  1. I believe the rules are changing here, but when we sold our second home, the gain between purchase price and sale price was reduced by the proportion of time we lived in the house as our primary home. Plus two years. The reduced gain was then subject to CGT allowances and rates.

    Heating System Boost

    No experience, but it looks like a toy to me. Tiny surface area and small fan dumping 1kW is likely to be noisy in a quiet bedroom. One of the reviews mentions that.

    PP Conditions

    Not in my case. I suspect they rely on someone complaining and then comparing it to the PP conditions by exception. Just don't upset your neighbours - they may not have seen the conditions but might complain if your hardcore spills into the road. Cheapest is likely to be tarmac or waste concrete (e.g. surplus from a pour elsewhere) over the appropriate solid core. 'Half-decent' is tricky, your hell could be my heaven. Blockwork tends to be most expensive, though I am sure others will chip in with more expensive options - like gold-plated taps, I did not believe they could exist when I first heard of them!

    Warm downstairs but cold upstairs

    We have a similar arrangement. As a precaution I fitted an inline direct heater to bedroom MVHR supply. I think it is 1kW. It is controlled by a thermostat on the landing. So when very cold the inline heater will fire up and works well. I also leave bathroom towel rails on 24 x 7 at the lowest setting, maybe 30C, this works well.

    Many ways to set up an ASHP

    Makes little sense to me. Defrost is part of the design, so I can not see why the need avoid it. Direct electric heating gives COP of 1. As long as you stay above this even with defrosting you are saving money.
  7. You might be right. In my mind the grey area is that PP makes the land valuable as a separate property, not as part of the main residence. Not saying I am right, just how I read it.
  8. Re IHT, your parents' estate will only be liable if the total value exceeds £1m. (This full £1m figure will apply from 2020/21). So this may not be a major concern if the £650k house is the major asset. Allowance is £325k per person plus £175k for primary residence, per parent. If I understand it, provided parent 1 passes on the whole estate to parent 2, then parent 2 can benefit from double the allowance when they pass it on. Them gifting you the land might be more troublesome from a CGT perspective. At point of transfer, they will come under jurisdiction of CGT at the open market value of the land. So if the market value is above 2 x £11,700 allowance (assuming they do not use the allowance elsewhere), they become liable for tax. The 7 year rule only applies to IHT - separate to CGT. The land "sale" also brings SDLT into consideration - tax is payable if the value exceeds the £150k nil band. Once you own the land, then you might also come into a CGT liability. I am not clear how this might work, I guess if you move from one main residence to another within the allotted time it should be OK, however in this case you are buying land and not a house so do check on this aspect. Also, how likely that you can build and move in within 18 months of the transfer of the asset - it is possible, but might be tight.

    Nuenta Energy Blade - Water Source Heat Pump

    Not my experience at all. Ours can heat to 50C regardless of outside temperature. Sunamp for storage is a separate subject, 50C is too low for the regular PCM, and the 34C PCM is not hot enough for DHW. We use a 300l cylinder, the only downside is that recovery time is slow with our small heat pump.

    Which ASHP are set up to cool

    Seems right, I get around 4 when heating and 3 when cooling.

    Which ASHP are set up to cool

    Hitachi user. You enable cooling by a link change which is in the delivered documents. I use an original Hitachi controller for heating and cooling, it has the ability to program automatic switchover. Note that cop while cooling is not as high as when heating.

    Optimum use of PV

    Are you intending the ASHP to heat the Sunamp? (Bearing in mind you need a high-temp ASHP to do that, an ordinary one will not reach the phase change temp) Some considerations: 70l of buffer water is tiny. One shower will deplete most of it Heating using ASHP / PV / direct electrical will struggle to maintain more than 1 shower when your hot water store runs out Hence you need to size your store based on a likely scenario 8 showers within 1 hr means storage for 8 showers -> approx 20-25kWh but 4 showers in the morning and 4 in the evening means you can halve your storage I understand Sunamps are modular units and allow partial heating, e.g. you can 'switch off' cells when only 2 of you and switch them on when you have guests. Probably worth checking with Sunamp how this works. PV becomes a bonus source of electrical energy that you can optimise as follows: First priority is to use the PV in your house - appliances timed to run on sunny days, or EV car charging Next priority is to supply the Sunamp - use circuit 1 on your solar diverter Last priority is to pre-heat the buffer - use circuit 2 of solar diverter If all above are satisfied, you export the excess You can experiment with buffer temperature to avoid overheating your house. Your ASHP will support 2 circuits, so you can have DHW higher (to allow Sunamp to store the energy) and buffer lower (to supply UFH or pre-heat DHW). The solar diverter is important. For instance the Immersun has ability to sequence between 3 loads. The example above uses 2 loads. On sunny days, you sequence Sunamp > buffer. On gloomy days any spare PV drives the ASHP.

  14. You could claim they are fitted light fittings which are definitely covered.
