Hi @SteamyTeaI knew I could rely on you for a more objective view. The principle of local generation and local storage of energy is one I ascribe to. However, still using the grid. As I have commented before we produce more than double the energy for all our home needs from our PV system it's just that we can't practically store the energy produced in the summer to use in the winter.

So a tried and tested technology?

There you go!

This may help. https://www.gov.uk/government/publications/permitted-development-rights-for-householders-technical-guidance/permitted-development-rights-for-householders-technical-guidance#class-d-porches Height: references to height (for example, the heights of the eaves on a house extension) is the height measured from ground level. (Note, ground level is the surface of the ground immediately adjacent to the building in question, and would not include any addition laid on top of the ground such as decking. Where ground level is not uniform (for example if the ground is sloping), then the ground level is the highest part of the surface of the ground next to the building.)

I think your about to get a blast of experience any minute.... (not just from me!) Trial and error is ok but there are calculators out there that you can use for free to get reasonable figures. Have you used this one: https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html M

Yes you are of course right! I am used to smaller properties....

I thought the size of the instant hot water boilers which also supply heating were always sized related to the hot water flow requirement for the property! This almost always means the boiler can easily heat the property as that requires less power? However the water flow rate into the building needs to be taken into account as well. Good luck M

Hi @yoclick Plus one on all the advice above. I would do some research to confirm the location of the future ASHP. Its not just the water pipes to be considered; will your electricity supply and cabling handle the load to the same destination? In principle it is best to have the ASHP unit as close as possible to the hot water tank/heat sump/buffer tank (length of pipe wise), you should have any hot water storage all within the thermal envelope of the building, all external pipework needs to be insulated to within an inch of its life. Yes the system will work if you don't do these, but the system will run less efficiently until its replaced or improved. Good luck M

Hi @Garald I assume you own little land between your window and the source of the noise. If it's vehicular noise is it airborne or impact or both?

Hi @James94 Always good to have a fall on the lawn to stop standing water. We found that it was very important to have the fall on the clay below as well. If not the clay underneath will act as little ponds. M

Hi @kestrel Yes. Not so good to heat all those bricks if it an external wall...

Hi @kestrel Couple of other options: Blow a fan towards and at the bottom of the wood burner. Pull the fire out more altering the flue. If all the heat is heating the bricks you have a heat sump. Is the fire on an external wall? M

Hi @gavztheouch In my humble opinion labour rates, material costs, property prices, energy costs and interest rates are all unstable and there are too many variables at play at the moment to make a determination as to which will do what when. However one thing that is not going to suddenly change is indebtedness, from a personal, local government, country or world view point. With this in mind I conclude that things cannot avoid becoming financially tougher, even though I feel that interest rates will go down from here (mainly because of the economic hit on indebtedness due to interest rates) and may well go seriously up along with inflation later next year. You may have noticed that Travis Perkins has issued a warning about trading conditions, and I can think of three others associated with property that I expect to hear the same from.

I always preferred resin stone as it tends not to flex. I always put silicone around the waste connection top of the trap, both sides of washer underside of tray and top of tray.

I'm pretty sure I've seen cables for household car charging points being advertised with the power and data cores in the same cable.... https://www.cef.co.uk/catalogue/products/5243696-3-core-6-0mm-cat5-ev-cable-black-cut-length-sold-by-the-mtr?gclid=CjwKCAjwvfmoBhAwEiwAG2tqzKXgR2l1fhLNZr6BMSCtxQOX5knV9vbL1mAtyUlgWK_NRyrDdYrD_xoCV-YQAvD_BwE&gclsrc=aw.ds not sure how these work...

I have also insulated suspended timber floors by cutting hatches in the floor and crawling underneath installing 100mm PIR between joists and 50mm PIR across all the joists held up with battening. All gaps foam filled. A better choice if there is enough room below the floor and you have to do the whole ground floor which is inhabited. W e just lifted a corner of the carpet cut holes in the right places and off you go. It took 2 people 7 days each to do 100m2.

I wonder if people are using the D4 flooring adhesive? I have used D4 on about 150 square meters of 22mm chipboard tongue and groove(T&G) boarding with no problem. I also use screws about 3 times the length of the chipboard and 22mm moisture resistant T&G boards. https://uk.westfraser.com/our-products/caberfix/caberfix-d4/

yes its the effect on their fillings

Hi @SteamyTea Nice idea but... during the winter, with our 5.12kW array, some days we produce less than 1kWh the whole day. On December 11th 2022 the tally was 1.2kWh, however as the diverter only diverts unused energy and we use about 2-300 watts per hour during the day this resulted in nothing going into the hot water heating. However on the 12th Dec we produced 7.4kWh and on the 7th of December 13.94kWh. However on the 3rd December 0.41kWh. My rambling point is that heating the hot tank in the winter higher than 60C means we can make it last about 3 days. 99% of 365 days is - call it 4 days: Our entire plot surface area is too small to accommodate enough panels to supply enough power for heating the water for 361 days in the year.

We have no mains gas so we ran our renovated home on LPG for about 3 years which was fine (remember it's well insulated and airtight home) but we then grouped technology together with an ASHP, PV and solar power diverter which has worked out to be the most efficient. LPG was about £600 a year including hot water. ASHP is about 1600kW a year excluding hot water ( well about 80% is via the PV diverter).

Hi @nod You are right. but I think of it in terms of until gas becomes more expensive and therefore HPs are cheaper to run.... Also peoples lifetime habits ( and the UK's housing stock!!!) needs to change away from burning hot radiators, windy and uninsulated homes, towards a low heat requirement with airtightness and better insulation. Either that or we learn to wear knitted jumpers again...

These Tudor bricks are the crap I am having to use... I have exactly the same problems... oh and bent ones!

Statistics published today by the U.K. Department for Transport (DfT) show that in 2022 85% of the car drivers in Great Britain broke the law by driving faster than the speed limit in 20mph zones. The choice to live dangerously is available to everyone.
