    I can't read as well as you. 

    Red Rum, you're a twat.
  • so lets move on to radiators..

    I'm replacing mine to make the existing heating better, and future proof if I ever go for a heatpump.

    I've gone for modern style convectors, which is a shame as they aren't 'heritage', mind you neither were the old ones.

    Then I read an article that says cast iron rads are actually eco, but is this just a sales pitch?

  • If your home isn’t well insulated and airtight, then a heat pump will never work.

    Saw something about aluminium, pricey tho. One of the complaints about ashp is the speed of getting hot, aluminium seems to fix that
  • It's vital with a traditional house (solid wall, pre 1920 built with lime etc) to never use modern materials, gypsum, cement, plastic paint etc.

    The exterior walls in particular should never be allowed to trap moisture as this will lead to damp, rot and poor insulation. 

    Never be tempted to 'tank' or have dpc injections, these are a huge waste of money and mask any possible real issues, if they ever existed. 

    A thermal imaging camera is worth considering to hire to find issues. At least a laser thermometer to point around. Stop draughts with lime and or Oakham.

    Consider buying a new book The Warm Dry Home by Peter Ward. This explains looking after an old building in detail and dispels the myth of the damp proofing con artists who cause most problems. 

    I agree about avoiding ASHPs but would thoroughly recommend a wet UFH system as long as the build-up includes around 120mm of foamed glass. This is essential IMO.

    Peter Ward has posted a lot of YouTube videos explaining and demonstrating the correct treatment of houses suffering from damp, often made much worse by attempted fixes using inappropriate modern materials, such as cement pointing, plastic paints etc. Highly recommended if your house is of lime construction.
    I've pulled plastic paint off the front of mine and will redo this summer with breathable paint. Also spent a happy few weekends chipping out cement pointing and redoing with lime. Very satisfying and really not that difficult.

    I've been replacing all my radiators/whole heating system, have mostly gone for aluminium. They are so much more efficient than the old style Stellrad type panel/convector and pump out some serious heat. Yes they are pricey, but worth it in my view. They seem to take a lot less water, hence why they are considered more cost effective as less water being heated.

    got most of mine from the radiator company https://www.theradiatorcompany.co.uk/radiators/aluminium-radiators You want to check what BTU's you need in each room and make sure you spec accordingly and of course balance them.

    EDIT; I actually ordered them through a local plumbers merchant who gets about 35% off the prices listed on their site.

  • A tale from years ago….

    My mum and her husband owned a very old house in Penshurst - it was listed, and had one of the oldest opening windows in the UK - English Heritage turned up one day, and said the wooden frame was rotten, and had to be replaced - my mum’s husband said ‘ok, I will get a local carpenter to fix it’

    Oh no, no, no - that was not an option

    English Heritage said that a man from Scotland would come down and make a frame using the correct wood and using the tools that the frame would have been made with originally

    He came down, took 3 days, he stayed in a hotel - all of it had to be paid for by mum and her husband - over £15,000 😳

    Suffice to say they don’t live in a listed building now !!
