    Yes, I avoided the heat recovery system for the shower waste, turbines for the rainwater down pipes and the solar panel following the reflective sun off the moon. But still considering the turbine driven by mains water

    Been there, done that, got the tee shirt. When you tap the barrow it crumbles like tissue paper. Most startling one though is either when you use too big a bucket and drop a ton on it and flatten it, or use it as a brazier and the tyre explodes. Those were the days....

    This situation would require your neighbours to enact a party wall agreement if they achieved permission and wanted to start the work: The Party Wall etc Act 1996: New building on the boundary line between neighbouring pieces of land (Section 1 of the Act) https://www.gov.uk/government/publications/preventing-and-resolving-disputes-in-relation-to-party-walls/the-party-wall-etc-act-1996-explanatory-booklet

    No. Totally uneducated me. Actually @Onoffin 1984 I could only receive the BBC World service on the radio.

    I understood that most people who die in fires die from smoke inhalation- thank goodness.

    The only way I know to stop rodents entering a building is to have it completely covered in something that they cannot chew through and keep holes no bigger than about 10mm. A lot of pipes through walls are not properly sealed around.

    As my brother says it's not if it's how much! We only use about 7000kW a year.

    Yes each individual property has its own drawbacks and benefits. No one size fits all! I could not sensibly position the ASHP on an outside wall so it is on a flat roof!

    Hmm. I noticed last week that either I cut all of my foam pipe insulation short 4 years ago or it has shrunk.... I understand your quote above to be true. Hence sealing all cut edges....

    Thanks. Better than a quiz over Christmas!

    Hi @puntloos I could not name one but if you have an external wall to the office I know there are some available in the market, and that sort (in and out external wall would be most sensible rather than ducting across the universe) Other people here will be able to help. (My guess is search single room MVHR or AIRCON). M

    It no longer squeaks

    Now this is fun! What's the passmark?

    I think your right about the maths. Espically as I think you can only use about 35% of a batteries capacity. I use this one for PV calculations: https://www.google.com/url?sa=t&source=web&rct=j&url=http://re.jrc.ec.europa.eu/pvg_tools/en/tools.html&ved=2ahUKEwjewPf1qfXzAhVSsKQKHXFiC_UQFnoECB8QAQ&usg=AOvVaw2-K48UEog42OCvQZSZqZxU Tricky on mobile to use otherwise ok.

    Surely @zoothornif you live in the wild west its warmer than 5C over Night??

    I turn the ASHP control to "no demand" when not in use. Last night here on the Isle of Wight the low was 12C what was your outside temprature at 2.30am that causes your ASHP to need to defrost??? Our antifreeze will go down to minus 8? AM I missing something?

    Then IMHO I think you will only get success from an independent system in the office using an inlet and exhaust and air sealing the door if you have an MVHR.

    The design I am work is intended for heating and cooling, but it is not without its challanges.

    Yes. Honest. After I finished insulating it.

    Hi ashp, mvhr, pv, ev and duct water coils. I am just starting to bring all the above elements together in our bungalow and wanted to run the works on a blog on Buildhub. In order to show my appreciation of this site I have funded buildhub and PMed @newhome as requested. I have also PMed @BuildHub to ask about setting up a blog. I hope that the volenteers on buildhub will be able to help find the time so I can document what I'm doing. Also as I go I hope that feed back from the members will help me when I struggle. Here's where I am at present: Marvin

    I'm also with ProDave. The outside temp has to be below 8C and or windy. otherwise we slowly overheat. If I was burning 1000W continual this place would cook. I mostly view the electricity I use in the house as creating heat in the building ( apart from charging the car, ASHP and outside lights). All cooking, Internet, TV, washing and dishwasher have this effect. The other item I'm working on is the solar gain: although only for short periods it requires as much power per hour to keep the place cool as heating does per hour in the dead of winter.

    My MVHR has to be balanced between air coming into the building and air going out. It also mixes the temprature in the building air with the temprature of the outside air coming in, OR, expells the inside air temprature and just supplies outside temprature air into the building. If your have the same set-up my thoughts would be: You could push the hotter air out of your office by supplying outside temp air in, however where will it go? Into the rest of the building. Will this be ok during the summer when the air coming in could already be 25 degrees C? My utility room is always to hot. I only extract the air from the room. In the winter my MVHR recycles the heat as in my first paragraph and in the summer expells the heat.

    I don't think anything is missing. Builders have been doing this with FPP info for years... except they usually change bits to make it look different.
