tightness so don't think lack of circulation will be a problem. MHVR is currently a bit of a mare to retrofit, I'm sure neater and better solutions will come along in the near future.

      @@johntisbury I thought the same thing.
      And yes, the massive whole house recirculators would require a lot of plumbing.
      But you could look at the idea of just the bathroom for a start. You already have one extraction out.
      I take it the fan is in the loft.
      So all you would need to do is add a small single room recirculator add an extra hole in the bathroom roof and an extra hole outside note these need to be a minimum of 1 m apart.
      Which then brings me to each room. I figured I only need to do the bedrooms so I could put one above each bedroom.
      I've only installed the one in the bathroom to date. I don't have any data to work with yet as the bathroom is still being renovated
